Speed up your RAID: moving journal to SSD
- bifrost 14y agoSo, I've done this, but its got one pretty important caveat. If you're using a consumer level SSD, and doing a lot of writes, be prepared for your SSD to die quickly, like possibly within 6 months. Also, when that SSD dies, it may take your ext2/3fs with it (been there, glad I had backups). If you're thinking about RAID1-ing the SSD, also remember that since this is solid state media, they're likely to die at the same time.
