Benchmarks: Atto Disk Benchmark
The DS1512+ and DS1511+ left a similar trail up Atto Disk Benchmark's graph. The 1K and 2K read tests were nearly identical, but the older unit pulled away when measuring 8K and 32K data performance. Both maxed out at around 125-130MB/s in the 128K test. Compared to Thecus' N7700PRO, the DS1512+ was slower out of the gate but eventually took the lead.
When measuring writes, the DS1512+ and DS1511+ provided virtually indistinguishable performance until the 32K and 128K benchmarks, where the newer drive slipped behind. Unlike the previous test, the DS1512+ was unable to pull ahead of the Thecus N7700PRO.
