It wasn't that long ago that when you needed to transfer files from one computer to another you had to use the trusty old 1.44MB High Density, Double Sided floppy disk. Yeah, you know what I am talking about, this just shows how old I am. Well those days have passed, and year after year flash technology has increased and gotten smaller. Man, was it exciting when you had that 1GB thumb drive which carried hundreds more pictures and files but still not enough space to carry anything large. Well those days are just memories and now there are flash drives that offer many gigabytes of storage to carry anything you can think of, even whole operating systems.

One of those miracle drives is the ADATA Classic Series C702 flash drive with 16GB of spacey goodness. The ADATA C702 takes all this storage space and crams it into a tiny flash drive with a retractable connector. With capacities of 16GB and more you will no longer need to have a full external hard drive to tote those important files around saving you time and money.


Closer Look:

The ADATA Classic C702 comes packaged in a sealed blister pack. The font of the packaging lets you see the flash drive and the capacity at a glance. The back has the specifications and system requirements in ten different languages. One thing that caught my eye was the Works with Vista logo on the top left, and that it works with Windows ReadyBoost. Only the drive is included in the packaging so no lanyard or USB extension cable here.



Once the package is opened you can get a better look at the drive. The one sent to me for review is the 16GB Pearl white one with a retractable USB connector. To operate just slide the black lever on the side of the drive forward and the connector will slide out in turn. There is also a blue LED indicator to show when it is in operation.


The drive is rather small and lightweight measuring 67.2mm long, 20.4mm tall, 8.5mm wide and weights 12 grams. To give you a better idea here is the drive next to a US Quarter for comparison.



Now that I have your attention and interest lets move on to the software side of the ADATA Classic C702.


The ADATA C702 comes with no software either on CD or pre-loaded on the drive. When you plug in the C702 the pop up balloon will come up letting you know that the drivers are being installed for the device. Then a window will come up asking you if you want to open the device and view the contents or use it with the Windows ReadyBoost feature. The ReadyBoost feature will allow you to use space on the device to speed up the operating system, acting like Virtual RAM. Since the flash drive is able to be accessed quicker than a hard drive, this will allow you greater performance for the time the drive in the system. In the ReadyBoost properties you can specify up to 4096MB of flash drive space to be used for speeding up the system.








The drive comes formatted with the FAT32 file system. This can be re-formatted for use in other operating systems including NTFS, EXT3, and HFS. One thing you may want to remember is that 16GB is really 14.9GB formatted which is true with any storage device being less because of drive storage translation.


Now lets move on to the testing phase to see how well the ADATA C702 performs.


67.2 x 20.4 x 8.5 mm (LxWxH)
12 grams
Data Retention
Up to 10 years
1GB, 2GB, 4GB, 8GB, and 16GB





To test the ADATA C702's performance, I am going to use a benchmark program called Flash Memory Toolkit. Flash Memory Toolkit will test the drive with a low-level read speed benchmark and a read/write file benchmark. For testing, each drive will be plugged directly into a USB 2.0 port on the back of the motherboard so there is no variable caused with extension cables. I will be comparing the ADATA C702 against two other popular flash drives to get an idea of performance.


Testing Setup:

Comparison Drives:


Read Speed - Low Level Benchmark:

Now for the tests. First up is the Low-Level Benchmark. This test will calculate the average read speed in megabytes and the speed calculation factor. The first screenshot is the ADATA C702, the second is the Sandisk Cruzer Micro, and the third is the OCZ Rally2.




WOW!  I did not see that one coming. The ADATA C702 just blew the other two drives away, even the dual channel OCZ Rally2.


Read and Write - File Benchmark:

Next up is the file benchmark which tests the average read and write speed for 1MB, 2MB, 3MB, 4MB, and 5MB file sizes. Again the first screenshot is the ADATA C702, the second is the Sandisk Cruzer Micro, and the third is the OCZ Rally2.















Here the ADATA C702 was still twice as fast as the Sandisk Cruzer Micro but was taken over by the dual channel capability of the OCZ Rally2 in the write speeds. It did however still take the read tests by storm.


I must say I am amazed on how well the ADATA C702 performed. It offers blazing fast speeds and high capacities for not a lot of money. At about $70 for 16GB of portable storage that's a deal. The C702 outperformed other drives in it's class in all of the read speed tests, including the OCZ Rally2, which is a dual channel drive built for fast transfer rates. If you are in the market for a portable flash drive and don't need the frills, like encryption and U3 Smart software, I would definitely recommend the ADATA C702. If you are looking for those software perks, you might want to look at other drives that offer them, or you could always download open source versions such as, Rare Idea's PortableApps program, which worked flawlessly with the ADATA Classic C702 16GB Flash Drive.
