LaCie's 5big Thunderbolt RAID drive offers fast speeds and copious amounts of storage, but at a high price. LaCie offers the 5big in either a 10TB or 20TB configuration, and TechRadar says all five disks are "easily replaceable." As a Thunderbolt-capable array it really comes through on the performance front, with PC Mag declaring it "one of the fastest drives" they've ever tested. TechRadar found the 5big faster than average speed-wise, but felt the drive is more "consistent in difficult conditions" though "still acceptably fast." With a starting price of $1200, and no Ethernet capabilities the 5big Thunderbolt only serves a small subset of users -- but if you're one of those users and need a dedicated RAID array, this is one to consider.
