Speed Comparison
SATA SSD: Continuous read speed of 550MB/s, random read/write speed of approximately 100K IOPS. NVMe SSD: continuously reads 3500MB/s (6-7 times that of SATA), and randomly reads and writes over 500K IOPS. PCIe 4.0 is faster, reaching up to 7000MB/s.
Actual experience differences
Power on speed: SATA 15 seconds, NVMe 8 seconds. Software startup: Large software (PS, IDE) starts 30-50% faster. Game loading: Open world games load 20-30% faster. Daily office: Almost no difference can be felt.
Purchase suggestions
New installation: Choose NVMe M.2 interface for fast speed and small size. Old computer upgrade: SATA SSD has high cost-effectiveness, and the old motherboard does not have M.2 interface. Capacity: Starting from 512GB for system disk, large capacity for data disk.
Other Attention
NVMe generates a lot of heat, and high-end SSDs require heat sinks. TBW lifespan indicator, with high durability models selected for writing volume. Do not buy miscellaneous SSDs, as there is a high risk of speed and disk loss.
