Query: Very poor option. zero stars if I could

I had this unit a year and have never been satisfied. My goal was to have a common backup location for everyone on my LAN to share The unit always was very slow when reading or writing. More importantly recently I had one of the two hard drives fail . Should have been no problem since I was using RAID to mirror drives. WD did send out a replacement within a few days however after a lot of go arounds with WD tech support it turns out the second drive was also corrupted . I lost a tremendous amount of information I thought was totally secure. Very unreliabile. I would give this unit a zero (0) if I could . Do not rely on for data protection. Also this unit does not stream media files
