Q What are the specifications of the built-in fan?

         o    5400 RPM, 24,87 dB(A), 5,62 CFM or 9,55 m³/h

Q   Maximum drive capacity.

o    This product can handle SATA drives up to 3TB in capacity.

Q   What is the maximum transfer rate for SATA interface?

o    The SATA transfer rate will depend on the drive speed as well as which interface the controller card or motherboard uses.

o    The maximum transfer rate when using SATA 1.5Gbps (SATA I) is approximately 150 MB/sec.

o    The maximum transfer rate when using SATA 3Gbps (SATA II) is approximately 300 MB/sec.

o    The maximum transfer rate when using SATA 6Gbps (SATA III) is approximately 600MB/sec.

Q   Is this compatible with the new SATA 6Gbps (SATA III)?

o    Yes, because this device does not use any chipsets, the SATA connection from the drive is directly passed through to the motherboard/controller card. And since SATA 6Gbps saw no change to the physical connectors, it is compatible with SATA 3Gbps products where no chipsets are involved. Both drive and motherboard/controller card must support SATA 6Gbps.

Q   Can an aftermarket fan be used to replace the stock fan?

o    No. While some fans may fit, the unit was designed with our particular fan in mind. Using an aftermarket fan may void the product warranty and/or damage the device.

o    If a replacement fan is needed, please contact us for assistance.

Q   What is the difference between the long and the short version of the MB123 Series mobile rack?

o    The long version utilizes a 64-pin industrial connector to interface between the docking frame and the drive carrier. For hot swap environments like tape backup replacements, this is extremely beneficial because it saves the hard drive SATA connection from wear and tear. Inside the drive carrier the drive connects via standard SATA 7-pin data and 15-pin SATA power, and on the docking frame the unit interfaces with the motherboard/controller card via SATA 7-pin and 4-pin power connector. The long version also utilizes a 3-segment key lock with power option.

o    The short version has a shorter depth, but also interfaces differently with the docking frame. On the rear of the drive carrier, there is a small cut out for the drives direct connections to output. When it is inserted into the docking frame, the drives direct connection connects to the docking frame. The docking frame then has separate connections on the rear to interface between the motherboard/controller card using SATA 7-pin data and 4-pin power connector. The short version uses a 2-segment key lock, allowing the user to lock or unlock the drive.

-Long Version (MB123SK, MB123SK-B, MB123SK-S)

Q   What features does the key lock have?

o    The key lock on the long version is a 3 position lock.

o    Bottom position: Power off, tray unlocked.

o    Middle position: Power off, tray locked, but able to be disconnected from internal connection.

o    Top Position: Power on, tray locked in place.

-Short Version (MB123SK-1, MB123SK-1B, MB123SK-1S)

Q   What features does the key lock have?

o    The key lock on the short version is a 2 position lock, allowing the tray to be locked or unlocked.
