“We wanted to know if two striped drives in the LaCie Little Big Disk (LBD) Thunderbolt would transfer data as fast as the same two drives in the Promise Pegasus X4,” rob-ART Morgan reports for Bare Feats.
“To stress both enclosures to the limit, we used dual 6Gb/s solid state drives (SSDs),” Morgan reports. “Then for perspective, we included two models of notebook hard disk drives (HDDs).”
Morgan reports, “The Promise Pegasus R4 writes large sequential data files (captures video) significantly faster than the LaCie Little Big Disk when both are using SSDs. This is significant in that, according to the data rate calculators, 2048×1556 10-bit RGB 29.97 fps video requires 382MB/s to avoid dropped frames. The LBD falls short of this target. The Pegasus exceeds that target with either dual 6G SSDs or quad HDDs.”
