File Copy and Workstation Performance
DiskBench
With DiskBench we run two different tests. First, we place a 50GB single file onto the test drive. We copy this file from the test drive to a new folder on the test drive, volume to volume. This tests the performance of the drive’s ability to copy a single large file from itself to itself as if you were copying files on the same drive, it replicates this drive being your primary and only drive. Second, we do the same thing but with the SteamLibrary folder. The SteamLibrary folder is a 243GB folder containing 570 smaller files. This replicates a folder with varying different file sizes and copying those files.
Copying a large 50GB file from volume to volume the Lexar NM790 2TB SSD with Heatsink offers a much faster file copy time than the Lexar NM800 PRO, at 23% less time than the NM800 PRO, which is significant. It is also just slightly faster than the NM710 and competitive with the Teamgroup MP44.
This is something a gamer might do, coping your SteamLibrary or Steam Game Library folder. What we find here is very significant and important. The time shown is in minutes. With the Lexar NM710, you will be sitting 4 minutes to copy, and with the Lexar NM800 PRO, almost 3 minutes. However, the Lexar NM790 2TB with Heatsink SSD improves this time a lot, it’s 60% less time than the NM710 and 41% less time than the NM800 PRO. At just 1.6 minutes of waiting, it is competitive with the Teamgroup MP44 for large file copy time.
SPECworkstation 3.1
We are using SPECworkstation 3.1 and specifically the WPCstorage test. “The storage workload is based on storage transaction traces from a wide variety of professional applications engaged in real work.” It includes media and entertainment, product development, life sciences, energy, and general operations. Each program receives a score, and they are averaged together for an overall score, higher is better.
In SPECworkstation 3.1 WPCstorage testing, this test shows why the Lexar NM800 PRO is marketed as a Professional drive. The NM800 PRO doubles performance for workstation applications, and that is the SSD if workstation apps are your thing. This doesn’t mean the Lexar NM790 2TB with Heatsink SSD is bad though, for workstation applications, in fact, it’s the second fastest SSD here, beating the Teamgroup MP44 for these workloads by 2% and beating the NM710 by 10%.
