Performance vs. Transfer Size

ATTO is a useful tool for quickly benchmarking performance across various transfer sizes. You can get the complete data set in Bench. Both read and write performance seem to scale nicely with the transfer size and the Neutron XT is equal to the competition.

    I think the SATA 3 SSD market is already saturated. Read/write speeds and IOPS are pretty much as good as they are going to get. The only thing left to do is increase capacity and reduce costs. Why not start releasing drives for the new SATA Express interface, or more M.2 form factor drives? Too small a Z97 market? I guess we'll have to wait another year or so.

    I personally vote for skipping m.2 altogether. Let's just move right on to the PCI-E drives.

    I think you mean let's skip the M.2 drives that use the (slower) SATA protocol, and move right on to the M.2 drives that use the (faster) PCI-E protocol.

    Right. I have a Samsung M.2 PCIE drive, and after finally getting it to boot on my H97 board (using a EFI boot manager partition on my SATA SSD to point to its windows installation) all I can tell you is 1100MB/sec is pretty insane. It loads BF4 maps so fast I'm always waiting on the server...

    So you want to lose a GPU?

    The protocol is called NVMe, a PCI-E drive doesn't mean much.

    Actually both the legacy AHCI and the new NVMe protocols can be used on a PCIe-attached drive. The consumer Plextor M6e and Samsung XP941 use AHCI for compatibility reasons, while the new Intel server drives use NVMe for better performance in server workloads.

    Every single controller house is working on a PCIe controller for SATA Express and M.2, but the development takes time.

    honest question, not trying to be snarky, but how has apple been shipping PCIe SSDs for almost two years and no one else is?
