Best 128GB PCIe 3.0 TLC DRAM-less SSDs
There are 18 128GB PCIe 3.0 TLC DRAM-less SSDs compared here. The fastest is the HP EX900 at 2100 MB/s read, and the highest-rated for endurance is the Gigabyte NVMe SSD (1600 TBW). Sequential reads across the group span 560–2100 MB/s at 128GB.
Why this configuration
A 128GB PCIe 3.0 TLC DRAM-less SSD is an affordable NVMe step up from SATA. Gen3 is roughly six times SATA's throughput yet often costs little more, making it the easy default for a first NVMe drive or a laptop that only supports Gen3.
At 128GB this is really a boot or cache drive rather than a main library.
Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.
Good fit: everyday all-rounder use, from OS drive to game library; value builds and gaming where cost per gigabyte matters.
Look elsewhere for: databases, virtual machines and other sustained random-write workloads.
Ranked list
Speeds on this page are the manufacturer's 128GB ratings where published (15 of 18 drives), not the family headline figure. 14 of the 18 are rated slower at 128GB than at their fastest capacity. Rated writes at 128GB run 400–1600 MB/s.

The parts, explained
128GB suits a boot drive or a light secondary disk.
PCIe 3.0 x4 reaches about 3,500 MB/s — plenty for everyday use and gaming, and cheaper than Gen4.
TLC NAND is the mainstream choice — a solid balance of endurance, speed and cost.
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 128GB 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.
