Hi all,
Our application is heavy write and IO utilisation has been the problem for us for a while. We've decided to use RAID 10 of 4x500GB Samsung 840 Pro for the master server. I'm aware of write cache issue on SSDs in case of power loss. However, our hosting provider doesn't offer any other choices of SSD drives with supercapacitor. To minimise risk, we will also set up another RAID 10 SAS in streaming replication mode. For our application, a few seconds of data loss is acceptable.
My question is, would corrupted data files on the primary server affect the streaming standby? In other word, is this setup acceptable in terms of minimising deficiency of SSDs?
Cheers,
Cuong
