Lexar EQ790 1 TB, five years of warranty review
A Gen 4 ×4 drive with the longest warranty on this shelf, five years, beside 7,000 MB/s read, 6,000 MB/s write and an HMB and SLC cache — with no current Amazon.com offer.
Amazon.com listed it on October 26, 2026, but no current offer passed our price check, so no price is quoted. The Amazon.com page exists, but nobody was selling the unit; a listing in that state is often a third-party import.
Models on this shelf that Amazon.com did sell on that date:
The title: Lexar EQ790 1 TB, M.2 2280, PCIe Gen4x4, NVMe 1.4, up to 7,000 MB/s read and 6,000 MB/s write, for PS5 and PC gaming. The two bullets name PCIe 4.0, NVMe, HMB and SLC cache, and the speeds. The description adds 3D NAND, PS5 compatibility, power management and a limited five-year manufacturer warranty.

The questions that come up before an order
What warranty does it have?
A limited five-year manufacturer warranty, stated in the description — the longest on this shelf. The KingSpec XG7000 and the Samsung 990 state three.
Does it fit a PS5?
The title and the description name the PS5. The console asks for a heat sink, and this listing names none.
Our score
8.0/ 10
The longest warranty on this shelf with both speeds in the title. It had no offer on Amazon.com on this date.
The buyer this one serves, among network and storage gear

Sources
Specifications: the manufacturer sheet for network and storage gear and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
A Gen 4 ×4, NVMe 2.0 drive with 7,400 MB/s read and 6,500 MB/s write, HMB and an SLC cache, and thermal management named — and no endurance or warranty term on its Amazon.com page.
Best for: A desktop or laptop Gen 4 slot where the cloning software and NVMe 2.0 are useful and the warranty can be confirmed separately.
1 TB · M.2 2280 · PCIe Gen 4 ×4 · 7,450 MB/s read · 6,500 MB/s write · 1,000K IOPS · HMB · 0.5 mm heat sink · no TBW or warranty
A Gen 4 drive with the highest read figure on this shelf, 7,450 MB/s, a random figure of up to 1,000K IOPS and a thin heat sink — and no endurance rating or warranty term on its Amazon.com page.
Best for: A desktop or laptop Gen 4 slot where the highest read figure on this shelf is wanted and a written warranty is not essential.
1 TB · M.2 2280 · PCIe Gen 3 ×4, NVMe 1.3 · 2,100 MB/s read · 1,700 MB/s write · no endurance, warranty or cache figure
The only Gen 3 drive on this shelf and the cheapest at $151.41 on Amazon.com on October 26, 2026: 1 TB in M.2 2280, 2,100 MB/s read and 1,700 MB/s write, and no endurance, warranty or cache figure.
Best for: A machine with a Gen 3 M.2 slot, where a Gen 4 drive would run at Gen 3 speed anyway.
