No tray = double the speedThe fact that the HDD does not need to be screwed to a tray makes the HDD installation much faster. A 5.25" bay is needed on the PC. SATA HDDs are supported SATA I/II/III.No fan = whisper silentThis mobile rack is made almost completely from aluminium. only the front and back panels are made of hard plastic. Aluminium is very stable. very light and on top of everything else. it dissipate heat perfectly. That is why no fan is needed in order to protect the HDDs. In case still wished. a 12V fan can be installed (not delivered in the package).No worries = lockedIn order that the HDD will stay protected at all times. a lock was added. In this way. no unauthorized person will be able to reach your data. An LED indicator provides information regarding HDD access and activity.
