SATA IDE cable do most hard drives use toda.
EIDE
Typically EIDE cables connect to IDE Hard-drives and optical drives such as CD and DVD Drives. The cable connects between the motherboard of the computer and the hard-drive or optical drive. Normally most motherboards have two idea buses. You can have to drives per cable. So a total of 4 drives.
A ribbon cable is a cable with many wires running parallel to each other and are most commonly used inside computers connecting hard drives, cd drives and floppy drives. Older computers used them as external connections as well.
Most external hard drives come with the necessary USB cable. Most electronics retailers carry USB cables if you need to buy an extra.
Check the motherboard. You can connect two drives to a single parallel cable. Most traditional motherboards have two IDE sockets and you can run a maximum of four drives. (one cable per socket, two drives per cable) but you need to configure the drives with jumpers as "primary" and "slave". Many of the newer motherboards have a "SATA" (Serial ATA) socket or some combination of SATA and IDE but you'd have to use a SATA drive with a SATA cable to use the SATA socket.
Most hard drives these days come with 32 MB of memory, which is the most you'll see on consumer hard drives.
The most common problem with large hard drives is computer crashes.
Back up hard drives are recommended because most hard drives give no symptoms before failing catastrophically. Once they do, it is almost impossible to retrieve data.
There are a lot of varieties of the internal hard drives available from as low as 10 MB to 5 gb. In the present world the most preferred hard drives are 250 gb to 500gb.
Not really. The speed varies widely, even moment to moment, but they are not as fast as most internal hard drives.
There are many portable external hard drives which would fit into most standard size pockets.
Most computers have two internal connections for hard drives. You may also connect a third (external) hard drive via USB.
