Compare Sata and Ide Disk Drive?

SATA (Serial Advance Technology Attachment) is has faster data transfer than old parellel interface. It also hot swappable and basically thinner cable. I guess all the PC out in the market today are already in SATA.,not unless you are buying a second hand.

To answer your first question; with SATA you have SATA I (1) and SATA II(2), which have maximum theoretical transfer rates of 150Mb/sec and 300MB/sec respectively. With IDE drives you have Ultra ATA100 and Ultra ATA133, which are 100Mb/sec and 133Mb/sec respectively. As to your second question; SATA,specifically SATA II(2), would be my choice. SATA is the newer standard so it is somewhat future proof. Also it is theoretically faster than Ultra ATA which is the IDE standard. Lastly there are a lot more SATA drives available than IDE. One note, before you buy a hard drive make sure that the computer that you have/will have is compatible with the type of drive that you are looking at buying, and that your computer has an available connector and space for an additional drive if this is going to be a second hard drive. I am currently using both SATA and IDE drives in my desktop PC. I have a SATA II as my primary and an IDE as my second drive. One concern/drawback with SATA is that ( as the other poster mentioned) you may have to buy a data cable in addition to the drive. I also had to buy a power connector adapter for my PC, because I have an older computer. Emojboy if you have any additional questions, just respond to this post and I will try to get back to you ASAP.

SATA drives has much faster transfer speeds compared to IDE drives.

I use IDE! I haven't used sata as yet but I think that it's a good idea. For starters you don't have the huge 40 or higher 80 pin ribbon cable and so air flow is far better in your pc. Another good thing about sata is the fact that you can only insert it on the motherboard in one direction! There are some newer IDE cables that can only be inserted in one direction too but again, it's the airflow thing! If you have both IDE and SATA connectors on your motherboard then this is good, you can use the both of them and possibly install four or more hard drives into your system. I presently use my primary IDE for my one hard drive and I use the secondary IDE connector to attach my optical drive or cd rom drive. By keeping my hard drive as the master on the primary IDE it's perfomance is not slowed down by having another drive on the same cable, i.e. slave. Andrew

I think i would buy Sata for one or two reasons, to reduce the use of this big ribbon cable used with the IDE and again i think Sata hard drives are little bit faster that the normal IDE.But the down side about Sata is that you can only have the minimum of only a sigle drive on the same cable which means if you have have a booard with 4 Sata controllers you'll need 4 Sata cables where as you'll only need 2 cables with the normal IDE
