Hi all,
What are your thoughts on priorities when selecting L2ARC drives?
I'm unclear whether multiple L2ARC devices will effectively stripe for faster performance, or will just act as a plain span.
So, would it typically be better to have say, two 240GB drives instead of a single 480GB?
Also, how much difference would low latency play in L2ARC? (Considering my workload is heavily very-large-file based) I'm looking at the Seagate 600/600-Pro series. It seems that raw transfer rates are pretty similar, but the 600-Pro drives have class-leading latency. Would that be of any benefit, or would it be better to put the extra money into larger/more drives?
Or finally, would it be better just to go for the largest possible cheap consumer SSD, and have as large a L2ARC as I can get for the money? Does size trump performance for this application?
(Edit: eg. The Crucial M500 480GB is pretty much identical price to the Seagate 600 Pro 240GB, and not much more than the Intel S3700 100GB)
