BenchmarkReviews.com: Mechanical hard disk technology has been the traditional standard for decades, refined to the point where it can deliver massive storage capacity beyond 3TB. Recently introduced solid-state drive storage solutions have begun pecking away at the market share thanks to their tremendous speeds and operational performance. Each offers an advantage over the other, leading manufacturers to seek out a hybrid solution that delivers quick access and large data capacity. The original 500GB Seagate's Momentus XT hybrid had the right ingredients, just not enough polish. More than a year later, the Seagate Momentus XT 750GB solid state hybrid drive (SSHD) returns with a double-size 8GB SLC NAND flash SSD buffer fused onto a larger 7200-RPM hard drive. Seagate FAST Factor firmware and Adaptive Memory Technology negate the need for third-party software, and makes this an all-in-one hybrid SSD solution. In this article Benchmark Reviews tests the Seagate Momentus XT (750GB model ST750LX003) in single and RAID-0 configurations against its predecessor, and several of the fastest notebook storage devices available.
