The CrystalDiskMark and ATTO benchmark tests below show the performance of the new BP3 mSATA SSD when connected to the mSATA slot inside a Lenovo IdeaPad Y480 notebook which supports SATA III (6GB/s) speeds. We spent a week running the drive through a serious of abuse tests — writing, reading, and deleting hundreds of GB worth of data over and over again in our lab while repeatedly benchmarking the drive and using it as both a secondary storage drive and a Windows boot drive. We decided to show the ATTO results here as well since both benchmarks often produce different results when determining the absolute fastest read speed of a solid state drive.

The key takeaway from these benchmark tests is that the BP3 performs VERY well … slightly faster than the published benchmarks on the MyDigitalSSD website.

Can You Replace Your Old Hard Drive With This?

We know most laptop owners don’t have notebooks with mSATA slots unless you happen to own an Ultrabook or a relatively new, well-equipped notebook. So, is it possible to use this 256GB mSATA SSD in your old laptop? The short answer is YES … but you might not want to.

First, if you want to replace the standard SATA hard drive in your laptop with a smaller mSATA SSD then you’ll need to purchase a mSATA-to-SATA adapter. However, at the time of this writing we were only able to locate mSATA-to-SATA adapters that use the SATA II specification … meaning the mSATA SSD would be limited to the 3GB/s bandwidth rather than speeds up to 6GB/s as it was designed.

In other words, using this mSATA SSD with a SATA adapter essentially drops the maximum speed of the drive to about 50% or normal speed. The CrystalDiskMark images below show the performance of the MyDigitalSSD BP3 SSD when used with a SATA adapter card. We tested it both as a primary boot drive (C drive) and as a secondary storage drive (D drive).

In both cases the BP3 SSD is faster than a cheap hard drive (something that would usually max out at a read speed between 80MB/s and 100MB/s) but you aren’t getting all the speed you’re paying for at this price point. The better solution is to stick to using the BP3 in notebook with a native mSATA slot or wait until you can find a mSATA-to-SATA adapter that supports 6GB/s speeds.


The bottom line regarding the BP3 mSATA SSD from MyDigitalSSD is that you now have a decent, relatively affordable option for high speed mSATA storage in a compatible Ultrabook or notebook. While this mSATA drive isn’t the absolute fastest SSD on the market, it is a blazingly fast SSD compared to most mSATA drives that come inside a brand new Ultrabook.

As we mentioned in the review, this drive doesn’t deliver the best “bang for your bucks” if you plan to use it as a direct replacement for a SATA SSD. The mSATA-to-SATA adapters we found were all limited to SATA II speeds. That said, it’s probably only a matter of time until adapters that support 6GB/s speeds will be available.

In short, if you’re looking for a mSATA SSD for your laptop then the MyDigitalSSD BP3 deserves to be at the top of your list.


  • A good solution for upgrading your Ultrabook.
  • A better solution for notebooks that have mSATA and SATA connections.
  • Fast, high capacity and relatively low price!


  • Only an “ideal” solution for laptops with native mSATA.
