I remember that early flash drives could take only a limited amount of write cycles before they went kaput - is that not an issue anymore these days?

Martin says, November 21st, 2007   

Ace that is still the case, taken from Wikipedia:

Limited write cycles. Typical Flash storage will typically wear out after 100,000-300,000 write cycles, while high endurance Flash storage is often marketed with endurance of 1–5 million write cycles (many log files, file allocation tables, and other commonly used parts of the file system exceed this over the lifetime of a computer). Special file systems or firmware designs can mitigate this problem by spreading writes over the entire device, rather than rewriting files in place.

That doesn’t sound very comforting - especially when using them as a boot drive…
(But then, I don’t really know how long 100k write/erase cycles would last me.)

I did some research on this Ace and it seems that this is not a issue anymore with the new SSD disks.

For example, a test conducted with a 64 GB SSD with 2.000.000 write cycles had the result that it would take 51 years of writing data on that disk in full speed before it would die.

Most Solid State Disks have between 1000000 and 5000000 write cycles nowadays.

Below is a short video by Samsung comparing Solid State Disk and HDD performance.

Solid State ‘Disk’ is a misnomer - there is no disk. USB ‘thumb’ drives are not labeled as disks.

(I once had to explain to my kid why I say ‘_roll_ down your window’ in a car with electric windows…)

Solid State Drive perhaps?

Thanks Martin, that’s great to know!

Bit like “Drawing” the curtains Andrew?

Where did my comments on this go?

They are back up !

BTW, your comments are always ending in the moderation queue, one way to stop this would be if you would register an account at ghacks. Registered users get lots of good karma when posting comments ;)

Thanks, Martin. I wonder what happened there…

As for registering a gHacks account, I must be blind; I can’t find a registration link or form… !?
