PCPer File Copy Test
Our custom PCPer-FC test does some fairly simple file creation and copy routines in order to test the storage system for speed. The script creates a set of files of varying sizes, times the creation process, then copies the same files to another partition on the same hard drive and times the copy process as well. There are four file patterns that we used to try and find any strong or weak points in the hardware: 10 files @ 1000 MB each, 100 files @ 100 MB each, 500 files @ 10 MB each and 1000 files at 1 MB each.
Both Samsung units did not fare well in the file creation test. The P64 appears handicapped by its reduced parallelism, dropping file creation speeds to roughly match those of the 80 MB/sec limited X25-M. Both Samsung units did manage to stick with the pack on our file copy tests.
The Indilinx units did well. Despite using SLC flash and half the chip count, the PhotoFast V4S stuck surprisingly close to the Vertex units. The Vertex Turbo showed an approximate 5% improvement over it’s brother. The Crucial CT64M lagged behind, though it should be considered that 64GB Indilinx units are rated at lower read and write speeds as compared to 128 and 256 GB models.
