Crucial MX200 1TB and 500GB SSD Reviews: Affordable And Fast
SANDRA and ATTO Disk Benchmark
Next we ran SiSoft SANDRA 2014, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on unformatted drives and read and write performance metrics are detailed below.
It was a much tighter race in SANDRA, especially In read performance -- it was a virtual dead heat between Crucial's MX200 drives and Samsung's SSDs. SANDRA showed a bit of separation in write performance, with Samsung taking the lead by around 20MB/s.
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.
The MX200 drives again showed strong read performance, with a smooth curve as transfer sizes increase. They also performed well in ATTO's write tests without any wild variations like OCZ's Vector drive exhibited.
