Collaborates with the list of SD cards' good 'and' bad '
As you know, because we speak on this topic in due course, the problem of SD memory cards that do not follow the standard SD Card Association is serious: apart from losing power contained data at any time, can occur even Should these cards damaged the SD slot of our device (either Palm, MP3 player, camera, etc.).
Some details unmask these cards problematic
Hark0, MonkeyDreams, has suggested in comments a great idea: collect, among all, a list of our experiences with these memory cards. The list is here to work and only have to mandar an email to mgtroyas@pdatungsteno.com, with the following information:
- Manufacturer's name (if known).
- Capacity (in megabytes).
- Time Use (months, years which has been using).
- Apparatus in which usáis normally.
- If you detected any anomaly which are listed in this post: lack of the notch side, the switch read-only, and so on.
- Result of Use: if it works perfectly, or has ever lost the entire contents, or an aircraft crashed and he no longer accepts any SD card, etc..
- Alternatively, your name or nickname you want to appear on the list.
It is interesting that participation if the card works perfectly, as if it failed. If you have detected some of the differences between the cards are still the standard and those that do not, it would be very helpful if the indicáseis too. Among all build together a list of very useful side to decide the next SD card to buy. I hope that I encourage you to work, and thanks in advance.

Use in my T5 as a month ago and during a period of two months of an SD card 512Mb mark MarkVision and running smoothly.
I am currently a month ago from an SD of 1Gb Sandisk brand and is also working very well
I would remind you that there is software VFSMark to check the speed and performance of the different characteristics of your SD card.
One could make the table along with the values of our performance cards.
Well said, Manuel. As in everything, to buy a card must be taken into account all factors. We add to the request
The SD MarkVision, sold almost 40% less than the Sandisk or Kingston. So I am overcome with doubt that as good will, I wonder if it will be fast.
Masilva should make a test transfer and publish it so we will have a better idea about these super economic cards.
When I was using the SD MarkVision I worked a thousand wonders.
We pass the VFSMark my current card sandisk and the results were as follows:
VFSMark Results
Create File: 1070%
Delete File: 772%
File Write: 408%
File Read: 559%
Seek File: 786%
DB Export: 275%
Import DB: 328%
Record Access: 1005%
Resource Access: 914%
VFSMark: 679
You experts will say if that result is good, regular or bad.
Thanks Masilva. But do not tell that size in MB of your card… What about your MarkVision?
And let me know, after changing card, can feel a difference when you save a file and open the SD?
And according to the results seem to have a fast card.
In the first comment I made specify that the card is Sandisk 1Gb and MarkVision of 512Mb. The MarkVision was replaced by sandisk therefore not as I do the test, though not perceived any difference between the cards
Thanks Masilva. I sacks of doubts, I decided to buy one of those MarkVision. The I-128 because it is more…
