Hello to all, I am wanting to upgrade the storage in my Mac Pro. Currently I run 4x WD VelociRaptors 160GB's in Raid 0 as my boot volume with a 2tb and 1tb in the optical drive bay. Now what I would like to do is replace the VelociRaptors with 4x WD Red 4TB's and put it in a Raid 5 config and run 2 Samsung 250GB 840 EVO's in a Syba Dual SSD caddy. I don't want to run the WD Red drives off the internal ports because of the lack of Sata 6.0G ports. Now from what I understand the best why going about it would be the get a card with Mini SAS so that I can still use the drive sleds. The card I was looking at with this - http://bit.ly/YSzkiW - The Newer Technology MAXPower RAID mini-SAS 6G 1e1i, this is from OWC and seems to be mac compatible. What I was wondering was, has anyone used this card or do they know of a better card in a similar price range that would do a good job. Having a card that OS X can boot to means nothing as I will be using a separate solution with SSD's for that. Thanks. James.
