Show me a link for such...and I'll believe it
I've been using SATA drives on my two computers for some time. The only reason I use my PATA drives is that they are good for storage and are problem-free.
I know that I've said that I don't use SATA drives for boot drives, I use the slower PATA drives for those because they are smaller in capacity. I see no point in installing XP on a 500GB partition...or even 250GB partition...as so many do.
I also tend to think the more drives used for storage, the less risk of catastrophic loss due to drive/disk failure.
