The HPE datasheet says 0.5-0.6 DWPD, is this just ridiculously conservative?You can do 7-10 DWPD on all the cards just fine in most cases. It really comes down to your app any any write amplification. Even then, you're likely fine.

I'd go with @acquacow advice, he is an authority to me and many regarding those drives.The HPE datasheet says 0.5-0.6 DWPD, is this just ridiculously conservative?
Probably not the worst deal to miss. I bought the last one and received it today and it appears to be DOA. Can't see it in BIOS, Linux (dmesg), Windows (diskmgmt.msc) or via a USB to SATA adapter. Tried multiple PCs and even taped the 3.3V pin for giggles. Nothing.
Did you test the Drive also via an HBA such as LSI 9211-8i ?Probably not the worst deal to miss. I bought the last one and received it today and it appears to be DOA.

The drive I received doesn't match the serial number of the auction/CrystalDisk Info screenshots, so I contacted the seller about a return/refund.
I had my own fair Share of bad Sellers. From those that don't test, those that ship the wrong Item, pack stuff like **** (5mm cardboard anybody ?), etc.If you're the buyer, none of these excuses hold water.
I received a lot of Servers/Motherboards with unknown iRMC / IPMI Passwords. Boot Debian/Ubuntu, run IPMITOOL and reset. That's the easy Part IMHO, it takes less Time than complaining with the Seller.Allow me to add another. Those who ship electronics with unknown log in credentials. This one really pisses me off. More often than not seller is clueless when contacted.
I have never heard of this before now. I tried it, and the drive is recognized. I would not expect this behaviour from an Enterprise SSD, but you learn something new every day!Did you try e.g. the "Crucial Power Reset Trick" ?
OK, so it works now ? Weird indeed, but I thought it was worth a shot.I have never heard of this before now. I tried it, and the drive is recognized. I would not expect this behaviour from an Enterprise SSD, but you learn something new every day!
smartctl look ? Is everything fine ? Record it both before and after a Secure Erase and/or Firmware Update just to be sure.Weird indeed.I recently bought a Wattbox with unknown credentials. And guess watt (pun intended) resetting the device does not clear the user/PW. I contacted the seller and his reply was "You may have to purchase a device to get into it". I sent it back.
And yes, IPMI is not a problem, I can reset the PW in my sleep.
uboot Bootloader Password, but not many Users (unless running OpenWRT) will probably need that.binwalk and take a look with ghidra or something like that. Or flash a new one. But why bother, when that's not something that was agreed in advance (buying e.g. a Device "For parts or not working") for a very low bargain Price.Forgot to mention I did get it sorted out. I found a howto on the web that revealed the PW. I think it was https:/<ip address>/password. So much for security, lol.Weird indeed.
Was there CMOS Battery inside or what? I would expect, just like BIOS, that if you unplug the Battery then it would just clear everything.
But yeah, on a Switch, the Reset button does everything. Except possibly resetting theubootBootloader Password, but not many Users (unless running OpenWRT) will probably need that.
If it comes to worst, you need to open and use a Serial CH341A Programmer or similar, dump the Firmware,binwalkand take a look withghidraor something like that. Or flash a new one. But why bother, when that's not something that was agreed in advance (buying e.g. a Device "For parts or not working") for a very low bargain Price.
Apple trashcan bios PW is impractical to reset, etcI received a lot of Servers/Motherboards with unknown iRMC / IPMI Passwords. Boot Debian/Ubuntu, run IPMITOOL and reset. That's the easy Part IMHO, it takes less Time than complaining with the Seller.
Most Switches have a small Reset Hole.
I'm not sure which kind of Device you are referring to specifically that is so problematic to reset. I'm not saying I don't believe you or that it doesn't exist, but I don't think I ever came across it personally.
Many thanks for this, Seller accepted my offer of £130 well chuffed
