For using SSDs: Are there any format/mount parameters that should be set for using btrfs on SSDs (other than the "ssd" mount option)?
General questions: How long is the 'delay' for the delayed alloc? Are file allocations aligned to 4kiB boundaries, or larger? What byte value is used to pad unused space? (Aside: For some, the erased state reads all 0x00, and for others the erased state reads all 0xff.) Background: I've got a mix of various 120/128GB SSDs to newly set up. I will be using ext4 on the critical ones, but also wish to compare with btrfs... The mix includes some SSDs with the Sandforce controller that implements its own data compression and data deduplication. How well does btrfs fit with those compared to other non-data-compression controllers?
