CF card vs Hard Drive on Intel platform

This week I had to throw a CF card with an L4 licence in the bin. It’s quite a process getting a replacement licence and it’s something I don’t want to have to do again.

The machine in question ROS ver 4.3, Dude ver 3.4 and User Manager ver 3.x

I suspect it’s all the writing to disc that Dude and User Manager do that led to the untimely death of the CF card.

So, I was wondering how I can go about getting Dude and User Manager to write their data to a hard drive rather than to the CF card.

Any advice would be appreciated.

Thank you.

That is possible, take a look at “Stores” in winbox. You can add disks there and use it as storage for user manager. I’m not sure about dude, but that is probably also possible.

yes all in stores. You should use a better CF card. Most will only run 100,000 writes if that. The PoweRouters (www.mikrotikrouter.com) use industrial cards designed for over 3million writes.

@gmsmstr,

Which ones do you use?

Sorry can’t tell ya. But I can tell you that there is an extensive amount of time testing and retesting cards using both acutal production units and simulated read/writes and they are NOT your normal 25 buck cards.

basically anything you get off the shelf isn’t made to last in a router.

I can say trenscends DO NOT like MT!

I can confirm this with regarding to microSD and the RB433AH.

There CF and SSD drives stink! MT does not like them for any reason it seams. and Cisco CF cards, WATCH OUT!!

Dennis,

I’ve been thinking of this.

What do you think?

you dont wanna use a microdrive… it has moving parts.

It’s also used.


While Ebay is an excellent source for many items, be very careful when buying memory cards though them. There are apparently lots and lots of fake memory cards being sold there. The cards may not be made by the manufacturer advertised, they may not have the advertised capacity and they may not have the advertised speed.

There are companies in China (and maybe elsewhere) who will put any label on a card you want if you buy from them in bulk. Some resellers do just that, buying off-brand, low capacity, low speed cards and putting name-brand, high capacity, high speed labels on them.

You may be OK buying from major retailers, but if you buy a cheap card from a dealer in the far east, you are gambling on getting what you expect, and the odds are not particularly in your favor. Be warned.
