RAM: You’ve come a long way, baby!

My gaming desktop at home has 8 Gigabytes of RAM. If I had to use these 4KB modules instead of the two 4 GB sticks I have in my system it would take 2,097,152 of them to do it. Hell, the SDHC memory card — a single card the size of a postage stamp — that I put into my new digital camera is 8 Gigabytes of room and that’s not even the most spacious such card available. SDXC cards can range from 32GB to 2 Terabytes of storage for your camera/phone/MP3 player. #seb #computing #history #technology #RAM

This Giant Chunk of Metal Is 4 Kilobytes of Memory [Past Perfect]

What’s this gent holding? A toaster? Farm equipment? Part of an engine? Wreckage from a destroyed tank? Nope—that’s 4KB of ol’ fashioned IBM memory. That’s enough to hold 12% of my Facebook profile picture!
Editor-in-Chief of CNET Reviews Lindsey Turrentine discovered the rugged computer antique in her grandfather’s barn. Not a bad catch! Turrentine pointed out the wonderful irony that the image itself is 692 KB—meaning she’d only need to find 172 more of these memory modules and a tractor tr…

  1. @SEB,
    are there any camera/phone/MP3 player using RAIDed SXDC cards to cover for card failure?
    I presume the ECC on the cards is so good that individual file loss is not a problem?
    I need a little help understanding the state of the art here. Sure would be pissed off to lose 1 TB of data 🙁

  2. None that I am aware of, but I haven’t really looked for such a thing. From what I’ve read it is possible to have three SDHC cards on the same bus, but the power consumption and speed limitations makes it less desirable than you might think.

    That said, these cards have a helluva lifespan. Most will do upwards of 1,000,000 write cycles before suffering significant issues. If you were to do constant writes to one it’d take around 4 years before you’d come close to that many write cycles. I’ve got an older 128MB Compact Flash card that I’ve been using since April of 2002 and which is still working just fine today nearly 10 years and two cameras since I bought it.

    Ideally, you’ll be making backup copies of anything on those cards on some other form of media. Or, better yet, use the flash cards to make backups of stuff on your standard hard drive.

  3. Way back, one of the first times Microsoft was accused of writing bloatware was when they couldn’t make their BASIC fit on a 8KB ROM cart for the Atari 8 bit. Running a million times that on a Mac mini feels like fat city.
