EU [WTB] Intel Optane P1600X

[azzurro]

Hi,

I'm desperately looking for P1600X Optanes, they've almost completely disappeared from the market.
If anyone would be willing to sell me one or two drives, I'd be very grateful.
Specifically I'm looking for either the 58GB or the 111GB version, idk if they were different sizes available, tbh.

Thanks!

Out of curiosity, why are optane drives that popular? I understand they have a massive DWPD but for such tiny sizes, you would get the same writes with a 3.2TB drives rated for 3 or 5 DWPD, plus you get a bit more room.

Extremely low latency.

For databases I presume? Because it has to be used for some sort of cache. You can't store much data in such a tiny space. What is the value added vs a RAM cache?

RAM cache is not permanent storage and loses data in case of power loss. Usually you use it for the WAL (Write-Ahead log) of databases, which is one of the most limiting factors for write latency

And I presume the log is then persisted at a later stage on some larger media? Most optane drives I see are fairly small.

i personally use it for ZFS SLOG, so lots of very small transactions which must be committed as fast as possible and must not be lost in case of power loss similar issues.
3D XPoint has extremely low latency.

Unfortunately, they are discontinued/retired (along with many other M.2 form factor Enterprise/Datacenter SSDs).

FYI .. here are the capacity and part numbers (noticed you put 111GB):

58GB = SSDPEK1A058GA01
118GB = SSDPEK1A118GA01

Even just for regular filesystems if you have a bunch of small files the performance difference is notable, the read latency is so low you don't need much concurrency to get high performance, and they are available larger in other form factors. When the p1600x was cheap it was a fine choice for boot drives, just because 2280 M.2 drives with power loss protection aren't common, the performance is just a very nice side benefit.
