SD (Secure Digital) cards and their associated SC/HC/XC technologies are the primary storage medium for the Raspberry Pi. The Pi Models A and B use SD Cards, and new models use Micro SD. SD cards are non-volatile flash memory.

up to 80 MB speed? There is no possibility of this. The SD card reader on the pi has a theoretical maximum of 25 MB/s and I have never seen a report of anything much over 20.

The one you bought probably has two partitions. The first is a small (~50 MB) FAT32 partition. The second is a larger (2-4 GB) ext4 (linux native) partition. The FAT32 one is required by the Broadc …

Is there any recommended or unrecommended format to use for Raspberry or does the system accept any FS? Follow the instructions for the OS you want to install. If you want to use one of the raw …

I have not used XBMC, but this is not a good idea WRT to a normal operating system unless you go to some lengths to set it up for that purpose. By implication, if XBMC isn't explicitly set up so, th …

Yes, it will be leveled across the entire card. Wear leveling obviously depends upon virtual addressing, and this is done by a microcontroller in the card. The operating system sees these addresses …

You did not say much -- you did not say what the card was for, etc. etc. But let's presume you formatted the card to use a Raspberry Pi-centric distribution such as Raspbian. This creates two partiti …

"it never received any IP. I do not have any screen" In other words it actually might not be running properly at all. The green led should flash twice evenly on boot, then perhaps flicker a bit …

As someone said: "fsck definitely causes more harm than good if the underlying hardware is somehow damaged; bad CPU, bad RAM, a dying hard drive, disk controller gone bad... in those cases more cor …

I have to bought a SD card for my raspberry pi. It is better to have a huge writing speed (like 95 MB/s) or it is not so important and I can buy slower SD (30 MB/s or 45 MB/s) ? No matter what, y …

Is there a way to avoid this, and let Raspberry do that automatically on that case? There's an easy way to do it generally (i.e., every boot) on Raspbian. Add this to /etc/rc.local: echo "-fy" …
