Memory Stick Pro HG Duo 32gb Fragmented Question

Defragmenting a memory card is not generally recommended since it can shorten its life.

However, defragmenting and making a file contiguous increases the potential for recovery should the data be accidenatally erased/formatted, or the card gets corrupted.

So, I would consider an occasional defragementing is quite in order and a good practice.

Did only 1 time, wont need more defrag unless i was copying stuff to it again.
its going to be permanent data files on the memory stick,
so theres no way it can fragment by reading data only.

On normal HDD of PC im not the type to do normal defrag more than 1 time eitheir as i find uncessary,
i just do eitheir a quick defrag and then just defrag checked files if necessary.

OK. Without getting into a detailed discussion on the best backup strategy for important data (may vary from individual to individual) and sticking to flash memory cards/UFDs, the following factors need to be taken into consideration.

1.Flash drives store data as static charges. In theory, the static charge can dissipate over time. Data retention is conservatively estimated to be 10 years but much will depend upon the technology used (multi-level cell, single-level cell etc.,) and the quality of the chips.

2. Data endurance (shelf-life) apart, the USB connector hardware is specified to withstand only around 1,500 insert-removal cycles.

Taking these factors into consideration, it is recommended that you backup the data, format and then rewrite the data to the storage device once in two or three years and also transfer the data to another new card/UFD after two or three such rewrites.

And just one point on the backup strategy, backup on more than one device. The more the merrier.:)

Finally from what I have read " The best medium for long term storage are ARCHIVAL GOLD CD-R or similar brand. The storage medium on the disk is a thin layer of 24K gold so it will not oxidize. Data retention on this type of CD is expected to be intact even after 300 years. They are expensive compared to conventional CD-R."
