As a comparison the fastest SSDs available right now can "only" write around 600MBs/second.
mine goes at about 1500MB/s

Actually, mate, it's 1024 bytes make a kibibyte, 1000 bytes make a kilobyte.
1 Terabyte is 1,000 Gigabytes (1,000,000,000,000) bytes; 1 Teribibyte is 1,024 Gibibytes(1,024,000,000,000) bytes.
This is why older hard drives said they had "X" capacity, but after partitioning and formatting had less capacity.
Not too difficult to understand, when you understand that base of the number system you're working with.

So, how do you get 1 Tb transfers to a drive? SATA3 is only rated 6Gbps so you'd need 167 SATA3 connections to the drive to sustain that. Since even current DDR3 SDRAM is slower than that (fastest currently is around 16Gbps), using a "memory type" interface wouldn't even be fast enough. Then again, would it be possible to have the HD replace RAM?
What's the read speed?
What's the MTBF (mean time between failure)?
And what about RAID configurations- say 10 in parallel: 8 striped for data, 2 for parity/ECC? That could theoretically increase the rate at least 4-fold.

Oh, is that why the system I am building, that says it has a max transfer rate of 6 Gb/sec in fact has a write speed of 400 MB and a read speed of 430 MB? (roughly speaking and keeping hand firmly on wallet)

SATA III is 6 gigabits per second, 8 bits in a byte, so the max theoretical speed is about 750 megabytes per second. The fastest SATA III SSD drives cap out at around 550 MB/s (Intel 520) in sequential read due to the controller, which is enough to saturate SATA II but not SATA III.
If you want something even faster look into RAID arrays and PCI-E SSDs.edit on 12/2/12 by C0bzz because: (no reason given)
Just one thing to remember with SSD's. They have limited write-endurance.
