The head parking problem that I came across, and one that has been seen by others with other drives, is that drives park the heads, often with a very audible click, after quite a short period of inactivity. However, since any potential (minor) problems will be dependent upon exactly how the drives will be used, it's probably worth being aware about the APM features commonly found on smaller disks. How do you use the drive? What's bad about the head load/unload cycles? Does it cause wear and tear? Does it make a lot of noise? Does it make the drive unsuitable as a slave storage drive in a desktop computer?įor the use that you intend, I wouldn't predict any problems due to aggressive APM features.

You receive your QNAP NAS Ready To Plug 'N' Store. Then it's double boxed to protect the unit during shipping. Once the tests are complete we QA and pack the system back into it's retail box. Our tests put a greater emphasis on robustness, availability and error handling heavy loads. These tests can include extremes of workload (constant I/O's), CPU and memory use, thermal load (heat), clock speed, or voltages, bus and connectivity components, with the primary stress testing software aiming to test stability by trying to force a system to fail. This is undertaken in order to ensure stability when used in a normal environment. Our stress testing (burn-test) cycle commences for a minimum of 24 hours and extends to 48 hours if requested or required.

Our pre-burn testing prepares the NAS with an initial system and drive testing cycle to ensure that the integrity of the entire system is tested and passed with no issues at all.

Passed drives are then installed in the NAS with Volume and RAID set. The selected drives are batch controlled and tested using our HDD and SSD servers.
