Hard Drive Capacity Confusion, Lucidly Explained

mrklin writes "James Wiebe of wiebetech.com has written a clear example of how hard drive capacity is calculated (PDF file) by hard drive manufacturers (base 10) and OS (base 2). He failed to name how the capacity should be described, though."

How much Porn will it hold?

This one will hold 30 days of Porn

Now, this one here will hold 45 days of Porn

Break it down to something Everyone understands

Now, now, now, this is just wrong!

Everybody knows you don't measure porn in days.

True porn afficianados know that you measure porn in terms of the amount of keyboard cleaning required.

Hmmmm

No.... I don't think I'll be doing that.

Your idea is good, but it needs a unit since "days of porn" clumsy. I propose the "ejac" which is one days worth of porn. Larger units are derived using the usual base 10 system:

decaejac
kiloejac
megaejac
gigaejac ... and so on

This is a handy unit since it can be converted into time (1 ejac = 20 minutes), liquid volume (1 ejac = 10cc), sound volume (1 ejac = 90dB) and distance (1 ejac = 75cm).

If we all pull together, with this as our common goal, we can make the ejac a truly universal unit.

Literally.

If we all pull together...

Then we'd just have a mess on our hands... and keyboards...

I'm somewhat disturbed that you've taken the time to measure these attributes of your performance.

I swear to god I actually did this--

I was in Fry's computer store one day with a few friends when saw a guy holding *two* 120GB drives (about the largest drives there were at the time and very expensive). I walked up to him and said in my best strong bad impression, "Ouhhhgghh I bet those would hold ALOT of porn!"

The guy turned bright red and didn't say a word :) But he knew :)

But seriously

[nefele]

The real units joke is starting to get old...

Re:So how do you say it?

[dtfinch]

It depends on how many times you've watched "Back to the Future."

Old chips, new drives

[Flakeloaf]

I don't know what he's talking about; my Pentium 66 insists that 1024 x 1024 x 1024 = 1,000,000 exactly.

Re:Damnit - It happened to me today!

[shadowcabbit]

Even better-- pay in Canadian currency. That way it really is smaller. "I paid you 299 dollars and ninety-nine cents, just like we agreed upon. The fact is, you never specified the American dollar or the Canadian dollar, so I just used the unit more convenient for me."

[Black Parrot]

> describe the size in terms of number of songs. (of course, /. regulars will describe in terms of how much porn)

I forget... is it 1.7 threesomes per song, or is it the other way around?

OMG! Size DOES matter. Now to recover all that deleted email.

In the pocket of the HDD manufacturers

[Zog The Undeniable]

Well, the article doesn't tell us anything we didn't know already. The only critical point is that 1GB in marketing-speak != 1024 x 1024 x 1024 bytes, and that is still outrageous after all these years. "Easy to understand"...I don't think so.

Now if the drive manufacturers really wanted to go decimal, they'd use a 10 bit byte...but that would mean they had to give you a bigger drive for your money!

Oh yeah, and did anyone else laugh like a drain when the author used "IBM", "hard drive" and "reliable" in the same paragraph? ;-)

Re:Does it matter anymore?

[dotgain]

Ah, the 32 gig limit. But that's the 32 x 2^30 B and not 30 x 10^6, so you could comfortably fit, oh, say /afiftygigdrive/ in it no worries.
