Default OCZ had to slow down its SSDs because Mac OSX can't handle the speed

Now, this is quite unusual, and we decided to ask OCZ directly. We received an unexpected answer from Mr. Tobias Brinkmann, OCZ's Director of Marketing EMEA: "The Mac version has different read and write specs due to Mac OS limitations. It is officially validated by Apple but works on other systems as well."

You might be wondering, "what limitations?"... we conducted some research and discovered a reason. Folks, Mac OS X has an issue with drivers, and this was bound to happen - the Apple-written SATA controller driver gets saturated by a single SSD drive, yet alone several of them.

The only way to avoid this is by buying an external RAID controller that comes with its own drivers, independent of the built-in SATA drivers. Now, brace for impact - upcoming Mac OSX Snow Leopard WILL NOT fix this one in its initial release, we will have to wait for an Apple Update, if it ever comes out. The issue is present in all Mac OS X releases with SATA drive support, so you lose 10MB/s if you use a very fast SSD drive.
