Thanks, will look back in the list archive. On 04/12/14 15:47, Nick Fisk wrote: Hi Eneko, There has been various discussions on the list previously as to the best SSD for Journal use.

Re: [ceph-users] Suitable SSDs for journal
Hi Eneko, There has been various discussions on the list previously as to the best SSD for Journal use. All of them have pretty much come to the conclusion that the Intel S3700 models are the best suited and in fact work out the cheapest in terms of write durability.
