Which is faster for gaming?

The MP33. Its PCIe 3.0 x4 link reads up to 2.1 GB/s against the A400's 500 MB/s, so level loads and installs finish sooner.

Will the A400 work in my laptop?

Only if the M.2 slot supports SATA. Many modern laptops accept NVMe only, so check the slot type before buying; the MP33 needs an NVMe-capable slot.

Kingston rates the A400 at 1,000,000 hours MTBF; Team Group gives no endurance figure for the MP33. Real lifespan depends on how much data you write, and the larger MP33 spreads writes over more cells.

Is the A400 worth $155.00?

That Newegg price as of November 8, 2026 is high for a SATA drive of this class. Compare it against the MP33's price before deciding, since the MP33 is far faster per dollar at similar cost.

Can I use either drive for video editing?

The MP33 handles large video files better because of its NVMe bandwidth and SLC cache. The A400's 450 MB/s write speed makes it a poor scratch disk for 4K footage.

Do both fit the same slot?

Yes, both are M.2 2280. The difference is the protocol: the MP33 needs PCIe/NVMe support, the A400 needs SATA support.

Team Group MP33 1TB NVMe SSD vs Kingston A400 M.2 SSD 120GB

Buy the Team Group MP33 if you want NVMe speed on a PCIe 3.0 x4 slot; it reads up to 2.1 GB/s and is the faster drive for booting, gaming and large file work. Buy the Kingston A400 only if you need a cheap SATA M.2 drive for an older board or a secondary slot. The A400's best new price is $155.00 at Newegg as of November 8, 2026, while the MP33 has no price given here.
