Why does computer solid state storage size go up by double each time?
i.e. why do you get 8Gb, 16Gb and 32Gb but nothing in between, but with hard discs you get 250Gb or 350Gb or 500Gb or 1 Tb etc.?

Or, I dunno, talk about lunch.

( tangledupinblue hairy badge with moving eyes, Mon 11 Mar 2013, 12:04, Reply)

Because what they're got inside is a number of chips in series.
So in the 8gb one they're probably got 4x2gb chips, in the 16gb they've got 4x4gb chips etc. They keep the same number of chips and controllers cooling etc because it makes designing them easier.

You're not paying attention to this answer are you.
Why normal HDD's don't necessarily go up in the same way is because they're based on spinning disks. You can either have more disks or "plates" in higher capacity drives or most likely a better head for reading/writing and each disk can write a byte of data in a smaller area. As this has more variables they tend to just do them in 50gb lots.
(PsychoChomp, Mon 11 Mar 2013, 12:13, Reply)

Okay, I get the whole hard disk is different thing
but I'm confused about the doubling up thing if you take it back to the very begining. Can I assume that they don't work from Bytes and go up, they just invented 1 Gb chips?
( Bazongaloid, Mon 11 Mar 2013, 12:15, Reply)

Pretty much.
The SSD is a bastardisation of USB key tech, so imagine a bunch of USB keys all wired up with complicated mathmatics to make them work as a single drive.
It doubles because that structure is based on a bunch of seperate memory chips working together. It doesn't necessarily have to double, but in practice it does because it's the best way to get a range out quickly.

( Fucking hell Jeff I am not a robot, Mon 11 Mar 2013, 12:05, Reply)

But, but, but ...
It was the same with Megabytes, so you have 1Mg, then 2Mb then 4 then 8 then 16 then 32 the 64 so how did they get from that to Gigabytes but still using the same nice round numbers?

Oh wait, I get it "1Gb" is actually "1024Mb"? right? But no, that doesn't work Because once you're past 64Gb teh extra bit rounds it up, and that's not what happens.

And that's assuming you start from Mb, not just bytes.

Right. Memory is based on bits. There are eight of them in a byte.
there are 1024 bytes in a kilobyte, 1024 kb in 1mb and 1024 mb in a gb.

When you think 1TB, you're thinking in base ten, which is why it doesn't seem to make sense that it's not 1000kb. Because they use 1GB, they've taken to using 500mb (rather than the more accurate 512) etc as well.

It's just ease of labelling, really.
( Kroney, Mon 11 Mar 2013, 12:16, Reply)

Oh I see. So the fact that 1024kb actually equals
1048576 bytes dosent matter, because you're defining a Mb as 1024Kb, not the number of bytes is containins.

So each layer has a kind of reset factor compared with the actual number of bits involved.
( Bazongaloid, Mon 11 Mar 2013, 12:19, Reply)

Aaaah, which explains why when you buy a 32Gb SD card
you actually only get about 29Gb of storage because the 29Gb is the actual number of bits available, not the number of "bytes"

There you go.

( Kroney, Mon 11 Mar 2013, 12:22, Reply)

No.
That's because the quoted size is the raw amount of user data in the flash chips which is less than the actual amount of data since flash chips contain additional non-user data to protect blocks and store status information but less than the amount that the user will see since the file system and operating system will add an overhead and oh god this is tedious but everbody else is talking semi-informed shite and the nerd in me couldn't quite resist I'll shut up now kthx.

Okay clever clogs
but the amount you "lose" between the volume you see on the packet and what you get appears to be a bit proportional, so if it was just system storage surely that would be far less with a large chip rather than a small chip?

I'm genuinely curious, are you saying that the difference in bits between what we define as 1Gb and how many bits that would be if you started from 8 bits in 1 byte and had 1024Mb or whatever has nothing to do with the difference in perceived size?

(PsychoChomp, Mon 11 Mar 2013, 12:32, Reply)

See the other answer.
Hard disk platters were always quoted in decimal (i.e. 1000 bytes to a kB etc) to make them seem slightly bigger until consumers got a trifle miffed. Flash memory wasn't really a consumer product until fairly recently so the numbers quoted were more "honest".

( rachelswipe with a fork, Mon 11 Mar 2013, 12:30, Reply)

Most flash chips use 16 bit words rather than octets
and the main difference between platters and flash chips is that the former were conventionally quoted in decimal and the latter have always been quoted in base 2.

But apart from that you're ... well ... largely wrong but I doubt anybody really cares.
