Hello,
I recently bought an 8GB microSD, class 4 (it's all I can afford ). Tested it for write speeds (output is 6.2MB/s). I assume I'm not gypped or something and I got the real deal (bought it at a computer store). I was wondering if this is good enough for the x10 mini pro if ever app2sd works.
Also I would like to know what capacity/class your microSDs are (for statistical purposes)
Thanks!
Are you sure 6Mb /s ? then its class 6 ... I have a 2GB .... yes app2SD will work

Yup. tested it using H2testw...
I thought I can put a whole offline wikipedia in it. Turns out the whole English DB is 6 gigs... Not enough space left for music and pictures and maps...
What the class of the SD Card included with the phone?

I haven't tested yet (I already gave it away)
But I think it's class 4 or class 6. It can't be class 2 because it's waaay faster than 2mbps.
I got a 2GB class 4

kabayan!
I have the original 2GB with me. i researched it and i think its Class 4 Kingston.
Micro SDs have Class 2 to Class 10 (Class 10 as the highest, having minimum of 10mbps speed, 16GB and 32GB I think).
I've read somewhere that its recommended to have Class 10 MicroSD if you'll be using Apps2sd. but if your 8GB works fine, thats cool.
I dont want to root my phone so no Apps2sd for me though i really really need more space in my internal storage now.
Im hoping the rumors are true that X10 mini and mini pro (and of course, the big x10) would get Froyo updates on 2011. I think Froyo natively allows installation of apps in SD right?
I bought my 16GB mSD class2 2009 for my Samsung SGH-i900 Omnia.
Dropped and ruined the Omnia in a puddle of water in the spring of 2010. But both SIM-card and the 16GB memory card survived the water even if the Omnia didn't
Still using the 16GB card for both photos and music as well as for a few movies in the X10 Mini.
I don't know why a class2 that shouldn't read or write more than 2MB/s does both well over it's 2 MB/s limits in the computer.
The SIM-card was destroyed this January as my contract with Telenor expired.

I currently have a stock 8GB class 2 in the phone and i'm thinking of getting a class 6. I'm pretty much using 7 out of 8GB so i can manage it but it's getting rather close.
The 16GB one would cost me almost 60€ and that's a lot! The 8GB one would be only about 19€.
I didn't try ebay, maybe i could find something there. But given the price difference i think i'll stick with 8GB, what do you think?
The main reason i post here is to ask if there's going to be a NOTICEABLE difference in opening a gallery full of pictures, and picture saving time after taking a shot with the camera?
The HD recording is just a plus here, i just want the galery/shots taking to be faster. Anyone with experience?
thanks
EDIT: ok i've found this one on ebay and it has a USB reader so that i can still use my class 2 8gb as a usb stick so that's a money saver.
I've never had any experience with this company "Team", are their cards any good?

Well I bought it from eshop.gr and paid it 99 euros, it's 100% original but the phone itself can't handle faster chips, the difference is not that much, you might consider buying a 4 class which is by far cheaper!
i think i'll just get a class 6 8gb for 20$ and stick with that, that way i'll just use my old class 2 8gb in an adapter as a memory stick

Configure "app to SD" then you will notice the difference. For normal use, class 2 is more than enough.

for normal use, it sucks! i need to wait at least one minute for the gallery to open because of all my photos, isn't that because of a slow SD card? correct me if i'm wrong...
Be carefull when buying SD cards from Ebay. I bought an 8GB class 6 card once (no brand, from Hong Kong) and it turned out it's not really class 6 at all, more like class 2 or 4 (low transfer speeds). The class 6 card that came with my X10 is a true class 6 card (transfer speed of 6 MB/s).
I'm not saying all SD cards on Ebay are fake, but alot probably are (fake as in not the class they advertise).
heh, i already ordered one
it's from a top rated seller so i hope it'll be ok
thanks for the heads up
I have a class 6 16 gig, i did have a class 4 8 gig and i could not play need for speed as the game would freeze. now the game plays no problem with the class 6 card.
what does an SD card have anything to do with it?

the class reprezents the speed of your memory card
I bought a 32GB Kingston Class 4 and it keeps unmounting itself and overall lose contact with the phone but it works perfect in he PC.
I have done a 32GB filer verification so it's not a counterfeit 8GB in a 32GB disguise.
But I keep having trouble with it once it's in the phone.
It's a HTC Legend with BlaYo ROM
I have exactly the same micro SDHC (32 CB class4 Kingston) in a XPERIA X10 and it functions perfect. Try format with MiniToolPartitionWizard under Windows. Success!
I'm using a 16GB Class 10. Transferring songs are plainly drag and drop.
If you opt for speed over capacity, go for 16GB C10 instead. I'm using the Transcend one at 14MB/s writing speed. (priced at 33USD)
Well uh, why do you need 32GB for a phone?

I'm using one Transcend 16gb class 10 card, i can tell some things:
On the usb adapter it can WRITE at up to 16~20MB on linear writing and READ up to 22~25MB on linear reading.
This cards rocks, i had a sandisk 8gb class 6 mSD and will never regret this change.
This time i can get real HD recordings as before i would sometimes give me some small breaks when recording if for some reason anything tried to access the card at the same time.
By the way most class 6 cards record actually between 4~6MB!
I bought a Xperia Mini pro SK17i a few days back. It came with a 2GB memory card. I want to upgrade to larger space.
Please tell me should I go for 16GB or 32GB one. Will there be any problems? I mean any slowing down or hanging etc. Also tell me what class of microSD should I buy?
Im using a Class6,32G card on my mini,i think it's fast enough.
It matters how much space you need. Class 4 and above is fast enough for the XMP, not it is just your choice how much space you need . Im using Class 4, 32GB SD Card and I haven't got any slow or problem with loading my music or pictures.
I'm on a 16gb class 6, no problem at all.

Go for a 32 GB one if you think you'll be able to utilise the space. If you pick a class 6 or 10 card you really shouldn't have any speed problems. Obviously a higher class card is faster - class 10 FTW!
Micro SD Card Suggestion
Well 16Gb or 32GB is based on your requirements
My suggestion would be 16GBclass 4 or 16GBclass 6
I am using 16GBclass 6 on my SE Live With Walkman and it has no problem
for me
Class are based on their speeds
Class2 -->2Mbs
Class4 -->4Mbs
Class6 -->6Mbs
Class8 -->8Mbs
Class10 -->10Mbs
Use "Crystalbenchmark" to test the read/write speed of your cards
First check the read/write speed of your 2GB sd card that came with
your device and this help you to differentiate speeds of different class
types

These are only minimal speeds, these can be higher.
I have Class 4, Sandisk, 16GB, Write is 8.7 MB/s, Read 28.9 MB/s.
There's a thread on this subject somewhere here.
What you need to consider as well is access speed.
Higher class cards transfer faster, but to do so, data has to be accessedfirst, and that takes longer with class 10 than class 2 for example.
That means, if you are goinf to work a lot with larger files, it pays you to get a high class, if on the other hand, you are going to onstall apps to work with small files a lot, it will actually slow you down.
Edit:
I've found it, anybody interested should look at the tests results

Music just comes from speakers/headphones. No lag for me, so don't worry about the speed.
Says the person who has Class 4 16GB SDcard.
sorry i am a newbee..but could u tell me how to know whether the card is class 4 or 6 will it be written on memory card cover? or it depends on company which manufacture it?
It will be printed on card.(look for a big C numeral will be inside it)
Class 4 is sufficient. Class 6 is gud nd economical. Im using class 4 8gb, no issues

Well I got a 32GB San Disk Class 4 and...it's brilliant...the music library doesn't need any time to load...it's all ready...and after synching music, it only has to load what's changed (sounds simple, but not all devices are do that, trust me!) so I'm very happy with it...the bottleneck so to speak is now the Sony music app...it doesn't connect very well to Media Go. I'll save that moaning for the right thread lol
p.s. there are many threads on here about testing the diffferent class performance of SD cards and Class 4 San Disk was by far the best...other class 10s did not perform better reading and writing...they performed worse. Very happy with class 4. I got it on ebay for 23€ by the way, too expensive in the shops.
it depend on brand also. scandisk class 4 higher speed than other brand with the same class.

I'm with A-Data 16GB Class10 and the phone works perfect. I was trying with 32GB Class10, without to full them and the phone works with the same speed like 16GB card. I'm not sure if the card is more 80% full.
