Specifications & Features

The sample that Toshiba submitted is the 512 GB model. This series is equipped with Toshiba MLC written NAND flash memory from the A15nm node. The new SSD is as Toshiba claims a new mid-range SSD solution that provides excellent performance and endurance for mainstream users.

Toshiba will release four models, 128 GB, 256 GB, 512 GB and a big daddy 1024 GB version. Due to the architecture and memory channels used, the 128 GB model will be a notch slower for writing, albeit that is a very modest performance difference. This is pretty much the rule of thumb for any brand BTW. Still, a 128 GB SSD performing at 550 MB/sec read and 485 MB/sec write performance remains fast, very fast.

It is a tiny bit confusing, but Toshiba OCZ makes mention of endurance, it varies based on capacity though. But if we take the 512GB model as example, you'll get a proper 296 TB Written. if you do the math spread out over the 5 years under warranty that would be 296.000 GB / 60 Months = 4933 GB per month. Divide that by 30 days and you have an allowance of 165 GB writes per day.  For the 256GB that's half that number, but for the 1024 GB version that's even doubled up.
Now, do not confuse this with a specific lifespan as this is a warranty indication. These SSDs might easily double or triple that lifespan and writes. With proper drive wearing, amplification and all the safety features at 50GB/day you could even get 15 years of lifespan out of the product before the NAND cells are exhausted.
