Under Linux, we can monitor SSD wear fairly easily with smartmontools whether the drive is presented as a normal block device or a generic device (which happens when the drive has been hardware RAIDed by certain controllers such as the one on the IBM HS22).
How can we do the equivalent under Windows? Does anyone actually use smartmontools? Or are there other packages out there?
The problem is that SCSI Generic devices just don't show up in Windows. If the drives aren't RAIDed we can see them fine.
How I'd do it in Linux:
sles11-live:~ # lsscsi -g
[1:0:0:0] disk SMART USB-IBM 8989 /dev/sda /dev/sg0
[2:0:0:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg1
[2:0:1:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg2
[2:1:8:0] disk LSILOGIC Logical Volume 3000 /dev/sdb /dev/sg3
sles11-live:~ # smartctl -l ssd /dev/sg1
smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32.49-0.3-default] (local build)

You need a utility provided by your raid controller. For example, most HP raid controllers have a compatible utility for reading the smart info from drives connected to their controllers.
