I'll simply call a couple of benefits and drawback factors for each and every. This is by no suggests a laborious checklist, simply a sign. If there are some large noninclusions that require to be in this checklist, leave a comment and also I'll add them, so we get a wonderful, large checklist in one area.

ext4

Pro:

  • sustained by all distro's, business and also not, and also based upon ext3, so it's extensively examined, secure and also tried and tested
  • all kinds for wonderful attributes (like levels, subsecond timestamps) which ext3 does not have.

Disadvantage:

XFS

Pro:

  • assistance for substantial filesystems (approximately 8 exabytes (yes, 'exa') on 64 - little bit systems)
  • on-line defrag
  • sustained on upcoming RHEL6 as the 'huge filesystem' alternative
  • tried and tested record : xfs has actually been around for ages

Con:

  • wikipedia mentions slow-moving metadata procedures, yet I would not find out about that
  • possible dataloss on power cut, UPS is advised, not actually ideal for residence systems

JFS

Pro:

  • claimed to be rapid (I have little experience with JFS)
  • came from AIX : tried and tested modern technology

Con:

  • made use of and also sustained by basically no - one, other than IBM (remedy me if I'm incorrect ; I have actually never ever seen or read about JFS made use of in manufacturing, though it clearly has to be, someplace)

ReiserFS

Pro:

  • quickly with tiny documents
  • really room reliable
  • secure and also fully grown

Con:

  • not really energetic task any longer, future generation reiser 4 has actually prospered it
  • no online defragmenter

Reiser 4

Pro:

  • really quickly with tiny documents
  • atomic purchases
  • really room reliable
  • metadata namespaces
  • plugin style, (crypto, compression, dedup and also meta information plugins feasible)

Con:

  • Reiser4 has a really unclear future and also has actually not been combined yet
  • major sustaining distro (SuSE) dropped it years ago
  • Hans Reiser's 'lawful concerns' are not actually aiding

I advise this page for more analysis.
