bbu

My datacenter says that each rack has primary and backup power on each rack. I assume this means there is a UPS for each server. Therefore, do I have any need of getting a BBU for the following setup?

Intel Cherry 520 SSD x 4 RAID 10 LSI-9260 with WRITEBACK CACHE ENABLED

I have heard that without a BBU the data in the cache could be lost. Since my needs aren't mission-critical, I can afford to lose some data. But would the rest of the data on the HD be corrupted?
