SPECworkstation 3.0.2 Storage Benchmark
SPECworkstation benchmark is an excellent benchmark to test systems using workstation-type workloads. In this test, we only ran the Storage component, which is fifteen separate tests.
SPECworkstation performance for the Lexar NM620 1TB is embarrassing. In both Product Development and Life Sciences, the NM620 manages to return the very lowest scores I have personally witnessed by a wide margin. The other disciplines are not quite as bad off, but nowhere does the drive approach the descriptor of ‘good’ in terms of performance.
Sustained Write Performance
This is not necessarily a benchmark, so much as trying to catch the post-cache write speed of the drive. While I am filling the drive with data to the 85% mark with 10 simultaneous write threads, I monitor the drive for the write performance to dip to the lowest steady point and grab a screenshot.
Keeping consistent with the rest of this review, the Lexar NM620 has terrible sustained write speeds. I estimated 30 MB/s for the fast majority of the time while filling the drive, dips below 20 MB/s were also quite common. Also, keep in mind, this measurement is taken when the drive is brand new; performance could potentially be worse if the drive is overly full or GC/ TRIM has not been run recently.
We monitored the idle and maximum temperature during testing with HWMonitor to get some idea of the thermal performance and requirements of the drive. Please keep in mind that our test bench is an open frame chassis in a 22C room, but with no direct airflow. As a result, this is not representative of a cramped low airflow case and is instead intended to model temperatures of a drive ‘on its own’.
Despite the objectively bad performance, thermals on the Lexar NM620 1TB still managed a somewhat toasty 70C during load.
Again, we are mostly looking for the absence of runaway thermals here during our testing rather than comparing drives to each other.
The Lexar NM620 1TB is $120 on Amazon and Newegg right now, which is wildly overpriced for the performance you receive. For $120 you could buy a Samsung 980 1TB, or a WD SN550 1TB for $110, either of which is significantly faster.
As I mentioned earlier in my review, my first point of judgment when reviewing any product is whether it matches its own advertising, and the Lexar NM620 fails completely on that front. This is not “next-level performance for intensive workloads” and it is nowhere near achieving the claimed sequential performance levels. Perhaps it should be “next-level below performance for intensive workloads” instead.
This is a poorly performing drive that costs more than its competitors. You should not buy it.
