For the longest time, I have been waiting for someone to take 2.5-inch external storage to new heights in terms of capacity. Late last year, we finally were able to reach 2TB in a 12.5mm z-height, and now with the Seagate-Samsung division, we have the M9T, the thinnest 2.5-inch 2TB hard drive at only 9.5mm.

From what I have read and researched, the M9T is an OEM-only design, so you will have to start harvesting drives if you want one for another purpose. Here today, we have one such storage solution carrying the M9T, the Seagate Backup Plus Fast.

For those that want this drive for its intended design, you will be happy to know it features a bus-powered USB 3.0 design, of course, and features 4TB capacity, which is the most density on the market in this portable form factor.

Compatibility of the Backup Plus Fast extends from Microsoft Windows XP through 8.1 and OS X 10.6+. MSRP for the 4TB capacity is set at $269.99 with a three-year warranty.

The PCB for the Backup Plus Fast appears to be a custom design from Seagate that utilizes the ASMedia 1090R and 1053 to combine the capacity of the drives so the host OS sees them as one unit.

Price/Performance had the Seagate at the top of our chart here thanks to the great sequential performance.

Build quality for the Seagate Backup Plus Fast is pretty good; the enclosure carries durable materials and certainly feels like it could take a drop if it were to happen, but I am slightly concerned that having the drives back-to-back in the enclosure could cause issues in the event of a drop on a hard surface.

Performance of the Seagate Backup Plus Fast is quite impressive, and it takes top honors in our charts as the quickest 2.5-inch external solution coming in at 244 MB/s read and 267 MB/s write. Price/Performance also put the drive at the top of our charts due to the overall performance of the unit.
