yeah, kingofcomputers, they are the same. There are two types of floppys, ones that work, and ones that don't (unless you have a scsi?!?!). Bottom line though, if the performance of your floppy drive means that much to you, then you probably can get away with using a p133 or something of that ilk. Other than saving drivers, bios', etc, there really is no need for them in real world computing. The only real reason that computers are still using them today, is because they are so damn cheap, which goes back to my original comment to the original poster. You are not going to be disappointed nor overwhelmed no matter what Floppy you buy, so just go on priceline.com, look for a brand you trust, and buy it. The difference in cost is negligible, and so is any performance difference.
