Which is better for gaming?

Both load games fast, and the T500's own figures cite 16% faster game loads over PCIe 3.0 drives. The T705 wins on raw speed, but in-game load times differ little, so the T500's extra 2TB is the bigger practical gain.

The T500 is rated 2,400 TBW, far above the T705's 700 TBW figure for its 1TB model. For heavy writes over years, the T500 has much more headroom.

Is the T705 worth the extra money?

Only if you have a PCIe 5.0 motherboard and regularly move very large files. At recent lows it cost $389.99 for 2TB against $259.99 for 4TB of T500, so you pay more for half the storage.

Will the T705 work in a PS5?

No. The T705 is listed for PC only, while the T500 lists PS5 among supported devices.

Do I need a heatsink?

Both are offered with heatsinks. Use one on the T705 for sustained Gen5 speeds; on the T500 the heatsink helps under long writes but check clearance in laptops.

The T500 lists laptop compatibility. The T705 is listed for PC, and its Gen5 drive and heatsink suit a desktop with a free PCIe 5.0 M.2 slot.

Crucial T500 4TB NVMe SSD vs Crucial T705 2TB NVMe SSD

Buy the T500 4TB if you want the most storage per dollar and a drive that fits a laptop or PS5 as well as a desktop. Buy the T705 2TB if your motherboard has PCIe 5.0 and you want the fastest sequential speeds for large file work. The T500's lowest recent price was $259.99 for 4TB, while the T705's was $389.99 for 2TB, so the T500 costs less and gives you twice the capacity.
