The SilverSATA II SR is a very slick-looking RAID (Redundant Array of Independent Disks) with a digital status window. It has a hardware RAID chip inside its enclosure; however, it’s only capable of RAID 0 (striping) and RAID 1 (mirroring) formatting.
The SilverSATA II SR sports two connections on the back, one eSATA port and one USB 2.0. The USB port is a welcome addition as it ensures that you can mount the SilverSATA II SR on computers lacking SATA connectors.
While the SilverSATA II SR wasn’t the fastest RAID we’ve recently tested, in our QuickBench tests it did perform very well in a 1GB file-copy and -duplication test. It also performed well in our Photoshop test.
The SilverSATA II SR incorporates the power supply in the enclosure. External power bricks are bulky, so that’s a plus.
When set to RAID 1 mode, the SilverSATA II SR can quickly copy hard drives. This is useful if you’re an IT manager and want to clone a boot drive, for example. If you install a drive alone in the enclosure and turn the unit on, it will consider that drive the master copy drive. If you then add a second drive, the SilverSATA II SR will automatically copy the data from the master to the new drive.
The SilverSATA II SR is not compatible with host adapters that use the Intel 31244 PCI-X-to-SATA controller chip. We had no issues using a Sonnet Tempo 4+4 card, apart from not being able to boot from the drive.
While WiebeTech doesn’t bundle a host card with the SilverSATA II SR, it does sell a PCI-X-compatible card, the TCS1-1, for only $60. That brings the total cost for the SilverSATA II 1TB SR and the host card to just under $1,102.

Macworld’s buying advice
WiebeTech’s SilverSATA II SR offers consistent performance and a stylistic edge. Its handy display screen shows the drive status and other useful information. The only knocks against the drive are the fan noise—which is noticeably louder than that of the competition—and price. If you’re looking for a quiet RAID, you should look elsewhere.
