For more informations about this format see microSD on Wikipedia.
A list of supported cards can be found at Supported microSD cards.
Importent note: Wear-leveling and ECC error correction and detection is not part of the SD card specification (version 2.0 SDHC), so please check for yourself that the SD(HC)-card support and use:
- built-in ECC error correction and detection
- Wear Leveling technology
If the manufacturer advertises the card with e.g. 1.000.000 MTBF, it might be a strong indication that the above features is used.
Other importent specifications are:
- Low power consumption
- 2/17/2008, notebookreview.com: SDHC Cards vs Hard Drive vs SSD Quote: "...That sounds like an absolutely manditory thing to have in flash storage ... and luckily "high-performance" SDHC cards such as the 16GB A-DATA SDHC card and many other class 6 cards from other manufacturers incorportate wear-leveling [Please check before you buy!]..."
- MicroSD(HC) cards are a sort of a SSD: December 7, 2008, robert.penz.name: No SWAP Partition, Journaling Filesystems, … on a SSD? Quote: "...They assume perfect wear leveling...We stay also with the 2 million cycles and assume a 16GB SSD *With 50 MByte/sec we get 20 years! *With 2 MByte/sec we get 519 years! *And even if we reduce the write cycles to 100.000 and write with 2 MByte/sec all the time we’re at 26 years!!...1. Never choose to use a journaling file system on the SSD partitions: Bullshit, you’re just risking data security. Stay with ext3...7. One more thing to consider is that flash-devices handle their space in blocks. The blocksize typically varies between 16KB and 512 KB. Therefore writing one byte may cause erase and rewrite of up to 512KB..."
