Best microSD? What class should I go for?

[jkoljo]

I think I will buy this one: http://www.dealextreme.com/details.dx/sku.44517

It is a 16 GB Class 6 card, and it seems to be "genuine";
Test finished without errors.
Write Speed Average: 9.12 MB/s
Read Speed Average: 18.9 MB/s

ive also researched abit about micosd's and correct me if im wrong, the classes only affect the writing speed and not the reading speed? so why get a high class? is it because you just want to transfer files faster?( not meant to offend im seriously asking because im actually considering what sd's to get).You can get a 16gb class 6+ and you can almost get a 32gb class 2... sooo yeah.

 

[jkoljo]

Yeah but of course the card is faster overall if write speed becomes faster.

Whatever you do, DO NOT purchase your cards from Moby Memory.

I purchased one of their 32GB Sandisk MicroSD Cards and paid by PayPal.
PayPal took the money immediately but Moby Memory never sent any confirmation that they had processed the order.
I then sent them email after email which they failed to reply to.

I then sent them a message informing them unless they replied and sorted it I would contact PayPay to raise a dispute & post a review on TrustPilot.com
They then replied and gave me a processed number which took them a week to release.
The order form said it went First Class but not recorded despite paying for it.

Guess what... It never came and now they are back to their usual routine in not bothering to reply to my email messages.

I ordered The Kingston 16Gb class 10.
I will let you know when I try it

 

[jkoljo]

Yeah, I can recommend Kingston cards! My card is 8 GB Class 4, and it performs like a Class 10

Test finished without errors.
Writing speed: 10.1 MByte/s
Reading speed: 18.0 MByte/s

Faster is better

The card that comes with the DHD is a Samsung 8Gb class 2.

However this card failed - likely just a faulty card but it didn't give me much confidence.

I swapped it for a Transcend 8gb class 6 card I had kicking about which works flawlessly but I had already ordered another card from Amazon in anticipation of my phone arriving, which is a Class 10 Kingmax 8Gb card.

Now I know what you're thinking but I bought a class 10 to make it easier to transfer files to and from the PC. When I back up the new card it does take considerably less time to transfer the data to my laptop with the new card.

I believe a class 2 is just too minimum spec for this device and bearing in mind card prices are cheap now I would simply recommend the fastest card for your budget, if only for the reasons I have stated.

Is this with the card in a reader or with the card inside the phone via USB cable?

The bundled class 2 card only write at 2MB/s when in the phone but around 4.5MB/s when in a card reader. A higher class card will only be worth it if you remove the card from the phone to copy files. And how will that affect the phone, should you always unmount the card first?

If the DHD is anything like previous HTC WinMo devices the internal card transfer speed from RAM were poor. Putting a anything above class 2 made no difference to perfomance. So users hoping it would improve their video recording or speed up photo taking may see no improvement.

Perhaps someone who has more than one card with different classes benchmark the cards when inside the phone if an Andriod app exists.

What I tend to do is remove the card and stick it in a card reader on my laptop. I can then back the full card up once a month and also occasionally transfer music/pics to the card. It makes the whole process pretty quick.

It must be said though I do notice a difference in speed when transferring using a USB cable (ie the phone is a mass storage device) so it's still worth investing in a faster card, particularly as they are cheap enough for 8Gb cards which are probably ample for most users.

The DHD has enough horsepower to run on-the-fly encryption.
You can achieve this quite easily:
What you need to do, is basically build static copies of lvm, device-mapper and cryptsetup.
Add vgchange -ay, and cryptsetup luksOpen to initrd just before mount.
An easy way to realise key reading is to save your key on your microsd card (this of course implies that your sdcard is mounted earlier), and make cryptsetup read from it:
cryptsetup luksOpen /dev/your_vol/your_lab some_id < /mnt/sdcard/my_key.txt

it only makes sense to encrypt /data/data, /data/misc and /data/system, of course.
You can always encrypt the whole /data if you want.

The only problem would be to fit the static binaries into your initrd (you can build some of them with busybox and integrate it).

That's it.

I'll be waiting on your review. I'm trying to figure out if I should get a 16gb class 10 or a 32gb class 6, they are both more or less the same price.

When do you expect to receive your memory card?
Thanks!

I also found out that there's an Android app called MyStash which will encrypt individual files, could come in handy. I'd still prefer on-the-fly encryption, but hey.

SecretVaultpro , it's in the market.
