I recently looked at SSDs for a project I'm working on. By far, the biggest performance impact is in using PCIe rather than SATA interfaces. (The performance boost also may rely on M.2 and/or NVMe; because I don't have a PCIe controller on the system I was working on, I didn't look into it further). An example: Samsung 850 Pro, reputedly one of the fastest SATA SSD drives (SATA 3, 2.5", AHCI): * Sequential read/write: 550/520 MB/s * 4K random read: 100K IOPS Samsung 950 Pro (PCIe 3.0 x4, M.2, NVMe): * Sequential read/write: 2,500/1,500 MB/s * 4K random read: 300K IOPS Source: http://www.anandtech.com/show/9702/samsung-950-pro-ssd-review-256gb-512gb http://www.anandtech.com/show/9702/samsung-950-pro-ssd-revie...

Yeah, you get a PCIe 3.0 SSD standard with the newer MacBook Pro's and it is awesome [1, 2]. I have totally forgotten about slow disk access.

I use the 850 Pro, and it is very fast, but has many issues with Windows 7 (which is what I have).

  Care to elaborate? I was about to pick one up but now you have me hesitating.

    I'm unaware of negative interactions with Win7 and the 850 Pro, having used one in my Win7 desktop for over a year at this point. I can't immediately find anything but one-off reports online that don't line up with each other, either - maybe they're thinking of the 840 line?

      Sorry, that was a typo, I have a 950 pro, and Windows 7 doesn't include an m.2 driver, which causes constant problems with booting and starting up after crashes. The 850 and 840 are both great drives.

I asked about it on Digital Ocean User Voice https://digitalocean.uservoice.com/forums/136585-digitalocean/suggestions/16344982-provide-nvme-backed-storage https://digitalocean.uservoice.com/forums/136585-digitalocea... and also the Linode forum https://forum.linode.com/viewtopic.php?f=7&t=14058&hilit=NVMe https://forum.linode.com/viewtopic.php?f=7&t=14058&hilit=NVM... So far out of the whole internet, there was no response, except for one guys saying it was really silly, but he also said that SSDs were really silly. So as usual it seems I am wasting my breath trying to interact with people.

The article acknowledges the availability of NVMe, but the price per unit of storage is far higher than for enterprise SATA SSDs. Cost matters, especially when you're buying thousands of units.
