The german c't magazine performed such a test on SSDs some months ago. The article was quite long, so I skipped to the conclusion: in normal use, they should last for years.
Code: Select all
PARTUUID=1486ef1d-02 / ext4 defaults,noatime,commit=600,errors=remount-ro 0 1 tmpfs /tmp tmpfs defaults,noatime,nosuid 0 0 tmpfs /var/log tmpfs defaults,noatime,nosuid,size=64m 0 0
Google tells me that all modern SD cards do. For example:I thought most SD cards did not do wear leveling?
That sounds intuitively true. But is it?If wear leveling is in use then obviously buy a much larger card than needed.
My understanding from professionally designing with FLASH for decades, especially raw FLASH in embedded systems, is that without basic wear leveling FLASH memory cards would be nearly useless (dead after a thousand or so saves of a file). Some of the earliest FLASH I worked with in the late 1990's had a life spec of only 100 writes. That was OK for replacing PROM for application storage but obviously wasn't useful for much else.
Your suggestion is interesting - perhaps that's one thing "advanced" wear leveling does.
But under what conditions? Using an SD card as a computer system mass storage device doesn't usually fall under "normal use".
Yes, perhaps someone who reads c't magazine could let us know?But under what conditions?
I suppose the article is copyrighted, so I am cautious to quote. The beginning is here:
