Plextor M7e M.2 PCIe SSD Tested, Over 1.3 GB/s On Tap

[btarunr]

Plextor showed off its upcoming M7e PCI-Express SSD in the M.2 form-factor, at CES. A successor to the M6e, which was designed to offer 770 MB/s sequential reads, with up to 580 MB/s sequential writes; the new M7e offers double the performance. Although Plextor didn't put out its own manufacturer-rated numbers, the drive was put through CrystalDiskMark on a live-demo, and compared to its nearest market rival, Samsung XP941.

Built around a Marvell 88SS9293 controller, with PCI-Express 2.0 x4 bus interface, the drive features Toshiba A19 MLC NAND flash chips. The drive was tested to offer 1411 MB/s sequential reads, with 1028 MB/s writes; compared to the 1136 MB/s reads and 928 MB/s writes, put out by the Samsung XP941. With these numbers, the drive is targeted at PC enthusiasts. It will be sold both as a bare drive, and with a PCI-Express 2.0 x4 add-on card, with an M.2 riser.

We are at PC-133 SDRAM speeds for data storage. Nice!

That m2 ssd not being screwed down bothers me a bit.

This is a decent performance bump. If priced right it could be a good choice.

Looks good except that random transfers are without changes for like 2 years now and it's actually most important for daily work. I doubt anyone is buying SSD to store large audio/video files. All others will barely see any difference between these SSD and anything on standard SATA.

New Samsung PCIe M.2 SM951 can read and write sequentially at 2,150MB/s and 1,550 MB/s on PCIe 3.0 x 4.

Plextor must do better.

Again if the price is right this could be better than Sammys offerings as not many need those speeds.

Now there's something I can use my M.2 32 Gb/s for! Impressive speeds..

I agree. Even the Sammy SM951 might not feel any faster that SATA 6GB/s, as its random reads and writes are around 130,000 and 85,00 IOPS. That's not shattering any records; my 850 Pro does 100,000 and 90,000 random IOPS. My M6e 256GB actually feels the same as my 850 Pro or 840 Pro. Nothing worse than an expensive "upgrade" that you can't feel "in the seat of your pants", even if the benchmarks look good on paper...

Perhaps if that is what someone is expecting.

I just want move up in capacity (have 128GB M4) and form (no wires). Any performance gains are just icing

Did you notice a difference with RAPID on?
