Feature changed by: Hans de Raad (hcderaad) Feature #311341, revision 3 Title: Yast Partitioning give SSD best practice option openSUSE Distribution: Unconfirmed Priority Requester: Desirable Info Provider: Hans de Raad (hcderaad) Requested by: Hans de Raad (hcderaad) Partner organization: openSUSE.org Description: More and more laptops, netbooks, pc's, servers, actually anything with some kind of storage need is equipped with Solid State Disks. Although at first glance they may seem quite similar to harddisks, they really are a completely different species with some very different characteristics. It might be convenient for having an "SSD Best practise enabler" switch when creating partitions on disks in Yast, which would then automatically setup the features (and possibly others) mentioned in the "Why do we want this" part of this feature. Use Case: During installation (or partition editing) when a user configures a partition, the option would be presented to enable SSD Best practises. Business case (Partner benefit): openSUSE.org: Especially in the partitioning stage of the installation process one can make or break the extra performance one might gain from using SSD's. Especially aligning a filesystem to SSD erase block size and enabling TRIM on partitions are really noticeable performance enhancers. Also, when the SSD option is activated, the Swap partition would be suggested to be removed from the partition setup (if one is set). Discussion: #1: Arvin Schnell (aschnell) (2011-02-23 03:36:05) Parted (used by the YaST partitioner) already respects the alignment information provided by disks. Not having a swap partition disallowes suspend to disk, an essential feature on mobile devices. What detailed actions should be taken concerning the TRIM command? + #2: Hans de Raad (hcderaad) (2011-02-23 13:07:59) (reply to #1) + Concerning TRIM there already is some detailed info on the wiki: + http://en.opensuse.org/SDB:SSD_discard_%28trim%29_support The swap + option might be a bit farfetched but netbooks like the Acer Aspire One + discouraged the use of swapping because of the lifetime of the ssd + (will look for citation). I didnt know about the alignment in Yast, but + the biggest benefit should be gained from automatically mount SSD + partitions with TRIM enabled.
