Ultrabay 2000 hard drive VS intrenal main hard drive

[SaberX]

Will you get the same speed or proformance from a Ultrabay 2000 hard drive adapter with a drive in it as a main hard drive.
Both drives are say 5400rpm and same size.
What if you use the Ultrabay 200 adapter and put in a 7200 rpm drive.Will you see a diffrence in useing it?

the ultrabay conenction is IDE, so I dont think you'll see the same performance as an internal drive. However, I'd guess that it is faster than USB ...
