Large File Transfer and Backup File Read

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 Corsair MP400 did well with an average speed of 822.3 MB/s. This workload uses a ~31GB folder, so this is being done mostly in the Dynamic SLC cache. We tinkered around with larger file sizes and found that the average write speed drops down around 125 MB/s once the entire dynamic cache is filled.

CustomRead 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 Corsair MP400 1TB drive finished with an impressive read speed of 1745.9 MB/s.
