OK so something I am wondering having bought a couple of new CF cards for my Canon 5Dmk4.
I change the cards periodically as a wedding photographer just for safety of knowing they are not so old, the card I have just changed is a Compact Flash 64GB sandisk Extreme 120mb/s and I changed it for an identical card , both cards are genuine and verified by sandisk as I always get a check from them as a precaution and the older card is coming up to 2 years.
I did a read / write speed test between the new and old cards and there seems to be a difference of around 20-30 mbs especially on the read side between the old and new card ( the newer one reading around 80-90 mbs consistently. The same lexar pro CFR1 reader was used for both cards and test repeated a few times with the same results.
So my question is after many uses does the CF card read/write speed actually reduce with age ?
Thanks in advance
