I have had an SSD for about two years now and have never bothered enabling the discard mount option. I left some of the drive unpartitioned so that some blocks would never be written to and thus, the drive should never run out of erase blocks. About 6 months ago I did a benchmark and noticed that it wasn't quite as fast as it was when it was new ( though still plenty fast ), so I migrated my data off and reset the drive with an hdparm security erase, then moved my data back. This restored performance to tip top. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJPhgikAAoJEJrBOlT6nu75ue4IAJLdQ/ClkhMnkQ4vIgvQxGYX 3GTJcirOBowmw6Xhot7oTkttirkqPcdUHEmnNdfSrDWvwGtG045zkKDtswBr+cuG 4RXNfoUBSxressswEKmLTROq/GysG/i1Jn92RHELWxq7p9SKac0Q+Iv98yZ+28Rp P3Ql5muBYWMB4OK4K1bvzwg8QMuggkl46uh+hXxA1GwvoYF6AVkx1L0olDzii1qc obv4+fs8D7pnBlR+mZLBrssFP7ZswyMcNeJzMGRrKBhB1xfO6GMuhUiY5XJ5qpYv UgEY2vBw5gAe041rIOJcsfjEtbsyqzif38xxhoHXHmS56y+0yxwQs34BtaYj5cc= =vcuD -----END PGP SIGNATURE----- -- Ubuntu-devel-discuss mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
