SiSoft SANDRA 2011



For our next set of tests, we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provided the results from our comparison SSDs. The benchmarks were run without formatting and read and write performance metrics are detailed below. We have also included SANDRA's detailed graph so you are able to see how the drive performs over time along with the average rated result.

Samsung rates its 470 series at up to 250MB/s reads, a claim mostly backed by Sandra's new 2011 benchmark. Our Sandra run turned in a drive score of 246.87MB/s, coming up just shy of the Samsung's max rating. That's also slightly slower than every other SSD we tested it against, though never by more than 5MB/s, which is negligible.

As we saw with HD Tune Pro, the Samsung 470 does a tremendous job with writes, typically a sore spot with SSDs. Samsung posted a 210.3MB/s write score in Sandra, the highest of the bunch by at least 15MB/s, and nearly 130MB/s higher than Intel's second generation X-25M. The secret sauce is no doubt in the controller, and Samsung has cooked up something special here.
