Grsync test - 2010-02-09 01

Date: 2010-02-09

Conducted by: Glenn

Purpose/Goal
Test speed of duplication between 2 hdds mounted in external enclosure, connected by usb2.0, using Grsync software to manage the duplication.

This test is intended to test the performance when duplicating many small files (average size of 10kB or smaller), as opposed to fewer larger files (see previous Grsync tests). The goal is to be able to estimate expected data transfer rates under similar circumstances.

Hardware/Software

 * Grsync
 * Intel PC running Ubuntu 9.10
 * Sans Digital 2-bay external hdd mount connected over USB 2.0
 * 2x NTFS formatted hdds

Procedure

 * 1) Run grsync: Applications>System Tools>Grsync
 * 2) Select source: /media/NTFS_M_01/source/Test/ [contains ~550,000 files of various formats; 585.7MB]
 * 3) Select destination: /media/NTFS_M_02/received/Test/
 * 4) select options:
 * 5) preserve time
 * 6) verbose
 * 7) show transfer in progress
 * 8) always checksum
 * 9) Execute transfer

Results

 * transfer successful
 * transfered 585.7MB [550,600 files] in 94:15 (16:31:15)
 * transfer rate ~6.2 MB/minute
