Two drives in RAID 0 give the Seagate Backup Plus Fast drive a significant performance advantage.Īnd being hard-drive based, the Backup Plus Fast can’t touch the sustained throughput (large file performance) of solid-state drives such as Apricorn’s Aegis 3.0, though it matches up well with those products with small files. The Little Big Disk, however, blew the Backup Plus Fast away in Crystal Disk Mark’s random write tests-Thunderbolt has some technical advantages. It even bested LaCie’s Thunderbolt-based, RAID 0 dual-drive Little Big Disk by a small margin in sustained throughput. That’s enough to take care of just about any backup job. This approach also has the happy effect of providing twice the capacity-4 terabytes-of any single 2.5-inch drive solution. Since it writes half the data to one drive and half to a second drive at the same time, you should theoretically get nearly twice the performance. Seagate has upped the performance ante for portable backup hard drives by stacking two 2TB drives, striped in RAID 0, inside its Backup Plus Fast USB 3.0.
