Introducing the ExpressCage MB741SP-B, a single-bay hot-swap enclosure for any 2.5" SATA/SAS hard drive or SSD for the 3.5" external bay (Floppy bay). With the rising popularity of small-form-factor (SFF) and portable computing systems, there is a need for convenient and secure access to data storage devices utilizing smaller bays. To answer this, the new ExpressTray drive caddy supports completely tool-less drive installation, without sacrificing security, with its enhanced screw-less drive gripping mechanism, stabilized drive insertion design, and single-piece latch. Furthermore, the strong metal chassis provides protection against bumps and shock, while the integrated air ventilation holes work to keep your drives running cool all day, even under heavy load.
