I am going to be installing linux to a USB flash drive (an actual install, not a "live usb"). I need it to be completely portable, so I can't realistically have the high-access partitions (swap, var, etc.) located on a HDD instead. I've read a lot about the limited life of flash memory, as well as the advantages + disadvantages of LVM, but have not found any information that addresses my question. Assuming a reasonable amount of RAM (to minimize swappiness), can using or not using an LVM affect the number of reads/writes done and therefore prolong or shorten the drive's lifespan?
