There are 5 500GB PCIe 3.0 Toshiba SSDs compared here. The fastest is the Toshiba RD500 at 3400 MB/s read at 500GB. Sequential reads across the group span 1600–3400 MB/s at 500GB.
Why this configuration
A 500GB PCIe 3.0 Toshiba 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. Toshiba specifically tends to be chosen here for its firmware track record and warranty support.
500GB is a sensible OS-plus-a-few-games size.
Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.
Good fit: mainstream desktop and laptop builds.
