Plextor M6e PCIe
This AHCI PCIe drive impressed us when it first came out, but a year or two on, it’s certainly not worth the premium prices we found online. SSDs in general have dropped significantly in price, and like-priced PCIe drives now out-perform the M6e by a factor of 3. However, if you find it at a saner price than I did, it provides a nice 100MBps to 200MBps boost over the Samsung 850 EVO and Intel 530.
You want one
I can’t emphasize enough how much better your computer will run with a PCIe SSD on board. Grab a small-capacity model, run your operating system off of it, and flesh out your storage needs with mid-range SATA SSDs or hard drives. You’ll be glad you did.
Currently, the SM951 is top dog, with the Kingston HyperX Predator PCIe delivering just about the same real-world, large-file transfer performance. If you spot a bargain on the XP941, it will deliver a very happy experience as well. If you’re looking to leverage an existing SATA-only M.2 slot, then Samsung’s 850 EVO is currently your best bet.
