Seagate ships mobile hybrid hard drives

Over a year after first announcing its first hybrid hard drive for notebooks, Seagate has at last begun shipping the product, according to a report by ExtremeTech. Known as the Momentus 5400 PSD, the drive is a 2.5" model with a 5400 RPM spindle speed, capacities up to 160GB, and 256MB of non-volatile flash cache memory. That cache works together with Windows Vista’s ReadyDrive technology to reduce boot times and lower power consumption, thereby improving battery life.

The drive has now shipped to five PC vendors, "four of which are qualifying the drive for inclusion in a notebook PC," ExtremeTech says. According to Seagate Product Manager Melissa Johnson, consumers can expect to pay a 25-30% price premium for the drive compared to a regular, non-hybrid model. However, the investment may not yield major performance gains yet: Johnson tells ExtremeTech, "It’s just not getting the orders of magnitude experiences that Microsoft originally touted… there are issues both with the BIOS and devices drivers; they don’t know how to utilize the flash."

    I don’t get it. Flash prices are freakin low these days, and they only include 256MB on each drive ? What gives ? Increase that to a nice 2 – 4GB and then you should start seeing a difference. Oh, and a working BIOS + drivers would help too..

    Heh, i bet Apple will implement this right on their next version of MacBook Pros 🙂

    I think Vista’s lauded boot times have been negated by the fact thatg{<:<}g * We still need to reboot for [monthly] patches. * We still have hotfixes, rollups, because it's not a solid product. * Because it's not solid we're rebooting more than we would normally

    HP said several months back that they had no plans to offer hybrid drives, though they continue to evaluate them, because they weren’t seeing enough benefit to justify the higher cost.

      They did the right thing. I played around 2 hybrid drives for a week or so a while back (I believe they were Toshiba) and I couldn’t see any sort of significant gain in performance or battery life. Unless the cache on the drives is big enough (my guess is ~1-2GB) to allow the drive to spin down for long intervals its pretty much pointless.
