Good price for a micro sd 16GB card.

Certainly can't find any better on all the usual sites. Free delivery as always and a solid brand name. Class 4 which is all you need for a phone really.

I NEED a 32gb class 10 for my nexus one

Original Poster

Koocha - Can the hardware subsystem on a phone really saturate the speed of a Class 10?

Class 4 is 4MB/s which is 32Mb/s, which is just shy of the absolute maximum specification for Bluray (good luck finding a commercial film with that bitrate)

If you've seen some good write-up of Class 10 cards and the real-world performance difference then drop a link because I'd honestly enjoy reading it. (not trying to be sarcy here - it would actually be v interesting)

Search as usual is pants on HUKD so I didn't see this, hence my post. Surely worth a repost though a month down the line.

My Desire can 'outrun' a class 6 card when recording 720p.

Isn't it better waiting for the class 10 @17.99?

Not quite.
Class 4 is minimum 4MB/S

Good to see someone else who doesn't buy into the marketing BS

Are Lexar any good?? I was looking at the 16gb SDHC on play for my camera but wondered if i should stick with the sandisk 8gb at about £9.

@BlueDan - I have a work Desire. It has a class 2 card in. Video recording on the highest settings works fine. Check out your memory card directly on a PC - probably not doing anywhere near the speed it should. There is no other reason for your issue other than a card not working to the standards it claims.

@Williamj1 - Not sure what retailer you're talking about. Depends on your purpose I guess. For me the £4 is better spent on a cheap bottle of plonk.

@gizmouk - Indeed. Not sure what else to say on the matter really :-/

@retrogeezer - Lexar have been around for years. They do some really speedy thumb drives as well.

cheers stanglish, the 16gb lexar is a class 4 at £12.99 and the sandisk or transcend 8gb are around £9 at the moment but class 4 seems quick enough. Mind you, 8gb is plenty big enough too....decisions, decisions!

Or possibly other apps making use of it, or keeping the phone busy otherwise, something I've been meaning to look into.

@retrogeezer There's a £7 8GB one floating around here as well. For me, because I quite like using my phone as an MP3 player 16GB is nice. Just take the punt on one :-)

@BlueDan Yep, perhaps so. Sure there's something on the market that could assist. If it's rooted you could try iostat/iotop

class 4, 6, 8 or 10 refers to WRITE speeds.

how many MB/Mb a sec do you think 720p is.

LOL

Great point. well made. You'll likely get 3x the read speed out of your SD.

The 2.3 OTA Desire users are meant to be getting will probably be a good excuse to do a factory reset

It shouldn't be an issue with the overall write speed or 720p encoding (meant to be done in HW), more likely it being busy with other apps running from SD.

Would be handy if the OS would suspend all other apps while recording video tbh.

Also forgot to add before, it'll work fine most of the time, then during playback it'll skip a couple of frames (and in the same place when played back on another device).

tbh im not sure bitrate of a movie is in totallycomparable to the class.
class is based on writing sequentially - ie copying over a premade movie.
but if you are recording then surely you are creating a file and adding to it incrementally?
smaller writes are slower so an overall faster card would help offset any problems?

sure i saif this before but noone has ever confirmed or denied it but it seems 'sensible' to me.
