Sabrent 2TB Rocket Q4 NVMe PCIe 4.0 SSD Review

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 Sabrent Rocket Q4 2TB finished with an average speed of 1283.6 MB/s, which puts the drive near the top of the pack.

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 Sabrent Rocket Q4 2TB drive finished with an impressive read speed of 1937.0 MB/s. This is a very impressive score, but it is using the latest NAND Flash!
