Best 1TB PCIe 3.0 Plextor TLC SSDs
There are 5 1TB PCIe 3.0 Plextor TLC SSDs compared here. The fastest is the Plextor M9Y+ AIC at 3400 MB/s read at 1TB. Sequential reads across the group span 3200–3400 MB/s at 1TB.
Why this configuration
A 1TB PCIe 3.0 Plextor TLC 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. Plextor 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: everyday all-rounder use, from OS drive to game library.
