From the latest pcper podcast, their storage guy teased it. Apparently review samples are out. Sites are under NDA, meaning reviews are to be released very soon, but he said it's impressive and when asked if it was, 'If you can't beat them, join them' He made no comment.
It probably is Sandforce driven. I think Intel maybe done making controllers. Frankly the G1, G2, G3 (320) Intels are just improvements and not new controllers. Neither is the 700 series. I think Intel sees no need to Conroe performance. I agree that SSDs are held back by SATA interface/controller latencies. Sequential performance is beyond what we need. It's the latency they need to work on.
PCIe interface is the future. It's available on laptops and desktops. PCIe straight to the controller without the SATA in between is a great solution to removing SATA latency and bandwidth. OCZ's Kilaminjaro SSD is a great example if that can be seen as a drive on bootup without drivers. Luckily with UEFI BIOS this can be possible. Yes, I used OCZ and great in the same sentence.
Intel maybe done with controllers and is very happy selling chips. They scored another record profit. I kinda miss the back to back AMD beats Intel... Intel beats AMD days.
