Real World File Transfer
Let’s see how real-world performance was when writing a movie folder containing seven 1080P movies over to the SSD. For this test, we are going to measure write performance by copying a 30.6GB folder of movies off from the drive being tested back to itself to see how performance looks. This action is basically a long linear sequential write operation and punishes the SLC Cache on many drives.
When it comes to writing a bunch of data to the drive without any breaks, the SK hynix Gold P31 1TB did great with an average speed of 1219.8 MB/s. The 500GB drive came in behind that with a speed of 1068.8 MB/s.
Custom Read File Test
The next custom test that we are going to do is how fast each drive can read a compressed folder. For this we backed up a Steam copy of PlayerUnknown’s Battlegrounds for the test file. The compressed folder contains 59 titles and is 27.3 GB (29,409,916,771 bytes) in size.
When it comes to reading a compressed Steam Backup file the SK hynix Gold P31 1TB and 500GB drives finished ahead of any other PCIe 3.0 drive with speeds of over 1.8 GB/s!
