A floppy disk is a soft magnetic disk used for storing a small amount of data. It also helps in transferring data from one PC to another. Floppy disks are slower to access than hard disks and have less storage capacity, but they are much less expensive.

a jumper diagram imprinted on the drive itself. For price and compatibility, I'd stick with IDE. With IDE, though, make sure the drive is UDMA. Most likely, your motherboard supports ATA-33, 66 or 100. So, you may want to get a drive that can pump that hard. Get a drive with a decent rotation speed. 5400 RPM drives are slow. 7200 RPM is better, and higher RPM drives even better. The really fast drives, though, may require a hard drive cooler, so unless you are willing to mess with that, get a drive with a good balance of speed and temperature. If speed is your biggest concern, go for the SCSI interface. Keep in mind that with SCSI you will have to purchase the additional hardware necessary for the SCSI bus. Also, get the largest drive you can afford. You’ll be surprised how fast you can fill up a hard drive, depending on what you do with your PC.

These drives are very inexpensive now, get a fast one: 40X or faster. Make sure it is ATAPI compatible IDE. Some drives look like IDE drives, although they really use a proprietary interface, such as that used on some older Creative multimedia kits. If you're buying new, you won't find this in the stores anymore, so don't worry. If you want more than a simple CD-ROM, get yourself a DVD player. These drives are not much more than a regular CD-ROM and are backward-compatible with CD-ROMS, so they serve all purposes. Then, with a good DVD software player like PowerDVD or WinDVD you can watch movies or use DVD software on your PC.

DVD ROM is an advanced format of read-only compact disc. It can store up to 17 GB of data, that's good enough to store a full-length movie. One of the best features of DVD ROM drives is that they are backward compatible with CD ROMs. This means that DVD ROM players can play old CD ROMs, CD-I disks, and video CDs, as well as new DVD-ROMs.

A combo drive is a combination of CD RW Drive and DVD ROM Drive. with a Combo drive you can read huge amounts of data on DVDs or enjoy movies. You can also access data from CDs and even rewrite on them.

Until some time ago, you had CD ROM drives that were only capable of reading CDs. That means the data once stored could not be changed or erased by the CD ROM drive. This limitation is now overcome by CD RW disk drives. RW in CD RW Disk Drive stands for Rewritable. With this technology the rewritable CDs can be treated just like a floppy disk or a hard disk, and data can be written once, or over and over again depending upon the kind of CD-Recordable media used.
