Gigs of Data? Where will you store it?

Data Storage

More commonly known as Mass storage

Make that mass data storage. Comes in two types: writeable and non-writeable.


Ok, consider this - you bought a program that came on a CD-ROM this is non-writeable media. It was written to at the software publishers factory. Done, can't add or change anything on that CD.

Writeable are: Hard drives, SSD (Solid State Drive), Floppies, Tapes, Flash, and Re-Writeable CD/DVDs.

So you have a large choice of devices whereto save your data to. Most are reliable for a long period of time.

The most non volatile is the CD/DVD. I have some CD's that were created in 1993, they are still readable, the programs are next to useless but I can copy them to a hard drive and they run.

The most common device is the mechanical hard drive. Hard drives continue to increase in capacity and speed. My first hard drive was 5 meg, it took me almost six months to fill it up.

SSD (Solid State Drive) are now becoming affordable for higher capacity. This is special type of memory that retains the data written to it after power has been removed. A SSD has no moving parts! It is all memory...

The SSD is rated at 1500+ G impact resistance, that means you would have to drop your computer from over 100 feet for the drive to be damaged. [This is some what a misnomer: dropping the actual device by itself will damage the case and the PCB inside, however the chips that make the SSD possible will be undamaged...]

Service Life: the SSD has a 1.5+ Million hour service life. Testing shows that it would take that long before the first failure. That is around 72 years...

There are three drawbacks to the SSD:

  • Write speed: (this has to do with the interface - IDE or SATA because the read speed is quite fast).
  • Size: Current affordable storage space is still over $1+ per GB, a 120 GB SSD will cost you over $120 for a high quality SSD.
  • Cost: While SSD's cost close to $1+ per GB, you can buy a 1 TB mechanical drive for the cost of a 120 GB SSD, if you can get away with a smaller drive in your computer you gain a few important benefits.

If you can afford it then a great replacement or upgrade for your computer desktop or laptop would be a SSD.

Update 02/15/14 - The SSD has officially passed the 1 Tetra Byte capacity, however unless you either have the money to burn or need it very badly these will set you back over $1500! A 500 GB SSD will cost you over $500!

Update 02/15/20 - As with all new technology the cost of a SSD is dropping, I bought a 500 GB for my new custom built computer[DIY] and it cost about 0.04 cents per GB USD.  Not bad considering my first 64GB SSD cost almost the same...

Next most common is the Floppy drive, the floppy is almost (not quite) obsolete because the Flash memory drive is taking its place. As a matter of fact some manufactures are not installing floppy drives in new systems, you get a CD/DVD rom drive to install software from, if you want a floppy drive you have to purchase it separately and normally it is a USB device.DVD RW drive

CD/DVD Rom Drives, these devices have increased in capacity since they were introduced and will continue to increase in capacity as the technology evolves. You can get a read only drive or you can get a read/write drive and make your own CD/DVD's.

Coming up fast is the Flash memory device, also know as pen drives, flash drives, etc. These are very compact and high capacity devices. Very convenient (in a way a security risk) they have a chip that allows the data written to ram and be retained with out power.

Tape devices are still around, although they are not as popular as flash devices, they offer long term high capacity storage. Tapes are good for about four years, the company I worked for had a requirement to retain tapes for 11 years, I had to check those tapes every year, if a tape is not stored properly it will degrade.

04/09/14 - A search of computer manufactures for computers with a floppy drive installed turns up zero computers that come with the floppy drive installed. Also a search for the drive alone turns up a few, all refurbished drives, none new. Of the few I found none had a warranty, consider that if you are buying a refurbished part. If you are in need of a floppy disk to create bootable media consider the virtual floppy drive/disk.
