Lexar NM790 with Heatsink 4TB SSD Review

The PCMark 10 Full System Drive Benchmark uses a wide-ranging set of real-world traces from popular applications and common tasks to fully test the performance of the fastest modern drives. The benchmark is designed to measure performance of fast system drives using the SATA bus at the low end and devices connected via PCI Express at the high end.

The goal of the benchmark is to show meaningful real-world performance differences between fast storage technologies such as SATA, NVMe, and Intel’s Optane. The Full System Drive Benchmark uses 23 traces, running 3 passes with each trace. It typically takes an hour to run.

Traces used:

Booting Windows 10.
Adobe Acrobat – starting the application until usable.
Adobe Illustrator – starting the application until usable Adobe Premiere Pro – starting the application until usable.
Adobe Photoshop – starting the application until usable.
Battlefield V – starting the game until the main menu.
Call of Duty Black Ops 4 – starting the game until the main menu.
Overwatch – starting the game until main menu.

The 4TB Lexar NM790 with Heatsink displayed strong performance in PCMark10's Full System Drive Benchmark. It averaged 306MB/s for the six Adobe startup traces, the fastest being the 385MB/s for the startup test of Premiere Pro while the slowest was the Lightroom startup trace at 227MB/s.

For the Adobe usage traces it averaged 580MB/s for the five tests, with the fastest being the 1,277MB/s for the Adobe Photoshop heavy usage trace and the slowest, the Adobe InDesign trace at 277MB/s

The drive averaged 861MB/s for the three gaming tests, the fastest being Battlefield V at 1,101MB/s. The other two game traces Call Of Duty Black Ops 4 and Overwatch produced scores of 963MB/s and 521MB/s respectively.

When it came to the file transfers, the fastest was the cp1 Write test at 3,946MB/s with the drive averaging 2,224MB/s for the six file transfer tests.

With an overall bandwidth figure of 583.96MB/s, the 4TB Lexar NM790 with Heatsink slots into the third spot on the results chart behind Crucial's T500 drive and the standard NM790.
