3QJ/3QJp Rack Enclosure

Thank you for purchasing CRU’s RAX 3QJ or 3QJp enclosure. RAX 3QJ and 
3QJp enclosures are rack-mountable storage enclosures that incorporate 
removable drive carriers that make it easy to use multiple hard drives in 
the same enclosure. RAX 3QJ and 3QJp enclosures provide four connection 

types that allow you the needed flexibility to connect to your host computer, 

including USB 3.0 which provides up to a 5 Gbps transfer rate. RAX 3QJp 
models also provide write protection to your hard drives with the simple 
toggle of a switch on the front bezel.

Features 

• 

Optional write protection on the RAX 3QJp enclosure prevents data 
from being overwritten or altered.

• 

TrayFree Models (RAX210) allow for easy insertion and removal of 

hard drives. Models with removable carriers (RAX211) enclose and 
protect hard drives when removed from the RAX enclosure.

•  eSATA, FireWire 800, USB 2.0, and USB 3.0 connections are provided 

for wide variety of connectivity.

• 

Specially designed drive and carrier interfaces are built to withstand 
tens of thousands of insertions.
