I often find myself explaining the same things in real life and online, so I recently started writing technical blog posts.
This one is about why it was a mistake to call 1024 bytes a kilobyte. It’s about a 20min read so thank you very much in advance if you find the time to read it.
Feedback is very much welcome. Thank you.
Well it’s because computer science has been around for 60+ years and computers are binary machines. It was natural for everything to be base 2. The most infuriating part is why drive manufacturers arbitrarily started calling 1000 bytes a kilobyte, 1000 kilobytes a megabyte, and 1000 megabytes a gigabyte, and a 1000 gigabytes a terabyte when until then a 1 TB was 1099511627776 bytes. They did this simply because it made their drives appear 10% bigger. So good ol’ shrinkflation. You could make drives 10% smaller and sell them for the same price.
If a hard drive has exactly 8’269’642’989’568 bytes what’s the benefit of using binary prefixes instead of decimal prefixes?
There is a reason for memory like caches, buffer sizes and RAM. But we don’t count printer paper with binary prefixes because the printer communication uses binary.
There is no(!) reason to label hard drive sizes with binary prefixes.
It more accurately describes how much space you have and how you can expect to see it shown in your software when you actually install it somewhere.
So here’s the thing. I don’t necessarily disagree with you. And if this had done from the start it would never had been a problem. But it wasn’t and THAT is what caused the confusion. You put a lot of thought and research into your post and I can very much respect that. It’s something you feel strongly about and you took the time to write about your beef with this. IEC changed the nomenclature in the late 90s. But the REASON they changed it was to avoid the confusion caused by the drive manufacturers (I bet you can guess who was in the committee that proposed the change).
But I can tell you as a professional IT person we never really expect any drive (solid state or otherwise) to be any specific size. RAID, file system overhead, block size fragmentation, etc all take a cut. It’s basically just bistromathics (that’s a Hitchhiker’s reference) and the overall size of any storage system is only vaguely related to actual drive size.
So I just want to basically apologize for being so flippant before. It’s important enough to you that you took the time to write this. It’s just that I’m getting rather cynical as I get older and just expect the enshittification of every to continue ad infinitum on everything digital.
Pretty obvious that you didn’t read the article. If you find the time I’d like to encourage you to read it. I hope it clears up some misconceptions and make things clearer why even in those 60+ years it was always intellectually dishonest to call 1024 byte a kilobyte.
You should at least read “(Un)lucky coincidence”
Ok so I did read the article. For one I can’t take an article seriously that is using memes. Thing the second yes drive manufacturers are at fault because I’ve been in IT a very very long time and I remember when HD manufacturers actually changed. And the reason was greed (shrinkflation). I mean why change, why inject confusion where there wasn’t any before. Find the simplest least complex reason and that is likely true (Occam’s razor). Or follow the money usually works too.
It was never intellectually dishonest to call it a kilobyte, it was convenient and was close enough. It’s what I would have done and it was obviously accepted by lots of really smart people back then so it stuck. If there was ever any confusion it’s by people who created the confusion by creating the alternative (see above).
If you wanna be upset you should be upset at the gibi, kibi, tebi nonsense that we have to deal with now because of said confusion (see above). I can tell you for a fact that no one in my professional IT career of over 30 years has ever used any of the **bi words.
You can be upset if you want but it is never really a problem for folks like me.
Hopefully this helps…
Pushing 30 years myself and I confirm literally not a single person I’ve worked with has ever used **bi… terms. Also, I recall the switch where drive manufacturers went from 1024 to 1000. I recall the poor attempt from shill writers in tech saying it better represents the number of bits as the format parameters applied to a drive changes the space available for files. I recall exactly zero people buying that excuse.
I just think that kilobyte should have been 1000 (in binary, so 16 in decimal) bytes and so on. Just keep everything relating to the binary storage in binary. That couldn’t ever become confusing, right?
Because your byte is 10 decimal bits, right? EDIT: Bit is actually an abbreviation, BIT, initially, so it would be what, DIT?.. Dits?..
kilobit = 1000 bits. Kilobyte = 1000 bytes.
How is anything about that intellectually dishonest??
The only ones being dishonest are the drive manufacturers, like the person above said. They sell storage drives by advertising them in the byte quantity but they’re actually in the bit quantity.
No, they absolutely don’t. That’d be off by 8x.
The subject at hand has nothing to do with bits. Please, read what OP posted. It’s about 1024 vs 1000
Calling 1024 a kilo is intellectually dishonest. Your conversation is perfectly fine.
