Sequential numbers look dramatic on a spec sheet — here is when they change your day.
A Gen4 drive like the CS3040 more than doubles the sequential throughput of a Gen3 CS1030, but most office workloads never touch that ceiling.
The difference is visible in video editing scratch disks, large 3D asset loads, database imports and any workflow moving multi-gigabyte files repeatedly through the day.
For fleet refreshes on SATA-limited machines, the CS900 remains the pragmatic upgrade.
