Lexar NM610 1TB NVMe SSD Review

Custom File Transfer and File Read Tests

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 Lexar NM610 1TB drive finished with the lowest average speed of all the NVMe drives and that would be 639.6 MB/s. The good news is that this is still 3x higher than the SATA III SSD in the chart.

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 NM610 1TB drive finished with an average read speed of 1217.3 MB/s, which is on the low side for the 12 NVMe drives that we have tested on this system.
