Write Cache

Hi,

We are installing Dell MD3820i storage and we are trying to benchmark the disks performance, we are facing write performance issue, after check we found that the write cache is increasing the performance by 50%, we are using MySQL with Innodb and we are afraid of data corruption if the write cache is enabled,

please advise if we enable write cache with mirroring, can we face data corruption if the storage suddenly turned off

Thanks.
