I still have four of them. I have two other converters. I have used them for lots of HDDs. I mean to use PATA HDDs on SATA connectors. But not the other way. Highpoint converters are more expensive than some others, actually a lot more expensive, but surely they are small and easy to use. I didn't buy them myself but a friend in Seoul gave me as "bonus" when I bought a used Highpoint 8-ch. SATA card from him.
About performance, I never suspected if there'd any difference between PATA drives connected to PATA vs. PATA drives connected to SATA using such converters (if the HDDs are exactly of the same model.)
