Premium NVMe Gen 4 internal SSD

This 4 TB internal solid-state drive uses a PCIe 4.0 x4 interface and NVMe 2.0 protocol. It is built with V7 V-NAND 3-bit MLC memory and an 8 nm controller. The non-heatsink M.2 2280 form factor suits desktops and laptops that have their own cooling solution.

PCIe 4.0 x4 bandwidth ceiling

Sequential speeds reach 7 450 MB/s read and 6 900 MB/s write, hitting the practical limit of the Gen 4 interface. Random performance delivers 1 400k IOPS read and 1 550k IOPS write, a 65 % uplift over the 980 PRO. DirectStorage support lets games stream assets directly from the drive.

Non-heatsink M.2 2280 build

Without an integrated heatsink the drive relies on the motherboard or chassis for thermal management. The slim single-sided PCB fits tight clearances in compact boards and laptops. Power efficiency improves 50 % versus the 980 PRO, reducing sustained thermal load during long sessions.

Questions about this item

Which capacity version of the 990 PRO should I pick?

The drive is offered as a single 4TB model, so there is no smaller or larger variant to select from.

What do the 7,450 and 6,900 MB/s sequential speeds mean once the drive is installed?

They represent the maximum sequential read and write throughput the controller can sustain over the PCIe 4.0 x4 link, so large file transfers and game asset streaming hit those peaks when the system can feed data fast enough.

How does the PCIe 4.0 x4 interface limit real-world performance?

The four-lane Gen 4 connection caps theoretical bandwidth at roughly 8 GB/s, so the drive's 7,450/6,900 MB/s sequential figures are already running at the interface ceiling.
