For some people, 8TB might sound like a lot of storage, but depending on your data usage (*cough* BitTorrent *cough*), it might be just the right amount. I know that I could use a RAID storage device like this one on my workstation desk.
The Western Digital My Book Live Duo is a dual-drive RAID tablet-top device, which allows RAID 0 or 1 settings, though the 8TB model is only available with the RAID 0 setting, sacrificing redundancy for speed. The Ethernet-connected drives can work as a media server, streaming content to DLNA/UPnP devices, and offer secure remote access.
The 8TB box will set you back $660(USD), which is a lot, but we’re talking about a massive amount of storage. The 6TB model sells for $440 and the 4TB unit sells for $375. They’re available for pre-order now over at B&H Photo.
In my experience, Western Digital makes awesome hard drives and they’ve got an excellent warranty as well as customer care, so I buy all of my hard drives from them these days.
