The drive stores date stamps as metadata ("last read") and maintains metadata in terms of groups of blocks wherein the blocks in any group share characteristics based on page sampling. This is because not all word lines in a die perform or act the same, e.g. top layers program slower but have...

A normal consumer drive will rely on the host clock and/or a power-on state to determine if flash needs to be read and reflashed. So, this requires more than passive power, although theoretically it's possible to have external devices that can wake drives. In real world use, people rely instead...

Arguably, yes, although with my resources I try to split drives by category of utilization (e.g. purpose) rather than performance tiers. For example, larger QLC drives make more sense as HDD replacement, write-few read-many, games, archival, backups and storage, etc, while a TLC drive can be...

This looks to be a 512GB Micron 2400. How fast are you downloading? This drive uses QLC and at this capacity (which is low) the cache is pretty small and QLC performance will be pretty terrible. To ballpark it, this flash is rated for up to 27 MB/s per die and you have four dies here so a max of...

There are 80Gbps TBT5 enclosures that pass x4 PCIe 4.0 lanes, that's about the extent of it. These will take Gen5 drives but they will run at Gen4 speeds. So a drive like the 990 PRO is just fine. Honestly, you won't be bottlenecked by that fast of an external connection as the actual native...

Should be even more efficient. Would be cool to see it tested at lower PCIe speeds.

682.4 MB/s per watt. This is over 50% more efficient than the 2TB Gold P31, if that puts things into perspective.

There's a difference between 2Tb TLC dies and 2TB TLC packages. Currently you can stack up to 16 dies in a package which, since there are 8 bits in a byte, means you can reach 2TB in one package with just 1Tb dies. That's the case here and 1Tb dies for TLC are fairly common these days. As it...

The 970 EVO Plus has twice the channels and a much smaller cache. Speed wise, I think we went from the two-plane V5/92L (~500µs tPROG) to four-plane V8/236L which at its rated ISSCC speed of 164 MB/s should be in the 390µs range. So, yeah, about 25% faster if it had the same size cache, but...

We did have x2 M.2 slots in the past on some boards and quite a few laptops. I've also seen x1/x1/x1/x1 bifurcation for SSDs over the PCH (ASRock board) as the southbridge is a PCIe switch in its own right. I think x2 might be a thing for some laptops with PCIe 5.0 and there are some AICs with...

We've had 1.33Tb QLC dies for a while now, technically, which would be up to 2.66TiB per package, but it's not really used that way often. In enterprise it is because Intel's "QLC" was taped out as 5-bit PLC at 1.66Tb per die (3.33TiB package). In QLC mode it's 1.33Tb dies, in TLC 1Tb dies...

External enclosures over USB will show as SCSI; they use the UASP (USB Attached SCSI Protocol).

Agreed. WD has or will have the 8TB SN850P available for the PS5 and this would work there, too. Some people want that much space and the PS5 has only one slot. Limited slots in some laptops and HTPCs, too. Desktop systems are starting to get a serious number of M.2 slots but this still a good...

Volatile pricing. Sometimes that does happen. Right now heatsink one is $149.99 on Newegg, without heatsink is $144.99 (w/promo).

This appears to be definitely more efficient, particularly as if you run this as Gen3 it would probably do even better than it does. I think the Gold P31 was surpassed a while ago in this category.
