N70 Memory card

slitchfield, I've a 512MB Kingston in my N70 and video is smooth...not jerky at all. It comes with a lifetime warranty too and I'm happy with it. Although I haven't tested read/write rates. Didn't think your's should be slow as that...let's see what other 1GB owners' performance.

Jon

What I'm suspecting is that Kingston is slower in their cards than those from other manufacturers, and also that the 1GB cards, with their slightly larger file tables, are slightly slower to access by necessity. Add the two factors and you might get the results I saw.

What we really need though is lots more data from other N70 owners! I'll put up a pointer to this thread on the AAS front page.

I'm using a 1GB takeMS card for my N70 and it works fine...
But something is strange in this card, it has 13 pin in 2 lines intstead of 7 in 1 line...
even so the card works properly...

I've been using Kingston 512MB MMCMobile on my N6630 (the latest firmware v.6.03.08) for about 2 months with absolutely NO PROBLEMS... :icon14: I can also read/write that perfectly with my card reader.

Can you both do a simple benchmark? Copy and Paste or Move a largish file from Internal to expansion card and then tell us the number of MB/sec, approximately.

A 1gig card is �25.99. So very well priced, and a swift service, so i dont know about the best, but they are certainly the best ive come across 😊

MobyMemory

Ive had no problems yet, however i would reccomend getting a mem card reader from somewhere, as tranferring files to my phone through the data cable is painfully slow, around 30 secs per MB.

I'll second that. I bought two 1Gb's from MobyMemory - one for my N70 & one for the wife's 6680. Both work flawlessly with music, video & TomTom.

It's quite hard to measure any transfer speeds as I have only about 2,5MB free flash on my N6630. I think that it would need about 5 to 10 MB file to tell any difference on speeds...

=)juha

is the speed in the handy so important? i have no problems with my 512mb mmcmobile card and my 6630 and my cardreader can write on it with 8mb/s. only the access time is too long. i can transfer one 20mb file faster than 50 small .txt files.

I have an N70 and am using a 1gb atp. It works flawlessly. On an unrelated note, this forum form looks bad on my n70 using opera. Im writing this from it. The form is long and skinny. On topic, 1gb atp works perfectly.

Get one of these. Smallest and cheapest card reader, best way to carry a spare card, turns your card into a USB flash drive.

I had my N70 for about a month, and a week back, obtained a bargain-priced (~18� or so after conversion from my currency), Kingston's 1GB DV-RS-MMC Mobile card.

I formatted the card with my card reader (as FAT16) and N70 said it's corrupted. So, I formatted the card with the phone. And it's been fine since.

So far, there's no issues of unredable/hangups/missing files/apps on my phone yet.

However, performance is medicore. Pasting my 8mb MP3 from the card into the phone memory takes about 6 seconds (that's a little over 1.2mb/sec) - I'm not sure if this is good or bad?

Transferring files to and fro the card with a card reader is fast though, around the same speed as my USB FlashDrive.

"into the phone memory" - we're mainly talking about WRITE performance here - can you possibly give me the speed at pasting the same file back onto the card?

I have a 512 Mb card and it ruined my phone. the gallery freezes all the time, and the video freezes too. First i thought it was the phone with bugs, but after a while i understood it was a mmc problem... What a waste of money...

Steve,
I will be more than happy to provide actual write/read speeds if you will tell me how, or what program, or what... I just dont know where or how to get the "speed" info... Let me know and will test, mike

-never mind, just read the post and realized how to do it... Copied a 7mb mp3 from root c to root e and it took aproximately 8 seconds. so thats just under 1mb/sec write to card.

My first post on the forum...

Using a 1Gb Dane-Elec MMCmobile card with no problems at all (lots of music, eBooks, data & apps).

Copied a 11MB PDF document from C:\ to E:\ in 11.2 seconds, so again about 1mbps. Using a USB flash drive I get MUCH better performance (transferred about 400MB of oggs in one go - didn't take too long. However, converting 800MB of MP3s into OGGs took almost forever!!).

The MMCmobile spec states a *minimum* read/write speed of 2.4MB/s - cards have to be faster than this to be called MMCmobile, so I guess the lower performance is to do with the RAM<->MMC interface on the N70.
See page 11 (13) at the 'MMCmobile' spec: http://www.mmca.org/compliance/buy_spec/MMCA_System_SummaryV41.pdf

Thanks. That's roughly what I see from my US TECH card, perhaps confirming that the N70's max write rate is around 1MB/s. And puts the 0.3MB/s write rate of the Kingston 1Gb card into perspective!

Any others who can contribute data?

Could firmware be an issue here? I'm using an N70 - F/W: V 2.0537.1.7, 18-09-05, RM-84. I also have the Orange Talk Now service activated (This is Orange's version of Nokia's Push To Talk, PTT, walkietalkie type service) and notice that the Talk Now app is always visible in the app list. Anyways, I use a MobyMemory branded 1GB MMCMobile card and it's been working perfectly since I got it in Dec '05. I seem to get results twice as slow as everyone else so far :icon13: :frown:

I got the following results using FExplorer V1.15 and an MP3 file of 10.205MB:

Copying from E: to C: (from MMC to phone memory): 27s equivalent to 0.38MB/s

Copying from C: to E: (from phone memory to MMC): 20s equivalent to 0.51MB/s

slitchfield wrote:... Video recording on the N70 to card was next to impossible, with horribly jerky capture. I went back to my US TECH 512MB card and all was fine again.

I strongly suspect, as mentioned by others, that the slow access speeds are also responsible for occasional breakdowns in the integration of apps into the Menu system...

I've never lost an app in the manner that you describe and video recording even on the highest setting has been fine when I've taken them, infact I would say the N70 is better at taking vids than it is at still images.

:icon4: I just had another thought... I run Symantec Mobile Security :redface: I'll re-run the test with it switched off. See what I find... No difference what-so-ever.

Only other relevant info I can think of, I have 15MB free of phone memory and 520MB free memory on the card.

Hmm I feel a phone format coming on. Heh or maybe a firmware upgrade.

I just received a new 1G Adata card which is much better than my previous 512M kingston one.

Video is perfect and I don't have any longer problems with TomTom and POI ! 😊

I am definitely sure that write/read speeds are really important if you want to use your N70 correctly

Adata specs are 100x high speed MMC 4.0 standard which was the minimum required by tomtom to have its software working properly.

Gallery is also speedier

I *think* that MMC Mobile is a standard form of DV RS-MMC that has extra pins and has the potential to be faster. But you can't always guarantee it. A lot seems to depend on the manufacturer involved.

Can anyone else shed light on this issue?

Steve

well the defualt card that came with my n70 had these extra pins & is labeled dv rs however the card which i bought for my 6630 about a yr ago is aslo labbeld dv rs but doesnt have the extra pins.
moby memory sell the ones with the extra pins at a higher cost. they lable them as dv rs & the standard ones as mmc mobile

Regarding MMC performance, I just wanted to check if it was possible or even advisable to defrag a MMCmobile card (using a PC & card-reader). I'd asume that this would result in somewhat increased performance especially given the access latency of the N70.
(sorry for posting this again, earlier post in another thread got no response :frown: )

might increase the speed for a while but seasm rather pointless. sicne the mmc is l ike a usb key would you defrag a usb key?no, sicen it would just get fragmented agian after a few transfers. defrag is better suited to pernament hdd since they will usally hold stuff for quite a long time.uslly with our mmc we put stuff on then delete it once weve backed it up

I have used a Kingston 1Gb card for about two weeks now, I have not seen any problems at all. copy speed appear to be around .2-0.3 Mbps when copying from C: to E:

I have not noticed any problems playing back recorded videos - apart from the expected 15fps stuttering.

I do play back a lot of pre-recorded movies (Smartmovie at 160 kbps), no problems

It may be slower than most cards, but at about 23 GBP, it was cheap.

Oh well, here I was going to buy a Kingston 1GB MMCmobile, and now I hear everywhere it's a bad idea =/

OK then, reading through this page I can conclude that the good 1GB RS-DV-MMC are:

  • ATP
  • Adata
  • MobyMemory
  • Dane-Elec

Is that right? Is there any other I could trust?
It's pretty hard for me to find any of these cards here in Brazil, so if you could find a trustable site that would ship one of the trustable brands of RS-DV-MMCs internationally to Brazil I'd appreciate it.

[SIZE="4"]EDIT[/SIZE]

I found a couple of sellers that are selling these Adata cards. Do you think those announced Adata cards would be a good deal? The guys selling have pretty high eBay scores, and they do ship worldwide.

You can buy Adata cards securely from flashman on ebay. I already bought quite a few things from this shop, very good products, very good services, prompt delivery, never a single problem.

I strongly suggest Adata cards, with my 9500 and my N70 they always proved to be the quickest and safest on the long term.

As I said, the 100x 1G for my N70 allowed my phone to be much speedier and without any problems with TomTom POI (always crashing before with the old card)

Thanks bluestar! Could you do that test that was being mentioned early before in this topic to see if your card's writing transfer rate is 1mb/s as expected?

I bought Adata from Flashman on ebay.

Well, the problem is still there. The jerky video recording is still there.

It is fixed by immediately formatting the mmc, after which it records rather perfectly at a perfect framerate. But after a while, after I've filled the card with some amount of data, its video recording becomes jerky again.

Can somebody PLEASE find a fix to this problem? It would be great in Nokia gets to know about this and releases an update or something.

By the way, is this any case of a messed up N70? Can i take my phone to a service center with this reason and get the phone replaced or something????

Guys, I found this :

Now, if you've been following the conversation in many of the N90 forums around the web, you'll have seen that a common 'problem' on the N70 and N90 is jerky video capture, with the culprit usually being sub-standard memory cards. The N70 and N90 capture video at 352 by 288 pixels, at 15 frames per second, saving data at around 4MB per minute. The N93 will be capturing four times as many pixels at twice the frame rate, with an estimated data rate of 20MB per minute. Sustaining this for long periods (minutes) with no holdups whatsoever is going to take some doing and cards such as SanDisk's new Ultra II cards are going to be needed if video really is to be captured at full resolution and rate. You have been warned - an older card or cheap eBay knock-off won't do here.

Wow. So ADATA cards from FLashman on ebay really AREN'T GOOD. I bought it, and the jerky video recording IS STILL THERE.

Someone, Somewhere, please point out a good, original, seller on ebay who sells the real stuff. It doesn't have to be Ebay, it can be any reliable site with international shipping. I want to get rid of this problem soon and quick.
