Adaptec to Demo 6600 MB/s Bandwidth Over PCIe 3.0

Adaptec today said that it will be demonstrating an interface capable of reaching a sustained data rate of 6600 MB/s.

The technology will leverage PMC Sierra's 24-port SRCv RAID-on-Chip with a PCI Express 3.0 interface. According to Adaptec, the new PMC RoC can support twice the bandwidth of a previous generation RoC, with twice the bandwidth on the PCIe interface and three times the bandwidth on the SAS interfaces.

There was no information which server platform the demonstration will be based on, or whether demonstration will include hard drives or solid state disk drives. However, it appears that Adaptec will become the first company to offer a 6Gb/s SAS RAID controller based on PCIe 3.0.

Adaptec will be showcasing the technology at CeBit at the Storage Pavillion. CeBit will be held from March 6 to 10 in Hannover, Germany.

    Now that is what I need, tired of sluggish onboard sata raid controllers that produce lag on top of already lagging mechanical drives while I am editing videos or multi boxing wow X.X

    It would have to be SSDs. How else could you get 6600 MB/s from 24 drives. You need to get ~275 MB/s from each drive, and you can't get that from a HDD.

    Doesn't this mean we might some day have PCIe 3.0 SSDs delivering 6600 MBps?

    How long until Intel incorporates this new standard into their SSD's?

    It's also good to see new PCIe 3 stuff coming out. PCIe 2 and USB 2 will soon be old, dated and eventually obsolete.

    SAS Expanders? Depends on the architecture and how they are getting 24 ports (is it 8 native with expanders?). LSI can do 3400MB/s with 24 15K SAS drives using expanders on their 8 port cards. Seagate Savvio drives are rated at 200MB/s on the outer rims.

    Genius! Who else would ever predict technology getting obsolete.

    6.6GB/s.... Darn....

    I was hoping is was going to be 9001MB/s......

    PCI Conventional is still hanging around, and there are some manufacturers that still produce PCI-C cards instead of PCI 2.1 1x.

Its only people with more money than they know what to do with that can afford this type of crap that actually saturates the bus. And USB 2 was obsolete before it even came out, it was just the best thing out at the time so people put up with the slow speeds.

    We already have PCIe SSds faster than that, OCZ has a 7200MB/s PCIe 3.0 SSd.

    We have 48 3.5" bay server chassis' right now, two HDDs per port (SAS isn't SATA, it supports MANY drives per port) and no problem. Some high end hard drives can go in excess of 200MB/s on the outer edges of the disks, specifically some 15K RPM drives. I bet a 7200 RPM 4TB drive could too since the 5400RPM 4TB drives can go in excess of 160MB/s, it's just a matter of building a 4TB 7200 drive.
