32gb Microsd Class 10?

[Mark In STL]

I'm looking at the PNY 32gb class 10 card and wondered if anyone has tried that or another class 10 microsd in the photon?

pretty good price. the brand i ordered from here is a 16gb. works fine for me

I have the 32GB PNY class 10, got it at BestBuy last week for 69.99, went on sale Sunday for 59.99, and I had 10.00 in reward zone certs, so I ended up getting it for 49.99 in the end.

I'd purchased two others (some generic POS, and a "SanDisk") off eBay, both were duds, but I got refunded immediately, thankfully.

Dotto.
I just picked up a 32gb Class 10s from Best Buy.

I moved all the data from my 8GB micro over to the mopho internal SD. Intalled the 32GB , formatted the 32gb with the phone. Then moved the data off the internal to the new SD. Yes, there was a noticable speed difference in transfering my data.

I'm going to be purchasing one for my Samsung Epic Touch 4G. Class 10 is necessary for 1080p HD Video. Good luck

Don't buy class 10 cards for use in phones. The random access times will cause the phone to lock up once you have a sufficient number of media files on it.

And as far as class 10 being "necessary" for 1080p recording, I find that very, very doubtful. Check the file size of the videos and I guarantee you they will come in under 4 MB/s (class 4). Bitrate has a larger influence on file size than resolution.

Read this.

I have a sandisk 16gb class 10 in my photon and it works really well and is quite fast. I have no issues so far and its almost full. Ill be buying a 32gb class 10 very soon.

 

[Snow02]

It's just not necessary, and will be slower for many things, at best. Primarily, gallery loading and music player library aggregation. At worst, it will cause lockups.

But by all means, do what you're going to do. I'm just sharing my personal experience and trying to save others from making poor, uninformed buying decisions.

Eh. I agree Snow02 that class 10 is overkill for cell phones although I'm runnin a Patriot 16GB class 10 SD card. I got it on amazon cheaper than an 8GB class 6, so to me, that was a bargain. But there had to be a problem with your SD card for it to slow your stuff down like that. As long as it is formatted in the phone and is a good card with no bad sectors, a class 10 should perform as good or better than any class 4 or 6 card. Still though, anything above class 6 is a moot point to me.

 

[Snow02]

Not true. The random access performance is sacrificed on those cards to obtain the higher sequential speeds. The problem on Android phones is primarily the media scanner that runs on every boot, when new media files are detected, and at other times. If you have a sufficiently large library of images or, in my case, music, the phone will completely lock up.

The same problem was seen with windows 7 phones when they released and people tried to add sd cards to the ones that had a slot. Those cards with low random access performance would cause slowdowns and freezes due to the way a phone utilizes the card vs. something like a camera or camcorder.

This isn't to say every single class 10 card will have problems, or even every person with X model card will, but many will. Especially those with 32 GB cards. Smaller capacities may not see as much of an issue due to not being able to hit a critical point because there's not enough storage to do so.

Again, this is just a fair warning. I don't have anything else to say on the matter.

So your recommendation on class would be??

So your recommendation on class would be??

Class 4.

I don't store music on my phone because I use audiogalaxy and stream it. I have over 100GB worth of music and picking and sorting music I want to listen to on my phone is a PITA!! This way, i have it all at the tip of my hands...er...fingers.

I do however, take alot of pics. I have 300 pics and 26 videos ( 1-5 minutes long) and my phone breezes through them without hiccups/slowdowns/freezes/internal bleeding and whatnot. I understand about random access times as I am a system builder that builds around speed and performance and not always GB's when it comes to my hard drives. But if you have installed a SDHC and it borks your access to your files, then there is something wrong (possibly bad sectors) with that card. Random access times between cards are measured in ms = miliseconds and the difference between the two are nill.

Wrong about win7 and slow access with SDHC cards. It wasn't that the performance of cards causing issues, it was that win7 OS wasn't coded to use an SD card in the first place. That is the way microshaft designed it but manufacturers added the slots anyways. It wasn't until microshaft outed an OTA to utilize external SD cards (and certified them) that people saw substantial gains in performance.

That's all I'm saying about this.

 

[Snow02]

I guess I should have said throughput. I thought it went without saying that the class doesn't affect access time.

And 300 images is a pretty miniscule number. It's not surprising you've seen no problems.
