Toshiba is launching a trio of retail SSDs today armed with the company's own 3D flash memory. The TR200, available in 240GB, 480GB and 960GB capacities and presented in a standard 2.5in form factor, uses third-generation 64-layer BiCS flash 3D.
Let's take a peek at the spec first. The TR200's speed is limited by the SATA 6Gbps interface, and Toshiba is not planning to release it in other flavours - notably PCIe - soon. This has more to do with market segmentation than anything else.
The sequential read and write speeds are standard across the three capacities, and we have commonly seen 555MB/s and 540MB/s before. IOPS, a measure of how good the drive is when dealing with random, small files, is, again, where we'd expect an entry-level SSD to be.
Toshiba uses triple-level cell (TLC) memory to achieve the stated capacities with the minimal amount of physical nand. That can sometimes mean that endurance suffers, as you are writing to cells more often than on single- and multi-level-cell drives. However, advancements in wear technology mean that endurance is reasonable across all capacities, rising linearly through the range. Putting this into context, the 240GB is capable of sustaining of 60TBW, or 250 full drive writes. This is why Toshiba feels comfortable in arming it with a three-year warranty.
There's no drive encryption, however given that TR200 doesn't feature specific DRAM for buffering duties, like much of the competition in this space, Toshiba reckons active power is just 1.6W, or up to 60 per cent less than rival solutions. This doesn't matter much in a desktop machine, but slot it into a laptop and every watt counts.
