Aimed at read extensive applications and to be available in 128GB, 256GB and 512GB capacities, the Toshiba Q300 Pro is based on Toshiba's own TC85NC1000 controller paired up with Toshiba 2-bit-per-cell (MLC) NAND. It has a sequential read of up to 550MB/s while sequential write performance is set at 520MB/s. The 4K random performance tops out at 92k IOPS for read and 63k IOPS for write.
The Toshiba Q300 Pro SSD also comes with SLC caching, QSBC Error Correction, Patrol Read and Thermal Control Sensor features and have lower 3.3W load and 125mW idle power consumption.
The Toshiba Q300 SSD, on the other hand, is based on Toshiba's TC358790 controller paired up with 3-bit-per-cell (TLC) flash NAND. It has a slightly higher sequential performance, reaching up to 550MB/s for read and 530MB/s for write, while random 4K performance is set at up to 87k IOPS for read and 83k IOPS for write. This one will be available in 120, 240, 480 and 960GB capacities.
