Article ordered and received very quickly. Article corresponds to what is advertised on the manufacturer's site. This is a hotswap 5.25 "bay that accepts internal hard drives 3.5 and 2.5 inches careful, the discs must be mounted on a carriage (1 supplied with the Bay), look if you have multiple disks consider buying SD11-TY35. The advantage is that it protects your minimal external drives. Otherwise molex 1 plug + 1 internal SATA. All solid air and lock the disk in place is reassuring. I recommend, especially as the system is not expensive: approx 38 full rack for 1 + 2 additional drawers (3 discs so).
