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 MP600 CORE 1TB drive finished with an average speed of 986.0 MB/s and that put it in the middle of the performance chart. This performance result is 54% better than the one seen on the older Lexar NM610 1TB.

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 Lexar NM620 1TB SSD finished the task at a speed of 1371 MB/s! That is about 13% faster than the Lexar NM610 1TB model.
