Micron's RealSSD P400e: Affordable SSD Storage For The Enterprise?

By Andrew Ku

Enterprise-class SSDs use costly SLC NAND or, more frequently, eMLC flash. But Micron's RealSSD P400e raises eyebrows by using low-cost MLC memory. Does this make sense on an SSD fighting for the affections of data center managers with read-heavy apps?

    I wonder if the poor performance is part of some mechanism that ensure higher reliability. Maybe lower read and write voltage increase endurance but take longer to populate the cell with the appropriate charge level.

    Just sayin'.

    Release Date: 04/11/2012

    Firmware for the m4 SSD is being updated from version 0309 to 000F. The m4 is updatable to this new firmware starting from versions 0001, 0002, 0009, or 0309 in a single step. If updating from an early version directly to 000F, all interim improvements will also be include.
    Changes between version 0309 and 000F include the following changes:

    Improved compatibility with certain SAS expanders and peripheral RAID cards.
    Improved throughput stability under extremely heavy workloads.
    Improved data protection in the event of unexpected, asynchronous power loss.
    This firmware update is recommended for all drives currently in the field if the end user is experiencing any of these symptoms.

    m4 firmware updated to a newer version.

    Seems like the perfect SSD for a third-rate data center and not mine.

    If SoftLayer (f/k/a ThePlanet) wants to lower their standards then good for them, and perhaps they need yet another law suit or reevaluate their published up-time with some more asterix *.

    The only thing that is important for me is full disk encryption in desktop environment. Unfortunately Intel completly forgot and since Q66 chipset there is no mainboard supporting FDE with SSDs. Q77 probably could support it, but there is no BIOS that has "hard disk / ATA password" option. Intel, wake up!!!

    Not impressed at all. I dont really see one redeeming feature this drive has that would get it chosen over many other SSD's on the market.

  • Is it just me or do I notice that we really need to SAVE SLC from extinction? I mean, naturally high performance (compression or none), better temperature control, and higher longevity are the greatest features of SLC - good for the environment, pocketbooks, and peace of mind long term. Anyone?
