Thecus N2520 2-Bay NAS Review

File Transfer Tests

File Copy To NAS

This test quite simply put copies a single large file from the test system to the NAS box to show how well the system can sustain a single write speed. The 1.4GB file is copied to the drive and written in 64kB blocks.

File Copy From NAS

File copy from the NAS works in exactly the same way as the copy test, however it works in the opposite direction. The single 1.4GB file is read off the NAS in 64kB blocks.

Directory Copy To NAS

In the directory copy to NAS test, a directory tree representing that of a typical commercially available office suite is copied to the NAS to trace the bulk copy of a complex directory. A total of 2833 files making up 247MB are moved but the file sizes vary considerably with an average size of 41.4kB. Due to the varying sizes of the files, only around 50% of the writes are sequential.

Directory Copy From NAS

In the same way that the file copy from NAS traces the same file back across to the test system, the directory copy from NAS does exactly the same but to the entire directory that it copied across previously.
