Test Setup

Please read our SSD Storage Review Format and Methodology article for an explanation of our test system, how we test, procedures, and goals for SSD reviews.

Lexar Professional NM800 PRO 1TB Gen4x4 NVMe M.2 SSD with Heatsink System Setup

We are using the motherboard’s current default BIOS settings.  We have DOCP enabled.  We are running the latest motherboard BIOS.  We have Windows 11 Pro configured to run in the “Best Performance” power profile.  Windows has the latest updates.  NVMe drivers are installed if present on the manufacturer’s webpage.

We compare SSDs on our graphs by PCIe or SATA version. For example, all PCIe Gen4 SSDs are on a graph for comparison, and all PCIe Gen3 SSDs are grouped together separately when reviewed. SATA is also grouped separately when reviewed. In this way, we are comparing similar PCIe or SATA performance, so that it doesn’t skew the results and you can see the best drive in that grouping based on the generation of performance.


Installation of the SSD went smoothly, this SSD does not need a special NVMe driver.  It uses the default Windows NVMe driver.  In CrystalDiskInfo we can see information on the SSD below.

We reviewed the Lexar Professional NM800 PRO 1TB Gen4x4 NVMe M.2 SSD, an SSD created for hardcore gamers, professionals, and creators alike. This SSD works great in a PC, laptop, or PS5 and is one-sided for easy placement. The NM800 PRO has an optional integrated heatsink, which makes this a great package deal. It is priced well, at a good value, and has top-tier PCIe Gen4x4 NVMe performance in its class with a DRAM cache. It does lack management software but otherwise offers a complete bundle with heatsink that has above average TBW endurance ratings.
