Thread: How to reduce the size of a gmapsupp.img file on a card???

Yep, I once had a china made 4GB SDHC that was really only 1GB. Hardware wise it was made to look as if it was 4GB but as soon as you use more than 1GB, the data got corrupted. It turn out that they design the bank of memory chips to share a single 1GB capacity. So boys and girls, always go for name brand and check full capacity usage ASAP. Try to buy from dealers that you can return easily.
One more things about memory, all memory design have parity check and retry (or re-read) mechanism to make sure it can get at data. If there are some bits not "fully" working (gray bits) it will retry and that will slow down access time. This "effect" also occurred when near capacity is used. Experience user knows not to use full capacity. I stop around 90% full.

I agreed about using bytes instead of prefix shorthand for clarification, but it's like asking people to use actual term without using acronyms (painful)

Little out of topic, but I think it's important to know.
