Analysis: Which Enterprise Capacity Point Performs Best?
SSDs are best for performance. SATA hard drives provide maximum capacity. Enterprise-class SAS disks are the workhorses positioned between them. But which enterprise hard drive capacity makes sense when there are several from which to choose?
Benchmark Results: Throughput
You’ll receive the best throughput performance from the 300 GB drive, followed by the 600 GB model. While we don’t think peak performance numbers really make much difference, the variance in minimum throughput may become important.
The SAS 6Gb/s interface is not yet maxed out. Reading or writing from or into the drive’s buffer happens at roughly 330 MB/s. This is also the case on other enterprise drives with a SAS 6Gb/s interface. Physical performance in getting data on and off the rotating medium remains the key performance characteristic.
