Samsung SM951-NVMe (256GB) PCIe SSD Review

 

PCIe and especially NVMe SSDs are without a doubt the hot topic in the SSD industry at the moment. There are still only a handful of drives on the retail market, but as we saw at Computex a few weeks ago, everyone is working closely on their PCIe...

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...

Samsung SM951 (512GB) PCIe SSD Review

 

The PCIe SSD revolution is upon us. So far nearly every controller vendor has shown off its PCIe SSD controller design and the latest news I've heard is that we'll be seeing a large number of PCIe SSDs from numerous manufacturers in the second half of...

If the SM951 was available today, I would have no reason not to give it our "Recommended by AnandTech" award. Being hands down the fastest client SSD on the market is enough justification for the award, but because the drive won't be shipping for...

Samsung SM951-NVMe RAID Review

 

The Samsung 950 Pro is available now and it's a hot seller, but the SM951-NVMe still packs a better value for shoppers looking to save. Today, we look at three Samsung PCIe solutions in both single-drive and RAID 0 configurations.

The Samsung SM951-NVMe should sell for less than the 950 Pro as resellers try to reduce inventory

The SM951-NVMe has a shorter warranty period and a lower TBW rating than the 950 Pro

The Samsung SM951-NVMe is available today from RamCity and currently costs less than the 950 Pro. We hope to see more separation in pricing, which would make the SM951-NVMe a better value. Right now, the prices are too similar to make us choose the...

Samsung SM951-NVMe Versus AHCI Versus SATA 850 Pro

 

Several readers commented on the lack of 2.5" SATA drives in our SM951 coverage. Comparing SATA to PCIe-based storage isn't apples-to-apples. I tend to make comparisons based on interface technology or price tag. Samsung's 850 Pro is a very fast 2.5"...

Samsung SM951 128GB And 256GB SSD Review

 

Samsung's SM951 is the hottest storage product on the market. Today we look at the two smaller versions, both of which still perform better than SATA.

Samsung SM951 PCIe SSD 512GB Review

 

If Samsung's claims are true then the lack of NVMe support shouldn't be too devastating for the SM951 as read speeds are said to reach 2150MB/s and 1500MB/s for writes, which should give the SM951 an advantage in write tests over the Intel SSD 750...

Samsung's SM951 is a better value than performance SATA SSDs when you consider it's twice as fast, not to mention that it's quicker and cheaper than Intel's NVMe-equipped SSD 750 1.2TB.

Availability is limited, but if you want one you can buy it. Drive ships with a three-year warranty vs. Intel's five-year coverage. Lack of NVMe might be a bummer but a new model is coming soon.

Samsung SM951 PCIe M.2 512GB SSD Review

 

Samsung introduced the SM951 last July during its annual SSD Global Summit in South Korea. Today we're running the drive through our benchmark suite to see if it lives up to the hype.

Highest performance available today, Ease of installation, Petite form factor

Price, Tricky Configuration when paired with older non-UEFI hardware, Early availability

The Samsung SM951 512GB is the fastest consumer SSD but buying one right now is difficult. In May that will change with higher availability. By July this level of performance could be common from a number of different products. Time will tell how the...
