SD Card read ahead speed change (from xda)

[Guest dandroidme]

... but then I downloaded the new version of SD tools and my speed seems to have gone slow again ?

That's because the SD tools app developer has removed a couple of the more schoolboy mistakes from his speed test algorithm and it's getting closer to producing an accurate measurement for typical file system usage now.

There's still a couple of things he needs to do then everyone can go back to a more appropriately sized read-ahead buffer.

My speeds went down. What's all that about?

Try a different cache size.

Try a different cache size.

Unlikely to work. What fibblesan is almost certainly seeing is the detremental effect this mod will have on access times once the storage media passes a difficult to predict threshold related to file fragmentation and usable free space.
