Kingwin’s Dual SATA Enclosure holds 2 SATA drives in various RAID configurations.
- Supports JBOD, RAID 0, RAID 1, Safe 33 and Safe 50 RAID functions
- USB 2.0 and eSATA ports
- No software installation required
- Temperature-controlled fa, LED activity/status lights
- Size: 223 x 110 x 85 mm – 8.78 x 4.33 x 3.35 inches
- Supports up to 2 TB total (Seagate up to 1.5 TB total)
- Includes external aluminum case, USB/eSATA cables, manual and external power supply
Removing four screws on the back opens the case:
One HD slot is on the PCB, the other rides inside the case with SATA power and data cables:
You can even use notebook size drives, although you’ll have to figure out how to secure them – nominally it’s for 3.5″ drives:
The various functions are set by jumpers located at the rear of the unit:
There is a small Setup button that must be pushed to recognize the drives when installed – if you don’t push it, the LEDs will blink RED and the drives will not be seen by the OS:
The rear shows the ON/OFF, power port, USB, eSATA and cooling fan:
Kingwin’s Big Drive ships with a Manual (Don’t lose this!), external power source and plugs, USB and eSATA cables, screws and jumpers:
The manual is clear enough in what’s involved in setting up the enclosure for its various RAID functions. I developed a table to show what can be achieved with each setting – the “Virtual Drive” is what you’ll see in your OS; note the I used two different size drives to show what would happen in each case:
Drive 1 Size
Drive 2 Size
Virtual Drive Size
|Big Span||120||240||360||Virtual HD sum of two HDs|
|Normal||120||240||NA||Each HD is seen by itself|
|RAID 0||120||240||360||Virtual HD sum of two HDs – fastest access|
|RAID 1 – Safest||120||240||120||Virtual HD smallest of two HDs, all data written equally to each HD|
|Safe 33||120||240||One 40 Safe HD, One 280 Big HD||Each HD has 40 Safe, 280 across 2 HDs|
|Safe 50||120||240||One 60 Safe HD, One 240 Big HD||Each HD has 60 Safe, 240 across 2 HDs|
The most interesting settings are Safe 33 and Safe 50 – in these cases, each drive has a redundant sector in each drive with the remaining data over the two drives. This allows the user to allocate a portion in each drive as a secure backup, with the secure area equal to 1/3 or 1/2 of the smallest drive.Note that there is no software installation required – functions are set by jumpers on the PCB which is then recognized by the OS.
Kingwin’s Big Drive can give users some very interesting options for low cost hardware. I have a Dell Vostro 200 which is pretty much a basic box. Using Kingwin’s Big Drive, I can set up the Vostro 200 as a RAID 1 box for complete redundancy using an eSATA adapter to connect up to a SATA port. With a very nice array of functions to choose among, Kingwin’s Big Drive gives users lots of flexibility and a decent price.
Street price about $70.
