Frequently Asked Questions
Is the speed difference noticeable in gaming?
No. Both drives load games instantly. MP600 and 990 Pro feel identical for gaming — your SSD speed is already overkill for any game. The bottleneck is GPU/CPU, not storage speed.
What about 4K video editing — can MP600 handle it?
Absolutely. MP600’s 4,950 MB/s is more than adequate for smooth 4K playback and editing. The 990 Pro’s extra speed (7,100 MB/s) only matters for 8K workflows or extreme effects processing.
Why is 990 Pro so much more expensive?
Samsung’s premium brand, manufacturing costs for extreme optimization, and marketing budget drive the price. The speed advantage doesn’t translate to proportional price — you’re paying for brand prestige.
Which is more reliable?
Both are excellent — 5-year warranties, proven reliability, comparable MTBF ratings. Samsung has slightly better brand recognition, but Corsair’s track record is equally solid. Choose based on performance needs, not reliability.

How we verify this guide
Every compatibility figure here is checked against manufacturer specifications, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
