FCC Chairman Ajit Pai Will Resign on January 20th

The federal government has started to adjust to the reality of Joe Biden’s inauguration as the 46th President on January 20th. A lot of things are going to change that day, including the leadership of the Federal Communications Commission (FCC). Current Chairman Ajit Pai has announced he will resign from the commission on that day. “It has been the honor of a lifetime to serve at the Federal Communications Commission, including as Chairman of the FCC over the past four years,” Pai said, announcing his departure. 

Ajit Pai began his career as a lawyer in the Department of Justice and at Verizon. In 2011, he joined the FCC under Obama as one of the commission’s Republican members. The FCC has a long tradition of balance with the party holding the presidency nominating three commissioners and the other party getting two. When Donald Trump took over in 2017, Pai was elevated to Chairman, and he did all the things people expected him to do. 

Within a year, Pai had led the new Republican majority of the commission to roll back the Title II reclassification enacted under Chairman Wheeler in 2015. That effectively killed net neutrality for the duration of the Trump administration. And this wasn’t a by-the-books policy change for the FCC. Pai gave interviews and wrote extensively on his rationale for the change — he even participated in a rather tasteless net neutrality parody video with The Daily Caller (see above). Despite a bomb threat during the December 2017 vote, Pai succeeded in reversing net neutrality. Subsequently, he and fellow Republican commissioner Brendan Carr advocated for FCC regulation of social media.

FCC Chairman Ajit Pai does not usually dress like a discount mall Santa.

Pai also oversaw the merger of Sprint and T-Mobile, accepting the argument that this deal was necessary to accelerate 5G deployments in the US. Sprint is now being slowly digested by T-Mobile, which has access to a mountain of 2.5GHz spectrum that’s ideal for 5G. That’s a problem for Verizon and AT&T, both of which are lacking strong mid-band spectrum for 5G. 

Partisanship was a hallmark of Pai’s tenure running the FCC, but the commission also took action that everyone can get behind. The FCC supported efforts to roll out robocall blocking in 2018, and earlier this year it created a national 988 suicide prevention hotline. 

The President-Elect’s team has yet to talk about its plans for the FCC, but Pai’s departure makes things easier. On January 20th, President Biden can designate a new Chairperson, and the smart money is on long-time commissioner Jessica Rosenworcel.

This Giant Claw Could Soon Clean Up Space Junk

Humanity launched the first satellite in 1957, and since then we’ve put thousands of objects in orbit with little regard for the future. Along with about 3,000 active satellites, we now have 900,000 pieces of space junk larger than 10 centimeters. The results could be catastrophic if even a tiny piece of debris collided with a crewed spacecraft or merely inconvenient if it hit a satellite. In either case, that’s something you want to avoid. Cleaning up space to prevent collisions is a tall order, but the ESA has just funded a giant space claw that could show the way forward. 

Most launch operators don’t usually go into a mission intended to clutter up the space around Earth. Nevertheless, defunct satellites, booster engines, and smaller bits of machinery can remain in orbit long after their useful life. Some objects will fall back to Earth naturally as their orbit decays, but the volume of space debris is still moving in the wrong direction, and space is about to get a lot more crowded with megaconstellations from SpaceX and others. 

To combat the increase in space junk, the ESA has awarded a €86 million contract to Switzerland-based ClearSpace SA to run the first-ever active debris removal operation. The ESA will provide expertise and money, but ClearSpace SA will do all the engineering and design work. It will also seek additional funding for the mission from commercial investors. 

The target of the ESA mission is a Vespa (Vega Secondary Payload Adapter), which was left in a 400-mile-high orbit since 2013 when it helped launch a Vega rocket in 2013. The team chose this object because its orbit and composition are well understood, and it’s about the size of a small satellite. 

The mission, known as ClearSpace-1, could launch as soon as 2025. The claw-shaped spacecraft will rendezvous with the Vespa debris and lock onto it with the grapplers. After that, it simply drags the object down into the atmosphere where it and the claw burn up. You would, of course, need a lot of these devices to clear Earth’s orbital traffic jam, but this is just an initial test. If ClearSpace-1 is successful, the company can design more efficient versions of the claw for capturing junk. 

Only time will tell if ClearSpace’s approach to removing space junk is viable, but we will need to do something. The more cluttered space becomes, the more dangerous it is. Some scientists even worry that a chain reaction of space collisions know as the Kessler effect could render the space around Earth unusable for years or decades.

How Do SSDs Work?

Here at ExtremeTech, we’ve often discussed the difference between different types of NAND structures — vertical NAND versus planar, or multi-level cell (MLC) versus triple-level cells (TLC) and quad-level cells (QLC). Now, let’s talk about the more basic relevant question: How do SSDs work in the first place, and how do they compare with newer technologies, like Intel’s non-volatile storage technology, Optane?

To understand how and why SSDs are different from spinning discs, we need to talk a little bit about hard drives. A hard drive stores data on a series of spinning magnetic disks called platters. There’s an actuator arm with read/write heads attached to it. This arm positions the read-write heads over the correct area of the drive to read or write information.

Because the drive heads must align over an area of the disk in order to read or write data, and the disk is constantly spinning, there’s a delay before data can be accessed. The drive may need to read from multiple locations in order to launch a program or load a file, which means it may have to wait for the platters to spin into the proper position multiple times before it can complete the command. If a drive is asleep or in a low-power state, it can take several seconds more for the disk to spin up to full power and begin operating.

From the very beginning, it was clear that hard drives couldn’t possibly match the speeds at which CPUs could operate. Latency in HDDs is measured in milliseconds, compared with nanoseconds for your typical CPU. One millisecond is 1,000,000 nanoseconds, and it typically takes a hard drive 10-15 milliseconds to find data on the drive and begin reading it. The hard drive industry introduced smaller platters, on-disk memory caches, and faster spindle speeds to counteract this trend, but there’s only so fast drives can spin. Western Digital’s 10,000 RPM VelociRaptor family is the fastest set of drives ever built for the consumer market, while some enterprise drives spun as quickly as 15,000 RPM. The problem is, even the fastest spinning drive with the largest caches and smallest platters are still achingly slow as far as your CPU is concerned.

How SSDs Are Different

“If I had asked people what they wanted, they would have said faster horses.” — Henry Ford

Solid-state drives are called that specifically because they don’t rely on moving parts or spinning disks. Instead, data is saved to a pool of NAND flash. NAND itself is made up of what are called floating gate transistors. Unlike the transistor designs used in DRAM, which must be refreshed multiple times per second, NAND flash is designed to retain its charge state even when not powered up. This makes NAND a type of non-volatile memory.

Flash cell structure

The diagram above shows a simple flash cell design. Electrons are stored in the floating gate, which then reads as charged “0” or not-charged “1.” Yes, in NAND flash, a 0 means data is stored in a cell — it’s the opposite of how we typically think of a zero or one. NAND flash is organized in a grid. The entire grid layout is referred to as a block, while the individual rows that make up the grid are called a page. Common page sizes are 2K, 4K, 8K, or 16K, with 128 to 256 pages per block. Block size therefore typically varies between 256KB and 4MB.

One advantage of this system should be immediately obvious. Because SSDs have no moving parts, they can operate at speeds far above those of a typical HDD. The following chart shows the access latency for typical storage mediums given in microseconds.

SSD-Latency

Image by CodeCapsule

NAND is nowhere near as fast as main memory, but it’s multiple orders of magnitude faster than a hard drive. While write latencies are significantly slower for NAND flash than read latencies, they still outstrip traditional spinning media.

There are two things to notice in the above chart. First, note how adding more bits per cell of NAND has a significant impact on the memory’s performance. It’s worse for writes as opposed to reads — typical triple-level-cell (TLC) latency is 4x worse compared with single-level cell (SLC) NAND for reads, but 6x worse for writes. Erase latencies are also significantly impacted. The impact isn’t proportional, either — TLC NAND is nearly twice as slow as MLC NAND, despite holding just 50% more data (three bits per cell, instead of two). This is also true for QLC drives, which store even more bits at varying voltage levels within the same cell.

The reason TLC NAND is slower than MLC or SLC has to do with how data moves in and out of the NAND cell. With SLC NAND, the controller only needs to know if the bit is a 0 or a 1. With MLC NAND, the cell may have four values — 00, 01, 10, or 11. With TLC NAND, the cell can have eight values, and QLC has 16. Reading the proper value out of the cell requires the memory controller to use a precise voltage to ascertain whether any particular cell is charged.

Reads, Writes, and Erasure

One of the functional limitations of SSDs is while they can read and write data very quickly to an empty drive, overwriting data is much slower. This is because while SSDs read data at the page level (meaning from individual rows within the NAND memory grid) and can write at the page level, assuming surrounding cells are empty, they can only erase data at the block level. This is because the act of erasing NAND flash requires a high amount of voltage. While you can theoretically erase NAND at the page level, the amount of voltage required stresses the individual cells around the cells that are being re-written. Erasing data at the block level helps mitigate this problem.

The only way for an SSD to update an existing page is to copy the contents of the entire block into memory, erase the block, and then write the contents of the old block + the updated page. If the drive is full and there are no empty pages available, the SSD must first scan for blocks that are marked for deletion but that haven’t been deleted yet, erase them, and then write the data to the now-erased page. This is why SSDs can become slower as they age — a mostly-empty drive is full of blocks that can be written immediately, a mostly-full drive is more likely to be forced through the entire program/erase sequence.

If you’ve used SSDs, you’ve likely heard of something called “garbage collection.” Garbage collection is a background process that allows a drive to mitigate the performance impact of the program/erase cycle by performing certain tasks in the background. The following image steps through the garbage collection process.

Garbage collection

Image courtesy of Wikipedia

Note in this example, the drive has taken advantage of the fact that it can write very quickly to empty pages by writing new values for the first four blocks (A’-D’). It’s also written two new blocks, E and H. Blocks A-D are now marked as stale, meaning they contain information the drive has marked as out-of-date. During an idle period, the SSD will move the fresh pages over to a new block, erase the old block, and mark it as free space. This means the next time the SSD needs to perform a write, it can write directly to the now-empty Block X, rather than performing the program/erase cycle.

The next concept I want to discuss is TRIM. When you delete a file from Windows on a typical hard drive, the file isn’t deleted immediately. Instead, the operating system tells the hard drive it can overwrite the physical area of the disk where that data was stored the next time it needs to perform a write. This is why it’s possible to undelete files (and why deleting files in Windows doesn’t typically clear much physical disk space until you empty the recycling bin). With a traditional HDD, the OS doesn’t need to pay attention to where data is being written or what the relative state of the blocks or pages is. With an SSD, this matters.

The TRIM command allows the operating system to tell the SSD it can skip rewriting certain data the next time it performs a block erase. This lowers the total amount of data the drive writes and increases SSD longevity. Both reads and writes damage NAND flash, but writes do far more damage than reads. Fortunately, block-level longevity has not proven to be an issue in modern NAND flash. More data on SSD longevity, courtesy of the Tech Report, can be found here.

The last two concepts we want to talk about are wear leveling and write amplification. Because SSDs write data to pages but erase data in blocks, the amount of data being written to the drive is always larger than the actual update. If you make a change to a 4KB file, for example, the entire block that 4K file sits within must be updated and rewritten. Depending on the number of pages per block and the size of the pages, you might end up writing 4MB worth of data to update a 4KB file. Garbage collection reduces the impact of write amplification, as does the TRIM command. Keeping a significant chunk of the drive free and/or manufacturer over-provisioning can also reduce the impact of write amplification.

Wear leveling refers to the practice of ensuring certain NAND blocks aren’t written and erased more often than others. While wear leveling increases a drive’s life expectancy and endurance by writing to the NAND equally, it can actually increase write amplification. In other to distribute writes evenly across the disk, it’s sometimes necessary to program and erase blocks even though their contents haven’t actually changed. A good wear leveling algorithm seeks to balance these impacts.

The SSD Controller

It should be obvious by now SSDs require much more sophisticated control mechanisms than hard drives do. That’s not to diss magnetic media — I actually think HDDs deserve more respect than they are given. The mechanical challenges involved in balancing multiple read-write heads nanometers above platters that spin at 5,400 to 10,000 RPM are nothing to sneeze at. The fact that HDDs perform this challenge while pioneering new methods of recording to magnetic media and eventually wind up selling drives at 3-5 cents per gigabyte is simply incredible.

SSD controller

A typical SSD controller

SSD controllers, however, are in a class by themselves. They often have a DDR3 or DDR4 memory pool to help with managing the NAND itself. Many drives also incorporate single-level cell caches that act as buffers, increasing drive performance by dedicating fast NAND to read/write cycles. Because the NAND flash in an SSD is typically connected to the controller through a series of parallel memory channels, you can think of the drive controller as performing some of the same load-balancing work as a high-end storage array — SSDs don’t deploy RAID internally but wear leveling, garbage collection, and SLC cache management all have parallels in the big iron world.

Some drives also use data compression algorithms to reduce the total number of writes and improve the drive’s lifespan. The SSD controller handles error correction, and the algorithms that control for single-bit errors have become increasingly complex as time has passed.

Unfortunately, we can’t go into too much detail on SSD controllers because companies lock down their various secret sauces. Much of NAND flash’s performance is determined by the underlying controller, and companies aren’t willing to lift the lid too far on how they do what they do, lest they hand a competitor an advantage.

Interfaces

In the beginning, SSDs used SATA ports, just like hard drives. In recent years, we’ve seen a shift to M.2 drives — very thin drives, several inches long, that slot directly into the motherboard (or, in a few cases, into a mounting bracket on a PCIe riser card. A Samsung 970 EVO Plus drive is shown below.


NVMe drives offer higher performance than traditional SATA drivers because they support a faster interface. Conventional SSDs attached via SATA top out at ~550MB/s in terms of practical read/write speeds. M.2 drives are capable of substantially faster performance into the 3.2GB/s range.

The Road Ahead

NAND flash offers an enormous improvement over hard drives, but it isn’t without its own drawbacks and challenges. Drive capacities and price-per-gigabyte are expected to continue to rise and fall respectively, but there’s little chance SSDs will catch hard drives in price-per-gigabyte. Shrinking process nodes are a significant challenge for NAND flash — while most hardware improves as the node shrinks, NAND becomes more fragile. Data retention times and write performance are intrinsically lower for 20nm NAND than 40nm NAND, even if data density and total capacity are vastly improved. Thus far, we’ve seen drives with up to 96 layers in-market, and 128 layers seems plausible at this point. Overall, the shift to 3D NAND has helped improve density without shrinking process nodes or relying on planar scaling.

Thus far, SSD manufacturers have delivered better performance by offering faster data standards, more bandwidth, and more channels per controller — plus the use of SLC caches we mentioned earlier. Nonetheless, in the long run, it’s assumed NAND will be replaced by something else.

What that something else will look like is still open for debate. Both magnetic RAM and phase change memory have presented themselves as candidates, though both technologies are still in early stages and must overcome significant challenges to actually compete as a replacement to NAND. Whether consumers would notice the difference is an open question. If you’ve upgraded from NAND to an SSD and then upgraded to a faster SSD, you’re likely aware the gap between HDDs and SSDs is much larger than the SSD-to-SSD gap, even when upgrading from a relatively modest drive. Improving access times from milliseconds to microseconds matters a great deal, but improving them from microseconds to nanoseconds might fall below what humans can really perceive in most cases.

Intel’s 3D XPoint (marketed as Intel Optane) has emerged as one potential challenger to NAND flash, and the only current alternative technology in mainstream production. Optane SSDs don’t use NAND — they’re built using non-volatile memory believed to be implemented similarly to phase-change RAM — but they offer similar sequential performance to current NAND flash drives, but with vastly better performance at low drive queues. Drive latency is also roughly half of NAND flash (10 microseconds, versus 20) and vastly higher endurance (30 full drive-writes per day, compared with 10 full drive writes per day for a high-end Intel SSD).

Optane1

Intel Optane performance targets

Optane is now available in a wide variety of formats, including server expansion cards, personal SSDs, and as add-on cache for accelerating a conventional hard drive. Intel has also pushed Optane as a form of direct-attached memory with far more capacity available in total than DRAM, at the cost of higher access latencies.

Android 12 Could Include Major App Compatibility Improvements

Google’s pitch when it launched Android was openness and customization. Unlike Apple, it released its mobile OS under open source licenses, allowing device makers to modify it. This disconnected approach helped Android become the most popular computing platform on Earth, but it’s been hard to reach Apple levels of polish and consistency. Google has attempted to centralize chunks of Android to address this over the years, and a major component called ART is set to get this treatment in Android 12. The result could be vastly improved app compatibility, which is sure to make everyone happy. 

Until a few years ago, every update to Android phones required rebuilding the OS from scratch with Google’s latest codebase. That started to change with the addition of Project Treble in Android 8.0 Oreo. This architectural change makes vendor code forward-compatible so new OS updates can plug in without any low-level changes from Qualcomm and other chipmakers. Project Mainline came along in Android 10 to further modularize the OS and deliver core system updates via the Play Store.

According to a new note in the Android open source code, Google plans to move the Android Runtime (ART) into Mainline with Android 12. That means it will be able to update this vital system component across potentially all new Android devices starting next year. ART is vital because, without it, your phone wouldn’t know how to run any of your apps. 

ART came to Android in 4.4 KitKat and became mandatory a year later. ART is what’s known as an ahead of time (AOT) compiler. It takes the bytecode from apps and compiles it into native instructions, which are ready for your phone whenever you open the app. ART replaced the Dalvik VM, which was a “just in time” compiler that converted code on the fly and was rather slow as a result. 

If Google begins requiring OEMs to include a Google-signed ART component on phones, Google could push updates to it on all certified Android devices. Android app compatibility has come a long way, but there are still times that a phone might render an app incorrectly or break background services because of OEM system modifications. A universal Google-updated ART module could make apps more consistent across devices, which is good for users and great for developers who constantly have to track down device-specific bugs. 

None of this is official yet — Google hasn’t announced ART’s inclusion in Android 12, but the project is ongoing in the open-source project. If it comes to fruition, Android apps could get a big usability boost.
