Just wondering if anyone has done this? I had my sd card in a reader on my pc, moving some photos around... for craps and giggles, I decided to defrag the card. Wow! It is reading alot faster. I was having some lag, pulling up photos, movies, and documents, now it is lightning fast.
Just wanted to share.:thumbup::beer:

Basically a ssd or memory card does not need to be defraged because data is read in a different manner duo to not having moving parts which defragmentation has no impact on speed.
But i exprienced some speed problems while recording video on my nokia 5730xm and video got laggy which by defraging memory card the problem would b solved.
Anyway, Defragging these memories will reduce their lifetime very much.
But there is apps like android defrag or disk defragmenter on play store.

defragment is needed only for hdds with spindles(it moves to fetch your data). not required for ssd or sd cards as it dosent have one. having said that. i defraged my sd once in pc and strangely i felt things were much faster than before. o_0
Well...this was an old sd card that I had in a previous phone, and whenever I had it in my phone..the gallery and media player had terrible lag. Like I said..I just tried it, and was shocked at the result. Way faster.

It has more to do with the way the data read from the card is cached by the respective OS reading it than anything else. The data might appear fragged, but it's technically not, since all the sectors on an sd card are essentially equal, unlike a spindle drive.
Even i didn't believe this. But defragging SD Card surely helps. I guess defragging groups the data so it can be fetched easily.
just a question, ....isn't sqlite data base vacuuming a similar process?

I'm moving the data off my stock 2GB card to a SANdisk 8GB Class 4 card to gain more media performance.
I understand FAT32 is better than FAT16 in this respect...
In fact the Hero formatted the card as FAT32 so assume it prefers it
Now, copying to the card, my Mac is copying very very slowly, far slower than the stock FAT16 card did.
Is this normal ?
Well done a bit of testing and the Album app is waaay slower on my class 4 8GB card formatted as FAT32.
Images in grid view and filmstrip view pop up more or less instantly on the stock 2GB FAT16 card.
On the FAT32, they appear as grey boxes before being filled in one by one with the actual image.
Note.
I've cleared Album's cache and data to force a rebuild of thumbnails, that thats not the issue.

ive noticed this aswell as i got me gf a hero at the same time as i got mine but only got a 8gb sandisk micro sd cardfor myself.
Her album photos with about 20 photos in is sweet as but when i scroll thorugh mine also with about 20 photo's in i have to wait for the grey boxes... when i got my 8gb card tho i didnt format nothing just plugged it straight in and started using it. everything else seems a little faster though compared to hers
My 8GB card was used in a Nokia N85 before so I had the Hero format it for me.
Assuming this would prepare it for use correctly...
Gone back to the stock 2GB card and all is zooming along nicely again.
Are you sure this isn't a caching issue guys? It may be slow to load on the first time while all the thumbnails are generated, but should be snappy afterwards. I would however be worried abou transfer speed between the SDHC Card and Mac as that should definitely be faster than a class 2.
When I changed from a class 2 to a class 6 I would say my read/write speeds doubled (or just over), I seem to get about 6-7MB/s when writing to it.
Have you tried writing to it when not in the phone? That will probably give a slightly better (or more realistic) reading.
Its not caching, I already tried clearing the applications (Album) cache and allowed it re-create its thumbnails in grid view and filmstrip view.
Opened each album and waited while it created them all.
Restarted the Hero and then went back to Album.
Still very slow compared to the 2GB card. No idea what class this is as it doesn't appear to say (writing on the backside is almost too small to read).
Writing to the card via my Mac starts fairly quickly, slows down to a real crawl and then a few minutes later speeds up again.
Worked fine in the N85 and recorded and played back video at a much higher bandwidth than the Hero can do.
FAT 16's limit is 2GB. so if you want to use a larger card then 32 is the way to go.
http://en.wikipedia.org/wiki/File_Allocation_Table
Thx for the info...
The problem I am seeing though is that the FAT32 formatted card appears to be far slower than the FAT16 card.
i forgot to add in my previous post that backing up the data to my pc was very fast on both cards, the only slow down i get is with the album app, exactly the same as joemax.
apart form that everything else is faster than my gf's 2gb card.
im gonna try backing up my data and formatting the card as i never tried that the first time
will report back with any findings.
edit:
tried formatting but made no difference, is fine with just 8 photos on, but once you start going to 20+ you get the grey box syndrome, which only last for 2 seconds or so before they appear but ofcourse would be nice if it was ultra smooth. could be that our sandisk 8gb class 6 cards are fakes .. i got mine of amazon for £15. i wouldnt of thought so but you never know, as everything else on the phone is running sweet.
I formatted the 8GB card in the Hero and in the card reader plugged into my Mac...
No change is speed at all.
Album is definitely far slower on the 8GB class 4 SanDisk card.
I just bought a generic class 4, 8gb memory card and the lag was terrible took an age for anything to load, so i went and got a class 6, 8gb card and the speed is back up to what it was when it came with the 2gb card. I strongly suggest anyone not to buy anything but a class 6 card.
Thx. Will look out for one on my travels.
Anyone know what class card the Hero ships with ? Mine does not say, if it does the writing is far too small for my eyes to read.
Heya Joemax,
I think you're getting the same problems as quite a few others. It seems to be some kind of problem the Hero is having with certain cards.
The problem being that it does not create and store the thumbnails for the Album gallery. The folder is created but the files are not. We are currently trying to work out why this would be, but i'm sure it's some kind of SDHC incompatibility with current Hero ROMs.
I want to buy a micro sd card the same speed/class rating as the built in memory in my galaxy s2. Don't see any point in going higher class or speed, on the other hand I don't want to go lower. What class our speed rating of microsd should I therefore buy please. Thanks folks.
You won't ever get a sd card that will run as fast as the NAND/internal sd. So in essence, your goal will never be achieved. What you can do however, is change the external sd card reading speed/rate, so that the scanning will be much faster than stock. I don't remember where a guide can be found, but search it up, it was on the portal/news here once. Also i do not know if it will work with the GS2.

It's called SD-Booster. It will only allow you to modify your READ times. It also requires root access to be set on boot.
Thanks both for your replies, my phone is not rooted (lack of confidence in doing that re warranty etc just while its new)
On a slightly different tack, is there a speed rating of a micro sd which would not impede 1080p video playback on my SG2 , I download a lot of astronomy podcasts which are HQ for small details to be displayed, not too bothered about the time to save them onto the micro sdcard , but wouldnt want the micro sd card not to be able to supply the data fast enough back to the system for smooth play. I know I could keep most of them on the factory memory, but micro sd based playback would be useful too.
Hi everybody
I just got my phone yesterday and after inserting my class 2 16gb the phone asks me where i want to save pictures when taken with the camera. Any of you with performance "tests" regarding this so far?
Best regards

class 2 will defininitely not work with HD recording. correct me if im wrong. photo's are okay for that but if you will gonna load pictures in the gallery app i can guarantee you there will be some latency in loading thumbnails.

In your position I would save them on the internal card. As you probably know it will offer a faster transfer rate than the external SD card, especially as your sd card is class 2.
I doubt this will have an impact when taking single shots, but features like burst mode may suffer. Videos are very unlikely to work smoothly.
As your internal memory will have 16gb or more of space I dont see the downside. You can always use a file manager to copy files to the external card if problems arise.
If you are tempted by a faster SD card then this one seems to be universally regarded as the best. In case you are not sure about SD cards class system, an explanation can be found here.
Hello all,
Question for you guys/gals, i ordered the Z2 and expecting delivery today. I am now looking at microSD cards. I notice some inconsistency in the MicroSD card capacity from different sites. Anyone know if the 128 works with the Z2?
Sony's site: Expansion slot: microSD™ card, up to 64 GB (SDXC supported) Clicky
Phone Arena: microSD, microSDHC, microSDXC up to 128 GB Clicky
GSMArena: microSD, up to 128 GB Clicky
Thanks in advance!
It shoyld support it mate, I wouldn't worry about it

128 gb should be no problem
I got my wife a Z1 Compact and am (im)patiently waiting for my Z2 to arrive. I ordered a mess of the SanDisk 128GB cards when Amazon first got them in about 2 months ago. I've yet to put one in something and have it not work properly. Works perfect in the Z1 Compact, so I would think that there would be no issues with the Z2.
I should warn you however that the performance is pretty painful. Coming from SanDisk's 64GB extreme plus, the speed of something that just makes the cut to be a class 10 is a little disappointing. For me capacity comes before performance almost every time - my Go Pro probably being the lone exception.
Thanks all. Very much appreciate the responses.

I have a 128gb in my Z2, only got the phone yesterday, no problems so far
My 64GB card is showing up as a 64GB card but I'm yet to find a way to actually get anything onto it. The only way I got stuff on is when the phone's internal capacity was getting full (already! after one day!) and it offered to move stuff (movies, music, photos) to the SD card. It managed to yet none of my file manager software on the phone, or when connected directly to PC, or via WiFi File Explorer, or even when the card is directly in the PC with an adaptor, lets me put an actual file on it. I can create a new folder if I'm lucky, that's it.
It's a beautiful phone but the SD card is doing my head in. I've a Sony 64GB SDXC so it should work a treat... have I missed something? Like an option somewhere to actually allow writing data from the card by the user rather than just when the phone says it's okay?

That doesn't seem right.
So according to you I can't put music on my SD Card; I can record movies and photos on the phone onto the SD card but cannot transfer them to a PC, and I can't basically do ANYTHING with files on the SD card on my phone?
That doesn't sound right. What's the point of having an SD Card slot at all then? I thought the Kit Kat restrictions applies to apps, not general files. If you're right I'll have to change to another phone as that is a step backwards. It was SO easy on my Xperia S.
So far I've had to upload all my photos & movies I've taken since getting the Z2 to Dropbox and then download them on my PC from there, which is taking HOURS. I'm then going to format the card and see if that helps (I did not format it on insertion as it showed up OK and all seems well but my PC won't read it even in a reader).
This don't seem right. I'll update later (it will, as I said, be hours) with a solution to this in case anyone else is having the issue I'm having.

The restrictions that kitkat impose are that applications cannot write to anywhere on the sdcard and must use their own folder on an sdcard. Applications that have rootaccess are able to bypass this limitation including some pre-installed apps such as the camera, walkman and file commander application.
I have all my music and videos stored on my sd card and have no trouble accessing them and I copy them across in media-transfer mode via usb cable on my pc.
When you attach the sd card to your pc, are you doing it through your phone or via a card reader etc?
Situation has changed a little now - I can now view the card correctly on my PC.
It's because I'm stubbornly still on XP (I am NOT moving to Vista, 7 or 8 any time in the future!) so I needed an update to enable SDXC cards, otherwise it just gets stuck saying "card isn't formatted, do you want to format it? (yes) Oh, formatting failed" etc.
In case anyone else has problems like this the update is KB955704, available from link below.
http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=19364
This means I can now just pull the card from my Z2 and stick my music etc. on from there, and pull the photos etc off from there.
It seems even when connecting to PC via the phone's USB lead there are problems until this update is in - I could see the files but not edit them, move, copy, etc etc which is what was REALLY confusing me.
Sorry if I seemed a bit noobie about that. I've actually been flashing my phones, tinkering etc for years and years but I guess I've not had an SDXC card before so didn't realise it wouldn't play ball.
MUCH better now - I don't really care what the KitKat limitations are now I can just transfer files "properly".
Cheers for the explanation about KitKat though, that is very useful.
So I wasted a day transferring files via Dropbox when a poxy Windows update would have solved it. You live and learn. I hope I can save someone else the hassle!
The pre-installed File Commander can write to the internal storage. So getting files onto the external add card is two stages. I copy over WiFi from my NAS to internal storage using ES file explorer, then copy from internal to external using file commander.

Thanks for that, I found that File Commander trick earlier. Problem I had to get around was I went nuts and installed every single app I ever bought but couldn't use properly on my old phones - namely the GTA games which were broken for my Xperia S. I ran out of internal storage within hours of getting my Z2... I got over-excited. I've calmed down now and deleted a load so there's more space and my SD card works fine now when in a card reader.
I've never been able to manage files directly from Explorer on my PC though when the phone is directly connected, either on the S and now the Z2. I think it worked to a point on my Xperia X10 but I mostly used Wifi File Explorer... which isn't working on my Z2 unfortunately, probably due to the Kit Kat restrictions mentioned.
I can kind of see why they did that - my phones used to get full of mystery folders full of crap over time - but it's a shame it breaks a lot of the old ways I used to get things done.
Anyway I apologise if we've gone off topic but thanks everyone for your very helpful hints and advice. I'm actually looking forward to getting my O2 Xperia Z tablet with the bundled offer (£99 for an Xperia Z tablet, yes please O2!) because it will most likely be permanently stuck on good, old-fashioned Jelly Bean. I've not seen much in Kit Kat that has thrilled me. I don't think I'd update to Kit Kat if I had a choice given how firmly a grip of your nuts they have now.
Cheers!
Hey guys with the 128gb card. How does 4K video go when writing to the card? Is it fast enough?

Hi I don't have a 128gb in mines but rather a Sandisk ULTRA 64Gb class 10 SDXC card.
I shot a 2 minute 4k video this afternoon which was saved directly onto the SDcard and on playback there seemed to be no problems whatsoever playing it back.
I hope that helps.
I have a 128gb card. Just recorded 1 minute of 4k to sd card and played back without problems. File size 391mb.

What sort of write speeds do you get?
I'm thinking of buying this to replace my 64gb card.
I don't why I missed this but since rooting my phone I've played around with other android and Linux devices. It occurred to me that my fire tv and my linkage router with usb storage capabilities both have external drives that I wound up formatting to ext 4. For me it's been just the one that works best and is essential for using the swap data option fire tv.
One thing I hate about ext 4 is how a good amount of disk space gets wasted. Not a big deal on my other devices are 1tb or more but I might miss that space on the much smaller sd card.
I'm just looking for advice/tips. Also I need to know if formatting will screw things up since I'm using apps to move things to the external.
This is a new idea for me. I don't even know the format of my ext sd. I'd bet anything it's fat32 since it was used in my dumb phone years ago and I probably used Windows to format.
