I recently bought a new flash drive and as I was researching for speed and price, I came across something rather odd.

At first I saw the Corsair Fast Voyager 8GB flash drive. Costs £17.23 and is rather fast at 32.7MB/s average read and 20.3MB average write according to this test.

Next I saw the Corsair Flash Voyager GT 128 128GB flash drive. It was more about curiosity to see this massive drive. The site also had a review on it. This drive costs £310.47. Quite a lot, but more surprisingly, not all that faster, with 31MB/s read and 23MB/s write.

So speed-wise, the drives are the same, so how about size-wise? For the 8GB drive you get 475.45MB per pound, while for the 128GB you get 422.17MB per pound. Not that big of a difference, but still more than 10% worse.

But here comes the real blow. In the review, the 128GB flash drive is pitted against the Corsair X128, a solid state drive with eSATA connection. Costs £321.97 and averages 94.2MB/s and 91.9MB/s for read and write respectively. Look at this page again and do the math.

Here is a table to digest these numbers.

Now tell my which is the most worthless buy…
