3ware IDE RAID card + IDE -> SATA converters...good idea, or no?

[rocket357]

I recently had a 3ware 6410 IDE RAID card given to me, and I'd like to make use of it in a server at home. I have a few IDE drives laying around, but they're all smallish (between 20 GB and 120 GB), so I'm considering purchasing four new hard drives for it (the 6410 is a 4 port card).

Here's the question I have...I can purchase a few SATA -> IDE converters (like this one) and purchase 4 SATA drives to get considerably more storage space (speed isn't a concern, honestly, but they don't make 1TB+ IDE drives that I'm aware of)...anyone have enough experience with 3ware RAID cards to clue me in to whether or not this is a good idea?

Thanks!
