SD card on the N66U

[srinivasvaradaraj]

Just wondering if anyone has used the built in SD card slot for any purpose, storing media, saving configuration, applications, swap, commands and service etc. I was also thinking that the sdcard could also be a viable extension to the limited NVRAM.

Settings can only be stored in nvram. Beside, the nvram issue has been fixed with build 220, which extends to the full 64 KB - more than enough for storing your settings.

The internal sdcard slot works just like if you were using a USB disk, with the same usefulness and limitations.

I am running optware on it i use it as swap ( NOTE : you don't need swap haha an it is certainly not recommended for flash storage it can wear out quickly )
I store my configuration backup files there made with the router UI, i store my VPN certificates on it.
Use it as a backup for whole firmwares.
NVRAM yeah well its what merlin said there is more then enought with merlin-wrt so.....

I mounted a microsd card 32gb class10 Adata formatted ext3 and it's quite ok, the reading speed is 10-12 mb/s but writte speed is very low, like 1 mb/s and is pausing for 4-5 seconds, so I can't use it for media playing
Maybe the built in Multi Flash Reader has this speed limitations

Can I use the SD card exactly the same way as USB disk can be used, like FTP/Samba/DLNA/Off-PC Download etc?

Not through the web interface, no. The router only displays USB devices, anything involving the sdcard has to be done manually through telnet/ssh.

Quick question, how do I ssh? I'm running stock firmware.

You can't. Stock only supports telnet, which can be enabled on the Administration -> System page.

Witch CL class i prefer to buy a new SDCARD? THX

 

[RMerlin]

Class 10 is the way to go these days. No point in buying a slower Class 6 just to save 2-5$.

 

[Fab30]

yes, but i have in my phone CL6 and want to buy CL10. But i dont know witch CL i put in router and phone... I want use in router swap memory...

Just purchase the Class 10 card. Your phone can use Class 10, but it may not achieve the full speed a Class 10 can provide. Same thing for the router.

Class 10 is just a speed rating, it's backwards compatible with devices that cannot use the full speed of the card.

I don't think you will see difference because I had an Adata 32Gb Class10 MicroSd and the speed was very poor, at maximum 1 Mbit/s.
You may use the MicroSd card only for some scripts, conf. or logs, don't expect to download torrents or to run some webserver on it.

Did the sd card speed improve with recent firmware or is it still the same?
