Ive gone through a couple of different SATA controllers on my main workstation and IMHO I have found that the marvell88sx controllers seem to work the best. Currently, I have a Supermicro SAT2-MV8 (http://www.supermicro.com/products/accessories/addon/AoC-SAT2-MV8.cfm). Low price point (~100 USD) and no pesky RAID chipset make it perfect for ZFS arrays and general workstation use. > It would be nice if we could get someone from the SATA team to join and > work with the community on this, maybe Steve can help by providing some > information on the device he has, and put that together with what they > may know already.

I will start digging a bit this weekend to see what I can find with respect to SATA tape commands, technical info on the Quantum DLT-V4, and getting familiar with the SATA frameworks from a developer perspective. On a personal note, other than the practical implications of having SATA tape devices functioning within Nevada, I am looking to get my feet wet working within ON and begin working towards becoming a regular contributor.
