Toshiba MG11 Reviews

2 of 7 purchased DOA

By Robert
Rated 3 out of 5
Date: 2026-02-02

I bought 4 of these from BH and 3 from other reputable vendors. 2 of the 7 purchased have been dead on arrival. I like these drives because they run cooler than Seagate Exos and Western Digital Ultrastar (who've I've also had issues with). I guess better DOA than failure in service but I do wonder how the life will be. I have a few of the 20 TB version that are in NAS service successfully with no DOA for the last several months.

Is this the 512mb cache or 1024mb cache option?
