The company's prototype SSD offers a lower cost and longer longevity than comparable MLC based SSDs.
Plextor has taken the wraps off a prototype Triple-level Cell (TLC) based NAND Solid State Disk that pairs Toshiba's 19 mm TLC NAND memory with a Marvel controller. Since TLC memory stores more bits per cell than Multi-level Cell (MLC) and Single-level Cell (SLC) based devices, its chips are physically smaller, require less power to operate, and so far have mostly been used in lower end memory cards where speed and reliability are not high priorities.
Plextor's new SSD goes against this trend by offering speeds in excess of 500 MB/s (read) and 400 MB/s (write), random 4k IOPS of 80,000 (read) and 72,000 (write), and better reliability than comparable MLC devices.
Though the SSD's release date, availability and price are still unknown, Plextor has announced that it will be available in 128 GB, 256 GB and 512 GB variants with 256 MB, 512 MB and 712 MB of DDR cache memory, respectively.
