Given the guesstimates in this article you likely won't wear out your SSD: http://www.anandtech.com/show/7173/samsung-ssd-840-evo-review-120gb-250gb-500gb-750gb-1tb-models-tested/3 That is specific to the Samsung, but they are all using similar tech so the numbers are should be similar. TLDR: @100GB/day a 500 MB drive should last 15 years. >> under these circumstances, is there an optimal choice for filesystem >> type given what i'll be doing on that drive? i'm running fedora 23 so >> ext4 is the simple and obvious choice, but does anyone have experience >> with a different filesystem that would be preferable? The CentOS 7 default is xfs. The Ubuntu 14.04 default is ext4. The only difference I have found is that xfs can re-size a filesystem over 16TiB. (Ext4 on Ubuntu 14.04 can resize up to 16TiB, and create, but not resize beyond 16TiB.) Performance wise they are each faster then the other in different edge cases. As the Fedora default is ext4, use ext4. Also ext4 is possibly the best debugged FS in the world. As RGB pointed out btrfs is still in the not-quite-trusted stage. Although I know people who claim they use it in production (and they are crazy). IMHO the advantages to btrfs are better suited to large multi-user filesystems anyway. Stuff like full data checksums to detect silent bit rot, snapshots, efficient data replication and backup, deduplication, and fully integrated raid5/6 (pending). -- sg
