Which is faster, the 990 PRO or the P310?

The 990 PRO is slightly faster on paper: 7,150 MB/s read and 6,450 MB/s write versus 7,100 MB/s and 6,000 MB/s. The gap is small in everyday use and larger in long writes.

Is the 990 PRO worth the extra money?

Only if you write large files often or want the flagship drive. For gaming and general use, the P310's speeds are close enough that a lower price makes it the better value.

Will the P310 work in my PS5 or laptop?

It is an M.2 2280 PCIe Gen4 x4 NVMe drive, so it fits most Gen4 M.2 slots, including a PS5 with a heatsink. Check your device's slot length and clearance first.

Neither listing gives endurance ratings, so durability can't be compared from this data. Both are major-brand drives; check each maker's TBW rating for the 1TB model.

Do I need a heatsink for either drive?

The 990 PRO runs warm under sustained writes and benefits from a heatsink or motherboard shield. The P310 is a Gen4 drive and usually runs fine with a standard M.2 shield.

Samsung 990 PRO NVMe SSD 1TB vs Crucial P310 1TB NVMe SSD

Buy the Samsung 990 PRO if you want the fastest, most consistent drive and can pay the premium. Buy the Crucial P310 if you want near-flagship speed for less and your PC or laptop only supports PCIe Gen4. As of November 7, 2026, the 990 PRO 1TB is $189.99 at Newegg.com; the P310 1TB has no price given here, so check its current store prices before deciding.
