SoftRAID upgrades to 3.6.7
SoftRAID has upgraded its Mac RAID software to 3.6.7, in response to compatibility problems with Leopard. The main feature of the upgrade is a new driver mechanism that stores two copies of the RAID header information. Leopard users on Intel-based Macs were experiencing occasional RAID header corruption, which led to SoftRAID engineers having to recover the volumes. The new update stores a backup copy of the header as a fallback when the software recognizes the primary has become corrupted. The corruption was occurring at a ratio of 1 in 10 million header write cycles. The update is free to version 3 owners and costs $130 for a downloaded version ($150 retail).
The update also adds improved compatibility with Leopard and Apple's professional applications such as FinalCut Pro and Aperture, and improves reliability on startup volumes for both PPC- and Intel-based Macs. SoftRAID runs on any version of MAC OS X 10.4 or higher, and allows users to run RAID volumes across multiple input/output channels (SATA, FireWire, USB, Fibre, etc.).
The software package can set up RAIDs on different sized volumes and run multiple RAID volumes on the same disks. It has user notification of errors and automatically rebuilds out-of synch mirror volumes. It supports RAID 1 (mirror) and 0 (stripe) volumes and can boot OS X on mirrored volumes.
