Buy the SN7100 for a gaming handheld or tight laptop slot; buy the P41 for a desktop or workstation where sustained writes and encryption matter.

• Choose the WD_BLACK SN7100 if you are upgrading a gaming handheld or a slim laptop and want the fastest sequential reads in a single-sided, power-efficient drive.
• Choose the SK hynix Platinum P41 if you want a DRAM cache, hardware encryption and a higher endurance rating for heavy sustained writes.
