Best 100GB SATA MLC SSDs
There are 4 100GB SATA MLC SSDs compared here. The fastest is the Kingston SSDNOW E50 at 550 MB/s read at 100GB, and the highest-rated for endurance is the Kingston SSDNOW E100 (3906 TBW). Sequential reads across the group span 400–550 MB/s at 100GB.
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.

The parts, explained
SATA III tops out around 550 MB/s, but it is the cheapest interface and fits any 2.5-inch bay or older laptop.
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.
