Infineon, Hitachi Prepare for Serial ATA Speed Boost

Advertisement (Why?)

Infineon Technologies AG, a leading semiconductor developer, and Hitachi Global Storage Technologies, a leading producer of hard disk drives (HDDs), on Friday unveiled their new read/write channel system-on-chip solutions for HDDs that can be combined with Infineon’s 6Gb/s Serdes Interface and achieve transfer rates that far exceed those of today’s Serial ATA-300 standard. “Infineon has demonstrated leadership in silicon development in its ability to deliver higher levels of performance. We are pleased with the results of the read-channel implementation,” said Steven Smith, senior director and general manager of Rochester, Minnesota, Hitachi Global Storage Technologies.

The new HDD read/write channel SOC provides speed and high-performance signal processing required for next-generation perpendicular recording for hard disk drives in enterprise applications. Complementary to the high-performance read channel, Infineon has also demonstrated silicon of its 6Gb/s multi-standard PHY (Physical Layer interface), capable to operate bit error free in “closed eye” environments required by the upcoming SAS 6G standard. The multi-standard PHY supports 6Gb/s SATA and SAS as well as Fibre-channel 4.25Gb/s standards and all their legacy modes. A 3Gb/s SATA derivative of the same baseline architecture is specifically tailored to support power sensitive mobile applications.

Sweet, common SATA 600

and we even come close to 3.0Gb/ps? I dont even understand why the busses get larger and larger while the medium's transfer never moves.. now SAN could probably get close to that but who has $20,000 to spend on a SAN?

With SSDs, a SATA III interface makes a lot of sense. Unfortunately, most of the SSDs that are available still use the old IDE interface, but more and more SSDs are apearing that use SATA. Now if only they used SATA III.
When SATA III is available for motherboard designers at a comparable price to SATA II (as it will be eventually) why not go with SATA III? I don't see the downside. Sure; right now it is an expensive and high-end technology, but that will change.

Uhh, not really. SSDs are known for their seek times, not transfer rates. I thought the same thing til I came across this:

With increasing download speeds, it's essential for harddrives to get faster.

yeah right with increasing download speeds huh i'd like to see that try and saturate the SATA II bus NOT gunna happen anytime soon unless you got your very own fibre optic cable link to the net with no restrictions on the speed and bandwidth i still dont know why they went to SATA II from SATA I there still isnt a HDD today that can continuously pump 300MBs in either direction so all i can say is bollocks to SATA III untill HDD manufactures get there hardware upto speed its just another marketing hype / ploy to get your money
