Less head and platter movement to get to the requested data, the faster it can transfer. The difference is pretty much negligible, though. Think of the WD Reds as WD Green 2.0, built a little better and with TLER (which doesn't matter with software RAID such as ZFS). The CCTL on the Toshiba's is also a moot point, since that won't be used I do not believe, in a ZFS array.
I still recommend the Toshiba as disk vs disk, they are faster than the WD Red (minimal) and cheaper. I don't really care for WDC, so I may be biased.
Only 8 euro difference between these drives, so that is not an issue.
A am, however interested in the speed difference, and even more in relieability / durability differences between the two.
