SSDs In RAID: A Performance Scaling Analysis

Benchmark Results: Iometer Streaming

Speed enthusiasts will get their money’s worth when it comes to sequential read rates. With five drives, the RAID array has peak data throughputs of 1000 MB/s (read) and 1122 MB/s (write). The latter is faster due to the RAID controller’s caching. More importantly, each added drive increases the performance by about the same value, scaling almost linearly.
