    I bought a new 2Tb SSD but it shows up as 1.8TB SSD

    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)

    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.

      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.

    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.

    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 bastard clever 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.

      How long do you think digital computers have been around?

        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.

    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

    It is 2tb. If you look in your drive manager you will see: 2tb. The 0.2tb missing are from the formatting
