This dual 2.5in SATA hard drive enclosure provides a complete, hardware-based
external RAID storage solution for laptop or desktop computers.
Holds two 2.5in SATA (SATA, SATA II) hard drives and provides hardware-based RAID configurations including JBOD, Spanning
(BIG/Concatenated), RAID 0 (Fast), RAID 1 (Safe) and more - providing the
flexibility needed to create the storage solution that best fits your
application.
Versatile enclosure design allows for connecting to a host computer using either
USB or eSATA offering the speed
needed for your external storage to function seamlessly with your desktop or
laptop computer. Enclosure features an aluminum case, which helps to
protect against damage and also provides heat dissipation and a cooler working environment for
your installed hard drives.
Built-in Silicon Image SiI-5744 hardware RAID controller provides:
RAID 0 - Striping (FAST)
Set to RAID 0, splits the data and writes to both SATA hard drives at the same time,
moving data at double the speed of a single drive. RAID 0 combines both disks
into one volume...i.e. two 500GB drives are seen by the computer as a single 1 Terabyte drive!
RAID 1 - Mirroring (SAFE)
When set to RAID 1, all of your data is simultaneously written to both SATA
hard drives, creating a backup (or mirror) of your data on the 2nd drive. In the
event one hard drive fails, the enclosure will continue to function, reading and
writing from the good drive. Once a new hard drive is installed, the enclosure will
do an automatic background rebuild of the data to the new drive.
Spanning - Concatenation (BIG)
Spanning, like RAID 0 (striping) uses both disks as one volume. But unlike RAID 0 which writes a little data to each drive
in turn, spanning writes to one disk until it is full and then begins on the
next disk. Spanning is typically used if you have hard drives of different
capacities but would like to treat them as one volume.
JBOD - Just a Bunch of Drives (Individual Drives)
When set to JBOD, the enclosure configures your drives as two separate
drives. Each hard drive shows up separately to the Operating System.
Handy for users that need to use separate drives, but only want to use a single
eSATA or USB port to connect them.
SAFE33 and SAFE50
These two multi-RAID modes divide the external drives into two virtual storage areas,
one that focuses on data protection (RAID 1) and another area that provides increased capacity
(BIG mode). SAFE33 sets 33% to RAID 1 and 67% to BIG. SAFE50 sets
50% to RAID 1 and 50% to BIG. These two modes offer a balance between protection of critical data and maximization of space for non-critical data.
