CSCS evaluated two different PCIe attached SSD devices with various methods for analyzing bandwidth and IOPs.
The performance over SATA drives is huge as expected, by a factor of 20 in bandwidth and a factor of 1500 for IOPs. The results indicate, that SSDs are a valid alternative for SATA or SAS drives in terms of reliability, performance and field replaceability.
The observed IOPS and bandwidth results encouraged CSCS to continue the evaluation of these devices such as the deployment in GPFS metadata servers.
