Performance TestsThe test bench is composed of the
ASUS X55SV laptop, the one that I have used for all the Flash Drive tests I have done before.
When inserted, the
red LED from the bottom of the flash drive lights up and blinks only when we access data or copy information onto the flash drive:
After opening the Windows Explorer application, we can see that the drive is not an empty, it holds an application:
The flash drive comes formatted
FAT32 and the included application along with the
documentation in PDF format takes about 1MB of its total space:
The application that comes with this particular flash drive is meant to boost its read/write speed and it's named
USBest Turbo:
When loaded, the application has an information screen, which tells us the name of the flash drive, its capacity, the remaining free space and the
Turbo feature status; the Turbo feature can be activated by pressing the
Turbo ON button:
Enabling Turbo on Windows 7 x64 is a real issue, because
the drivers that USBest application is trying to install
are not signed for this particular OS and the device will end up in Device Manager with an exclamation mark:
To make it work we have to
disable the "Digital Driver Signing" in Windows 7; one temporary solution would be to
press F8 when booting Windows and selecting the option to disable the Digital Driver Signing check. With this operation done, we will be able to use Turbo Mode:
To test the drive speeds in non-Turbo and Turbo modes, I have used the
HD Tune Pro application, with its Benchmark tab:
APOGEE AstroDrive 16GB Turbo Off
APOGEE AstroDrive 16GB Turbo ONSummary Graph ( Read Performance )To test the
write speeds, I have used the
File Benchmark test:

real world tests, in which I have used the
Total Commander File Manager, to transfer a file from the HDD to the flash drive and back:
