Which is better for gaming?

The Crucial T705. Its Gen5 speeds and DirectStorage support load games faster, and Crucial claims up to 15% faster AAA game loads than Gen4 drives. The SanDisk has no stated speeds to compare.

Do I need a Gen5 motherboard for the T705?

To hit 14,500 MB/s, yes. The T705 is backward compatible with Gen3 and Gen4 boards, but it will run at those slots' slower speeds.

Crucial rates the 1 TB T705 at 700 TBW, though its spec table also lists 600 TB. SanDisk gives no endurance figure for the GX 7100, so the T705 is the only one with a stated rating.

Is the T705 worth the extra?

If you have a Gen5 slot and move large files or play big games, yes. If you are on Gen4 or want 2 TB or 4 TB, the SanDisk is the more sensible fit.

Does the T705 fit a laptop?

The heatsink version is thick and may not fit a laptop. Crucial sells a non-heatsink SKU for tight spaces and motherboard heatsinks.

Which has better security?

The T705 lists TCG Opal 2.01 and AES-256 encryption. SanDisk lists no encryption for the GX 7100.
