The 4TB NM790 is a high-capacity Gen4 M.2 option for game libraries, large applications and media projects. Both bare and integrated-heatsink versions have been documented, making exact cooler configuration especially important when comparing otherwise similar Amazon listings.
Compare 4TB NM790 variants on a true like-for-like basis. For PS5, verify an included and fitting heatsink; for a laptop, check the bare drive dimensions.
A 4TB Lexar NM790 can be attractive when the buyer needs a large gaming library, photo archive or working-project drive in a single M.2 slot. The 4TB capacity changes the economics: compare the installed cost with two 2TB alternatives, the available slot count, and whether the motherboard provides an appropriate heatsink. For a PS5, the exact cooler configuration matters as much as the capacity.
This page accepts only genuine 4TB NM790 offers, keeping bare and heatsink-equipped variants distinguishable. The alternative section likewise restricts competing drives to 4TB rather than filling the page with cheaper 1TB or 2TB offers. A higher price on one listing should not be presented as a discount unless Amazon supplies a fresh reference price for that exact ASIN.

Detailed Lexar NM790 4TB - Prices, Fit and Buying Advice guide
Practical details that matter when comparing exact SSDs, capacities and configurations.
Who benefits from a 4TB SSD?
A single 4TB SSD can consolidate a large game library while preserving other motherboard M.2 slots. For video work it can hold current projects, but it is not a substitute for separate backup copies.
Two 2TB drives may cost less or provide more flexibility, but only if your motherboard has sufficient slots and lanes.
PS5 versus laptop fit
Lexar publishes a specific NM790 with Heatsink configuration for PS5. Its physical cooler is taller than the bare NM790, so fit must be reviewed before using it in thin machines.
When using the bare drive in a PS5, a compatible separate cooler must be factored in; choose the integrated version for simpler installation.
Avoid misleading 4TB marketplace listings
The card filter rejects seller titles that blend capacities, list only a case, or advertise an unverified NM790 model. It also recognizes official SKU differences where available.
Price per TB should be compared after identifying whether the included heatsink adds practical value to this installation.

Frequently asked questions
Is the 4TB NM790 double-sided?
Physical component placement can vary by revision; verify the exact 4TB part number and mounting clearance rather than assume all units share the same layout.
Can I use NM790 4TB on PS5 Pro?
Use the compatible heatsink model or a bare drive with an appropriate cooler, following Sony’s current fit requirements.
Should I buy two 2TB SSDs or one 4TB?
Compare total price, free M.2 slots, cooling and desired organization. Two smaller drives are not automatically faster in everyday use.
