2.72 TB divided by 256 KB, minus a GB or two for miner files.........
I really hate how it is technically 3 trillion bytes in size and they have the balls to tell you that is 3.00 GB instead of the 2.72 GB it actually is.
I get about 11400000 nonces on one of them.
Technically 1KB is 1000 Bytes, like 1 kilowatt (KW) is also 1000W, not 1024. Its windows thats using the wrong units here.
On the hard drive I have connected, it shows 3,000,260,562,944 bytes available after formatting.
Hold out 5 GB for free space and miner software, leaving 2,995,260,562,944 bytes available.
11,400,000 times 262,144 (number of bytes in 256 Kb) = 2,988,441,600,000 bytes. It fits!
