Plextor expands PCIe 4.0 SSD product line: up to 7000 MB/s

Plextor is a division of Kioxia and owns Unfold Its M10P series SSD lineup has PCIe 3.0 x4 interface and extreme performance. The series now includes 512GB, 1TB and 2TB models with a rated peak sequential read speed of 7000 MB/s. These drives are powered by InnoGrit’s Rainer controller, which guarantees the ultimate power efficiency because its power consumption does not exceed 3W.

Plextor M10P series solid-state drives with PCIe 4.0 x4 interface are based on Innogrit’s IG5636’Rainer’ controller (Multi-core, NVMe 1.4, 8 NAND channels, NAND interface up to 1200 MT/s, 3W, 12nm) and Kioxia’s 3D TLC NAND memory. M10P SSD comes in M.2-2280 form factor, equipped with a large aluminum heat sink (M10PG) or no heat sink at all (M10PGN), and a HHHL card form factor (M10PY) equipped with a large heat sink and some RGB LEDs.

From a performance point of view, Plextor’s M10P 1TB and 2TB drives are rated for sequential read speeds of up to 7000 MB/s, sequential write speeds of up to 5000 MB/s, 650K random read IOPS, and up to 530K random write IOPS. In contrast, the maximum sequential write speed of the 512GB model is 4000 MB/s, and the maximum random write speed is 530K IOPS. The SSD is designed to write 0.35 drive writes per day (higher than some cheap competing SSDs for client PCs) and has a five-year warranty.

Plextor launched its first PCIe Gen4 drive much later than its competitors. To some extent, this situation can be explained by the company’s acquisition by Kioxia. However, with the uncertainty brought about by the transaction, the company also transitioned from InnoGrit to the controller, which requires some additional work to ensure that Plextor’s firmware technology and the new controller work properly.

For those who want to know why Plextor, which has relied almost exclusively on Marvell controllers for many years, decided to use InnoGrit controllers after becoming part of Kioxia (which has supported Phison for many years), there is a simple explanation. Many people in the Marvell SSD business unit have left the company for Innogrit. These people have a good relationship with Plextor’s engineers and have a deep understanding of their requirements. Therefore, Plextor uses Innogrit controllers, at least for now.
