I have a four year old Digital Storm system with 2x 2TB Western Digital Black Edition (model WD2002FAEX) hard drives in a RAID 0 configuration as my data storage volume. One of the drives failed and I'm looking for a replacement.

I'm looking at 6TB Seagate models, but I want to know if I should go with a consumer or enterprise drive. From what I understand, enterprise drives should be more reliable and have better warranties, but are there other advantages? Are there any disadvantages? Speed or performance? The two exact ones I'm looking at are model STBD6000100 (consumer) and ST6000NM0024 (enterprise). The enterprise one is only $50 more, so it seems worth it to me. I'll be buying two to make a RAID 0 volume.

It was shown when Backblaze open-sourced their hard-drive reliability numbers that enterprise drives were not more reliable than consumer drives.  HGST had the most reliable drives, followed by Western Digital, and Seagate had the worst reliability.

I would personally stick to 4TB or less (no shingling) of HGST or WD.
