NaBloPoMo – External Storage

Today we look atexternal storage devices.  With modern personal computers the storage is often internal but on many early desktops,  it was external to the CPU unit.  I am not showing a cassette recorder as I assume many know what they look like.

From top left going clockwise, we have a Wang Laptop SCSI drive,  5.25 inch drive at 360K, DEC RRD42-DA SCSI Compact Disk Reader at 780 MB,  DEC RD53 hard drive at 71 MB, HP 82902M, HP-IB interface 5.25 inch floppy drive at 270 KB, HP 82901M, HP-IB interface, dual 5.25 inch floppy drive at 270 KB each and a DEC RRD50 compact disk at 780MB.  Grand total of external memory = 922 MB,  not quite a GB.

The same set with an addition.  See it in front in red?  Yep an USB card reader with a SD card.  What size is the SD card?  Its 2 GB.  Over twice that of the rest of the drives.  Huge difference betwen the 1980s/early 1990s and today.


Some ancient interfaces.

    Ah, nice. I can almost smell them. I remember my first IBM Clone computer had a 5 meg and a 10 meg drive. It was crazy – how much storage I had! A few years earlier I had a Radio Shack Model III with a set of 1/2 height external 5 1/4 drives – double sided, double density 80 tracks – that gave me about 720k per disk and at the time, THAT was an insane amount of storage. Going the other way a few years I remember when my hard drive in my computer went bad and I went and bought an 80 MEG SCSI drive plus controller – for (cough) $850 – "top of the line" – and I admit, it was really fast but took me forever to pay off on credit. Meanwhile, yesterday (at work) I put a 750gb hard drive in an external USB case because "I had no other use for it".

    Storage is insane isn't it. My first PC had a 360K drive and a 1.44M drive. That was so much storage my sister-in-law would come over and place Kings Quest games so she din't have to swap as many diskettes, I late bought a SCSI hard drive at 30megs for about $300. Ouch. DEC made washing machine sized hard drives in the 1970s which were 3 phase and had only 5 megs.

    It's crazy how storage has changed and how large USB drives now are.

    It is indeed crazy. Did you see my post of the CORE memory?
