PCIe based SSDs have been reserved for enterprise use ever since their introduction. Generally limited by pricing, even OCZ's own forays into the PCIe SSD market have been targeted at enterprise customers. That may all change with today's announcement. Meet the RevoDrive:

This PCIe x4 card takes a pair of SF-1200 controllers and RAIDs them together, giving you roughly the performance of two SF-1200 SSDs but on a single card. Through some unique component selection OCZ aims to keep costs around 10 - 20% more than a single drive. Obviously you lose TRIM support and the overall performance should be no different than a pair of SF-1200s in RAID (on a good controller/chipset), but if you need PCIe this may be an option.

    also, i think you can't use it to boot from,
    or at least PCIe SSDs couldn't do that the last time i checked.

    There is a 32pin EEPROM in the upper left of the card, so it is most likely bootable

    Also right above both of the SandForce controller sits a quite large rectangular white thing maked "X1 and X2" on the PCB, I'll take a guess those are x-caps

    And lastly there are many unpopulated headers on the board, for example J3 and J5 between the SandForce controllers, can most likely be used for diagnostics and firmware flashing (disaster recovery)
    There are also many contacts points named "TP" this is most likely a development board with extra stuff for diagnostics

    The firmware is probably flashed to the card via the PCIe bridge of course, like you do with any other RAID controller

    And the big connector in the middle with 4 holes surrounding it is most likely for capacity expansion via a daugtherboard

    I think there is confusion between PCI and PCIe going on. Old PCI shared a single bus for all traffic, PCIe has dedicated lanes for each slot back to the southbridge (or such).

    Also, "raw" PCIe SSDs cannot be booted, but this SSD and any other with RAID functionality can be a boot device -- it's just a RAID card as far as the system is concerned, it doesn't care what is beyond the Intel RAID controller.

    There are a whole lot more pci express lanes on some controllers than most people need though. Even graphics cards only lose a small percentage of performance running at 8x 2.0 instead of 16x 2.0 so even if you used some of those lanes (iirc you have to go from 16 to 8) it would be fine.

    Yes, I ment what I said about Sata II. If the current gen SSDs are bandwidth limited the actual performance (at least read performance) of SF1200 might be higher than we are currently seeing, this this card having a potantial to be faster than 2x of current SSDs.

    As for trim, I'm not sure there even is such a thing as trim for pci express devices. Without looking into the driver model of these cards I see no reason for the driver not to allow trim messages to pass down though, by telling the OS that yes, this is a drive that supports trim. After all, this is not a software raid device that is detected as two drives in the OS so the problems with raid 0 with two SSDs don't really apply here. Just issues with trim + pci express in general.

    TRIM, obviously, is a feature of SATA. If this thing doesn't look like a SATA disk then TRIM is beside the point. Reply

    How can they possibly reduce the price of a drive with 80-90% by adding a Raid chip?

    Does Anand mean 10-20% _MORE_ then a single drive?

    Either it's been updated, or that's exactly what he said. Reply

    The way the screw holes are mounted behind the center port there it looks like it is designed to hold something heavy and mounted towards that end. Expansion sounds right, but it may be a diagnostic port as well.

    Who knows if this will stay when it comes to popular distribution or if this was the tinker-toy of the developers......

    If the daughter card has 2 additional SSD's and a supercap to prevent data loss during power outage, then the ability to plug 4 such cards into my motherboard would make an excellent boot drive with read speeds around 4.4 GB/sec in Raid (16 SSD's X 275 MB/sec read per SSD average)

    So far so good! If I am then booting up in, for example 0.63 seconds but want to shave a few more milliseconds from my boot time, I don't think I can push the buttons on my stopwatch fast enough to verify if my Boot Tweeks are working or not

    Serious Gamers really need to be ready to play by the time they release the power button on their computer after all

    I just hope Intel has a 16 core CPU to handle the overhead by the time I can afford these and 2 Dual GPU Fermi Cards
