Intel 750 PCIe SSD Review (400GB)

The Intel 750 is the first NVMe SSD released into the consumer market. It offers users some pretty killer performance at a price point that is roughly twice that of top performing SATA SSDs. Back in April we were able to review the 1.2TB model. After seeing the results we were quite impressed, however, at over $1,000 the 1.2TB model does not completely fit the bill for most, unless you are an enthusiast or workstation user. This was quite evident when we kept hearing people ask about the 400GB model more often than the 1.2TB model, especially when compared to the SM951. For most gamers and storage nuts the 400GB model is far more within reach because of its lower price point and because of this we took it upon ourselves to attain the 400GB Intel 750 Series SSD for review. Now that it is in our hands, how does it compare?

Intel 750 400GB Main


The specs on the Intel 750 Series SSDs have not changed since our review of the 1.2TB model. They are available a 2.5″ 15mm and HHHL PCIe 3.0 x4 add-in card (AIC) form factors. The 2.5″ model doesn’t use your typical SATA or even a SATA express connector, however, it uses an SFF-8639 connector (now called U.2). This is troublesome for consumers as there is very little support for it at this time. Upcoming motherboards will be providing support for this connector though and some manufacturers have already started to ship M.2 to SFF-8639 adapters with their motherboards. Capacities are available in 400GB and 1.2TB. The 400GB model we are reviewing today goes for $399.99. If you want to step up to the 1.2TB model be prepared to dish out $1049.99.

In terms of speed the 400GB model is rated for up to 2,200MB/s read and 900MB/s write and thanks to NVMe it is rated for up to 430K/230K IOPS read/write.  The 1.2TB model’s performance is rated a bit higher at up to 2,400/1,200MB/s read/write and up to 440K/290K IOPS read/write.

Intel 750 Series 400GB Intel ToolboxIn terms of features it has TRIM, garbage collection, and S.M.A.R.T. support as well as power-loss protection. Also, the latest version of Intel Toolbox supports the Intel 750 and includes a bunch of useful tools and features such as SSD health monitoring, diagnostic scans, a firmware updater, a secure erase function, and a system tuner.

Finally, the endurance of the 400GB model is rated for up to a maximum of 127TB written (70GB per day) over the course of its 5-year limited warranty.


In our previous review our sample was delivered without the retail packaging, this time around we got the whole shebang. The packaging follows the typical color scheme as Intel’s CPUs so it is easy to distinguish. Capacity is listed on the front and the specs are on the back.

Inside we can see the SSD is secured in a plastic retainer and it comes with a driver disc and notice paper stating to go to Intel’s website for the latest drivers. It comes with the full-height PCIe bracket pre-installed with a half-height bracket included as an accessory.

As we can see the 400GB model looks identical to the 1.2TB model. Also, we can see the plate that is installed on the back of the PCB for aesthetic reasons, this is something that was not included on our previous review sample.

There are two Nichicon capacitors on the PCB to provide power in the event of an unexpected power-loss.

The Intel NVMe controller supports PCIe 3.0 x4 and is in compliance with NVMe 1.0 specs. The NAND is all Intel 20nm 128Gbit MLC. Strangely enough, the 400GB model has all NAND package spaces on the PCB occupied while the 1.2TB model did not. The 400GB model has 1024MB of Micron DDR3 operating at 1066MHz while the 1.2TB model has 2.5GB.

    Thanks very much for this review – especially for also covering boot times.
    Booting slower after post than expected and as samsung’s nvme drive is really a bit strange.
    Maybe it simply depends on the driver? Which driver did you use for booting
    test for the 750? Intel or Windows integrated one? Regarding
    performance after boot there are some differences in speed depending on
    the driver – maybe during boot too? Which driver was used for the
    samsung? Many thanks again!

    I’d be interested in seeing latency tests done between NVMe SSD connected directly to CPU PCIe Gen3 lanes vs PCH Gen3 lanes on the upcoming z170 chipset. Do you have any plans on testing it out or do you think the differences would be so minor it isn’t worth it?

    how about booting in non uefi systems like x58?

    Are their motherboards/adapters that could put 4 of these into a RAID 10 and see even further speed benefits? I’d like to make a database server with Windows Server 2012. Not sure where to start.

    I was reading this review and that of the Kingston HyperX Predator 480GB PCIe 2.0 M.2 SSD and I couldn’t fail to notice the huge difference between the writing endurance capabilities, while Intel 750 delivers 127TB writes (70GB/day), on the course of its 5 y warranty, the HyperX delivers a “staggering” 882TB writes (with an 1.7/day). I’m in the point of choosing on of them for my x99 system. My final objective would be: video/photo editing, gaming and last, but not least, running a couple of VMs (at least 5 VMs that are intended to simulate a Linux Lab and Exchange/AD environment). The main question is if this storage solution will last for at least 8-10 years if it only has a 70GB write/day?
    Thank you in advance for your advice and response Sean.

    Could you please provide a full Linux Kernel source build time ?
    such as “time makepkg” with ArchLinux x64_64

    As of 9/12/15 the Kingston Predator PciE ssd does not upgrade to windows 10 at all.

    If boot times are important I guess it would be better to use PCIe SSDs for storage only, while having the OS installed on a SATA SSD.

    You mention this SSD would be perfect for replacing a raid of SSDs used for media editing or virutal machine storage. Would it make a huge difference in terms of load times in certain games as well? Or would a high-end SATA SSD do the job just as good?

    Just bought this drive and not seeing the speeds shown in this article. is the speeds I am getting. Drive is plugged into a pcie3.0 x4 slot on a Dell T5600 workstation on a Windows 10 machine. Any pointers on what you needed to do to get the speeds mentioned in the article.

    I have done the following attempting to get the speeds you mentioned

    1. Installed latest intel nvme driver.
    2. Installed intel ssd toolbox and verified that drive is using pcie 3.0 x4 channel.
    3. Installed latest firmware.
    4. Reboot after the above.
    5. Switched to performance power plan.

    Speeds I get are shown in following image –

    Any pointers on things I could try?
