The result of marketing pushing base 10 numbers on an archiecture that is base 2. Fundamentally is caused by the difference of 10³ (1000) vs 2¹⁰ (1024).
Actual storage size of what you will buy is Amount = initial size * (1000/1024)^n where n is the power of 10^n for the magnitude (e.g kilo = 3, mega = 6, giga = 9, tera = 12)
Fact: This truth is intentionally manipulation.
OP is right with an applicable staturing the pic.
Solution: Sue the fuck out of all of them. Especially Samsung. Fuck Samsung everything.
its correct, the final size you see in the OS is not kilo/giga/terabytes but kibi/gibi/tebibytes. the problem is less of the drive and more of how the OS displays the value. the OS CHOOSES to display it in base 2, but drives are sold in base 10, and what is given is actually correct. Windows, being the most used one, is the most guilty of starting the trend of naming what should be kibi/gibi/tebibytes as kilo/giga/terabytes. Essentially, 2 Tera Bytes ~= 1.82 Tebibytes. many OS’ display the latter but use the former naming
Base 2 based displays and calling them kilobytes date back to the 1960s. Way before the byte was standardised to be eight bits (and according to network engineers it still isn’t you still see new RFCs using “octet”).
Granted though harddisks seem to have been base-10 based from the very beginning, with the IBM 350 storing five million 6-bit bytes. Window’s history isn’t in that kind of hardware though but CP/M and DOS, and
dirdisplayed in base 2 from the beginning (page 10):Displays the filename and size in kilobytes (1024 bytes).
Then, speaking of operating systems with actual harddrive support: In Unix
ls -lhseems to be universally base-2 based (GNU has--sito switch which I think noone ever uses).-h(and-k) are non-standard, you won’t find them in POSIX (default is to print raw number of bytes, no units).Technically correct with numbers is the only way to ever be correct, let alone right.
Also minus metadata overhead.
Yup, damn formatting also gonna take a chunk
This is intentional, they could offer proper TiB storage but Apple started doing this decades ago just to shave pennies and now it’s caught on

I bought a new 2Tb SSD but it shows up as 1.8TB SSD
[An image of a classical art piece. The man in the image is wearing a hat and has a peculiar facial expression. One of his arms is on a table, palm facing up. The other arm is in the air, with the pointer finger touching the palm. Near that hand is the caption “Where’s my 0.2TB”]
This was surprisingly hard to describe
But you did awesome!
I’d be thrilled if the SSD I bought ended up being almost 8x larger than advertised! Does beg the question of why you’re buying 250GB SSDs in 2023 but I’m not here to judge.
even 32 gigs would be good enough for a cheap laptop running non shit OS unless you want to store any bigger data or play games.
250gb ssd could be used as a boot drive while you use a hdd to store your files

Same here 256gb ssd owner ill prefer to get something a little bit bigger but I also have a secondary hdd though to store all my files on which makes everything all good

Instead of that we should protest against si k should be K
- B
- kB < — Imposter
- MB
- GB
- TB
- PB
(Since this is SI it’s powers of 10^3 not 2^10 when going one level up)
Wait until you find out about Calories vs calories
and
μshould beumaybe… why throw in a random non-latin character? is it for the sake of anti-anglocentrism?Can’t tell if this is sarcasm (I’ve been on the internet too much today sorry) but just in case the Greek μ (mu) stands for “micro” since ‘m’ is already used for “milli”
yeah, i get that, but many people just use
ubecause its more accessible (ascii and qwerty compatible), similar to writingμBittorrentasuBittorrent. imo i dont think its too big of a deal if it doesnt match the wordmicro, sinceμis already a bit of a stretch. this is just my opinion, im not advocating for a SI reform or anything :)
That’s for the magic numbers that hold the 1.8 TB together. They live in that 0.2 TB and if you kill them then the 1.8 TB fly apart at the speed of light.
It’s 2 TB, not 2 TiB. One is to the base of 10, the other to the base of 2.

government filling up a secret section of every factory-fresh hard drive with CSM and terrorist material in case they ever want to lock you away
yes officer thats what happened
Yah this bugs me so much!! On top of that how dare system OS take up so much space?
Imagine buying 14TB and find out that it is 12TB instead.
A 14 TB medium is always 14 TB, which is close to 12 TiB. Minus metadata of the filesystem and granularity of a allocation sector.
It’s the same way with lumber lol
A 2x4 is in fact not 2"x4"
Wait, what?
Yeah a typical 2x4 is actually 1.5"x3.5"
2x4 is (supposedly. I bet they have optimized this down too) the size of raw lumber before it was finished, that needs to remove some material off each side.
in small print 2TiB*
From wikipedia:
More than one system exists to define unit multiples based on the byte. Some systems are based on powers of 10, following the International System of Units (SI), which defines for example the prefix kilo as 1000 (103); other systems are based on powers of 2.
Your system calculates 1 terabyte as 1 tebibyte which is 2^40 bytes=1,099,511,627,776 bytes and the hardware manufacturers calculate 1 terabyte as 1 terabyte which is 10^12=1,000,000,000,000 bytes. That is where the discrepancy is.
200 GB thats nearly CoD Warzone
Which is nothing compared to what ARC survival wants. Games are ridiculous these days. I’m not giving up 1/10th of my storage for a fucking game.
They’ve been doing this for literally centuries.
I think it started out with a rare case of honest advertising. So for example 720K floppies were advertised as 720K. But then some
lying bastardclever marketer decided to start advertising their 720K floppies as 1MB floppies, sometimes but not always marked “unformatted capacity”.And of course this had the desired effect of making people buy their disks instead of the honestly marketed ones, because people didn’t read the small print and thought they were getting more storage, which was important before CDs were a thing and software distributions were starting to need multiple disks. So everyone had to start doing it.
This is as far back as my memory of the practice goes, so it may have started before 720K floppies were mainstream, but that’s why disk manufacturers now advertise the unformatted capacity of their drives instead of the formatted, aka usable, capacity.

So it’s Friday December the fifth, 80 AD, 5:30pm, and Mozes is hacking away on his clay tables to nail down the final tally of this week’s adminstration of the amount of cows his boss owns and he goes "Mother fucker! These romans again ripped me off, sold me a clay tablet that only allows me to count to 720 cows, not the 751 I got! FUCK! Now I need another tablet and start tallying from the beginning, you mother fuckers!
They’ve been doing this for literally centuries.

How long do you think digital computers have been around?
They’ve existed in at least two centuries
For centuries. Justification: Jesus was dead for three days: from Friday afternoon (3pm?), day 1, through Saturday, day 2, and into Sunday early morning (6am?), day 3. Total elapsed time 39 hours. Digital computers were around last century (19xx) and this century (20xx), which is two centuries by the same logic. Also two millenia, but I find “centuries” a more satisfying word. Colossus went into operation in 1943, so that’s 80 years elapsed time.
Fails to recognize exaggeration, thinks they’re clever.
Fails to aggerate, fails to be taken seriously
This is where garderobe manufacturers are technically right, but theyre still dicks by (ab)using the fuck out of it.
TB = factors of 1000 which humans use, TiB is factors of 1024, which computers use.
Yes yes, they have it correct, it’s 2TB but you’re selling less than expected and you fucking know it.
Then there is also the filesystem that takes a small required cut to store your files nicely but that is almost negligible
Like many have already said, there is a difference in units when talking about actual storage and the storage on the label.
I feel like some marketing team made the changes, because it is technically correct and “easier for normal people to understand”… But that makes it confusing when normal people plug it in so, that team should be thrown overboard.
Edit: easier not earlier
Also you’re losing space to file system stuff. So it will always look smaller than it is
