Make sure that the drive is plugged into a SATA 6Gb/s port. Your Asus ASUS B75M-A only has one SATA 6Gb/s port. The other five ports are SATA 3Gb/s ports.

Samsung SM951 MXHPV256HDGL (AHCI) installed in on-board m.2 connector.



On-board connector is only x2 so could probably get better read & write speeds using one of my Lycom DT-120 m.2 PCIe 3.0 x4 adapters but these speeds are fine for this machine. The two GTX 660 graphics cards installed in this machine are running at x8 so adding the m.2 card to the spare PCIe connector would drop the second graphics card down to x4 speed, the cinebench fps are very good for this setup, marginally better than my GTX 970 in the same machine.


Just for the fun of it I decided to remove one of the GTX 660's and put the SM951 SSD on a Lycom adapter to show the difference between the motherboard x2 connector and using an x4 adapter. Not double but definitely better on both read and write speeds.

How did you reach 1400 in Write? Are you on a 512 GB?

Yes 512GB. I use the NVMeFamily hack from this board (creates HackrNVMeFamily-10_11_5.kext), although I had the same speeds with the third party 'macvidcards' driver.

Here are new results with 10.12.2 Beta (16C63a) using 2 Samsung 950 Pro 512Gb in Raid0. I've included results of different block sizes from 32k to 256k. I always wondered if there's a big different in speed, and the result is that there really isn't.

This is running on a Gigabyte H170 Gaming 3 with a i7 6700K and 64gigs of ram.

I get the same with my 950 Pro. They are amazing for sure.

I think the chipset also has something to do with it, seems to run faster on X99, I've uploaded new tests done today (Dec 11th) post #279

I got a custon Fusion Drive consisting of a Samsung sm951 AHCI 256gb m.2 drive + Seagate 1TB drive. I would get much higher scores if I'd separated the drives, but I appreciate the convenience of a Fusion Drive more. The speed is plenty enough

Maybe so, I run on z170, however. Running with a 6700k overclocked to modest 4.5GHz.
