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.

    That connector in the middle of the board and the mounting holes makes it look like they could stack a daughterboard with additional controllers and flash onto this unit.

    pci-e x4 is still mostly used in servers... And that connector in the middle of the board is probably used for flashing the firmware.

    no, i agree with zdw, it indeed appears to be a daughter-board interface. why would they have such a wide mounting area for a firmware update board and who would you need a firmware update board in the first place? it's PCIe, plug it in and the firmware update tool will find the device id, much like it would search the SATA channels. it is doubtful its a diagnostics port. however, if it isn't an expansion interface, it might not exist on the final product, either.

    I am thinking connector for battery/supercapacitor memory failsafe.
  • johnsonx - Monday, May 31, 2010 - link

    why would it need that? it's a FLASH drive.

    I think he is correct. It is a battery port. If your remember anything about the sandforce drives one of their main features is that they cache more data to prevent excessive writing to the drive and get around some of the problems that were had in the past.

    Here is a quote taken from a blurb about a missing supercap in a consumer sandforce OCZ drive:
    "...Its only enough for a short burst, but it's enough to get the job done. This is important on SSDs more so than HDDs in enterprise. On an HDD when write caching is turned off, the last write command is lost, but the rest of your data is secure. On standard SSDs because of the nature of Flash and Flash management it is not typically possible to guarantee data integrity on sudden power loss..."

    It makes no sense to use a 60-pin connector for a supercap.
  • mindless1 - Monday, May 31, 2010 - link

    Exactly, it is definitely not "only" a battery or supercap connector. Definitely a data bus with that many pins.

    A battery or supercap connector would just be unused solder pads or holes, or a standard low cost SIP connector already soldered on.

    Why would you need a 60-pin interface for a battery? It is almost certainly an expansion port for daughtercard. See also the Fusion-io ioDrive Duo.

    pci-e 4x being for server ? any 16x will do,
    almost all board have multiple pci-e slot or Have a look at old EP45-DQ6
