1 Tb SD card!
May 19, 2019 08:36:19 #
Some day I may need such a large card but not now. I only use card that can hold enough images for 1 battery charge. Whenever the battery needs to be charged or changed I change the memory card as well.

Programming/display I/O was via an ASR33 teletype, 10 characters/second. The whole system took up a rack and probably weighed 100 lb.
Ahhhh, paper tape. Used it quite a bit.
Loved the teletypes! They'd go chuga-klank-whir-klank-tink-tonka-klank-, and print ONE character!
The guy(s) that invented those things must be in a nut house somewhere. An amazing mechanical rats nest inside.

When I travel I change cards at least once a day. When home I download the shots to my computer as soon as the shoot is over. So in most cases I can easily get by with a 16gb card even though I usually have two 32gb cards in my camera.

The paper tape was on the teletypo but for important stuff we used mylar tape. It was stronger than paper tape but if really stressed it would stretch instead of tearing and become useless that way.
Actually we took data on a magnetic tape. 7 track, which preceded 9 track, which preceded the phase encoded 9 track. If I recall correctly the 7 track tape wrote at 800 bits/inch. The advantage was that we could take the reel to the mainframe to do the final processing. I'm not sure that the mainframe even had a paper tape reader by that time. All that was back in the "punch a couple boxes of cards and schlep them 3 blocks to the computer building" days.
I also had an ASR28 teletype at home for the ham radio.

If and when they drop to the $100 range I will definitely get one as my backup card. Right now I use a 256 gig card and just leave it in the camera til it fills up while I use CF cards for daily downloads. I like the idea of having everything I've shot at my immediate disposal directly on my camera. I'm a wedding photographer and sometimes I want to show clients special images from a particular venues or locations. I also like to check exposure data for particular scenes or techniques I've employed in the past. It can be real handy in duplicating or improving on past performance.

What blows my mind is the Apollo’s guidance system putting a man on the moon had less memory of a commodore 64 PC. It accomplished this with only 2k of memory.

In 1961 (?) First National Bank of Arizona installed their first computer. It was put in the basement. They closed northbound Central Ave., dug up the street, sidewalk and the walls of the bank to get it in. Once installed it had glass walls on three sides so people could observe the 10–15 people working inside. It had its own power transformer, air conditioning and air filtration system. It was bi and it was big news at the time.

And if I remember correctly the communication error detection and correction method was to send the same data 3 times and see if it matched...

Current memory levels are needed for security, not calculations. Standalone computers can do with fairly small memories. It's getting online that ups the requirements by orders of magnitude.

Than and too many programmers write verbose code now.

No relying on just the CRC checksum?

Sandisk now has a 1 Tb SD card available. It's only $450 on their website!
With some of the super mega pixel cameras coming out, they might be a good thing to have?
I don't see needing one in my near future.

And when it gets dropped in the mud, or some such bad fate, you just trashed $450.

In 1976 I joined Digital Equipment Corporation (mini computer company). On a tour of the computer room, a consultant walked over to a cabinet that was about 3‘ x 3‘ x 6‘ tall. It contained four pull out bays with spinning storage disks. He said, “ each storage disk holds 2.5 MB of data, totaling 10 MBs. All of our system software and application software is housed on these disks. We also have quite a bit of space left over for data files. This 10 MB bank is all the storage you would EVER need.”
Guess they used jpegs then rather than RAW.

Why on earth would someone want to entrust so much data of any kind to a single little memory card, that is easily damaged or lost (and along with the camera it is in)?
Just because memory chip development is making such things possible does not mean that it makes sense. Same story with hard drive capacities.
