There are two major types of solid-state hard drives - multi-level cell (MLC) and single-level cell (SLC) drives. MLC drives can generally last for five to six years before failure; on the other hand, SLC drives may potentially be able to last decades.
The life expectancy for these drives is a few years. No computer device is meant to last forever.
240 hard drives, 20 floppy drives and 40 CD-ROM drives.
Some examples of data storage devices include: * Hard drives * CD, DVD, and Blu-Ray drives * Floppy drives * Zip drives * USB Flash drives * CompactFlash cards * SD cards * Tape drives
Magnets are not essential as part of the computing function itself, but many machines contain CD or similar drives, which are actuated by small motors. Which are magnetic in operation. And similarly for Hard drives, which use magnetic disks to store information. BUT -- But the imminent arrival of solid state drives, (Flash Memory of various sorts) may mean that there are no magnets in the computer. Excepting the loudspeaker which is likely to remain the magnetic type in the near future. [And excepting the transformers in the power supply.] P.S. Computer cooling fans also have magnets to be able to turn.
The normal computer user should always have a primary hard drive and a secondary hard drive. Hard Drive are not designed to last past roughly 7 years and more often then not, they die or become damaged within 5 years of purchase. The 2nd drive should be used as a "backup" to protect your valuable information. The 2nd drive can be "internal" or "external", but it is important to have a drive that saves your critical data/information.
You can get them pretty cheap nowadays. It ultimately depends on two factors. 1--Whether it is internal or external (Usually internal drives are cheaper than external ones) 2--Capacity in GB (the more gigabytes, the more money) I just bought a Western Digital Caviar Blue 320 GB internal hard drive for $28 including taxes as well as a Hitachi 500 GB external hard drive for $54 including taxes just to give you an idea. A good place to look is Newegg online or you can try any decent computer, electronics, or office store locally wherever you live like maybe Fry's Electronics, Office Depot or Staples.
Not necessarily. As a matter of fact, nowadays you can get what are called Solid State Hard Drives, which are quite different from the old school IDE hard drives and the current standard SATA hard drives. I don't know much about Solid State Hard Disk Drives but it is my understanding that they tend to last a lot longer than both IDE and SATA. A 60 GB Solid State hard drive will cost about the same as a 500 GB SATA drive, apparently because they last longer and are better all around.
Solid State memory is the memory use in flash drives and memory cards for cameras, cell phones, etc. Now, this technology is also being used right now in hard drives, even thought they still really expensive, the reading and writing speed are way better than the current hard drive technology, plus they last longer since they are microchips and don't use any moving parts. Eventually solid state hard drives are going to substitute the current mechanical hard drives that we now use.
Hard drives last for many years
Western Digital makes some really good external hard drives. They are fairly inexpensive. Another great company is Toshiba. There hard drives last for a very long time.

Yes; tape drives have error correction technology built in, and since tape cartridges have no moving parts they will typically last over a decade once written to and stored.
Cheap external hard drives are designed to last around 3 years, but the life span varies greatly on how often it is used, and how well it is taken care of. If the hard drive is used infrequently and is powered down when not in use, it can easily last 5+ years. If the hard drive is used frequently, kept in less than ideal conditions (wet, cold, hot, etc.) then it might not even last a year.
The utilities are the first one and the second one and the most important the last one !
The most common "drives", or storage devices, on a computer are hard drives and optical (CD/DVD/Blu-Ray) drives. Floppies were originally quite common, but have not been included on any new computers. USB-attached drives are common, but arguably not used on a single computer very often.

IDE drives only last for a linited number of years
