Specifications & Features

The sample that OCZ submitted is the 240GB model. This series is equipped with Toshiba TLC NAND flash memory from the A15nm node. This product is a notch slower in writes overall though due to that TLC NAND Flash memory, but overall the previous generations are sitting roughly in the same domain performance wise. However OCZ applied a strick, they made an SLC writable buffer sized a few GB. Meaning for the duration of a couple GB that SLC segment will be used for writes (pretty much as an internal NAND cache). This will speed up the write process significantly. Obviously once you run out of that SLC NAND cache you'll bump into slower TLC based writes. As OCZ claims this doubles up write performance over the previous generation product.


OCZ will release four models, 120 GB, 240 GB, 480 GB and a big daddy 960 GB version. Due to the architecture and memory channels used, the 120 GB and 240 GB models will be a notch slower, albeit that is a very modest performance difference. This is pretty much the rule of thumb for any brand BTW. Still, a 120 GB SSD performing at 550 MB/sec read and 450 MB/sec write performance remains fast, especially if you keep the price in mind as, starting at 240GB, you are seeing ~30 EURO cents per GB. Over time with volume availability you can save to shave off another 10%.

  • SATA 3 - 6Gbp/s Interface
  • A15nm Toshiba TLC NAND Flash
  • 7mm form factor
  • 120 GB, 240 GB, 480 GB and 960 GB models
  • Performance and endurance without compression/loss of usable capacity
  • Power consumption IDLE 0.830W / Active 4.80 W
  • TRIM support
  • 3 Year Warranty


It is a tiny bit confusing, but OCZ makes mention of endurance, it varies based on capacity though. But a nice 55 GB/day of host writes for 3 years under typical client workloads with a 240GB model is good. 55GB x 365 days x 3 years = 60 TB written guaranteed. Now, do not confuse this with 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 easily get 10 years of lifespan out of the product before the NAND cells are exhausted. For example, a recent test from a colleague with a Vector 150 (19nm) rated 20 GB/day for 5 years went as far as 844 TB Host Writes with 1313 Terabytes on NAND writes before the drive went belly up. That's 121 years at 20 GB/day and thus over 5000 P/E cycles. Then again, we have seen end-users write like 5 TB per three months, if you are such a power user then you probably should not look at a value series ok?
