The answer is "Maybe yes, maybe no".
The reason is that SD "class" ratings are determined mostly by measuring large sequential writes, and that is exactly what most SD cards are optimised for. However, most disk operations on a Linux system are small random reads, with some small random writes thrown in for good measure. This kind of performance varies greatly between SD cards of the same class, and may even differ between two identically branded SD cards.
In other words, unless you're using the SD card in a camera, there's no guarantee that a Class 10 will be any faster than a Class 4.
