Is it for data throughput, number of RAID arrays I can create on controller, number of disks I can plug into controller or what else? No discussion is needed about the answer to the question which configuration provides the lowest price per gigabyte. Predominantly, Ethernet is used which is also of serial nature. Since the array logic is based in hardware, software is NOT required to boot. Post as a guest Name. ATA drives use a single processor for both which means that if the rotational positioning requires more adjustments due to factors such as rotational vibration or wear, more processor time will be dedicated for that which can affect the performance of the drive. On a parallel SCSI bus, a device e.
