MyDigitalSSD SMART 256GB mSATA SSD Review – Top Performance Unmatched Capacity Killer Price

SPECIFICATIONS

The MyDigitalSSD Smart Series mSATA SSD family is available in three capacities, 64, 128 and 256GB, the key points here being ‘now available‘ and the fact that this is the highest capacity of any mSATA SSD we know of to date. Performance is not listed, as of yet, but we are aware that this mSATA SSD contains the SF-2281 SATA 3 processor, which means that it is probably pushing speeds of 550MB/s read and 520MB/s write with around 85,000 IOPS at low 4k random write disk access.  Pricing is set at $99.99, $179.99 and $319.99 at Amazon and the Smart comes with a three year warranty.

What still amazes me is that this mSATA SSD, which may be arguably one of the fastest consumer storage mediums available today, is only 1/3 the size of a business card, is only slightly higher than a 25 cent piece, and weighs only 6-7 grams.

SMART MSATA SSD COMPONENTS

The MyDigitalSSD Smart Series SSD family is SATA 3 and powered by the LSI SandForce SF-2281 controller.  Statements made by both MyDigital SSD and ADATA, with respect to the SX300, label the NAND flash memory as being either synchronous or Toggle Mode premium, however, as we can see here, NAND identification is not as we would typically see.

All attempts to identify this memory, via the internet, met with no success and, thus far, there has been no return from either company but to say that it is premium memory.

There are four 64GB memory modules on the mSATA SSD which total the advertised 256GB capacity, although formatting brings that down to 238GB of available user capacity.  In the case of every other ‘SandForce Driven’ SSD on the market (other than this and ADATA XPG family), the capacity we would normally see is 240GB which means the user gets an additional 7% capacity at no price increase.  Actually, pricing on this SSD is significantly lower than the industry norm for mSATA SSDs at present.

  1. will this 256gb drive work for upgrading the Samsung series 9b 2012 13 inch model?

  2. “Up until recently, ATTO was the only benchmark created specifically for SSD testing and it uses incompressible data.” I think you mean AS SSD

  3. from a press release today, the actual ADATA XPG SX300 SSD (256GB) is being sold for MSRP $299 so I’m hoping there’s a $20 coupon or something coming from MyDigSSD…

  4. I dunno if links are allowed or not, but the press release for the other one (or I guess the same one) with the $299.99 price is here:

  5. great website! ill admit im a bit of a noob when it comes to SSDs. ive recently purchased a lenovo y580 and im looking at possibly upgrading the HD since it is definitely the bottleneck of the system (1tb 5400rpm).

    maybe you could clarify a few things for me, is there a large gap in performance between a msata and sata ssd drive? im considering buying the 64gb version of the mydigitalssd smart series based on your reviews (mostly for the OS and because I can still use the capacity of the 1tb HDD that came along with the y580). would the 64gb version perform similarly to the 256gb version you reviewed? does this sound like my best move or am i better off buying a regular ssd?

    • The question you ask is key in knowledge of SSDs and, for the most part, it’s answer can change drastically depending on the tasks you have in mind for its use.

      Simply, unless you have a specific task in mind that will put excessive stress on the SSD, there is nobody that can tell the difference from one SSD to another regardless of size or form factor and that is because most of the ‘typical’ performance upgrade comes from an SSDs disk access time, all being somewhere in the area of 0.01-0.02ms typically.

      The key question with that laptop will be whether the mSATA can be used independent of a caching solution or will always be a cached SSD.

      • thanks for your reply! okay, would i benefit more from
        1)using a 64gb msata as fully cached ssd.
        2)using a 128gb msata as a boot drive/main apps and the HDD as a storage drive for things such as music, videos, and random games

        i am also just considering replacing my hdd with a regular 2.5 ssd but lack of capacity has me concerned.

      • My personal choice would be the larger as a boot drive for OS and apps with secondary storage of the rest.

  6. no coupon! its overpriced as usually by mydigss

  7. FYI, the main reason we were able to release it 1st is because I have been spending the last 3 months convincing them to build it. 🙂

    • I’ve noticed that you can buy the “ADATA XPG SX300 ASX300S3-256GM-C mSATA 256GB ” for $249 at Newegg.com. While there may be some similarities between this product and the one that MyDigitalSSD is offering in this review, I expect there are probably some key differences (firmware, warranty, etc) as well that account for the $70 difference in price. As I’m new to the msata SSD scene, can someone help me understand what the differences might be in simple terms?

  8. hey guys. What type of configuration can you this SSD with a primary boot drive? I am asking because I am interested in purchasing a new Alienware M18x. When I am configuring my drive options there’s a 500GB 7,200 RPM + 32GB Super Cache mSATA SSD. I was thinking of swapping the 32gb to a higher gb mSATA SSD. Would a RAID 0 2 x 500GB 7,200 RPM (1TB) be faster than a 500GB 7,200 RPM + 32GB Cache mSATA? I am doing intense editing of HD files + long renders. I would like to understand the logic of this hybrid solutions vs. the more practical but pricier solutions. Any help would be greatly appreciated. Thanks

  9. Any news on when these might be available again. Everywhere I can find them listed for sale they say they are back-ordered 🙁

  10. I wanted to purchase this ssd for my asus ep121 slate but currently unavailible. I noticed your adata sx300 comparison, found the adata but the part number is as
    asx300s3-256gm-c with the c on the end not the b will this work? i am assuming the b was for beta and c for consumer if i am guessing right

  11. Hi, I noticed the power consumption on the mydigital smart series drives is much larger (3W) than the BP3 series (<0.9W), does this have a huge impact on laptop battery life? Also, does the 5.02 firmware have the same TRIM problems as the other brands that use the same sandorce firmware? Thanks

  12. Any luck on identification of the memory modules? Are these the same used as ADATA?
