Seagate is focusing on hybrid drives that combine a standard 5400rpm magnetic hard disk with a solid-state drive cache.
Laptop hard drive speeds aren’t tied strictly to revolutions per minute anymore, according to Seagate.
Seagate is abandoning 2.5-inch 7200rpm magnetic mobile hard drives for hybrids that have slower-rated RPMs but integrate large solid-state drive (SSD) caches, the company said today in a statement provided to CNET.
“Seagate’s innovation in the area of Solid State Hybrid Drives (SSHD) technology provides a much faster overall performance platform than 7200 RPM based hard drives,” the company said.
Bottom line: Seagate is saying a 5400rpm hard drive with a large SSD is faster than a pure 7200rpm magnetic drive.
Hard disk drive (HDD) and SSD hybrid configurations are showing up in lots of ultrabooks. PC makers like HP, Acer and Dell, typically integrate Intel mSATA SSD caches with standard spinning 5400rpm HDDs.
With this strategy, the company hopes to better meet cost-performance goals. Seagate-authorized distributors have been notified of these changes, and the company expects the last 7200rpm products to ship midsummer.
