Intel SSD 750 PCIe SSD Review: NVMe for the Client
by Kristian Vättö on April 2, 2015 12:00 PM ESTFinal Words
For years Intel has been criticized for not caring about the client SSD space anymore. The X25-M and its different generations were all brilliant drives and essentially defined the standards for a good client SSD, but since then none of Intel's client SSDs have had the same "wow" effect. That's not to say that Intel's later client SSDs have been inferior, it's just that they haven't really had any competitive advantage over the other drives on the market. It's no secret that Intel changed its SSD strategy to focus on the enterprise segment and frankly it still makes a lot of sense because the profits are more lucrative and enterprise has a lot more room for innovation as the customers value more than just rock-bottom pricing.
With the release of the SSD 750, it's safe to say that any argument of Intel not caring about the client market is now invalid. Intel does care, but rather than bringing products with new complex technologies to the market at a very early stage, Intel wants to ensure that the market is ready and there's industry wide support for the product. After all, NVMe requires BIOS support and that support has only been present for a few months now, making it logical not to release the SSD 750 any sooner.
Given the enterprise background of the SSD 750, it's more optimized for consistency than raw peak performance. The SM951, on the other hand, is a more generic client drive that concentrates on peak performance to improve performance under typical client workloads. That's visible in our benchmarks because the only test where the SSD 750 is able to beat the SM951 is The Destoyer trace, which illustrates a very IO intensive workload that only applies to power users and professionals. It makes sense for Intel to focus on that very specific target group because those are the people who are willing to pay premium for higher storage performance.
With that said, I'm not sure if I fully agree with Intel's heavy random IO focus. The sequential performance isn't bad, but I think the SSD 750 as it stands today is a bit unbalanced and could use some improvements to sequential performance even if it came at the cost of random performance.
| Price Comparison (4/2/2015) | |||||

| Samsung SM951 | $120 | $239 | - | $459 | - |
RamCity actually just got its first batch of SM951s this week, so I've included it in the table for comparison (note that the prices on RamCity's website are in AUD, so I've translated them into USD and also subtracted the 10% tax that is only applicable to Australian orders). The SSD 750 is fairly competitive in price, although obviously you have to fork out more money than you would for a similar capacity SATA drive. Nevertheless, going under a dollar per gigabyte is very reasonable given the performance and full power loss protection that you get with the SSD 750.
All in all, the SSD 750 is definitely a product I recommend as it's the fastest drive for IO intensive workloads by a large margin. I can't say it's perfect and for slightly lighter IO workloads the SM951 wins my recommendation due to its more client-oriented design, but the SSD 750 is really a no compromise product that is aimed for a relatively small high-end niche, and honestly it's the only considerable option in its niche. If your IO workload needs the storage performance of tomorrow, Intel and the SSD 750 have you covered today.

I just recieved my 750 yesterday and soon found myself slightly bummed out by the lacking NVMe BIOS-support in my ASUS P8Z77-V motherboard. I managed to get the drive working (albeit non-bootable) by placing it in the black PCIe 2.0 slot of the mainboard, but this is hardly a long term solution. I posted a question to the https://pcdiy.asus.com/ website regarding possible future support for these motherboards and this morning they had publised a poll to check the interest for BIOS/UEFI-support for NVMe's. Please vote here if you (like me) would like to see this implemented! https://pcdiy.asus.com/2015/04/asus-nvme-support-p...Elchi - Wednesday, April 15, 2015 - link
If you are a happy owner of an older ASUS MB (z77, x79, z87) please vote for NVme support !http://pcdiy.asus.com/2015/04/asus-nvme-support-po...

Lets say I had an Intel 5520 Chipset based computer that has multiple PCIe 2.0 Slots. I would be able to get almost the maximum read performance (Since PCIe 2.0 is 500MB/s per 1X, 4X = 2000MB/s, which is exciting on an older computer. I am curious as to if this would be a bootable solution on my desktop though. With 12 Cores and 24 Threads, this computer is far from under-powered, and it would be nice to breath life into this machine, but the BIOS would have no NVMe support that I can think of. I know it has Intel SSD support, but this is from a different era. I wish someone could confirm that this either will, or will not be bootable on non-MVMe mobo's. I am getting conflicting answers.vventurelli74 - Monday, May 4, 2015 - link
Nevermind, finally found the requirements that this drive will not be bootable on on NVMe machines, whats more is even using it as a 'secondary' drive requires UEFI apparently. My computer wouldn't be able to use this card at all? That would suck.xyvyx2 - Friday, May 8, 2015 - link
Great review!Kristian, any chance you have two of these drives in the same machine & you could test RAID0 performance? I'm running into some slow read performance when using two Samsung PCIe drives in a Dell server w/ a RAID1 or RAID0 config. It's not like regular bottlenecking where you hit a performance cap, but where transfer rate drops down to ~ 1/5th the speed at a lower xfer rate.
I thought this was just a Storage Spaces problem, but the same holds true w/ regular windows software raid. I got up to about 4,200 MB/sec, then it tanked. I then ran two simultaneous ATTO tests on two of the drives and they both behaved normally & peaked at 2,700 MB/sec... so I don't think I'm hitting a PCIe bus limitation... I think it's all software.
I posted more detail on Technet here:

How does the pcie card perform on a system without nvme?
