Which SanDisk cards support wear-leveling ?

Hi,
I'm looking to use SHDC cards as filesyastem and storage in Raspberry Pi and other mbedded linux devices. I had few SanDisk and other manufacturers cards fail quite fast, after only few days of usaga so my main concern is to get SDHC cards that have absolute best wear-leveling for maximum life time.

 

Speed and capacity of card is much less important to me.

 

Is there any list that shows which SanDisk cards have controller that supports wear-leveling? Also knowing which SDHC has just basic wear-leveling and which one has premium wear-leveling controller would also help a lot.

 

Cheers,

Valent.

I would be very much interested too!

 

I could only find this page mentioning Wear Leveling: "SanDisk Extreme Pro® SDXC™ UHS-I Memory Card"

I'm with the OP too. Using a Sandisk Extreme SDHC on our laptop and planning to use another on our next NAS.

Also my father has got one for his chromebook (in absence of information on wear-levelling bought a Verbatim). And I'm looking for a coiple of usb sticks for live OS and my coming Cb too. Not talking of Android devices.

 

Please include the type of wear-leveling implemented: dynamic or static.

 

Seems flash memories aren't looked for cameras only these days.

 all sandisk products and all modern flash memory from any reputable manufacturer use wear leveling. sandisk products use dynamic wear leveling.

There are different WL algorythms, with variing cost and efficiency. SDcards have a poor algorythm; eMMC chips are much better (I have bought true eMMC cards with MMC-SD adater); I am also giving a try to Sandisk cards certified for video recording (said to be 2y waranty, but with a much greater write cycles).

 

I had bought a Transcend Premium 3y ago; used it less than 10y; it died yesterday while I was trying to wirte 1G on it; it was a rescue storage (backup) for critical file (there is no data loss for me because those data are store on 5 disks); so in short, I wrote 2G 3y ago, left the card in a safe for 3y, and tried to update the content. The card burnt after 5mn. The presence of card is detected by adapter at electrical level, but the volume has 0B (zero byte). After checking, Transcend have only 1y waranty; that's why I prefer Sandisk: Ultra cards are given for 5y, Extreme for 10y. And even if high endurance are only 2y, they have 10x bigger write cycle.
