the main difference is speed, due to the bandwidth increase with pcie, compared to sata. other than that, they are the same. m6e is actually a m.2 pcie ssd mounted on a pcie adapter.
the rest of the differences imo are basically about price points, form factors and compatible mobo features. unless your mobo let you do so, one thing about m6e is that it cannot set as boot drive.
talking about m.2 slot implementations, m6e is pcie x2 (10gbps), a common implementation for m.2 pcie slots in the newest mobo's. the exception is asrock z97 extreme series, which includes an ultra m.2 slot (32gbps). with that you can run a pcie x4 ssd.
edit: oh i was wrong, only select models of asrock mobo's has ultra m.2 slot.
Is there any proof that shows this PCIE SSD cannot be use as boot drive?
Most of the review sites that use multiple storage drive for testing so there are no conclusion, except the Guru3D use this PCIE SSD solely as storage drive.
Even if it's not bootable, there are many tricks to make it bootable, if the Windows/Unix bootloader can recognize this drive.
My cheap mobo don't have extra space for this SSD, else i would really bought it
Kinda bored of current SATA based SSD cause its already saturated the SATA 6GBs bandwidth. And uh i dont want the SATA Express SSD because of the ugly cable (are we going back to IDE cable? the hell with it)
