The Micron 9300 SSD is a 2½” U.2 (SFF-8639) product. Micron generally sells these to cloud providers and the server market. The new SSD replaces the old 9200 lineup while bumping up capacity and moving to U.2 (SFF-8639) exclusively.

The smaller M.2 is limited to 2TB but the Micron 9300 MTFDHAL15T3TDP-1AT1ZABYY reaches 15.36TB which is more expensive ($3,000) but the capacity is great. There is enough room for all of my games with room to spare.


Some high-end motherboards may offer 2 or more U.2 capable ports for supporting higher capacity SSD products. The typical gaming box with a M.2 slot can use one of these with a basic cable.

The typical ATX chassis has the ability to install U.2 SSD drives in the bays using some M2 screws to secure them into the hard disk bays. There are M.2 to U.2 cables which can connect the 9300 and immediately the machine will be able to install Windows as usual with a lot more room for games.

While expensive, the Micron 9300 is definitely a strong alternative to the sluggish performance of hard disks. Windows load up fast with the PCIe x4 based U.2 interface which delivers astounding read and write speeds.

The very low error rate is another excellent feature. Still using a backup solution is important as 15TB of SSD going south is not a good solution. Populating the NAS with some high-capacity 14TB disks can offer lots of backup choice when peace of mind is needed.

Micron markets the 9300 SSD to a wide range of corporate needs but we see it offering astronomical storage for games with rapid load times. The existing library of games now exceeds 4TB and it has been expanding as the collection grows. Hard disks are low cost which allows the entire collection to be downloaded and played on immediate demand.

In the U.2 format Micron competes with Intel primarily. Samsung is focused more with the M.2 format for personal computers. The cost of Samsung’s top SSD makes the Micron 9300 looks like a real bargain on a $/GB basis.

NewEgg offers this product on the US site but it is not offered in Canada. Often expensive products have to be imported which is par for the course.
