    I have requested and been requested to test several. As a result, my relationship with companies has grown very close.

    If I have a notebook with the Intel ICH8, will there be a real performance difference between mlc and slc? Will the chip be the bottleneck?

    No, there should be no deviation from the posted benchmarks for each.

    I guess Intel disagrees. They're ramping their 200MB/s read 100MB/s write ONFI 2.0 160GB drives this year specifically to make a larger NAND market and get SSDs affordable. I work for the company that makes these chips for them, and they're constantly increasing in density.

    Other than that, these are some good basic descriptions of flash.

    Edit: I forgot it was EMC who is using our SLC in their drives. I haven't been able to find details about what these will use, just that they're the 8Gbit/16Gbit chips with at least 100,000 write cycles, though one press article said it was MLC. If so, that's good endurance for an MLC.

    Just was wondering why the STEC models are already getting 200/100 throughput in their current IOPS drives on FC and SAS interfaces (I think they are still SATA1 only so it would be closer to 135/100) with a max capacity of 256GB. I hadn't even noticed their recent IOPS update until a thread yesterday made me check their current lineup.

    Are they doubling the # of chips and allowing full controller access thus doubling throuput while increasing size?

    They don't go into great detail, and it's obviously to early to adopt anything like next gen OFNI 2.0 already even at the enterprise level.
