back to article OCZ plays bottleneck card with new SSD interface

Flash storage maker OCZ wants us to use its proprietary High Speed Data Link (HSDL) instead of standard SATA and SAS interfaces for solid state drives (SSDs). HSDL was developed, OCZ says, to eliminate I/O bottlenecks and so enable SSDS to operate at their full potential. It can run at up to 20Gbit/s per channel, much faster …

    HDSL or HSDL

    Using acronyms twice for links isn't a good thing.

    Does this mean I nead a Hard Drive, SSD, HSDL, RAM, Cache, CPU to go back and forth. HSDL looks very specialised for applications that need the extra stage.

    More info..

    The Ibis is essentially a 4 drive RAID0 in a single 3.5" case. It uses a 4 port PCI-X SIS 3124 raid controller for the raid, which means 1GB/s bandwidth for the 4 drive RAID0.

    That is important as SAS2 can be bundled to provide 24Gb/s, or 4GB/s.

    So yeah, why use a proprietary interface when existing technology can already offer greater bandwidth?

    more bandwith...

    if this interface is that much faster than SAS/SATA, not much more expensive, doesnt have a serious knock on effect wrt the rest of the system resources and its a nice open standard, Bring it!! :)

    why not intergrate on mainboards

    i wonder why mainboards do not come with the ssd onboard allouwing higer data speed at lower cost?

      Stuff it on the MB

      I am with Mulder on this, why not stuff the link and controller on to the mother board and plug the SSD in at the same time and dump all the cables and plugs? the SSDs can be packaged in DIMMs the same as RAM making a much more logical construction

        Price and Heat

        At least for PC's, stuffing it on the motherboard just doesn't make good price sense. How many actually need SSD performance? Adding the controller and slots to the motherboard adds significant cost that directly impacts the all important base model cost.

        Heat and cache backup juice are also a concern.

        Would love to keep these devices optional, external, and hang them down into the raised floor vents...

        I don't like it.

        Trouble then is the cheap machines will offload the controller to a software driver, and that's what everyone will have. It'll be like Fusion-io, which I seem to remember became Confusion-io.

        I like SAS, it's an external and external interconnect, there's SAS expanders to make it into a packet (frame) switched network suitable for expansion drawers.

        I want it's replacement to share those same qualities.

          In the Anand article he says OCZ are trying to push this idea - with a few makers interested
