What do these two do ('noatime' and circular log files)?
described the differences between SLC and MLC well. Only a few manufactures provide information which type the use. Transcend usally prints it on their packaging, but not always in the datasheet.
Circular log files are a patch (http://software.wwwi.com/syslogd/
) for standard syslogd by which it supports log files which have a fixed size and 'turn over' (start from the beginning) if the end is reached. I find this very useful for use placing logfiles on small ram-disk. The drawback is that these files can only be viewed by a special program ('clog') which understands the file format.
