A portable SSD certainly sounds good, but the seriously fast speed the bring to the table comes with a relatively high retail price. Last week, we posted a review on the SanDisk Extreme 900 960GB Portable SSD and it cost $459.99 shipped. Today we are looking at the MyDigitalSSD Boost USB 3.1 Portable SSD that comes either as a diskless enclosure for $50 or a populated 1TB model for $440. The diskless version is a really interesting product as there aren't too many USB 3.1 Gen 2 enclosures on the market that allow you to run two mSATA III drives in RAID 0 for up to 830 MB/s sequential read and up to 730 MB/s sequential write speeds. Read on to see how this portable SSD performs!
