In my 4GB card it was getting tight and that's why I only now a 8GB card dazugeholt. I rather it stocked data and mostly read only.
My 4GB card for more than 1 year but performed their service and will use less time and more times a week. Sign up now to data loss, just super!
In my 8GB card (7561MB) I have now with the c't H2testw tool once tested the read and write rate and for Class 2 hab I get the following values (min 2 MB / s.): Write rate: 5.84 MB / s in 21.35 min and read rate: 16.9 MByte / s min 7.27 (on average describe in full, or read)
All I can say really great memory card, am absolutely satisfied !!!
