R.I.P Intel 330.
600 TiB of nand write isn't a lot for a 120GB drive.

Double post.
Hey guys, quick question. What do you think of the health of this drive? SF2282 with Intel Async 25nm NAND. Raw Read Error rate fluctuates from time to time, I've seen it as low as 103. Only 3 retired blocks, and no other obvious issues.
Attachment 130674
Drive looks fine to me. Only 2 reallocated blocks, which is nothing for the SSD.
As long as the normalised value for raw error rate stays above 50, the drive isn't failing in that test either.
I haven't stopped the 830 in nearly five months, but I'm thinking about pulling it down and running some tests on it before resuming testing.
There are lots of questions I have about its performance after 5PiB. It's already got 5.3million GiB on it.

More block failures -- 0 program, 12 erase, so 5 are read failures -- not a good sign. It's been over 138 days and 16 minutes since the last stoppage... I just can't seem to bring myself to stop it now to perform some testing on the 830.
Doesn't the 830 use sub 32nm Toggle flash? Some review sites show 830 use 27nm Toggle-Mode 1.1 MLC. Do the 830 nand vary depending on production date and so some older units have 32nm+?Quote:

Another read failure for the 830;
73728 reallocated sectors, 18 reallocation events (12 erase, 6 read, 0 program). And it seems to be getting faster on average after months of steady average performance.
Doing some testing on my Vertex 4 512GB. What units is the RAW host writes value in? Sectors? Bytes? It's written 800~900Gb so far.

If it were in sectors, you'd have 4TB in host writes.
any news on planned 840 TLC tests?
Well, I would test an 840 if I could buy one .... but I can't ... not for love or money at the moment.
ETA at newegg for 840 TLC is Tuesday.
I never thought I'd be excited about a TLC drive, but I am genuinely interested in getting my hands on the 840 TLC.
It is in sectors. That's really strange, apparently the WA has been really high because I've really only written about 1-2TB over the few weeks I've had this drive.
