Benchmarks: NASPT Continued
The NAS Performance Toolkit simulates various workloads to measure single-user performance. Office Productivity is a read and write test involving hundreds of small files, File Copy from NAS is a read test that uses a single 4.3GB transfer, while Directory Copy to NAS transfers a folder of 2,833 files using mostly 64KB writes.
Qnap's HS-251+ is evidently optimised for sequential read performance, and rightly so - it's a NAS designed primarily to serve multimedia content to your various devices.
