Hardware RAID5
Is in terms of functionality this one behaves just like the 'Software RAID5', but a dedicated RAID
interface controller card manages the virtual drive. RAID5 is depreciated for use with Apresa
because the chance to rebuild a RAID5 volume build with the modern high capacity hard drives is
not at an acceptable level. The use of a high quality RAID controller with write cache & battery
backup, will provide enough write performance for an Apresa with a high number of channels, but
when considering the chance of rebuild success RAID5 is not an option to consider.
Hardware RAID10
This combo of RAID0 and RAID1 is an excellent choice for Apresa with a high number of channels.
Use the advised controller with cache/BBU for best write speed and reliable rebuild.
