,Quote="Merkury, post: 37750, member: 172"]"Both of them works fine without formatting" I mean REGULAR formatting. It's my fault! I have to explain more clearly what I mean.
You said "defrag regularly to keep them running good". Flash drive (SD card) has no moving parts. The purpose of defragmentation HD is to minimize the disc head movements across the disc while it is reading the data. Less movements - faster data reading. I hope you know that regular formatting and defrag SD cards reduce their life.[/quote]
READ THE WORDS I did not say that
I said Defrag "drives" ( as in HDD's) and format SD cards
From a study done on this
Another possible explanation is that previous observations of high correlation between utilization and failures has been based on extrapolations from manufacturers' accelerated life experiments. [...] Taken as a whole, our data indicate a much weaker correlation between utilization levels and failures than previous work has suggested.
So, if your fear is that the extra work being down to defrag is likely to kill your disk-drive earlier, it seems that it might cause a borderline drive to fail earlier. However, this isn't a strong effect.
Another effect might be observed: If a drive has a lot of read operations per defrag, then the time saved in seeking the right block will add up, and effectively reduce the overall utilization of the the system.
Also SD cards in general have a write cycle life of about 100,000 uses so, if you formatted it once a week you would die long before it does.
