Does Ext4 filesystem diminishes life of SSD?
I am planning to install Ubuntu/Debian on a new SSD and was searching for info when stumbled upon this link:

If you have an SSD you should use JFS.

Does JFS have journelling in case of crashes to backup data? |
JFS : Journaled File System for Linux ...
http://jfs.sourceforge.net/ "IBM's journaled file system technology, currently used in IBM enterprise servers" http://en.wikipedia.org/wiki/JFS_%28file_system%29 - |
Should ?. What about f2fs - at east it was designed specifically for FTL devices.
As for me, I happily use ext4. |
The old problem of too many writes to disk doesn't exist with modern SSD, however it is advisable to use 'noatime' in your /etc/fstab entry, and not put 'swap' onto an SSD, other than that, it doesn't matter which filesystem you choose to use.
|
Really it doesn't matter I've got ext 4 running on an OCZ Vertex+, it's been on ext4 for two years. Before that it was HFS+ swap has been on the dive in both instances ext4 is not killing drives
|
Does not look like it so far. YMMV from mine.
Code:
# parted -l I never liked Apple anyways. But this one fell off a truck. (just the drive, not the laptop). Code:
~$ inxi -M |

JFS is still the most recommended file system for GNU/Linux. |
Whatever filesystem you decide to use, make sure TRIM is enabled and I would also use noatime in fstab.
JFS has TRIM support in newer kernels, it is journaled, and it is faster than other filesystems on a SSD: http://www.phoronix.com/scan.php?pag...38_large&num=1 I've been using it for a long time and never had any problems. |

Many SSD's have basically all that you need to secure data without a journal. All SSD's will slow down way too soon. It's their dirty little secret that they don't tell us.
Disable journal would be my suggestion. Move swap off to mechanical or don't use swap. |

I am planning to install Debian Linux into a new SSD. formatting with GPT partition table. with JFS, for any unforeseen reason, power failure occurs, can it be recovered as easily as ext4? with ext4, running a fsck.ext4 -fvy /dev/sdX solves the problem most of the time. So, Although not enough reasons cited, JFS is unofficially preferred for SSDs in Gnu/Linux? |
JFS supports TRIM very well and is a Copy-On-Write file system.
JFS has great data recovery support compared to other file systems. As long as the file system journal writes are kept current regularly, you'll rarely experience data loss. It's no ZFS, but it's better than BtrFS is currently. |
