2 petabytes and counting; I'm doing science and I'm still alive.

It is now down to two drives at The Tech Report, only the Samsung 840 Pro and a HyperX 3K which was brought in to replace an model with no stamina have reached the 2 petabyte mark and are still going.  The 840 Pro has now used 61% of its used block reserve due to flash failures and while the Sandforce compression has allowed the HyperX to hit this mark with only 1.4 petabytes actually written it has still had 31 sectors reallocated and 2 uncorrectible errors.  That puts the HyperX in a difficult spot in that while it is still writing data it is not truly trustworthy anymore.  The drive speeds have remained remarkably consistent though the 840 is slowing down somewhat over time, check out the actual benchmark results in the latest update to The Tech Report's torture test.

"Our SSD Endurance Experiment has reached an astounding two petabytes of writes. Only two drives remain, and they're coping very differently. We've checked in on their health and performance to see how each one is holding up."

Heavy peta-ing; fondling SSDs in a bad way

The Tech Report's attempts to test SSDs to destruction have hit the 500TB mark, with three two-bit MLC NAND drives and one three-bit TLC model all trying to survive.  They are using raw SMART data to keep track of sectors reallocated from the spare area to replace flash which has died due to repeated usage.  So far the Samsung 840 with its three bit TLC has suffered the most loss of sectors but like the other drives it has not shown much performance degradation.  There have been a few other bumps in the road during the tests, check out the full story here.
