At CES 2017, Plextor announced their next SSD product line. Dubbed the M8Se, these will be restricted to NVMe SSDs with 15nm 3-bit-per-cell TLC of Toshiba manufacture, ranging from 128 GB, 256 GB, 512 GB and 1TB capacities leveraged by Marvell's Eldora controller.

The new mid-range NVMe SSD uses a new heatsink design (slight cost-reduction when compared with the one the M8Pe carries), that Plextor says will improve cooling by up to 20% - convenient, since throttling does happen with NVMe based SSDs - and particularly with Marvell's Eldora controller - as it did with Plextor's M8Pe line of SSDs. The card also features blue accent lighting. Plextor will also sell a heatsink-less M8PeGN model in the M.2 form factor.As of now, Plextor rates these SSDs with the following specifications: the 128 GB and 156 GB models carry 512 MB of LPDDR3 DRAM, whilst the 512 GB model ups that amount to 1024 MB and the 1 TB model doubles it again to 2048 MB. Sequential read speeds are rated at 1,850 MB/s for the 128 GB SKU, 2,400 MB/s for the 256 GB, and 2,450 MB/s for the 512 GB and 1 TB models, with 570 MB/s read speeds for the 128 GB model and 1,000 MB/s for the remaining three capacities. Random read and random write performance is rated at 135K/80K for the 128 GB model; 205K/160K for the 256 GB one; and 210k/175K for the 512 GB and 1 TB models, with endurance ratings starting at 80 TBW for the entry-level 128 GB SKU and doubling with capacity (160 TBW, 320 TBW and 640 TBW respectively).

Plextor will launch eight product SKUs with two different types of M8Se drives. The M8Se doesn't have an M.2 model with a heatsink at this time, this being restricted to the M8SeY add-in card, but that may change before the product launches in June or July, with a lower price-tag than their previously-released M8Pe SSDs.
