Launched at the same time as the standard Crucial T700 (which we reviewed here) is the version that comes with a factory-fitted low-profile heatsink. On sale for about £350, what performance is on offer, and is it worth it over the non-heatsink version?
The T700 is built around the world's first consumer Gen 5 controller, Phison's PS5026-E26. For the T700, the eight-channel controller is used in combination with Micron's own 232-layer 3D TLC NAND Flash. Also from Micron is the LPDDR4 DRAM IC used for caching duties (1GB per 1TB of NAND flash).
At the time of launch, the T700 line is made up of just three capacities; 1TB, 2TB (the drive we are looking at here) and a 4TB flagship model. As for performance, the 2TB and 4TB models are rated at up to 12,400MB/s and 11,800MB/s for Sequential read/writes respectively while the 1TB drive is rated as up to 11,700MB/s for Sequential reads and up to 9.500MB/s for writes.
As for random 4K performance, the 2TB and 4TB drives are rated as up to 1,500,000 IOPS for both reads and writes with the 1TB drive's performance quoted as up to 1,350,000 IOPS for reads and 1,400.000 IOPS for writes.
Crucial quote an endurance figure for the 2TB model of 1,200TBW with figures of 800TBW for the 1TB drive and 2,400TBW for the flagship 4TB model. The range is backed by a five-year warranty.
