Disk Copy Benchmarks
AS SSD Copy Benchmark
We are using AS SSD’s Copy Benchmark tool to test the duration of file copy for ISO, Program, and Game data. The benchmark outputs the duration in minutes and seconds, and lower is better.
Lower is better, and the Samsung 970 EVO Plus 500GB comes in at 0.49 seconds, which is very close to the 970 EVO 1TB at 0.47 seconds, which is technically faster. There are cache size differences between the SSDs, but really this shows not much difference in large file transfer between them. The Teamgroup MP34 falls way behind here.
The Samsung 970 EVO Plus is technically faster than the Samsung 970 EVO 1TB SSD, but only very slight, they are pretty much neck and neck. The ADATA XPG SX8100 falls behind here quite a bit in small file sizes.
In-game transfers, using a combination of small and large file sizes, there is a technical slight advantage toward the new Samsung 970 EVO Plus over the Samsung 970 EVO, but it is very small. The ADATA XPG SX8100 falls behind here.
With DiskBench we place a 50GB single file onto the test drive. We copy this file from the test drive to a new folder on the test drive, volume to volume. This tests the performance the drive is able to copy a file from itself to itself as if you were copying files on the same drive. Results are in duration Seconds, lower is better.
This one was a bit of an oddity, copying a very large 50GB was slower on the Samsung 970 EVO Plus 500GB SSD versus the Samsung 970 EVO 1TB. There are reasons for this, one is the physical size of the SSDs, with the lesser 500GB capacity we are filling up more of the drive with a 50GB file and really exhausting those cache buffers, especially the SLC cache and DRAM capacity. There also may be latency differences between the two. The difference is not extreme. One thing is for sure, the Teamgroup MP34 performance is very extreme.
