SDHC card is SLOW

I've got an 8gb class 6 SDHC in my pro, works great, for the most part. It's the 8gb card from newegg. It's supposed to be extremely fast, but I'm seeing the opposite.

Using the stock 1gb card that comes with the phone, I had about 200mb of stuff on it, and had enough space on internal storage, so I copied everything off... it was going at about 1700-1800 kb/sec... Not bad for the stock card.

I put in the new class 6 card, expecting better speeds. I copy back all ofmy files and what do I get?

120-140 kb/sec.

File transfers between internal storage and the card (both directions) are painfully slow. It took AGES to copy the files back.

It has continued to be slow, I tried the SD card tune up located in bigdiesel's signature... but it made zero difference. The card is so slow it's practically un-usable.

On the other side, if I enable disk mode on the phone, and copy files over USB, it's fast! 2000kb/sec is about what I see. I know the card is capable of faster, but the phone itself seems to have issues with data transfer speed over USB faster than that. I read that some place and they compared it to the blackberry storm which made 12mb/sec.

So, any reasons for the card to be so horribly slow when moving files between internal storage (or downloading from opera, or anything else for that matter).

Edit: It's slow on both the stock ROM, and Dream's ROM which I'm using right now. Was slow on Juggalo's ROM too (.05B)

I got the same Newegg crd running on stock, and I do not notice any slow transfer , I have bout 3-4GB on it, runs ok. Are you currently stock?

I have Dream's ROM installed right now, I have not tried reapplying the SD card tweaks, but they didn't make any difference for me anyway. I have no clue what it is, because USB transfers to the card are as fast as they should be, but transferring to and from the card via anything on the phone itself is extremely painful... it was like this on my old TP I sent back and my current one.

Shadow , what are you using to transfer data over? just copy/paste with stock file explorer? I am thinking may be use Reso explorer and see whatcha get, when I transfer anything from to memory to SD , I do not even notice it man...ihst is fast.

Yeah, I've been using Resco explorer, it gives me the speed of the transfer. The stock file explorer sucks, especially when you want to modify manila files

An update to this thread finally... My card has started being fast again. A friend needed me to copy some files from his card to a pc so I did that, tested a copy from it (it was an 8gb class 4) and file transfers were fast. I thought I had a defective card but I put i6 backin and tried to copy a file and it copies fast now. The "fix" seemed to be remove it and put it back in again - something I havent sone since I got the card. Just something to keep in mind.

Really? That simple? Wow. Wonder if the SD tuneup would make a diff now?

You're lucky, going into Disk mode doesn't make my card transfer any faster

[orlandojumpoff]

im wondering if the hiccup you experienced is due to the brand of the card? at least it's working for you now...

I have the same card working well, so brand aint the problemo man
