RAID 0 in a Mac Pro

In today's computers with multiple processors and ever greater quantities of memory, the hard drive becomes an increasingly important bottleneck. It may be tempting, therefore, to combine the performance of multiple disks as we do CPUs to improve the overall performance of the machine. By default, the Mac Pro supports software RAID 0. It is a protocol in which the machine will distribute the writes simultaneously, and reads simultaneously on multiple drives in order to accelerate IO (striping). We have tested with the fastest hard disk at this time, the Samsung Spinpoint F1 with 32 MB cache. Our tests showed that this disc, without Raid, is capable of reaching sustained speeds of 105 MB / s for reading and 96 MB / s for writing (excluding cache), which is well above what other currently marketed SATA disks can achieve. To highlight the disk performance, we used the SpeedTools Utilities and its software QuickBench 4, which has the merit of providing reliable and reproducible results. We te
