Pros: Well documented Solid metal construction Works as expected High throughput in RAID 10

Overall Review: I put 4 16tb Ironwolf Pro NAS drives in this and configured it for RAID 10. This created a 32tb redundant array which when formatted ext4 came out just over 29tb. It worked immediately. The enclosure is about as small as it could be, all metal, and it has two fans with a slide switch to choose high speed, low speed, or off. At low speed my drives seem cool enough and the fans are not audible. The power is controlled by a simple slide switch which means it will power back up if it was on when power failed. A 12V external brick is included. RAID mode is selected using dipswitches, the settings are documented in English and Chinese. It makes sense. Be sure you read and do the part about resetting the unit after selecting RAID mode. I'm using this array with Channels DVR software on Kubuntu. I can record 6 simultaneous video streams with very low CPU utilization and zero dropped frames. It has slightly exceeded my expectations. I'd buy this again.

Pros: Works as described, with 4 Seagate 2TB hard drives in a RAID 0+1 array I've had not a single burp in about 6 months of usage. You use a series of button presses while watching the detailed front panel LEDs to select RAID mode. The enclosure idles down when no live computer is attached, then mounts gracefully at startup every time.

Cons: The drive installation involves a few plastic parts that are possibly fragile, but ten minutes later that will never matter again.

Overall Review: I'd buy another at a good price.

Pros: Very fast, quiet, attractive, looks good next to Mac Pro. Fantastic throughput using firewire 800. Time Machine copied 462gb in about 3 hours, woof!

Cons: Pre-formatted for MS Wormware

Overall Review: To use with a Mac, be sure to selectt the parent item, not the volume, in Disk Utility and first repartition the drive as HFS+ Journaled.

Pros: I've long preferred Seagate drives for their reliability and relatively quiet operation. I put 4 of these in my new Mac Pro, creating a RAID 0+1 array, it's yummylicious!

Cons: None

Pros: Slid right in to the memory cards on my 8-core 3GHz Mac Pro. just lovely!

Cons: None
