I’ve always loved the performance of Corsair USB flash drives because they are known to be the fastest in the world. 3 years ago I bought a 4GB Corsair Flash Voyager GT which was the fastest back then and I am very impressed with the read and write speed until today. Well back then 4GB is a lot of space but today it is not even enough to backup a DVD which is 4.37GB. So I checked Corsair’s website and they now have GTR range which claims to be even faster than GT! I searched very hard in Malaysia and no one seems to be selling a 128GB Corsair GTR USB flash drive. Fortunately I’ve got a friend living the United States coming back to Malaysia for summer holidays and he’s willing to help me bring it over.

I went to Amazon.com and they are selling the Corsair 128GB Flash Voyager GTR at the price of $289.99. It’s a little expensive but I think it’s worth the price since I can store nearly 30 DVD discs contents into one small plug and play USB flash drive that I can carry around in my pocket without requiring external power. I’ve done a little benchmark to compare against my other USB flash drives and also an external Maxtor hard drive 7200RPM.


First of all, here is how the Corsair 128GB Flash Voyager GTR looks like. It comes with a durable and water-resistant rubber housing. The size is also much bigger compared to normal USB flash drives but it is still very small when compared to an USB external hard drive.

Now the most important thing is to see how fast can Corsair 128GB Flash Voyager GTR perform when compared to others. I’ve used Nirsoft’s USBDeview to test the read and write speed, and also DiskBench to test the drive’s speed in a real life situation with file copying, file creation, and file reading instead in a benchmarking environment. Higher number is better in the benchmark report below.

As you can see from the USB flash drive benchmark result above, the Corsair GTR read speed is even faster than the Maxtor 7200RPM external hard drive! As for the writing speed, it’s averagely around 27% slower than the external hard drive but it’s the fastest if you sort the list in Nirsoft USB Flash Drive Speed test according to write. The drives that are faster than Corsair GTR in the Nirsoft Drive Speed list such as TOSHIBA MK4018GAS, BUFFALO HD-CXU2, Seagate FreeAgent Go and SAMSUNG HD103UJ HDD are actually external hard drives. If you’re looking for the fastest USB flash drive, go for Corsair GTR and you will definitely love the read and write performance.

The old Corsair GT which I’ve used for 3 years still performs very well without problems. The frequently asked questions regarding Corsair’s flash drive wear leveling mentions that Corsair flash drives are built with memory components that can handle AT LEAST 10,000 write cycles. It will definitely last more than 10 years with their dynamic wear leveling technology.
