Micro Drive & SDHC, which one is faster?

[wu5262]

Hi guys, since i am getting my DOPOD U1000 this week, i want to know where is the best place to install my program and store my music and photo.

I have purchase a 4GB mini SDHC. Compare to the micro drive, which one should i use to install my program. (which one is faster?)

For music & movie, i think i will store it in Micro Drive. How about photos? Will there be delays if i store the photo taken by camera in Micro drive? or is it better to store in SDHC?

Thank

I had the Samsung SGH-i300. Nice WM Smartphone with 4 GB micro drive....it drains the battery like a starving beast. With improvements in technology, things should be a little better now, but don't expect too much, hence 128 ROM & 256 RAM (for regularly used apps and accessed files).

Micro drive will drain your battery severely. Best way to look at it is this way; put the files that you will most frequently access on your SDHC card and larger files like movies on your micro drive.

Photos? Difficult one really. Personally, I have two categories of photos; Newly taken ones which I want to see regularly for a while + Wallpapers etc [store these on SD card]

Older collection of Photos/Albums- occasional use but important to me personally th have always available [Store these on Micro Drive]

Movies and Music and PC data for various reasons [Micro Drive]

Regularly used apps not installed to default device location [SD Card]

Don't forget the micro drive is mechanical and therefore drains battery power more that's why it's good to use SD card for heavy use.

Thanks mackaby007, that answer every single of my question. Will indeed follow the above setup when my device is here :)

Micro Drive or Memory or ram or all:( ?

only the ram in device is clear, micro drive and mini sd will stay un-touch. Of course , there is a function that you can format the micro alone as well

tanX a lot:D:D:D
with this thing we must install programs on which? beacuse if a program have problem we must reset and formatting and other information(music,videoand..) willl be deleted!!!!

see above post:

Program you use a lot, everyday! (on device memory)
Program you use sometimes, (on sd card)
Music and Video (on micro drive)
Flash photo (sd card)
Old photo (move to micro drive)

Hope that help :)

Also Arya, don't forget that we're talking about WM5 here. There will likely not be many problems if you were using the same apps on a previous WM5 PPC.

Personally I will set up as follows:

1) Only install apps which have proved to be no probs in over 3 months of use, prior to getting the X7500.

2) Test each app for only 10-15 minutes with a couple of soft resets and whilst other apps run in background.

3) No more than essential apps initially (don't even want a X7500 if it can't run this).

4) These apps for me are: Batti v2.0, WA2, Resco Photo Viewer, Total Commander, Coreplayer (or TCPMP) and PocketMusic. Providing these work without issue for 15 minutes - 60 minutes, I do a Full backup with Spb Backup. Then I do a contacts backup using Spb Backup. Then I have my primary set-up to revert to if things go wrong as I install other apps in the future.

5) This should really come before the backup. Ensure UMTS connects and disconnects as it should and that my primary Wi-fi is protected (secured) and my sim contacts have been saved to my outlook contacts.

6)That's the basics. Then transfer all 'storage data' like Movies, Music and occasionally accessed Photos to Micro-Drive. Also PC data to be used in other places other than home or work can also be stored here.

7) Personal Ring-tone folder - SD Card

8) Regularly accessed Photos and recently taken Photos - SD Card...Why?...because I often take my SD card to transfer photos to mine and other PC's. If the X7500 has mass storage capabilities due to USB host capabilities, then this may change to Micro-Drive only, but that means I always have to walk with a lead. (No thanks - the X75 is big enough)

9)Before -all games to SD card...Now - all games to device unless they exceed 15mb.

10)Backup Device and have duplicate copy of personalized file structure and folders on Micro Drive, just in case.

I should now have 3 Backups:

1) Primary backup - Essential apps with everything working beautifully.

2) Contacts backup - make a scheduled backup of this once a week to include new additions and replace last Contacts backup.

3)Big Backup - Final and fully loaded Device backup including SD card and micr drive Backup.


Lastly should have been first. Play with original ROM without 3rd party apps for at least 48 hours (however many days it takes to achieve the hours). Why?..to ensure you are happy with the ROM before you go through all this work.

Remember the device backup is not transferable to other ROMs, nor will applications that were installed to SD card or Micro drive. Hence the reason why I put 'storage data' on the micro drive and SD card, because it can be used again.

Then I just install whatever whenever, without fear of a total rebuild.


Not least of all, be prepared to do it all over again when WM6 becomes available for the X7500. :)

And yes I'll be doing it - can live without Video calling. :)


Sorry for the long post people, but I hope someone finds it useful as it has taken me years to get a system that gives me no problems at all.....but that's exactly what I always end up with after all the problems have been resolved and tweaks applied...a device to die for. Not literally.:)

your informations are very good and i hope every one use it
tanX a lot too

I have a 2GB Trancend 80x MiniSD and ran the speed benchmark test using SK Tools. Here's the result :

Storage Card (write); 535.28;KB/sec
Storage Card (read); 875.84;KB/sec
MicroDrive (write);14733.81;KB/sec
MicroDrive (read);11792.71;KB/sec

Storage card wins hands down as expected.

sorry i am a bit confuse here, i though the bigger value is better, so storage card can write 535.28 Kb per second where micro drive can write 14733.81 Kb per second. Or am i wrong here?

[Moskus]

Yeah, that's how I'm reading those values.

[k_kirk]

Guys, you're absolutely right ofcourse. Its 12:38AM here and I think I should go to sleep. Playing with the new U1000 for 8 hours flat I think I am starting to loose it. Thanks for setting the record straight...

Hi k_Kik,

Could I seek the following clarification?

How was your card formatted?
- Do you back up the FAT table?
- Is it with FAT32 ?
- What was your cluster size?

Also, SK tools seems to always give a very good reading for the first test, then have a drastically lowered reading from second test onward (That has been my observation). Is your reading the first one or the second one onward? Also, the reading differs drastically depending on the above settings used to format the card. My own test shows the following: (All FAT 32 formatting and without FAT table backup)

Cluster size----1st write--1st read----subsequent write/read
0.5K---------- 13.26KB/s--798KB/s---not tested
1K------------15.76-------931------not tested
2K------------238---------930------not tested
4K------------264---------931 -----not tested
8K------------518---------931-------270/922-- 266/922
16K---------- 490---------911------235/748----232/688
32K----------518---------950------241/701------240/708----243/720


I also tested with FAT table backup as a formatting setting, and got the following result
32k---------144---------821-------91/750

My card is a class 4 4GB miniSDHC card made by Toshiba, manufactured in Japan.

It appears that in my case the best performance that SKtools would report comes from FAT32 with no FAT table backup, and cluster size of 32KB. Is your card formatted with the same setting?
