back to article Microsoft's 32GB Surface RT has 16GB of free storage

If you've saved up $499 for a 32GB Microsoft Surface RT, you might want to save a bit more for a capacious microSD memory card, or at least break out one of your external USB drives: according to Microsoft, half of that 32GB will be unavailable for your files. Microsoft has published a support note that details how 16GB is all …

And where did they get their figure of 32 decimal gigabytes?

Flash chips come in binary gigabytes.

Have you ever actually tried to buy large capacity flash chips? Or even used a USB flash drive? They are generally metric sizes. These are all far eastern manufacturers and if they can save 7% die area and claim the same capacity to you bet they will. It isn't as if there is any fundamental needed to fill out the memory to a nice binary size - we are not talking about parallel interface chips here.

I think, although I could be wrong, flash and RAM usually chips come in Giga and Mega BIT capacities, and hence inherently binary.

Re: And where did they get their figure of 32 decimal gigabytes?

While the flash blocks are indeed binary sizes and there may be a 'binary' total, some are reserved for wear and bad sectors and 32GiB of raw cells never ships as a 32GiB drive.

That 7% difference is very convenient for covering that hidden space without having to list 'odd' capacities though.

Formatting since always...

Excuse me but hasnt drive formatting always been this way? Not sure how anyone who owns a computer would not know you never get the full capacity. Half the space though is quite a bit used up, whats the size of the OS?

Except in this case you would reasonably expect stuff "in"rom" not to count on something like a tablet.

It's back to the days of 64k Commodore 64 with it's usable 49152 bytes of memory

Dont you mean "Im?" Correcting grammar on this or practically any other forum is a thankless pursuit and distracts from the topic at hand. Besides, if you do away with hints of this nature, how will you know whom to ignore?

Going back to the topic of the Slab's specs writ in Market Speak, why is it necessary to list the Cover port along with all of the other ports? It is a dedicated interface and, while important to the functioning of the device itself, is much the same as listing a hinge for the screen of a laptop. Another example of MS almost getting it is the full-size (yay!) USB 2.0 (fail!). Yes, it differentiates the Slab from the iPad, but only feeds into the marketing story that Apple wants to tell in that it is Old Tech - hardly an innovation.

"Microsoft makes it easy for you to add more storage space"

No,

Microsoft make it easy for you to add an SD card to the tablet. However, the built-in apps, such as the Video player etc, can't actually see that additional space rendering it not so usable or easy for the average user to use.

Yes, there are ways and means around this, but they really should've had a media scanner a la Android to automatically scan the external media for playable files.

well, let's focus on what it CAN see on that card. It can see some things, right? Right?

that said, I still applaud MS (did I just say: "applaud MS"?!) for adding that sd slot. Miles ahead of Google and Apple. Even if what's on the card can't be seen by the the device, it's still... a revolutionary approach, no less.

I don't know where you got that information, but it's 100% wrong.

I've just copied an MP4 video file to a micro SD card and played it on my Surface RT.

@AC 10:07

I probably wasn't very clear - what I meant to say is that internal apps can't see videos on external storage automatically, and add them to the Windows libraries.

You have to manually browse to the SD card and find your videos, rather than just picking "Videos". My Galaxy Note 2 scans internal and external media and presents all the available video files in the Video Player app without me having to explicitly go look for it.

Re: "Microsoft makes it easy for you to add more storage space"

So your complaining because your to lazy?

Yes it is a nice to have feature , but your first post did say it couldn't see them which is wrong. Most people are used to finding external media themselves.

If I have inserted a full (of say text files, PDF's etc) 64GB sd card into a slot then thought "I will watch a video" I don't want my tablet scanning that 64GB if it does not have video files on them.

That is just me though, you (and others no doubt) obviously would and thus it would be good if it were added to the options in the future.

"Most people are used to finding external media themselves. "

*Most* people would probably never use external media, beyond sticking a DVD or a CD into a laptop. However, having done so, regular Windows would prompt them what they should do with it.

I'm not talking about the tech savvy user here (who are very much in the minority) but the mums, dads, grandads and grandmothers who aren't particularly computer literate.

P.S. Having already "corrected" the error in my original post, it's a more than a little churlish to take me up on it again, don't you think? The point stands that media on your SD card does not end up in your Windows libraries unless you are prepared to jump through hoops to do so, and that is a fail in my opinion. YMMV.

Not really - it's been done before!

When the Motorola Xoom was originally launched, it did so with an SD card slot that the OS couldn't see at all! :)

Re: 5GB for recovery partition

...yet a full Win8 64 install DVD contains just 3.3Gb (before magically expanding to closer to 16Gb installed). Office must be impressively fat. Or they just forgot to compress any of it.

a further comparison

Compare it with even leaner Android. No, compare it with x86 GNU/Linux of a major distro, fitting in 1GB when compressed and occupying 5-7 GB of disk space (even with full LaTeX suite, Emacs, a bunch of CAS, DBs etc)

Youch...

Then again, did anyone seriously expect Microsoft to not be bloaty?

Looks like they didn't spend much time trimming things down, and simply recompiled Windows 8 for the tablet architecture. There's probably still complete support for the ISA, AGP, PCI and USB3 in there!

I did. I've read Dean Takahashi's book about Xbox and it said that BillG agreed to trimmed down OS on Xbox (while initially he was all for full blown Windows there). I think BillG/SteveB need to spend more time thinking / less time drinking

I was explaining to a friend the other day how the 32GB in her iPod would only *ever* be 32GB, but that the "couple of gig" in her new (and cheap) Android phone could be as much storage space as she could ever wish for, simply by buying more memory cards...

GB or E9

If the sales people insist that 32GB is 32*10**9 bytes, they should be compelled by the Trades Descriptions Act to write 32E9 bytes.

Other reservations?

Will Microsoft have any other reservations in their tablets?

* Reserving half the CPU for DRM, Genuine Advantage, and virus scans

* Reserving half the display for ads

* Reserving half the network bandwidth for updates

I know I have MY reservations....

16GB just for the OS, sounds like to make Windows RT Microsoft just recompiled the Windows 8 binaries for ARM and then locked it down so you could only install software from the Windows store and left all the other crud for full fat windows in there that won't be needed. Of course the surface comes with Office installed so that bound to take up a chunk of the space whether you want office or not.

To compare the OS restore software for my Ainol Android 4 tablet fits on a 1GB SD card with just a few hundred meg of free space left

hazarding a guess here not owning a surface rt but presumably the applications on the device e.g. office take up a portion of that 16gb as well......

So what? It isn't like Apple does it any differently when they sell iPxxx devices. If they do it differently then why is there note 2* on the bottom of tech specs page of each device?

"2. 1GB = 1 billion bytes; actual formatted capacity less."

Meaningless

There's no such thing as a decimal gigabyte and the term gibibyte is as meaningless as counting in 1000s on a computer system. Memory on all computers (it has nothing to do with Windows) is counted using binary - just because that's too complicated for sales people and computer illiterates to add up doesn't mean you can change it. That would be like teachers being allowed to tell kids 90 degree angles are 100 degrees or Pi is '3' just because geometery is too difficult for thickies to understand. That may be true both of people who buy PCs and what passes for maths students today, but it doesn't make changing the numbers correct.

Re: Meaningless

The BIPM, IEC and IEEE all disagree with you, and define a gigabyte as 10⁹ bytes. You may not like it but that is reality. If it is a choice between using definitions devised by recognised international standards organisations and a semi-anonymous poster on El Reg I know who I will trust.

Re: Meaningless

Exactly,

Kilo = 10^3

Mega = 10^6

Giga = 10^9

The fact that it's bytes and not grammes or metres is irrelevant or you actually think that a Kilometre is 1,024 metres?

Re: Spectacularly Refined Chap

IEEE Std 1541-2002 is relevant here given the whole standard is on the 10^9/2^30 issue. Paragraph 4.1 is cut and dry:

The SI prefixes shall not be used to denote multiplication by powers of two.

I see you've already been thumbed down. I'm not surprised. After all, of course some anonymous nobody commenting on a discussion forum knows better than a recognized international committee of experts.

Well done on the sarcasm Rebecca, but the Spectacularly Refined Chap actually was saying what you said, before you, and in a less unpleasant way.

And (slightly off-topic, but...) while standards bodies are important, it's not that IEEE are experts in anything that makes them right, it's the fact that they define the standard. It could be done by a five year old, as long as everyone else abided by his/her standard.
