Re: n800, SD, SDHC, and storage
 

I just received my 8GB Class 4 SDHC Patriot card today and did run some quick speed test: I just copied a 327MB file from PC to the card mounted on N800, and back to PC.

The write speed was 3119kB/sec.

The read speed was 12596kB/sec.

These were taken with a stopwatch so some error margin is expected...

It looks like the Class 4 is being utilized with N800. Luckily I did not go and get the cheapest Class 2 card. :D

Re: n800, SD, SDHC, and storage
 

lol like Milhouse did.

Re: n800, SD, SDHC, and storage
 

Those read speeds are pretty similar to my Class 2 to be honest (I'd wager identical once you eliminate the variance introduced by the stopwatch timing) and the write speed I observed (6.4Mb/s) is significantly better than the Class 4 card.

All in all, I'm very happy with a cheap Class 2 device in my N800 thanks euchprof - but feel free to blow your cash on a Class 4 if you think it justified! :) I certainly don't think it is - the only benefit of Class 4 over Class 2 is when using the card in a PC card reader and performing bulk transfers where you should see improved write performance.

Re: n800, SD, SDHC, and storage
 

I didn't expect much difference in read speed, but wanted to make sure the write speed is reasonable. The Class 4 was only $5 more expensive than a Class 2 thus it was almost no brainer... :rolleyes:

Re: n800, SD, SDHC, and storage
 

In that case at $5 difference, fair enough - you can't argue with that! :)

Re: n800, SD, SDHC, and storage
 

While at it... anybody has any suggestions about PC card reader? Are all/any SDHC compatible USB card readers able to utilize Class 4 or even 6 speeds? How about bigger cards than 8GB?

In Ebay I see some but suspiciously they seem to limit up to 8GB size and talk about supporting 150X max speed and/or Class 2... :confused:

Maybe I need to search some Brand Name products and see if they publish specifications where these are defined properly...

Re: n800, SD, SDHC, and storage
 

a standard SD card reader doesnt seem to read SDHC. i got sucked into buying a 4GB SDHC card at CompUSA when i got my n800, from SanDisk and it came with a usb-2-sdhc reader. it ran $129 for the card, but the reader makes up for the ghastly price.

you can connect the n800 to a pc via usb, and read any card that is mounted in the n800.

Re: n800, SD, SDHC, and storage
 

Also, not all SD readers will read non-HC 4 GB cards. I have two that work normally in my N800, but only the built-in card reader in my pc recognizes them. A second, USB reader keeps insisting there's nothing there.

Fortunately, my cards also came with little USB readers; they're now essentially USB flashdrives with the low-capacity cards I've been accumulating over the years (well -- months...).

Re: n800, SD, SDHC, and storage
 

Replying to my own post... jpj did test multiple different cards using SimpleTech Bonzai USB 2.0 reader. In those results the Patriot 8GB Class 4 card (that I have) did get over 5MB/sec write speed, thus seem a good choice? It is also pretty cheap... :cool:

I think I'm going to get that one...

Re: n800, SD, SDHC, and storage
 

Need help, maybe i do something wrong.
I want to use with n800 Kingston 4Gb SDHC.
I'm trying to patch my n800 with sdhc kernel patch from device itself, but after string "./kernel_flasher/kernel_flash sdhc.bin" it asks "Are you ready to flash? (yes/no)" and then message appears:
"Nothing flashed.
Cleaning up... done."
After reboot n800 can't find card.
Sorry for terrible English.
