If you have 2.5 "disks (SSD or laptop HDD) - there are 4 seats on special brackets on the back side. If you have ordinary 3.5" drives, then you can put only 2 disks on the same brackets. But, thanks to the perforated case and shoulder arms, you can attach a few more drives both inside and outside the case. The case turned out to be very "creative". I liked it, although it is not without flaws.
