[arm-allstar] RPi2 image file shasums-- Was: Arch vulnerabilities

[Doug Bade]

I can add:

I was able to get nice clean installs and fast boots from PNY 16gb class 10+
( rated up to 40Mb??)   MicroSD cards I bought from Micro Center for $10.00
ea a couple days ago.. I had to do a complete fat32 format on them, I use
the HP flash formatting tool to do that.

Specific Product information:

Microcenter SKU:

477141 

Mfr Part #:

P-SDU16G10-EFS2 

UPC:

751492498096 

 

Mine came up fine.. before the complete format I had file system errors out
the wazoo.

Class 4 does seem to be less than optimal for a 4gb file system.. at least
it will be slower to load and image..

 

Microcenter has Element 14 PI2's for $29.99 again ( really only $5.00 off)
.. and cases for $7.99

 

I just recently joined the PI Allstar  users group although I have been an
Allstar user for quite a while on PC platform.

You mentioned a 16G class 4 card. We recommend nothing less than a class 10
and in most cases we are using class 10 plus cards at this time. Also
Sandisk brand is recommended.  Using cheap unbranded cards and cards of less
than class 10  can lead to the problems that people often complain about in
other distributions. 

So far we have had very little SD card problems. I have programmed and run
dozens of systems and never had a problem with Sandisk class 10 8G or 16G
cards. I never expand the file system nor do I recommend doing it unless you
have a specific application. 

Write times vary mostly depending on the writer and USB speeds when you are
using a class 10 but are usually in the 10 minute range.

It is always a good idea to have a backup card but as long as you don't
change anything much from the setup in many cases it would be just as easy
to setup a new card if you lost the old one for some reason.
