Though these are samsung pm1633a, so you need to check you have an up to date firmware version. How many power on hours is it showing? (32k hour bug).

I reached out to them via ebay. They said that the drive is indeed 7.68TB. That the sticker that says 960GB is incorrect and was applied by a vendor prior to them (SPD) receiving the unit. Sounds like they knew about the sticker mixup.

SMART stats seem to match that of a 7.68TB,
Code:
=== START OF INFORMATION SECTION ===
Vendor:               SAMSUNG
Product:              PA33N7T6 EMC7680
Revision:             EQHE
Compliance:           SPC-4
User Capacity:        7,680,475,267,072 bytes [7.68 TB]
Logical block size:   512 bytes
Physical block size:  4096 bytes
LU is resource provisioned, LBPRZ=1
Rotation Rate:        Solid State Device
Running f3write/f3read on it now to verify it is 7.68TB. So far it seems like SPD is right and that the drive is legit!
Finally a good plot twist !

Anyone checked these out? Micron 7450 Pro U.3 7.68TB with >-= 97% life each for $750 each (3 available). Listing location is in Sunnyvale, seller has good ratings. If I didn't already more than enough storage I'd be game: Facebook

Wow, we're at ~$400+ for 3.84TB SATA :-(
I do not expect things to improve dramatically anytime soon.
We may get some SSDs when AI dumps it one way or the other, but it would likely be in a different form factors (NVMe in U.2 etc).

I worry about the health of those drives. Locally someone was selling a handful of U.2 drives that were at 23/24PBW drive endurance and only like 3 years old. I was told they were retired them because they were too close to 0% life remaining. And they were still over $100/TB

This is unusual. I've bought quite a bit (100s) of used enterprise SSDs and even 70% life remaining was very unusual.
Most were in 90%s, and over half in 99-100% range.

I guess now we can see another round of reuse ;-) :-(

Yeah these recyclers very rarely sell SSD under 90% health, usually disclose it, and I have never been sold a <75% health undisclosed. TBW is only half of the story. An enterprise SSD can take a lot more TBW if they are sequential, than their random TBW specification (because of write amplification).

The problem with the AI SSDs is that they will be mostly huge capacity QLC SSDs and I don't know how those age independently of usage.

Right now, Micron's market cap has increased 10x in one year, and they clearly haven't added much production capacity. So this is them hiking up their margins like if there was no tomorrow, jensen style. So this is not only not about to get better, it is about to get worse in the short term (6-12 months).

The adapters aren't too bad. Currently from $8 on up including shipping. I got 4 for $18 in the past.

Bought some new 400GB Innodisk ones 2 years ago, $24 each. Haven't found a use for them yet.
