Best Practice: Watch the SoftRAID monitor
The SoftRAID Monitor is always watching for disk and volume errors.
When it sees one, it changes the color of the indicator in the menu
bar and puts up a dialog to get your attention. It also writes an
entry in the SoftRAID log file so you can go back lat...
Best Practice: Certify Disks Before Use

a pattern to every sector on the disk, reading the pattern
back, and checking it. It is only after certifying a disk with
SoftRAID before using it that you will know that the disk is t...
Best Practice: Replace predicted-to-fail disks
SoftRAID uses SMART data from each disk to determine if a disk is more
likely to fail. It interprets this SMART data based on the results of
a study performed by Google on consumer-grade disk drives. It checks
the number of reallocated sectors and the num...
Best Practice: Investigate all disk errors
Modern disks are very reliable. In our lab, we see most disks able to
handle over a billion read and write requests without encountering any
errors. This is the number of requests a typical disk gets in 3–5
years of use in a workstation or server.
Best Practice: Use a UPS with RAID 4 or RAID 5
All modern RAID 4 and RAID 5 systems use a cache to improve write
performance. This is true of both software RAID systems, like SoftRAID
and hardware RAID controllers. The write cache allows the RAID systems
to combine many small writes into a single larg...

Unlike most RAID controller...

SoftRAID Feature: Hours on Disk
_SoftRAID for Mac only_

been turned on (either with the platters spinning or when they are
stopped). We recommend that y...
