It's been quite some time since our last SSD roundup and we hadn't seen much need for one until recently. SSD technology grew stale after saturating the SATA 6Gb/s bus, bringing mostly minor improvements in recent memory and making up for it with price...

Had Samsung's SM951 arrived before we reviewed the Intel SSD 750 Series 1.2TB I think our conclusion might have been a little less favorable for the Intel drive. The SSD 750 may tout NVMe support, but Samsung's SM951 is generally faster while being more...

This M.2 drive first saw the light of day at Samsung's annual shindig, the SSD Global Summit, which took place, in South Korea, last July. When it was first announced, the company claimed it would be the world's first NVMe SSD for the PC, but that idea...

Incredibly fast and surprisingly affordable for the speed, but the cutting edge tech means dicey compatibility and drivers that haven't fully...

The NVMe variant of the SM951 delivers faster speeds than its AHCI brother. This increase in performance comes at a cost, which is compatibility. If your system is compatible, however, you will not be disappointed. While it is expected to be available...

The best all around SSD on the market today with nearly every box checked. You can use it in several Ultrabooks and any 9-Series chipset desktop without hassle. This level of performance is a luxury so expect to pay accordingly.

Never being satisfied with the latest and greatest solid state drives, a wonder component a few years ago, Hardwareslave have been looking for something a little bit special. Step in PCIe SSD drives and for most the price isn't going to be achievable,...

Since the Samsung SM951 NVMe SSD is the first NVMe SSD I've ever had the opportunity to test, I wasn't really sure what kind of performance I'd be seeing. Having tested the Samsung SM951 AHCI, I assumed that there'd be some sort of performance...

All in all, the SSD 750 remains as the best option for very IO intensive workloads, but for a more typical enthusiast the SM951-NVMe provides better performance, although not substantially better than the AHCI version. If you need an SSD today, I wouldn't wait for the NVMe version because the availability is a mystery to all and you may end up waiting possibly months.
