So who's made the leap to SSD?

Proin, you know better than that. Manufacturers use 1 billion bytes for their GB and 1 trillion bytes for their TB. A 2 TB drive is really about 1.8 TB.

Capacity: 1TB
So, we have 1024 gigabytes. Technically, that's going to be a bit less when formatted, but that's true with any drive, really, so I'm going to just scale it down to 1000 gigabytes as a small correction.

Actually, it has nothing to do with "formatting" the drive. It's the way that a computer measures a gigabyte (the right way) and the way the manufacturers measure a gigabyte (the wrong way).
A computer measures 1 gigabyte as 1024 megabytes and 1 terabyte as 1024 gigabytes. The manufacturers measure 1 gigabytes as only 1000 megabytes and 1 terabyte as only 1000 gigabytes. Thus the difference.
The speed increase of two striped SSDs over a single (or even striped) HDDs cannot be overemphasized, however.

Truth is the exact opposite. 1 gigabyte = 10^9 bytes. giga = billion. 2^30 != one billion.

I didn't want to go back that far...
AceHigh:
For my next computer I plan on 2 SSD disks in Raid 0 configuration and 5 2TB hard drives in Raid 5 configuration.
I really need to save money for that....
xShadow:
I didn't say the formatting was the reason, I just said that it's going to end up being less after you format it. >_>;
I knew that SOMEONE was gonna go head and start pointing that out, though. Took longer than I thought, I'll give ya that...
