Samsung SM843 Pro: Ultra Fast Data Center SSD
ATTO Disk Benchmark
ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc. This test was performed on blank, formatted drives with default NTFS partitions in Windows 7 x64.

Once the transfer size hit about the 64K mark, all of the highest performing drives we tested were fairly tightly grouped in both the Read and Write tests. The Samsung SM843, however, had a clear lead over the other drives with smaller transfer sizes.
