Hi Augeas, thanks for the input. I don't necessarily mean running a RAID array, although I am doing that as well; I do have single disks that don't TRIM because they're attached to the RAID card. The controllers these days have garbage collection built-in, even without TRIM, but some of my drives have slowed somewhat, and as far as others are reporting, the way to fix it was to wipe with high values. It is not my area of expertise.

Would it be possible to add options to drive wiper to state what data should be used when wiping? I gather from another thread here that the data currently used is all zeros. From reading around other forums, this is supposed to be better for virtual disks. Random is supposed to be better from a confidential data overwrite perspective. Writing ones is apparently what the TRIM function does with SSDs. My interest is from the SSD side; I'm using SSDs that sit on a RAID controller and consequently TRIM doesn't work. It would be nice to have the option of TRIMming SSDs manually. Thanks.
