Here is some information from my notes on the Samsung 470 that should help you fill in some blanks for that column.


On 2011-08-20, the 64GB Samsung 470 SSD died with the error:

NexusDB: nxEnduranceTbl: INTERNAL: Error when reading from file
[E:\DATA\Endurance.nx1, error 21, The device is not ready]
[$2401/9217].

Also, the ASU error log was full of entries like:

08/20/11 3:01:15PM - Write error 5

It wrote a total of 525.607 TB before it died.

I tested it on a Core i5-2400 machine running Win7 x64

No overprovisioning

42GB static data (41992617078B)

2011-06-29 Started testing
2011-07-05 MWI exhausted at 59.35TiB, sa177 reached normalized 1 - raw 5017
2011-08-20 ended testing at 478.04TiB

113MiB/s average write speed during test

I guess the flash is rated for 5000 P/E cycles since sa177 (~MWI) raw value was 5017 when the normalized value reached 1

FINAL REPORT:
478.037 TiB, 1300 hours, sa177: 1/1/39078, sa178: 2/2/996, sa235: 99/99/2, 3.59 MB/s

Write errors continuously logged, ASU mostly unresponsive (waiting for writes to complete that rarely do?)
