More than a year ago I was rebuilding my home server, wanted to segregate the boot-system from the data, and do no less for shadow copies and swapfile. To that end, I picked up a Mushkin Chronos 60GB, thinking that I could use it for the latter items.
The boot/system files remain on a 120GB 840 EVO, but the Mushkin SSD just seemed like an unnecessary complication. So I've turned it into the caching SSD for a large HDD on a workstation.
I never really had a problem with it, but it was never deployed in a system where it had to be the fastest thing on the planet. I thought for sure that it benched better than the results shown here by another poster, but I really can't remember with any specificity. I only know that I wouldn't have purchased it if the spec sequential read and write rates weren't close to 500 MB/s
