![]() Intel uses the SM2262 in their own 760p SSD, and cheaper drives based on the SM2262 reference design are being sold by ADATA and HP. The WD Black and the Samsung 970 EVO showcase the strengths of a vertically integrated strategy with the NAND, SSD controller, firmware and drive all designed by the same company.Ī little lower on the price scale are several competitors based around Silicon Motion's second generation SM2262 controller, a huge improvement over their earlier SM2260 controller. The M9Pe shows us what the new WD Black would have been like if WD's new controller hadn't been ready and if they had stuck with the Marvell controller for another generation. The second-generation Western Digital WD Black uses the same BiCS3 3D TLC NAND as the M9Pe but features Western Digital's new in-house controller. Most of the competition for the M9Pe uses substantially different hardware. Our review samples are the 512GB M9PeGN (M.2) and the 1TB M9PeY (AIC), but we've also swapped the drives in the adapter card to present results for both capacities running as standalone M.2 drives and in the adapter with the heatsink and LEDs. Newegg is the only major online retailer selling the M9Pe, and they're not currently listing the 1TB M9PeY add-in card model. The versions with extra cooling carry a substantial premium. Since it first hit the shelves, prices on the M9Pe have come down to roughly match other top SSDs when comparing against the M9PeGN variant that lacks a heatsink. Half-height half-length PCIe add-in card (HHHL) ![]() Plextor M9Pe Series Specifications Comparison The five year warranty period and ~0.3 drive writes per day endurance rating are typical for this product segment. Overall, performance specs are a bit below other current high-end NVMe SSDs like the Samsung 970 EVO and Western Digital WD Black. The 256GB M9Pe still has distinctly lower performance specifications than the larger models, especially for write speeds. The 128GB option is gone from this generation because that would only use half of the controller's eight NAND channels. Plextor has managed to implement NVMe 1.3 features for the M9Pe despite using an older controller that was originally designed to target the NVMe 1.1 specification.Īs with other NVMe SSDs from this generation, the large 256Gbit or 512Gbit capacity of each NAND flash die hurts performance of the smallest drive capacities. The controller in the M9Pe is the same Marvell 88SS1093 "Eldora" used in the preceding M8Pe and M8Se SSDs, so the M9Pe derives almost all of its improvements from the upgraded NAND. This is Toshiba's first mainstream, mass-produced 3D NAND, branded by Toshiba as BiCS 3. This time it is Toshiba's 64-layer third-generation 3D TLC NAND. Like most Plextor SSDs, the M9Pe uses Toshiba NAND flash memory. Using Toshiba NAND and Marvell Controllers Aside from those cosmetic touches, the M9Pe is essentially the same as the Lite-On CA3 client SSD we reported on previously. The Plextor-branded retail NVMe SSDs also offer the cosmetic distinction of optional heatspreaders and add-in card adapters with heatsinks and LEDs. This often gives them an edge against companies that simply re-brand reference designs from the controller vendors, but as the biggest players in the SSD market are increasingly vertically integrated it is getting harder for Plextor to compete. Lite-On doesn't manufacture their own NAND flash memory or SSD controllers, so their primary means of product differentiation is through writing their own SSD controller firmware. Plextor is the retail SSD brand of Lite-On, one of the larger suppliers of SSDs for OEMs. The M9Pe was officially launched at the beginning of this year, but the M9Pe didn't hit the shelves until March, and supplies are still inconsistent. As with most SSD product lines, as a general industry wide implementation, MLC NAND is being abandoned in the transition to 64-layer 3D NAND. The M9Pe is the successor to both the M8Pe, which used Toshiba 15nm MLC, and the M8Se, which used Toshiba 15nm planar TLC. The M9Pe is the new flagship SSD from Plextor, and its first NVMe SSD to use 3D NAND flash memory.
