A particularly interesting news came a few days ago in HWBOX.gr , but unfortunately we can not confirm yet if it is true or not. The famous maker of hard drives Seagate , will release the Momentus hybrid drives XT . What exactly represents the word hybrid; Imagine a hard disk drive (HDD) and a 4GB Solid-State Drive (SSD) memory to SLC on a drive! Coming in capacities of 250GB, 320GB and 500GB drives the new hybrid has speed 7200 rpm minutes, 32MB cache , 4GB Solid State Memory and SATA 3.0 Gbps interface. Additionally use technology NCQ (Native Command queing), which dramatically increases performance by allowing the housekeeping commands read and write.
Enjoy the unlimited capacity of HDDs and the speed of SSDs in a single disk! The initial results are 80% faster than traditional 7200RPM HDDs in PCMark Vantage, quiet and very cold. Expected to be used in high-end laptops, workstations and small form factor PCs, while supporting standards and USB 3.0 and eSATA.
