Introducing the MB994IPO-3SB, a full metal dual bay 2.5" SATA/SAS hard drive / SSD mobile rack backplane designed with a Slim Optical Disk Drive (ODD) slot for use in a single 5.25" device bay. It's a perfect device designed for small form factor system or server such as: IPC, HTPC, NAS, Home Servers and All-In-One computers. Dual 4-pin power connectors are used to ensure secured and consistent power supply to both drives and ODD, whether they are low power consumption 2.5" SATA SSD's or power hungry 15000 RPM 2.5" SAS drives. Also included is a single 40mm cooling fan with on & off switch to assist the drives running at their optimal temperatures, in even the most intense applications. Versatility is the Key The MB994IPO-3SB separates itself from the rest of the MB994 series by the unique Slim Optical Disk Drive slot that is available. The Slim ODD slot uses our EZ-ODD Tray made of full metal, and is easily removable by use of the provided key or via a side latch. This allows system integrators more freedom to better meet their potential client's needs. The MB994IPO-3SB utilizes our EZ Slide Mini Trays, making drive interchangeability and maintenance completely hassle free. The trays are built using full metal so that they are durable for many lifetimes, while will not weigh you down when transporting your data from system to system. Also featuring a full cage design, the added top drive cover provides added layer of protection while moving the drive. The trays are designed to accommodate 9.5mm, 12.5mm & 15mm drives, giving you excellent control of your 2.5" hot swap backplane. Fan control further allows the potential system to be accommodated properly depending on the hard drives used. If a SSD is used, fan can be left off and shut off the noise completely from the MB994IPO-3SB. Otherwise, the fan is a great asset to assist in cooling mission critical hard drives.
