Tokyo Japan, 9th July 2014 – Buffalo Inc., a global leader in the design, development and manufacturing of storage and wireless networking solutions, today announced the launch of the HD-PGDU3 series. BUFFALO’s new HD-PGDU3 portable hard drive features a whopping 1 GB DRAM cache. The HD-PGDU3 boasts the world’s fastest write speed*1, an incredible 400.7 MB/s.*2 The increased speed is achieved with the drive—the hardware—itself, enabling high-speed data transfers not only with Windows PC running speed-boosting software, but also on conventional Macs with no such utilities to enhance speed.*3 Combining a hard disk drive with a high-capacity DRAM cache achieves transfer speeds of a solid-state drive while providing tremendous storage space at a cost lower than that of an equivalent SSD. This is the perfect unit for those who are unsatisfied with the transfer speeds of previous portable HDD models. *1Refers to single 2.5″ hard disk-equipped portable HDDs (as tested by BUFFALO, May 2014) *2 (Measurement Environment) [PC] SONY SVJ202AJ/CPU: Intel Core i3 3217U 1.8 GHz/Memory: DDR3 8GB/OS: Windows 8.1/Internal HDD: HTS545050A7E380; [HDD] HD-PGD1.0U3B USB 3.0 portable hard drive with DRAM cache, conventional HD-PA256TU3S USB3.0 SSD, and conventional HD-PNF1.0U3-BB USB3.0 hard disk drive.
