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 WD_Black AN1500 did really well with an average speed of 1603.5 MB/s, which only slower than the Samsung SSD 980 PRO 1TB drive!
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 WD_Black AN1500 2TB AIC was able to read it faster than any other consumer storage drive that we have tested on this system!
