Rotating drives have an enormous order of 20 msec dead time seek time plus rotational latency after you tell them to write or read the data, before the heads have been moved to the data location and the data can actually be retrieved or placed on the platters.

This is where the speedup of a RAID comes from. For best performance, you need a drive or RAID for each Source and for each Destination and for each Scratch you will be referencing at the same time. Rotating drives today are limited by the rotation speed of the platters. A drive with a large cache will test modestly faster on random writes, since the first few blocks are written to the cache, then copied to the platters.

Otherwise, rotation speed is king. SSD drives are fast because they have have miniscule access times. But they are expensive and smallish, and are not an option for everything. Dec 9, For an individual user keeping the internal drives separate is almost always much better.

Setting it up with separate drives you need a boot drive, and a backup for the boot drive. Who cares if it boots a little faster? We want our computer to work faster.

Mac Pro RAID card under Windows | MacRumors Forums

Faster DATA access will improve performance a lot more than speeding up the operating system drive, especially these days when pretty much the entire OS is stored in RAM. Where you gain the most performance is speeding up the DATA storage. This is always true if you manipulate large files or lots of files, like photos or video.

External storage for your RAID makes a lot more sense since it is expandable. Not possible with the internal RAID card alone.

Slowest part of a computer is the mechanical spinning hard drive. Also the cheapest. Adding them together in a RAID0 increases capacity and performance.

Well, actually, the question then may be something more complicated. I originally had two 1T drives striped RAID 0 and added the third for that very reason, but it seemed to slow down. This is what prompted the RAID card question to begin with. Any ideas? To add a third drive correctly, the whole array must be rebuilt and the data restored so that the data is correctly stripped acrossed all three drives. I'm also not sure if that MacPro has an x8 or x16 slot, all i can tell is that the "standard" controller is an x4. As far as batteries, most enterprise controllers have them as an option, so if you do find a model that works for you but a battery isn't included, check for a kit it almost certainly exists.

MacOS compatible RAID Controller

Then you really don't need RAID at all. No, not at all. Unless for some reason OSX was "killing" your hard drives in the past you're going to be fine. Apple over charges for everything You're right That is correct sir! Which is exactly what I had in mind along with running Linux and Windows of course.
