SanDisk A110 PCIe SSD: Armed With The New M.2 Edge Connector

Results: File Copy Performance

File Copy Performance with Microsoft Robocopy

Microsoft's Robocopy, a CLI directory replication command, gradually replaced the older xcopy. It's multi-threaded, has a ton of options, and generally outperforms vanilla Windows copy operations. Best of all, it's built right in to Redmond's operating system. Especially useful for network copy operations and backups, Robocopy doesn't stop to ask you one hundred questions while it copies over your music collection, either.

The reality of benchmarking file copy performance is that you need something fast to move data from and fast hardware to move it to. This is most important with SSDs. It doesn't matter if your drive can write sequentially at 500 MB/s if the source files are hosted on a USB 2.0-attached external hard drive. We're copying our test files from an Intel SSD DC S3700 to the drives in the chart below, taking source speed out of the equation.

There are 9065 files comprising the 16.2 GB payload. Some of the files are huge (up to 2 GB), while others are best described as tiny. On average, that's around 1.8 MB per file. The files are a mix of music, program, pictures, and random file types.

It's fair to say that this chart would look much different if we were copying from a hard drive to a SSD. Even if the disk drive's sequential throughput wasn't a bottleneck, it'd still choke on the smaller files.

The A110 blows the competition's doors off. Taking just 44 seconds to copy the payload translates to a scorching 378 MB/s. Although that raw figure doesn't necessarily sound impressive in light of the synthetic results we've generated, the way we're running this test, in addition to its composition, make the benchmark a challenge.

    Awesome new stuff. Can't wait to see if this drive actually uses the full potential of the M2, and if Samsung or OCZ can one-up them.

    Samsung actually has some pretty awesome M.2 PCIe action going on. We're trying to get our hands on everything, so stay tuned.

  • It will be nice to see vendors implement the NVMe connectors in the desktop mobo's, which in turn will redefine case design, as less storage space will be required for storage. I am aware that the initial intent is to direct these at the mobile market, but desktops can benefit as well.

    You'll really see NVMe take off on the desktop with the move towards SATA Express. A SSD on SATA Express will leverage NVMe and two PCIe Gen 3 lanes. Though some motherboards will (and already do) have M.2 connectors, M.2 really makes more sense in mobile applications. M.2 will only get traction on the desktop insofar as it will begin to replace mSATA. Tons of mainboards, especially smaller form factor products embrace mSATA, and moving to M.2 is a natural transition. However, M.2 drives are hard to find right now, and we really won't see a plethora of options until next year.

    I got M.2 toshiba ssd in my Sony Vaio Pro 13.. review that?

    and it should have samsung M.2 in some countries..

    I may no longer have motivation to upgrade my system based on CPU specs, but with DDR4, M.2, new restive storage based SSDs, and better chipset features I will still have enough reason to upgrade in a year or two.

    That's what I was thinking. SATA Express is going to be fast enough for now as I have used PCIe SSDs before (OCZ Revo based drive) and compared to my 520 its hard to notice a difference, especially since there are other bottlenecks stopping it from being able to utilize that bandwidth.

    This will be great for ultra portable systems though and ITX systems.

    Absolutely... just send it my way and consider it done.

    will there be RAID or SLI/CFX for PCIe based SSD's?
    I don't think so b/c it's already way above 6G limit.
