If you follow our coverage closely you know, were running endurance tests on an OCZ Vector SSD with 256 Gigabyte capacity. In the beginning we didn't know how long it will take until we run out of P/E-cycles on the NAND flash but several days into the test we're starting to understand what we're actually dealing with.

When it comes to their Vector SSD the maker specifies this drive for 20 Gigabyte writes per day, which translates into 35 TBW (Terabyte written) in total. Seven days into testing the drive we've already written 45 Terabyte on the NAND flash memory, meaning we've already surpassed the 35 Terabyte mark by an additional 10 Terabyte.

Apart from the TBW value we're having a close look at the S.M.A.R.T. data and especially the "Remaining Life" value. At 45 Terabyte written it indicated 90 percent, meaning writing 45 Terabyte made this value go down by 10 percent. It starts to look like this SSD is not just made to cope with 35 Terabyte written, it seem this drive will survive even ten times that. We're actually rather surprised to see that SSD makers calculate endurance with such generous factors.

We will definitely keep you posted on any further updates and every day we're getting more curious to find out how much this drive can actually take.
