Samsung 883 And 983 DCT SSD Review: Enterprise Class Storage At Consumer Prices
Samsung SSD DCT 883 And 983 - SANDRA, ATTO Bandwidth & IOs
Next we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant for some quick tests. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on clean drives that lacked any partitions. Read and write performance metrics are detailed below.

ATTO is straightforward 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 64MB 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.
Once again we see the Samsung 983 DCT NVMe 960GB SSD offering lower write performance than its higher-capacity counterpart. The Intel SSD DC P4510 and Samsung 983 DCT 1.92TB drives, however, finished right on top of each other (give or take a few MB/s) in the write test. The two drives behaved very differently in the read tests, though. The Samsung 983 DCT drives finished well out in front until about the 2MB transfer size, where the Intel drive crossed over and offered up a few hundred additional MB/s.
Peak IOs also look fairly different across the drives. All of the drives represented here flatlined at about the 1MB transfer size, but with smaller transfers there are clear deltas separating them all. The Samsung 983 DCT drives offered clearly superior read performance, while the Intel drive offered much better writes -- at least with the smallest of transfer sizes.
