MyDigitalSSD OTG (On The Go) Pocket SuperSpeed USB 3.0 mSATA SSD Review (256GB)

AS SSD BENCHMARK VER 1.6

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Throughput is displayed on the left with IOPS on the right:

ANVIL STORAGE UTILITIES PROFESSIONAL (BETA)

You may not see this for long (and it’s definitely not common) but you get a freebee simply for reading!  Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility.  Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

For the most part, testing with incompressible data in Anvil confirms what we saw with AS SSD.  It also gives us an excellent opportunity to confirm its identification, as well as system identification, along with IOPS and disk access times.

REPORT ANALYSIS AND FINAL THOUGHTS

I typically don’t like to put products side by side because most people could never visually observe any differences from one SSD to another, and also, because SSD technology is such a massive step forward.  We are going to make an exception in this case, if only to identify the importance of understanding how specific memory can affect performance in a portable storage device.  Just before this review, we reported on the EDGE diskGO that is a similar product but uses asynchronous mlc memory in order to retain value.  The MyDigitalSSD OTG SSD, on the other hand, has a very similar price, yet uses Toshiba premium toggle mode memory.  Take a look at the difference testing highly incompressible data, the MyDigitalOTG on the left and the diskGO on the right:

MyDigitalSSD OTG vs EDGE diskGOAs you might imagine, it will take longer to transfer files using the EDGE, in comparison to the MyDigitalSSD OTG that we are reviewing today.  When comparing the two, we can identify that EDGE relied on the premium LSI SandForce controller and controlled pricing with the asynchronous memory, whereas MyDigitalSSD had better success with the mid-level Phison controller and premium Toshiba memory.

REPORT ANALYSIS AND FINAL THOUGHTS

Value, size and performance are the three things that make the MyDigitalSSD OTG SuperSpeed Pocket SSD such a great product.  It was only a matter of time before someone used the small size of the mSATA SSD to their advantage and we are now seeing the result in ultra small external SSDs.  Timing of this couldn’t be better as we are seeing UASP and SuperSpeed make a successful transition into the retail market, which gives us incredible speed in a very small for factor.

MyDigitalSSD OTG Pocket SSD Angled 2MyDigitalSSD is going one further by using just the right components in order to market the OTG (On The Go) as a value driven solution.  This brings the SSD in at 66¢/GB and the only way it could have been done was with the Phison controller, a controller by the way that seems to be enjoying much success around the internet.  MyDigitalSSD could have probably saved themselves a bit of money with ‘less premium’ memory offerings and we are glad they didn’t.  Our being able to transfer a 9GB Blu-ray movie in 24 seconds, as well as a HD movie in 3 seconds, is the result.

For value, performance and build size, we are awarding MyDigitalSSD with or Gold Seal.

  1. and is there a “SuperSpeed PCIE card that can be added to a system to allow these fantastic speeds???

  2. I am new to SSDs and so i have a question, which google couldnt really answer: How i can exactly determine if my motherboard is UASP compliant? (Z77A-G43 (MS-7758) Or didnt I understand UASP right? Is it enough to use Windows8 to get UASP compatible or do I need to use a special motherboard to get those sick max speeds?

    Thank you , great HP !

    • Don’t hang me if I am incorrect but UASP is integrated in Win 8…if the hardware supports it. All motherboards tat I know will identify it somehow and, in most cases, there will ne a SuperSpeed icon on the USB 3.0 ports that have SS. WE have several motherboards with and without and all newer boards contain it…and more importantly, identify it somewhere in the literature or on the board.

      Hope this helps.

  3. Can I swap in any msata drive or is the controller locked to mydigitalssd? Thinking a good home for a 1TB ego 😉

  4. I bought one after reading this review, only got 132 mb/s seq read 250mb/s write, 15mb/s 4k read and 27mb/s write. Then i try it on my imac, it’s still not as good as the result from this review, feeling disappointed. My firmware version is S8FM07.7.

    • Those readings are definitely questionable. Unfortunately, we have no way of determining if it is the drive or your system that might be causing the questionable speeds.

      • Thanks for reply. I check their website, they have the same performance on usb3.0 port without uasp support. With uasp support, they seems have the same sequence speed in this review. However, their 4k result is slightly higher than mine, 18m/s read/38m/s write, which is still significantly lower than the result in this review.

      • UASP support is the key here.

  5. Does it work with an android device with the otg?

  6. Can it work with ANDROID ?

    If it can use USB 3.0 B connector to USB 3.0 B connector and plug in to the SAMSUNG Note 3 – it would be perfect for on-the-go storage and reading of Video and Data files via the SAMSUNG Note 3.

  7. I recently purchased this drive based on this review and others. The drive performs incredibly well. I am running Windows 8.1 Enterprise Windows To Go from it and it is faster than my internal SSD! I have one concern – When booted from Win 8.1 on the OTG drive, windows sees the drive as a traditional HDD and not an SSD. I assume this means that it is not being managed correctly (ie TRIM, etc). Should I be concerned? Is there a way to set windows up so that it is aware that it is running from an SSD? Can I run TRIM manually on the drive even though the OS thinks it’s a hard drive?

    Thanks!

  8. I purchased the MyDigitalSSD 256GB to use as an external back-up on my MacMini OSX 10.9, but Time Machine would not use it to back me up. Failed. Help, I do not want to boot anything, or migrate to a faster Mac, I just want to use this handy storage as an external back up. So I dragged and dropped all my docs, pictures, desktop items over to it. It is busy copying them. Is a manual backup the way to go?

  9. Bought SSD OTG device formatted as FAT. Can i reformat this to NTFS? What will the problem in the future if I do this?

  10. I only experienced 1.95MB/sec and 2.29MB/sec transfer copy from NTFS . I cannot paste a screenshot as a proof here to show as compared with the advertised speed of 10x faster
