SanDisk Ultra 3D 4 TB

This is a 4000GB 2.5" SSD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes. At roughly $0.24 per gigabyte it sits in the premium tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $953.69 price tag places it squarely in premium territory. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total.
