I stumbled upon something weird while looking into some new HDDs today.
SATA revision 3.0 has a maximum transfer speed of 600 MB/s (as seen [url=http://en.wikipedia.org/wiki/Sata#SATA_revision_3.0_.28SATA_6_Gbit.2Fs.29]here[/url]), but is called SATA 6 GB/s. Now this is the part where my mind is full of fuck.
Isn't 6 GB = 6000 MB?
[url=http://en.wikipedia.org/wiki/Data_rate_units#Gigabit_per_second]"A gigabit per second (Gbit/s, Gb/s, or Gbps) is a unit of data transfer rate equal to: 1,000 megabits per second."[/url] Why the hell does it say 6 GB/s = 600 MB/s in the SATA name then? Shouldn't the transfer rate logically be 6000 MB/s?
I don't know what I'm missing, or if I'm just dumb as shit, but can someone explain this to me?
Megabit =/= Megabyte.
6000 megabits = 750 megabytes which is not far off from 600 MB\s
Wow, I feel really dumb now.
Why use the same shorteners for both bits and bytes though?
Gb vs GB.
gigabit vs gigabyte.

It's the same reason why they use 1,000 Megabytes in a GB, so when you get your precious 1TB hard drive you really have ~940 GB.
Right, thanks, goodbye.
6000 Megabits = 750MBps , MBit is not the same as MB.
uppercase and lowercase.
