Our Picks
Fastest1 of 6
Samsung 990 PRO 1TB
The 990 PRO 1TB offers 7,450MB/s reads and 6,900MB/s writes, the top rated speeds among the 1TB Gen4 drives here.
Best for
- Boot drives for high-end builds.
Skip if
- Skip it if price comes first: the NV3 1TB cost less when we checked.
Why we like it
Its random read and write are 40% and 55% faster than the 980 PRO, and Samsung's nickel-coated controller manages heat in slim laptops too. Nothing else here matches its 7,450MB/s rated read speed; the NM790 1TB comes closest at 7,400MB/s. It matches the SN7100 1TB on rated write speed (6,900MB/s).
It also comes with Samsung Magician software for firmware updates. It is an M.2 2280 drive, the standard length on desktop boards; check which of your board's slots it goes in, as some share lanes with SATA ports. It runs at full speed in any PCIe 4.0 M.2 slot and still works, slower, in a PCIe 3.0 slot. It was priced above the SN7100 1TB and below the T500 1TB at the time of writing.
Key specs
- Sequential read
- 7,450MB/s
- Sequential write
- 6,900MB/s
- Interface
- PCIe 4.0 x4

Best Value2 of 6
WD_BLACK SN7100 1TB
The SN7100 1TB offers 7,250MB/s reads and 6,900MB/s writes on TLC NAND, close to the 990 PRO for less.
Best for
- Most builds.
Skip if
- Skip it if price comes first: the NV3 1TB cost less when we checked.
Why we like it
Its 7,250MB/s rated read speed ranks fourth of 6 here, behind the 990 PRO 1TB (7,450MB/s) and ahead of the NV3 1TB (6,000MB/s). It also comes with next-generation TLC NAND and a design aimed at handhelds and laptops as well as desktops. It is an M.2 2280 drive, the standard length on desktop boards; check which of your board's slots it goes in, as some share lanes with SATA ports.
It runs at full speed in any PCIe 4.0 M.2 slot and still works, slower, in a PCIe 3.0 slot. On price it sat fourth of 6, between the cheaper NM790 1TB and the pricier 990 PRO 1TB, at the time of writing.

How We Chose These 1TB Gen4 SSDs
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

- How these picks were ranked
- We compared six drives on rated read speed, rated write speed, interface and warranty as the makers state them. These are research figures, not bench results: 2 of 6 picks leave out rated write speed.
- What every pick has in common
- All 6, from the 990 PRO 1TB to the NV3 1TB, state rated read speed, interface and capacity and share PCIe 4.0 x4 interface and 1TB capacity.
- Where the specs have gaps
- The SN5100 1TB and the NV3 1TB give no rated write speed; the 990 PRO 1TB, the SN7100 1TB, the T500 1TB and the NM790 1TB give no warranty.
- Price range
- At our last check the picks ran from the NV3 1TB ($150 to $250) to the T500 1TB ($250 to $500).
What to Look for in a 1TB Gen4 SSD
Key buying criteria so you get the right fit the first time.
Rated read speed
Here rated read speed runs from 6,000MB/s on the NV3 1TB to 7,450MB/s on the 990 PRO 1TB, a 24% spread. The NM790 1TB comes second at 7,400MB/s, in the same price tier as the 990 PRO 1TB.
Rated write speed across these picks
Across these 4 picks rated write speed spans 6,500MB/s (the NM790 1TB) to 6,900MB/s (the 990 PRO 1TB). For less, the SN7100 1TB is the runner-up at 6,900MB/s. The SN5100 1TB and the NV3 1TB give no rated write speed figure, so 4 of 6 picks are compared here.

An M.2 SSD installed on a motherboard Extras that separate them
The NM790 1TB: HMB in place of onboard DRAM. The SN5100 1TB: the lowest price among the 1TB TLC-class drives here. The NV3 1TB: 6,000MB/s rated reads on PCIe 4.0.
Where your budget lands
$150 to $250 buys the NV3 1TB, the SN5100 1TB, the NM790 1TB, the SN7100 1TB and the 990 PRO 1TB; $250 to $500 buys the T500 1TB at our last check.
