Best 250GB PCIe 3.0 MLC SSDs
There are 11 250GB PCIe 3.0 MLC SSDs compared here. The fastest is the ADATA SX9000 at 2800 MB/s read. Sequential reads across the group span 1900–2800 MB/s at 250GB.
Why this configuration
A 250GB PCIe 3.0 MLC 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.
250GB covers an OS and core apps with little room for a large game library.
Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.
Good fit: mainstream desktop and laptop builds.
