The article says which card to use for what system but for there to be no dought will it nor work at all!
APPLE riginal RAID -OTHER, OS X Mountain Lion (10.8.4)
Right and they aren't worth using unless you absolutely must use SAS drives or RAID5. Otherwise, I woudl not touch one.
The Apple RAID card's main reason for existence is to compute the rapid checksums needed to support RAID 5. The backup battery for its cache is a nightmare. It is old technology and places a 2.2TB limit on the size of each drive.
RAID Mirroring, RAID Striping, and Drive concatenation are all supported directly in Disk Utility, and respected third-party RAID Applications such as SoftRAID.
Heck!
Im about to win an eBay auction for a blue Apple RAID card together with a pair or SAS 300gb cheetah 15.5k discs for 75 bucks *happy*. Would have been healthy fast upgrade for small investment I thought?!
Guess it probably would have been if the thing worked!?
Why doesnt it work? iPass cable or something like that?
Suppose I still want to go the SAS route with those drives for performance. Any other cards not too expensive that will enable SAS in the Pro?
I use my MP 4,1 as a photo edit workstation but I also keep it on 24/7 for home server, web server, nas, backup etc. So i like to use items that are made for round the clock usage.
Or i just get inexpensive SATA drives and SoftRAID them. So RAID 0+1 is no problem in software RAID?
Thank you guy for quick informed response
Why doesnt it work? iPass cable or something like that?
The newer design moved the "stuff" that was on the iPass cable into slot 4 and it gets picked up when the newer card is plugged into slot 4 (ONLY).
You will have to look into the RAID 0+1 stuff, that has been promised for Mavericks Beach (10.9), but I dunno whether you can do it today.
Does this mean an original RAID (blue) card will not work at all in a mac pro 4,1 (2009)?
