‘Hot’ rating: As fast as hardware RAID; modest memory/CPU load; great support

The latest version of the software that delivers RAID 1,1,4, 5 and 1+0 without your having to buy a RAID box, has been fitted out with a new RAID Engine that’s just as fast and reliable as dedicated hardware RAID controllers. …Very useful is the addition of support for SMART monitoring on USB and FireWire disks. …As far as I know, there’s no other app on the market that supports this sort of SMART monitoring, and it’s a boon to have it.
