Plextor Also Unveils M8Pe Series PCIe SSDs

Plextor also unveiled the M8Pe lines of SSDs that take advantage of the 32 Gb/s PCIe interface. These include the M.2-2280 form-factor M8PeG series, and the PCI-Express add-on card form-factor M8PeY series. Both drives come in sizes of 128 GB, 256 GB, 512 GB, and 1 TB; and are driven by Marvell 88SS1093 series processors, wired to Toshiba-made MLC NAND flash memory.

The 128 GB variants of both drives offer up to 1,600 MB/s reads, with up to 500 MB/s writes, with up to 120,000/130,000 IOPS R/W 4K random access; the 256 GB variants offer up to 2,000 MB/s reads with up to 900 MB/s writes, and 210,000/230,000 IOPS random access; the 512 GB variants offer up to 2,300 MB/s reads with up to 1,300 MB/s writes, and 260,000/250,000 IOPS random access; while the 1 TB variants lead the pack with up to 2,500 MB/s reads, up to 1,400 MB/s writes, and 280,000/240,000 IOPS random access.

Lite-on already showed an M2 SSD with Marvell 88SS1093 that is doing 3268MB Read and 1782MB Write with 400.000iops. Is Plextor holding back or is it just using slow NAND to keep cost down? Any ways with these speeds we are already reaching the max bandwidth of M2 interface, whats next M3 with 8 PCIe lanes or will they wait for PCIe 4.0 that will effectively double the speed of M2 with four PCIe 4.0 lanes.

4GB/s minus overhead is the max bandwidth. Still a while to get there considering we are still using SATA 3 with 540MB/s crappy speed

Well, the US Missile command still uses 8-inch floppy drives so...

If you mean SSD i have one Samsung 950 pro 512GB and one Samsung 950 Pro 256GB but i rather have one M.2 1TB SSD that does over 3GB/sec with 400K IOPS like the Lite-on.

Okej, i thought the overhead was 20% like on PCIe 2.0 but when i checked PCIe 3.0 only have 1.54% overhead so as you say there is still a bit to go until maximum bandwidth 3.94GB/sec is reached.

Yeah, i miss the good old days. Unbelivable that you still can destroy the world with 8-inch floppy discs.
