[...] Some people think that using a journaling filesystem will prematurely wear a USB stick, but this guy doesn’t think so. [...]

I ordered Patriot SSD (http://www.patriotmemory.com/products/detailp.jsp?prodline=8&catid=21&prodgroupid=141&id=911&type=17) – manufacturer gives 10 years warranty for this disk. Do we really need to worry about data stored on such SSD more than on ordinary HD? I don’t think so…

Some anecdotic data: the 16 GB SSD in my Asus EeePC 900 died in under a year, with read errors in the spot that used to contain the ext3 journal.

I suspect poor write leveling and decided to go with ext2 in the replacement drive.

[...] Re: Partitioning 2 HD Are these remarks still relevant for ssd's? I don't know what kind of ssd the author has, but I've seen calculations that ssd's can last 27 years under normal usage. Let's say that you put a swap partition on it and it might be reduced to 7 years. This is still more than long enough for any home user. If you add trim support and reduce kernel swappiness, these number should even increase. Here is one article that I read about the subject: No SWAP Partition, Journaling Filesystems, … on a SSD? | Robert Penz Blog [...]

Please note that this is only if you use “real” SSDs. Many cheap “SSDs” are technically just SD-Cards with an IDE/SATA-Interface – i broke 3 Cards of different brands (8GB/16GB) in a Year…

I think he means writing the same 4k block 100,000 times with a speed of 50MB/s takes 7.8 seconds.

You assume that each write of a block takes one life cycle of all cells -> after writing ~400MB the SSD fails ?
This calculation can be silently ignored…
