Which memory stick is better for PSP? Sony or Sandisk?

I don’t really think there is much in it and for save games I doubt you could even notice the difference. Not worth paying the premium for the Sony IMHO.

Simple answer – it’s the sandisk.

The reason is that the writespeed on Sandisks are much faster.

In the original firmware tools which required a lot of writes, if you had a sandisk, the reprogramming would take roughly 20 minutes. On a sony stick? over 2 hours. It’s a large difference.

It’s just a brand. Unless one has a significantly higher write speed on it, otherwise, you wouldn’t even notice a difference.

Which ever one is cheaper is better in my book.
