back to article LSI: Flash is just another thing, not a miracle in your pants

LSI will be a major flash player because it's treating flash as just another business extension and not a dramatic, kick-the-bucket, start-over, start-up fantasy. What LSI, a supplier of silicon to the disk drive, storage and communications markets, has seen is that it can pump flash extensions of its existing products through …

    But are they right?

    LSI has a somewhat biased view. They make RAID stuff for HDDs, and they don't want to lose the business.

    Reality is a bit more skewed. with flash for performance, you don't need as much storage on HDD, and you don't need super-fast HDDs either.

    That's bad news for LSI, but compounding things is that a few drives are better handled by motherboard drive ports with either a local RoC or just software (Especially as the movement for low-drive-count DAS is to RAID0). So LSI will not be selling a $500 RAID card in many cases.

    The good news for LSI is that they are a player in PCIe and SSD, but they don't have dominance like they do in the RAID card space.

    Oh, and a minor issue. Most SSD operate faster with motherboard connection than they do through a RAID card.

      Not sure what you mean by most SSDs operate faster than through a RAID card. A RAID card through PCI can trounce a SSD drive connected through SAS. The PCI interface is just so much faster. Look at the throughput that a Fusion IO card can put out.

        It's true that PCIe cards are faster than SAS SSD, which is why Micron just started delivery PCIe-connected SSD units to Dell. Neither of these warrants a RAID card.

        SAS-connected SSD generally are faster at the system level, with lower latency, than RAID card connected SSD.
