ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 8192KB transfer sizes with the total length being 256MB.
Benchmark Results: ATTO showed Corsair Neutron XT 240GB SSD maxing out at 563 MB/s read and 544MB/s write in the standard overlapped I/O benchmark when connected to the ASUS Z97-A motherboard with the SATA III interface. This drive is rated at having up to 560MB/s read and 540MB/s sequential write speeds on ATTO, so we are just slightly above the advertised ratings so far. When we placed the drive into the Inateck FD1006C 3.5-inch USB 3.0 drive enclosure we were hitting 463MB/s read and 458MB/s write! These transfer speeds are higher than what we saw on the Inateck FE2006 2.5″ enclosure when using the same drive. It looks like the Inateck FE2006 and its JMicron JMS567 controller is just a tad slower than the Inateck FD1006C and the ASmedia ASM1153E controller!
