I've an SAS drive, but no controller (yet), looking to change some SATA drives to SAS. (SSDs will likely stay SATA). Looking around there's a variety of options.
All my disks are currently SAS 6Gb/s or SATA III. I'm thinking it's probably better to get a controller with cache, than go for a 12Gb/s one without. The H330 is a cheap-ish 12Gb, but I imagine the cache will help things more.
I'll be running in JBOD mode, currently using mdraid with an SSD bcache, but moving to ZFS with L2ARC SSD cache.
Any advice? I know hardware RAID with a cache is a lot faster, I'm presuming it's exactly the same when using software RAID on JBOD, with a cache.
