MyDigitalSSD BOOST Conclusion

IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete. Please do not base any purchase solely on our conclusion, as it represents our product rating specifically for the product tested which may differ from future versions.

The MyDigitalDiscount BOOST 1TB SSD is a bold step forwards for external USB drives: its combination of two mSATA SSDs in RAID 0 combined with USB SuperSpeed+ support turned in the best sequential data transfer scores we’ve ever seen from a non-PCIE drive. However, the 10Gb/s connection isn’t without its drawbacks, which came in the form of much lower scores in random access and I/O operations per second. Below is a chart summarizing the performance of the BOOST 1TB drive on our benchmarks:

Test 5Gb/s 10Gb/s % Change
AS-SSD Read 87.2MB/s 34.1MB/s -61
AS-SSD Write 157.0MB/s 105.0MB/s -33
ATTO Read 458MB/s 687MB/s +50
ATTO Write 455MB/s 684MB/s +50
Crystal Diskmark Read 174.1MB/s 35.8MB/s -79
Crystal Diskmark Write 192.8MB/s 113.5MB/s -41
IOMeter 22044 iOPS 9619 iOPS -56
AIDA64 Read 401MB/s 629MB/s +57
AIDA64 Write 365MB/s 393MB/s +8
Vantage Overall 53144 50421 -5

As you can see, with a SuperSpeed+ connection, linear transfer performance increases dramatically, by 50% or more, in most benchmarks. On the other hand, tests that pile on queued, random transfers see a dramatic drop in performance (note that on the Crystal Diskmark and ATTO tests, the sequential performance still improved, although we’re only looking at the random performance here). This is probably due to the fact that the controllers on the Samsung SSDs are sitting “behind” an mSATA<->USB bridge chip. This poor random performance would concern me for an internal drive that the OS was installed on, but I think it’s no big deal for an external drive, which will most likely be used for backup and large data transfer tasks– and in these cases it will provide exceptional performance. If you’re a content creator, say, with a few hundred gigabytes of 4K video to move around, the BOOST is so much better than the next best solution that there’s really no choice at all.

While the BOOST is much more expensive than a terabyte-size ISB hard drive, it’s still not that expensive: its $262.12  price tag (MyDigitalDiscount Amazon) is very competitive with slower internal SATA SSDs, and anywhere from $60 to $100 less expensive than the Samsung T3 in 1TB capacity. Even if your computer only supports USB 3 Gen 1 at 5Gb/s, the BOOST offers the same performance as the Samsung for less money in this capacity.

MyDigitalDiscount trims costs by saving on retail packaging (as shown below), and not including any utility software or documentation. While I’m indifferent to most SSD “utility” software, a backup utility would have been nice, although it can be argued that both Windows 10 and Mac OS have sufficiently robust backup software built in.There’s also no documentation, but really: how many people will need to be told how to plug in an external USB drive?

At the end of the day, this drive impresses with its class-leading price-performance ratio. And if your desktop computer doesn’t have a USB SuperSpeed+ port, you can add one via an inexpensive PCI-E card. At $262.12 (MyDigitalDiscount Amazon), the MyDigitalSSD BOOST is your best choice today for an external SSD.
