BUY A COMPATIBLE CARD READER WITH YOUR MEMORY CARD

webmaster — Wed, 27 Apr 2005 19:30:39 GMT

PUBLIC ANNOUNCEMENT:

Dear Customers,

Many of you out there will own a laptop, a desktop, or indeed a printer, or other device that may now come with a built-in card reader for SD , MMC, MS, or other memory card formats.

Well i am afraid to tell you that even though you may have popped down to Dixons, or Currys this afternoon to buy the machine, there is absolutely no guarantee that the card reader will be able to handle the most recent memory cards that we stock, at the larger capacities.

By larger capacity, i mean MMC, SD, mini-SD, RS-MMC, and MS PRO DUO memory in capacities above 256MB...

This is because many of these embedded devices use older (and often cheaper) chipsets in them (dating from 1yr or 2yrs ago), which have never been designed or tested with memory cards like 1GB MobyMemory mini-SD, or our 2GB MMC, which only got released in the last month. It is understandable when you think about it.

When people try the cards in older readers, they invariably come crying and complaining to us claiming to have been sold a duff memory card, often after corrupting the card themselves by trying to use and format in one of these non-compatible readers.

To save everyone a lot of hassle, in emails, secondary purchases of card readers (which is very common), and returns for us to re-format and re-send out...

PLEASE BUY A COMPATIBLE USB2 CARD READER FROM US WHEN YOU BUY OUR BIGGER MEMORY CARDS, OR MAKE SURE THAT YOU HAVE ACCESS TO A COMPATIBLE MEMORY CARD READER.

We do try and encourage people to buy a reader with their cards, especially as the price is discounted that way too. So please take this recommendation seriously. Modern card readers like ours offer many times faster transfers to your memory card than bluetooth, or the USB cable supplied with your mobile phone.

It will save a lot of questions and frustrations later for you, and for us too

Yours sincerely,

Moby Memory Team (and from Support Team especially )

Want to write a HOWTO Guide for our forum?

webmaster — Thu, 30 Sep 2004 12:45:24 GMT

Calling all would be authors out there.!

We are looking for smartphone enthusiasts to author HOWTO guides for our forums.

Your HOWTO guide should deal with an aspect of your mobile phone in use with music, video, games or another application which requires you to use, and get the most out of, your MobyMemory card. The areas that we think will be most useful are for music and video conversion for specific mobiles. If there are things that are complicated to install or setup with your mobile and your home computer, that will be a good topic. Also, MAC owners out there have no guides on HOWTO setup their software; that would be great for them.

We will reward well-produced and useful HOWTO guides with items from our product range. And of course, you will keep the credit on the guide. Fame at last

Please PM or email me to check with possible HOWTO topics before you start (to make sure we have no clashes, and are of most use to our forum users). HOWTO authors will be added to our Contributors group and will be able to post their articles to a private forum where they can be reviewed prior to publication.

Many thanks.

About Us : MobyMemory - Memory for Mobiles

"We test and certify our memory cards so you don't have to"

Not all memory cards work well with mobile phones, even if the memory type matches. Some will not work at all, and others will not offer a reliable performance.

This makes the decision of which memory card to go for very difficult for the consumer. Not only do you have to find the right memory type (MMC/SD/RS-MMC/DV-RS-MMC/MMCMobile/SD/mini-SD/microSD/Transflash/Memory Stick Duo/Memory Stick PRO DUO) and memory size, but also to know it works well with your mobile phone.

This is the reason we setup MobyMemory.com because compatibility between the new era of smart mobile phones and memory cards is not something that can be relied upon.

We don't bad-mouth or discuss other manufacturers' memory on this site, because different manufacturers are continually working to improve their product base and reliability.. so that wouldn't be a fair business practice. For this reason we will not post up a list of compatible memory cards for each of the mobile phones.

At MobyMemory, we focus on our own game, which is to take the hard work out of the buying process for our customers, and offer them all the knowledge they need to make an informed choice.

We work with different manufacturers to find the most compatible memory we can (for mobile phone use) at each of the available memory sizes. we do so by testing sample sets of each of the cards with our test lab of mobile phones, and if necessary, work with the manufacturer to improve the quality of product, and sometimes introducing new capacity cards early into the European market. Because we order in quantity, we can pass on these savings to our customers.

We follow this up through after-sales support and offering information and guides to help customers get the most out of the memory for their mobiles (within these forums).

Thankfully, this strategy is working well for us so we don't plan on changing it anytime soon !

Please feel free to use this forum and our HOWTO guides and reviews to help you learn more about your mobile and memory card usage. And if you choose to do business with us, all the better

Yours sincerely,

MobyMemory Connectivity - Transfer Test Results

webmaster — Mon, 28 Jun 2004 01:12:01 GMT

The Official MobyMemory MMC - Connection Test Results:

1. Via USB2 Card Reader: (Fastest Transfer Mechanism available)

	Performance Tests: MobyMemory MMC Card (using USB2 7-in-1 MobyMemory Card Reader, Dell 400SC / Win2003 Server)
	Test File Size (Bytes)	WRITE Speed		READ Speed
	Test File Size (Bytes)	Duration (Secs.)	Bytes Transferred (per second)	Duration (Secs.)	Bytes Transferred (per second)
1Gb MMC	1,026,980,369	501	2,049,861	464	2,213,320
512mb MMC	511,199,012	250	2,044,796	236	2,166,098
256mb MMC	255,675,273	128	1,997,463	119	2,148,532
128mb MMC	128,159,862	65	1,971,690	60	2,135,998

Note:

These tests were conducted at the command-line using the copy command to transfer a single test file (.zip) to and from one connected drive (C: drive) to another ([Removable Drive]).

Read/write results will vary according to differing environmental test conditions; including USB port implementations on the PC (and USB port number used), other running operations on the PC(incl services etc), the card reader used, the USB cable, and the PC itself . For best results, the [Card Reader]-[Cable]-[PC USB port] connection should be USB2 (or USB Hi-Speed) end-to-end.

Also, the number of files transferred can have a significant impact on peformance (Many smaller files, of the same total size, will be slower to transfer than 1 large file).

2. Via PCMCIA Card Reader:

	Performance Tests: MobyMemory MMC Card (using PCMCIA 5-in-1 MobyMemory Card Reader, Samsung Q20, WinXP)
	Test File Size (Bytes)	WRITE Speed		READ Speed
	Test File Size (Bytes)	Duration (Secs.)	Bytes Transferred (per second)	Duration (Secs.)	Bytes Transferred (per second)
1Gb MMC	-*	-	-	-	-
512mb MMC	511,199,012	331	1,544,408	-	-
256mb MMC	255,675,273	167	1,530,990	-	-
128mb MMC	128,159,862	84	1,525,713	-	-

*5-in-1 PCMCIA Reader does not handle 1Gb MMC reliably.

Typically found to be 3/4^th to 2/3^rd speed of a USB2 connection.

3. Via USB Mobile Cable:

Speed varies for each mobile. Invariably slower than the first 2 connection options.

4. Via Bluetooth / 5. Infra-red (IrDA):

Again, speeds varies for each mobile and each bluetooth dongle. Invariably slower than the first 2 connection options.

IrDA is usually quicker than bluetooth implementations, but less flexible (needs clear line-of-sight, and to be within few feet of connecting device for good connection).
