Note that reasonable quality SSDs are rated for writing something like 1000x their capacity. If you assume that vendors are lying through their teeth, and you get only 10% of the advertised number of writes, that would let you write the full disk from to back 100 times before you got a disk failure. Since venti is append-only, the amount of data written is limited to the size of the disk; if venti writes 4 index blcoks for each data block, and you filled the entire disk, that would put your writes at 5x capacity, which is a long way away from the rated 1000x capacity, or even the 100x capacity we had assumed. I think venti is fine for write capacity. The bigger risk is that SSDs need to remain powered on so that they don't lose data; thankfully, the index can be rebuilt if needed, so if you want your data to be long lived, I'd put the index purely on fast SSD, and the data on spinnning rust. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T4d8ba4236feb5d92-Mbc1059bea540fefe4c8a8e89 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
