What is the purpose of auxiliary storage devices

In enhancement to your difficult drive(s), you practically certainly will certainly want to install various other drives on your homebuilt computer. I"m calling these "auxiliary drives" to differentiate them from the tough drive.

You watching: What is the purpose of auxiliary storage devices

My meaning of auxiliary drives incorporate any type of drives or drive-like tools various other than the device drive or extra difficult drives or SSD drives. Basically, any type of tool that is not strictly required to develop a computer system, and also that can review, compose, and/or store data, would certainly be had in that meaning. A few of the more well-known examples are:

Optical Drives


In theory, optical drives encompass CD-ROM drives, CD-RW drives ("burners"), DVD-ROM drives, DVD+/-RW drives, and also Blu-Ray (BD-ROM) drives. They use lasers to check out and/or write data.

In practice, many optical drives obtainable this particular day combine many type of attributes and also the capability to review and create to different types of media including writeable CD"s and DVD"s. Top-of-the-line optical drives deserve to also play and write to Blu-ray disks. I doubt any kind of manufacturers even make ordinary CD drives anymore.

For fairly some time, optical drives were considered a requirement because they were the only practical method to install an operating device on a homeconstructed computer system. Operating units came on CD"s or DVD"s; so also if you never before supplied the optical drive aacquire, you required it that one time to install the OS.


Nowadays, that"s not so true anyeven more. Many operating units have the right to currently be derived as digital downloads and also "burned" to a USB flash drive for installation. Most software program is also obtainable by digital downpack. Consequently, many kind of computer systems everywhere the civilization have actually optical drives that literally have never been provided.

I"ve used optical drives enough times that although I no longer install them in the majority of computers I build, I carry out store a USB 3.x DVD drive handy. They still come in handy for listening to music CD"s, burning MP3 CD"s to listen to in the auto, and installing the significantly rare software application that can"t be acquired by digital downfill. Whether you want to install one, however, is as much as you. I no longer think about them important for most people"s computers. I simply think they"re nice to have.

On the dvery own side, I"ve found optical drives in general to be the least trusted of all computer hardware. In my experience, they frequently break down and also require replacement, also if they"re rarely offered. Replacing failed optical drives was among the the majority of frequent jobs I did once I was a functioning computer technician.

Card Readers


As optical drives decrease in popularity, card readers are taking their area -- fairly literally. Most interior card readers are sized to fit in a standard optical drive bay.

Although frequently referred to as "readers," all card readers have the right to both review and also write. Most are capable of analysis from and also creating to all popular flash media styles. Many also have USB ports. Some have FireWire ports or eSATA ports, and also a couple of can even read and create to SIM cards used in cellphones.

If you do digital photography or video or have actually any kind of other factor to relocate information between your computer and a card storage device, then a integrated card reader / writer will certainly make a really nice enhancement to your new COMPUTER. I actually take into consideration them much even more beneficial than an optical drive nowadays. If my homedeveloped computer system budget enabled me to buy just one or the other, I"d buy the card reader.

One crucial decision to make when buying a card reader is the kind of internal interchallenge it uses. Most use USB 3.0, many kind of use SATA, and also a couple of usage PCI-e. All 3 interdeals with have excellent speed, so which one you pick mostly depends on exactly how many headers or slots you have obtainable on your motherboard. If every one of your USB 3.0 headers will be provided by the computer"s front-panel USB ports, then you might want to pick SATA. If every one of your SATA ports will be provided by other drives, you have the right to use PCI-e.

Personally, my first alternative would certainly be a SATA card reader, assuming that I had a SATA header accessible, both for simplicity of installation and minimal resource sharing. But all three interfaces will provide excellent rate.

Legacy Drives

In this revision of the site, I"m demoting some kinds of drives to "legacy" status because virtually no one supplies them anymore. I"m retaining them largely for historic factors and also for those exceptionally few human being that might have a need for them.

Floppy Drives


The venerable floppy drive has actually seen much better days. Most brand-new computers do not even come with floppy drives any type of more, and many kind of new motherboards don"t even have headers for them anymore. They are officially and also unquestionably obsolete.

This is sort of sad to me bereason I remember the days as soon as floppy drives were the only drives a COMPUTER had. Tright here was no difficult drive. Generally tbelow were two floppy drives. One (the A: drive in DOS, later brought over into Windows) ran the operating device. The other (the B: drive) included whatever software application and information the user was working through.

Unless you execute data recoextremely or typically occupational through heritage data, I really can not think of a great reason to install a floppy drive nowadays.

Even I no much longer bother installing floppy drives, despite my sentipsychological attachment to them. Like myself, floppy drives are old-school; and I remember the days once they were cutting edge and also helpful. But that was a lengthy time back. I no much longer install them in any computer system I develop. I carry out, but, have actually a USB floppy drive that I use on those rare occasions once I must read data from an old floppy disk.

ZIP Drives


ZIP drives are magnetic drives whose disks deserve to host 100 MB, 250 MB, or 750 MB of data, depending on the drive model.

When CD-authors first came out, many kind of predicted the rapid death of ZIP drives. But the ZIP format defied the odds for years and also remained a famous removable storage medium. They were much more convenient to usage than early CD burners and had a much lower failure rate than optical drives (at least in my experience).

What inevitably did the ZIP drive in was not writeable CD"s, nor even writeable DVD"s. The ZIP format still had actually the upper hand over optical drives in terms of convenience and also device reliability. They remained a popular format with photographers, in particular, until rather newly.

What did in the ZIP drive was flash media, consisting of SD cards and USB memory sticks, which were convenient, inexpensive, fast, much easier to keep, and had actually even more storage capacity than ZIP disks. Flash media was additionally much even more convenient as a storage medium for digital camperiods because of its small size and also lack of relocating components.

Just like floppy drives, I have the right to think of no great factor to install a ZIP drive in your computer system unless you have a have to access information stored on ZIP disks.

Tape Drives

Strictly speaking, tape drives aren"t "legacy" devices. They"re still being produced and also boosted upon, and you can still buy a tape drive if you want one.

Many, many businesses still back up to tape. I offered tape for backup until a few years back, in fact, and I probably still have a tape drive in the basement somewhere.

Tape drives use the same interencounters as any other drives. Most interior tape drives usage SATA nowadays. External ones normally use USB 3.x, FireWire, or eSata.

The reason I"m demoting tape drives to heritage status is that for the overwhelming majority of this site"s targain audience, they"re no longer the ideal backup technique. Both the drives and also the tapes are exceptionally expensive and also the tapes have limited stays and must be reput often.

Most users are better off in the long run backing as much as a disaster-proof external tough drive and an digital organization. The local backup is handy bereason, well, it"s local; and also the online backup is for a doomsday scenario such as the neighborhood backup being stolen or damaged. I personally use ioSafe drives for neighborhood backup and also Backblaze for online backup. I additionally use GoodSync to move documents approximately the LAN and to synchronize my local records through cloud backup.

About the only great reason I deserve to think of for a lot of folks to install a tape drive would be if they use a digital camcorder that offers tape, and they know for a fact that a particular tape drive is able to read those tapes. Be certain about that, though. The truth that a tape tape-recorded by a camcorder will certainly fit in a tape drive doesn"t necessarily suppose the drive can read it.
