  1. Earlier this week, Western Digital debuted the fruit of a partnership with SanDisk: a line of solid state hybrid drives bearing its "Black" branding. In light of the announcement, WD vice president Matt Rutledge recently discussed with The Tech Report...

    5400RPM :(.

    Sounds good for standalone system use but useless for large scale random access such as database servers where the "highly utilised" data is not isolated (e.g. hits more data than can be fit in the cache). E.g. a 100GB+ database. Or a database server that has many smaller databases that total significantly larger size than the cache.

    For a game system it does sound interesting. You'd have cache misses on initial loads but after that, things should be good. The SLC part sounds pretty important - MLC cache of that size surely would wipe out write life pretty quickly in such a small cache size.

    Yeah, this is great for game systems and good for budget oriented performance systems. Too bad the platter is 5400RPM though.

    Yes curious decision. Benchmarks will be interesting...
  6. A real multi-hybrid HDD should have:

    1.- 16 to 32GB of MLC Flash memory for read cache
    2.- 4 to 8GB of SLC Flash memory for write cache
    3.- 128MB to 1GB DRAM of main cache
    4.- 500MB to 2TB @7200 RPM of storage disk
    5.- SATA III Interface, and
    6.- tuned for random R/W operations instead sequential R/W Data Throughput !

    Please give that and I'll be glad.
    :)
  7. Fe de erratas:

    4.- 500GB to 2TB @7200 RPM of storage disk

    sorry
    :p

    I'd rather have an SSTD, an SSD / Tape Drive hybrid. If RPMs don't matter, why not just go for the biggest and slowest storage + an SSD?

  9. My 2x Vertex 3 MAX IOPS in RAID 0 are laughing at this ...

    Good for you!! You either have allot of money or nothing near the storage capacity of this solution. Besides, this solution is meant for a single drive solution. A solution that provides near dedicated SSD speeds and near mechanical storage capacities, all in one drive. Take your twin Vertex's and enter them into a related topic.
