SDHC cards comparison review
 

While we are waiting on the SDHC card frying issue to be resolved by Nokia, I am keeping an eye on availability and pricing. There is a confusing plethora of choice but very little information on which to base a decision.

This review is very helpful, though there are a few omissions that could have been usefully included e.g. Transcend, Adata, Integral, etc. But the man is only human and a selection of 9 across a wide range of speeds and classes is still a good effort.

Re: SDHC cards comparison review
 

I just ordered an Adata 8GB SDHC card from NewEgg. I should have it by Tue/Wed. Some N800 owner posted a comment at NewEgg that this particular card, while Class 2, had speeds like a Class 6. That, coupled with price, was why I ordered that card. I hope I didn't make a mistake.

Is there some SD card speed testing program that runs on the Nokia?

Hi, can You tell how much does it cost for 8 gb card?

Re: SDHC cards comparison review
 

Under $70 w/shipping. Check NewEgg web site.

FWIW I have a 1gb Adata sd card doing sterling work on my Zaurus for over 2 years now.

It is interesting to see Delkin eFilm Pro not doing terribly well. ATP were unknown to me prior to this test and seem to be worth checking out.

Lexar and Corsair don't have an 8gb sdhc yet which makes me wonder.

Re: SDHC cards comparison review
 

I ran some benchmark tests on my new card. It seems that the card does indeed perform like a Class 6 card on write speeds (6MB/s minimum). Does anyone know what a Class 6 read speed should be?

Below are the results, using an internal USB multi-card reader in my PC.

I also noticed that when copying large video files, putting the SD card in my PC's card reader is about twice as fast as copying the same video to the Nokia via USB. Isn't the N800's USB port supposed to be USB 2? What is the bottleneck - the N800's USB port or its SD card hardware?

Re: SDHC cards comparison review
 

That's propably because the N800 stock kernel uses only 24MHz clock speed. With the SDHC kernel (or MMC kernel something for the latest firmware...) N800 can use 48MHz clock speed. This would make it about twice as fast. The higher speed SDHC cards should support 50MHz clock speed, and I believe most card readers do.

(Someone correct me if this is wrong...) :)

Re: SDHC cards comparison review
 

Is that higher clock used for everything or just the SDHC card transfer? If everything, I imagine that would suck more battery power. Other than the clock speed difference, what else is different between the official kernel and the one you mentioned? Where can I obtain it? Is is safe to use? If it blows up my N800, can I flash back to the official software?

Re: SDHC cards comparison review
 

I just bought a PQI 4GB SDHC card. When I insert it into the external slot, it doesn't show up in the File Manager. Is there a list of cards that don't work with the N800? I'm running the original firmware that came with the N800.

Re: SDHC cards comparison review
 

Early firmware didn't support SDHC cards only SD. So that might be your answer?

Check the About information in Control Panel for your firmware version.

Internal slot is picky.

My first one is kingston 8Gb class4.There is no problem to read and write data in interal and external slot. But the screen flashed every 3-4 second when I put it into internal slot and charge it.

Then I bought another one scandisk Utrl 2 4Gb clas 4 for the internal slot.It is no problem for now.

It said ,
Non-volatile solid-state; no moving parts maximizes battery power; data is not lost when power is turned off
Low battery consumption to maximize battery life in small portable devices
Operating shock rating of 2000Gs, equivalent to a 10' drop to the floor

Re: SDHC cards comparison review
 

I'm a new owner of an N800 and I bought 2 PQI 8gb cards from meritline (or was it supermediastore?). Anyway, they cost $35 each and I have had zero problems.

Re: SDHC cards comparison review
 

I was shopping recently ( end of December) for a place where I could buy a couple of different size cards for a good price. At the time it seemed to me that I could get a good price on one size at one place and then I had to go to yet another place to get a good price on another size. The other thing that seemed to be happening was that shipping seemed too expensive at most places. But I ended up finding a place called mwave.com that had good prices on most products and reasonable shipping costs. ( like the actual shipping costs rather than inflated.) So I paid $23 each for 4GB class 6 SDHC Transcend cards and $44 for an 8GB Transcend SDHC Class 6 card. I thought those were very good prices and the cards have been working fine.

For $90 plus shipping, 8Gb micro SD.

This works using a micro-to-mini adapter in my n810 (the micro to mini is NOT included).

A-DATA 16GB class 6 - 59.99$ http://www.newegg.com/Product/Produc...82E16820211245

orderd them 2 weeks ago for 74.99 :(

Re: SDHC cards comparison review
 

I just got an A-Data (from meritline) and it works in the N800 - I'm adding swap and ext2/3 partitions as I write this.

Re: SDHC cards comparison review
 

- ouch! got my two 16GB Adata class 6 cards at the US$59.99 price... they work great in my os2008 n800 - 32GB! w00t!

(of course, this time next year, a 16GB SDHC class 6 card will be US$29.95)
