Testing & Results
To test the ADATA DashDrive Air AE400, I wanted to look for a few results. First, I wanted to see how fast the data would transfer wirelessly from the DashDrive Air to a mobile device compared to how fast the data would transfer normally through a card reader. To do this, I used ATTO disk benchmark to compare the speeds. Second, I wanted to see what kind of bandwidth the ADATA DashDrive Air AE400 would provide as a wireless hotspot. I used SpeedTest.net on my phone and laptop to compare the speeds. Finally, to test the charging capacity of the AE400, I charged phones. Big surprise there.
First up, let's check out the results from ATTO. This first chart represents my laptop reading from a standard SD card through the built-in SD card reader. Both the read and write max out just over 15 MB/s.
The next chart shows read and write speeds with the SD card connected through the DashDrive Air AE400's wireless network. The speeds are frighteningly close. I am quite impressed.
Running SpeedTest by Ookla I was able to determine any difference in bandwidth when using the AE400 as a mobile hotspot. This was a little difficult, as I ran into an error. I'll talk about that a little later, but to give a little background, I used my phone connected to a Cisco router, which was connected to my internet through a Linksys router. The two routers are both 802.11n and were connected via a Cat6 LAN cable. When testing, I was sitting within about a foot of both the router and the ADATA DashDrive Air AE400. The first image is of my phone connected through the Cisco router.
In this screenshot, my phone was connected to the wireless hotspot created by the ADATA DashDrive Air AE400, which was connected through the Cisco router. The loss in bandwidth isn't unexpected, but it does drop by about 40%.
Just for comparison, this is a speed test from my laptop in the same room, connected wirelessly to the Linksys router.
Finally, I tested the charging capability of the ADATA DashDrive Air AE400. After fully charging my Nexus S 4G (technically from 3%), I hooked it up to my work cell, a Verizon G'Zone commando android smartphone. It fully charged the G'Zone and when it was done, the indicator on the AE400 was orange. That means the DashDrive Air was between 25% and 50% charged. Since it still had some juice, I hooked up my wife's iPhone 4S, which as at 27%. The DashDrive Air fully charged the iPhone and finally, the indicator showed up red. I'm not sure exactly how much juice was left, but after charging three phones, it wasn't dead yet.
I have to say, I'm pretty impressed. The Nexus S 4G has a 1500 mAh battery, the G'Zone Commando has a 1460 mAh battery, and the iPhone 4S has a 1432 mAh battery. The DashDrive Air AE400 charged all three and still had some juice left. Based on that, I'd say ADATA was being pretty conservative with their estimates of charging the iPhone twice.
