This sale is either back or ongoing.
Picked up two of the 5 TB flavors of this drive a couple of weeks ago.
They're a bit noisier during access than my previous drives, but they are *fast*. 215 MB/s max read speed, 165 MB/s min, 191 MB/s, average, 8.1 ms access time during my testing. They're about twice as fast as the 2 TB and 3 TB 7200 rpm Seagates they replaced.
Thinking about getting one or two more this weekend too.
