Best 1TB PCIe 3.0 Intel SSDs
There are 6 1TB PCIe 3.0 Intel SSDs compared here. The fastest is the Intel INTEL® SSD 670P SERIES at 3500 MB/s read at 1TB. Sequential reads across the group span 1800–3500 MB/s at 1TB.
Why this configuration
A 1TB PCIe 3.0 Intel 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. Intel specifically tends to be chosen here for its firmware track record and warranty support.
1TB is the capacity most single-drive builds settle on.
Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.
Good fit: mainstream desktop and laptop builds.
