Could we get a baseline of a dedicated box with RAID-0 SSDs?
- justincormack 15y agoRaid 0 is not a baseline, and raid 0 ssd is not a useful configuration, given their failure rates.
- ericd 15y agoThat's false, it's a fine configuration for a slave database server where you don't care if it goes down after a year or two. In production you could make it a RAID 10 if you cared, but if we're just trying to get a sense for the numbers, RAID 0 is cheaper/easier. Or you could just do a single SSD as a baseline, but I would think that those who care enough about performance to go SSD are probably going for a RAID.
- justincormack 15y agoYou havent seen some of the failure cases in ssd then, months not years. Do not use raid 0.
- ericd 15y agoI've been running some RAID 0 SSDs on slaves for years under moderately heavy write load. If you leave enough space free for them to do wear leveling, there's no reason they should fail within months.
