Why this configuration
A 100GB SATA MLC SSD is a legacy high-endurance choice. These older MLC SATA drives are slow by today's standards but exceptionally durable, which is why they still appear in always-on and write-heavy roles.
Usually chosen for: keeping an older system alive, or a rugged secondary/logging drive.
Good fit: budget upgrades, older PCs and second drives.
Look elsewhere for: large-file creative work where NVMe pulls ahead.

MLC NAND is older and costs more per gigabyte, but is very durable.
Common questions
Is SATA fast enough in 2026?
For an OS, apps and most games you won't notice the difference versus NVMe in daily use. NVMe pulls ahead mainly on large file transfers and load-heavy creative work.
How do the links to Amazon work here?
0 of the 4 drives listed have a direct product link; for the rest we link an Amazon search on the manufacturer part number, which lands on the right listing. We deliberately don't display stock or prices on this page — check both on Amazon, they change constantly.
