Vista Supports Hybrid Storage Drives, Microsoft Says

Microsoft rebuts talk at DiskCon that current Vista drivers must be improved for hybrid drives to work better.

Microsoft on Sept. 21 denied claims by hard drive industry executives and analysts that the worlds largest software company isnt providing optimized drivers for the new hybrid drives about to come into the market.

"Microsoft certainly does provide drivers for hybrid hard drives in Vista," Matt Ayers, program manager in the Windows Client Performance group for Microsoft, based in Redmond, Wash., told eWEEK.

"Theyve been in there all along, and they work with any hard drive. I dont quite understand the issue here. And about optimized drivers—we never send out any drivers that arent optimized," Ayers said.

Hybrid hard drives combine nonvolatile, solid state flash memory and traditional disk drives. The benefits of using hybrid drives include improved power efficiency, extended notebook battery life gained by powering off the spin motor and operating out of nonvolatile memory, faster system response time, and increased durability, since spinning the drive down creates less mechanical movement and increases reliability.

Ayers is in charge of Microsofts ReadyBoost and ReadyDrive drivers, which are designed to work in hybrid drives and are included in Vista. "They leverage flash memory to improve a PCs responsiveness," Ayers told eWEEK.

ReadyDrive uses either native hard drive RAM or the nonvolatile flash cache Turbo Memory (formerly called "Robson"), but not both, Ayers said. Turbo Memory hardware, due to architectural requirements, requires special drivers supplied by Intel, he said.

Hard drive industry executives and analysts complained about a lack of Microsoft Driver support during the DiskCon conference Sept. 19-20 in Santa Clara, Calif. These critics claimed that to work optimally in a Vista system, the hybrid drives must be supported by better drivers that are not now available.

"If you talk to the hard drive manufacturers…" David Reinsel, director of storage research for IDC, told eWEEK, "I think the fact of the matter is that there are tweaks that need to be done, and each of the drive vendors is looking at how they can optimize the drivers to make it work even better.

"Will a hybrid drive work? Yeah. ... If we start going to head-to-head comparisons where you pit a hybrid hard drive against a regular 2.5-inch, 5400 or 7200 [rpm] drive or against an SSD [solid state drive], is the hybrid going to shine as good as it can? The word were getting is no—that the drivers arent completely baked in, that they still need work.

"And again, the rumors still hold pretty hard that it looks like Microsoft is going to back off on its June 2008 requirement of applications to support hybrid hard drives in order to get the Premium Vista logo compatibility thing," Reinsel said.

"Microsoft is sitting there saying thats not true; well, youve got to take them at their word that its not true, but thats certainly what we were hearing," he said.
