Best 500GB SATA DRAM-less SSDs
There are 71 500GB SATA DRAM-less SSDs compared here. The fastest is the Reletech P400 at 3500 MB/s read. Sequential reads across the group span 350–3500 MB/s at 500GB.
Why this configuration
A 500GB SATA DRAM-less SSD is a budget and compatibility choice. SATA won't win benchmarks, but it's the cheapest way to add solid-state speed and fits essentially any PC or laptop with a 2.5-inch bay.
500GB is a sensible OS-plus-a-few-games size.
Usually chosen for: reviving older machines, cheap capacity upgrades and second drives.
Good fit: value builds and gaming where cost per gigabyte matters; budget upgrades, older PCs and second drives.
Look elsewhere for: databases, virtual machines and other sustained random-write workloads; large-file creative work where NVMe pulls ahead.
Ranked list
The top 20 of 71 are listed. The full SSD catalogue filters on every spec.
Speeds on this page are the manufacturer's 500GB ratings where published (7 of 71 drives), not the family headline figure. 2 of the 71 are rated slower at 500GB than at their fastest capacity. Rated writes at 500GB run 400–520 MB/s.

The parts, explained
500GB is a comfortable OS-and-games starting point.
SATA III tops out around 550 MB/s, but it is the cheapest interface and fits any 2.5-inch bay or older laptop.
DRAM-less drives use the Host Memory Buffer (HMB) instead — cheaper, and fine for everyday use and gaming, with a small penalty under heavy random writes.
Common questions
Is a DRAM-less 500GB SSD good enough?
For gaming and everyday use, yes — HMB covers those workloads well. If you run sustained heavy random writes (databases, VMs), a drive with a DRAM cache stays more consistent.
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.
