Most CF have a limited number of writes that they will tolerate. That number has been going up as the technology matures, but I would still expect a regular HD to tolerate more RW cycles.

The same issue exists with SSD, but the better ones will recognize when a cell is reaching its life limit, and have alternate cell locations to switch to (active sparing).

Hi Josh,

wondering which one has a better MTBF with R/W access. I was wondering why the compactflash dies, it was not for the temperature because it was in a PowerRouter so the other option is that it died because of the R/W operations

So I was wondering if a HD would last longer simply because it is assumed that it will do R/W operations all the time.

My worry is if the CompactFlash will live forever or not.

Also: in what I got I found a normal CompactFlash, I used the Sandisk Ultra in the past in the outdoor and we got no issue in the past.

By the way: I lost the routeros that was installed/shipped with the powerRouter I am not sure I can recover the license.. :/
Anybody has a clue regaring that?

Thank you

CompactFlash.  No moving parts.  Why get a mechanical disk?

Hi All

my PowerRouter stopped working and after checking, I realized the problem
is that the compact flash brutally died.

So now I have to take a decision on what I should use as storage. Now
considering that the PowerRouter has also the possibility to store data on
a 2.5" HD, I was wondering which one is the best in terms of MTBF (and
routeros stability).... CompactFlash or HD?

Let me know what you think

Regards
Paolo
