SuperTalent USB 3.0 Express Dram Disk Review – Simplicity With Ultra High Performance


The funny thing about the speed of memory is cornering an exact number on performance is almost impossible, a GB/s transfer gained or lost can occur at anytime.  Super Talent specifications list their testing at over 5GB/s speeds where we get 10GB/s from the same software.  Our having 32GB of memory available did allow a larger Dram Disk though which might have increased transfer speeds.

We had originally discounted the validity of ATTO as the pattern we were seeing just didn’t seem right.  The numbers were all over the place:


Next up, we tried things out with Quick Bench and the things seemed a bit more stable:

QuickBench 4k

We couldn’t resist the opportunity to put the Dram Disk through its paces in PCMark Vantage as well.  To say that these are the best results we ever obtained is an understatement.

In the end, the only method of analysis we could rely on for performance testing was moving a 1080P HD 2.5GB movie from one spot on the Dram Disk to another; we were wrong.  The movie copied and transferred so fast that the normal copying screen never even appeared; it had to be complete in 10th’s of a second.  It was at this point that we realized that the 32GB version  would have been much more effective for larger file transfer than our 8GB drive.

    If I can get half the performance from DRAM disk that the editor is claiming on my aging 2007 HP Pavilion notebook that has win8 pro then I’m in !

    to me it looks like just another flash drive with ramdisk software…

    Another shitty review from a shitty site.

    Hardware such as this has certain requirements. You need to have enough ram (16gb preferably) if you want a large “dram disk” such as 8gb or 32gb if you want 16gb. Two when you plug it in, it starts synchronizing what you have stored, so when you want to use it a minute later, it will already be saved in the ram, so they appear impossibly fast. Three, it only works on windows based computers and *appears* to require the included software to be installed on any computer you use it to function.

    So I need to have enough free system RAM to make a RAM disk to hold the files, AND USB 3.0, AND Windows, AND the special software–all just to enable a background file copy? What’s the use since I can’t really do anything with the portable flash disk until the background sync from RAM is finished (which still happens at the same speed as a standard USB 3.0 flash key)?

      The implication is that the DRAM lives on the pendrive but it does not (and cannot at that price). Ultimately it is only partially faster than a regular thumbdrive. Misleading marketing.

        Perhaps you missed these statements…

        “that uses PC memory to significantly improve performance”

        “Using memory, most commonly refered to as ram disks, to improve system performance is not new by any means, however, lack of simplicity has kept this from becoming popular.”

    What a terribly misleading product. As Jon points out (and the spec sheet backs up), this is merely a standard USB drive. All you are doing is “pre-copying” the file to RAM for later writing onto Flash. Eh? What’s the point? Now, if Supertalent put a 8GB of RAM on the thumb drive and used a battery backup to keep the RAM alive…then it could do what the article implies. But otherwise it’s just a bit of faking out the user. Ridiculous.

    What is the source for the 2.5GB or larger movie transfer? Sounds like it already in memory. If on disk/SSD/flash then you could not get sub 1 second transfer speeds.
    I don’t think these transfer to RAM Disk amazing times mean much, since it is the end to end transfer times that matter. The transfer from RAM disk to SuperTalent flash stick MATTERS. Am I missing something here? You are just measuring RAM speed, which is usually 10GByte/sec. You are not measuring the NAND flash die transfer speed.

      You are right. The transfer is done in the new RAM drive from one spot to another in order to demonstrate (or at least try) the speeds achieved while using that drive. The flash drive was obviously too small and we think that using a larger data file might be able to yield numbers. The benefit of this drive is specifically geared towards those that work in media intensive data environments where manipulating the media benefits from such.

    looks like this is marketed towards a very specific segment of customers, and not the general public, despite what it may visually appear to be.

    Interesting drive. Now you’ve got me wanting yet another cool device!

    Once installed how long does it take to initiate the next time you plug it in? How long does it take to properly disconnect the drive? Does the Dram space vanish on PC shutdown and have to be reloaded the next time the device is plugged in?

    So what’s the real transfer speed of the pendrive? (not the RAM)..

    Will this work on Win8 ?

    I have
    an ASUS Zen Ultrabook i7 with 4GB on board RAM with USB3 (windows7). When away
    from the office I am frequently running 3D software packages such as 3D Rhino,
    which are RAM hungry at times. To speed things up significantly would the USB
    3.0 Express Dram?Disk
    be of any benefit to me and if so what size (as I only have 4Gb on board and there is some sort of ratio which I don’t understand either) – when rhino is open I have 40% left – work files are usually in the region of 250-500mb. Is the work files that I would be synchronizing?
    any feedback would be appreciated

    This USB drive is a waste of money. I bought it thinking I would be able to use it as an external volatile RAM disk. I wanted to put a 2 gigabyte file on the USB drive so I could access it very fast. My laptop only has 2 gigabyte memory. The best I could get was 764mb of my own laptop’s memory, and I could have done that with free software from the net anyway.
