Lexar NM790 SSD buying guide

The Lexar NM790 is a fast PCIe 4.0 M.2 2280 SSD with a broad capacity range, including a bare 8TB model. The key buying decision is not just whether it reaches 7,400MB/s, but whether the intended device has appropriate cooling and whether the buyer needs a preattached heatsink variant.

Quick answer

Choose NM790 for strong Gen4 performance when it is priced competitively with alternatives. For laptops, check the bare drive; for PS5, consider the integrated-heatsink SKU.

 **Before buying**

Bare NM790 and NM790 with Heatsink are different physical products and are never merged into one listing.

Your buying guide**What matters before you buy**

Lexar NM790 is a popular Gen4 NVMe choice for users who want fast storage without automatically paying for Gen5. The primary decision is often not just capacity but configuration: a bare M.2 2280 drive and an NM790 supplied with a manufacturer heatsink may have different physical fit and prices. Laptops commonly need the bare version, while PlayStation upgrades need effective cooling within Sony's expansion-bay dimensions.

Compare genuine model and capacity matches instead of generic titles containing NM790. Check endurance and sustained write behavior alongside price per TB. For alternative brands, the most useful comparisons are similarly sized Gen4 SSDs such as Samsung 990 PRO, WD_BLACK SN850X or Crucial T500, when matching listings are available.

**Variant**Choose bare or manufacturer heatsink based on your device.

**Sustained writes**Consider endurance and long-transfer needs, not speed alone.

**Price/TB**Compare equivalent capacities of Gen4 alternatives.

Detailed buying guide

## Detailed Lexar NM790 SSD - Gen4 Buying Guide guide

Practical details that matter when comparing exact SSDs, capacities and configurations.

### Choosing an NM790 capacity

For an ordinary game library, 2TB or 4TB may balance upgrade headroom and price. The 8TB version saves M.2 slots but requires a much larger initial outlay and fit review.

Some buyer pages compare price per TB without considering thermal limits. Include the cooling solution and the intended form factor in the full price.

### Understanding bare versus heatsink

The bare NM790 can work under suitable motherboard heatsinks, whereas the integrated-heatsink model adds a preattached cooler that may not fit thin laptop bays.

Never use a bare SKU as a substitute for a PS5-with-heatsink recommendation without confirming a compatible separate heatsink.

### TLC and cache behavior

Lexar documents 3D TLC NAND, HMB and SLC caching on NM790 product pages. Performance outside the cache can differ from peak sequential claims.

Use ratings and measured independent reviews to establish long-write behavior, rather than assuming a 7,400MB/s peak persists throughout a multi-terabyte copy.

## Frequently asked questions

 Can NM790 be used for PlayStation 5?

Yes, the documented heatsink-equipped version is designed for PS5. The exact drive and cooler must fit the expansion slot.

 Is Lexar NM790 available in 8TB?

Yes, the bare NM790 is listed in 8TB; the integrated-heatsink configuration is listed only up to 4TB.

 Does NM790 need DRAM to be a good gaming drive?

Lexar uses HMB and dynamic SLC caching. Suitability depends on price, workload and measured performance, not a DRAM label alone.
