Toshiba Memory calls PM5 and CM5 is the first enterprise SSD that uses a 64-layer flash memory 3D NAND TLC
Toshiba Memory Corporation (TMC) announced the development of solid-state drives PM5 and CM5, which is equipped with SAS and PCIe interfaces, respectively. The manufacturer calls PM5 and CM5 is the first enterprise SSD that uses a 64-layer flash memory 3D NAND TLC, stating that the development should be completed in the fourth quarter.
TMC PM5 drives size 2.5 inches will be offered with capacity from 400 GB to 30.72 TB. The use of architecture MultiLink SAS four ports will allow you to obtain sequential read speeds up to 3350 MB/s and sequential write speed up to 2720 MB/s Maximum performance for read operations random access declared equal to 400,000 IOPS.
Drives CM5 is equipped with two ports PCIe Gen3 x4 NVMe support. For these drives the manufacturer quotes the maximum performance on operations with random access. In record mode it is equal to 240 000 IOPS in the case of the model with resource 5 DWPD (complete rewrites per day) and 220 000 IOPS in the case of the model with resource 3 DWPD. Performance in read mode reaches 800 000 IOPS. Drives CM5 is scheduled to release capacity from 800 GB to TB of 15.36.
In addition to the resource models with 3 and 5 DWPD will be available models online 1 DWPD, and in a series PM5 — and 10 DWPD.
