I read an article about that, and if I recall correctly the assumption |
5 |
was that the likelihood of data loss occurring due to the barriers |
6 |
issue was negligible. I have no expertise to decide on that matter, |
7 |
but the fact that pretty much every linux distribution chooses ext3 by |
8 |
default suggests it is the safest (at least for simple desktop/laptop |
9 |
usage), no? |

Somewhat offtopic: |

What do you suggest for me? I care about data safety, but am too lazy |
13 |
to make frequent backups, so filesystem robustness and availability of |
14 |
data recovery tools is pretty important; and as I said before, the |
15 |
only performance problem with my computer that I think may be related |
16 |
to filesystem is boot time and launching heavy programs not in cache; |
17 |
keep in mind my root partition is only 3,8 GB used and 93% free - |
18 |
maybe in this condition the filesystem is not stressed and only the |
19 |
actual HD speed matters? Valerie Henson from VAH Consulting says that |
20 |
every file system goes fast with: |
21 |
|
22 |
* O(1000) files per directory |
23 |
* File size a few KB to a few GB |
24 |
* Read-mostly access |
25 |
* Infrequent file creation/deletion |
26 |
* Sequential file read/write patterns |
27 |
* Shallow directory depth (< 10 levels) |
28 |
* Total file system size O(100 GB) |
