Link Depot 21-in-1 Card Reader

Performance:

To test the Link Depot card reader/writer, we performed a series of read and write tests on the following system:

After we plugged the Link Depot card reader into an available USB port and inserted a Memory Stick and a Compact Flash card. FedoraCore4 had absolutely no problems detecting either cards and then automatically mounting them. We were able to immediately begin transferring files to and from the device. During testing, we used an older Sony Memory Stick, which offers a 64MB storage capacity. For comparison purposes, we also performed these read and write tests on an Atech PRO-Gear Flash 10-in-1 card reader and a traditional Sony DSC-S85 digital camera. For our read benchmarking, we simply used hdparm and performed a timed buffered disk read to indicate how fast the memory card in the reader can sustain sequential data reads under Linux (hdparm -t /dev/sde). For our write tests, we measured the amount of time required to transfer a 45.6MB SmoothWall ISO from the main hard drive over to the external card (time cp smoothwall-2.0-manuals.iso /media/usbdisk). All of the tests were run three times and the average of the three was used, all of the read and write benchmarking were performed identical across all three USB adapter mediums.
