The Test

CPU Intel Core i7 965 running at 3.2GHz (Turbo & EIST Disabled)
Motherboard: Intel DX58SO (Intel X58)
Chipset: Intel X58 + Marvell SATA 6Gbps PCIe
Chipset Drivers: Intel 9.1.1.1015 + Intel IMSM 8.9
Memory: Qimonda DDR3-1333 4 x 1GB (7-7-7-20)
Video Card: eVGA GeForce GTX 285
Video Drivers: NVIDIA ForceWare 190.38 64-bit
Desktop Resolution: 1920 x 1200
OS: Windows 7 x64

Sequential Read/Write Speed

Using the latest build of Iometer I ran a 3 minute long 2MB sequential test over the entire span of the drive. The results reported are in average MB/s over the entire test length:

2MB Sequential Read - MB/s

Read speed is a bit lower than we're used to seeing, but at 235.7MB/s this is almost twice as fast as a VelociRaptor. In the SSD space, the SiliconEdge Blue performs like the lower end of the Indilinx drives.

2MB Sequential Write - MB/s

Sequential write speed is again much faster than any hard drive (2.5" or 3.5"), and compared to SSDs the SiliconEdge Blue is similar to an Indilinx based drive.

    I buy Intel for the Intel SSD Toolbox utility. With win7, I load the Intel chipset inf, Matrix Storage Manager and am not sure if Trim still works.

    I am happy to see WD into this market. Prices need to come WAY DOWN!

    As a great fan of the Raptor series drives, what I want from WD is the same concept in SSD: the top performance and super reliability it is. The down side of course in a VelociRaptor is its relative price - and, as expensive as SSDs still are, a comparable price for an SSD "VelociRaptor" would be extreme.

    Still, it's what I want, and I could certainly see me building a high-end system using smaller capacity WD SSD "Raptors" in Raid 0 for that extreme performance goofy people like me want to have. If I get an extra few grand handed to me, I would use larger drives, of course.

    Anyhoo, this drive is not what I want to see from WD (unless of course it really does kick reliability butt over its competitors). Hopefully by the time I build another high-end rig (just built one so it will be awhile, likely) WD will have what I want (or someone), a SSD successor to VelociRaptor mechanical hard drives.

    Great article Anand! Also thanks for reiterating the incompatibility with gen2 unibody macbook pro's and particular SSDs. Will you be able to test this SSD with your mbp?

    Anand mentioned some possible convergence between magnetic and solid state drive firmware development. Could this mean the mythical hybrid drive is down the road somewhere? With single spindles holding in excess of 300 GB and SSDs not even filling the 2.5" form factor, isn't there room for both? If not both storage types in one drive then maybe both storage types in one drive slot? Then you could have the boot drive be the super fast SSD and the advantage of cheaper, higher-capacity storage of a single-spindle magnetic drive in a single laptop. I think this dual-drive approach could be a better solution than the hybrid drive until caching in drive controllers becomes smarter.

    These drives clearly don't support NCQ, as IOPS don't scale with QD.
    The rating of 5000 IOPS is about the same as the rating of a single NAND TSOP. You can literaly get the same random IOPS performance from a thumbnail USB drive.

    Can someone explain why there's a dropoff in performance between the 100GB and 50GB Mercury Extreme SSDs in the 4K Aligned random write test?
  • cactusdog - Thursday, March 4, 2010 - link

    Oh well nothing to see here either. I dont see how they can justify the price. A SSD with a PCB and some chips should be cheaper to make than a mechanical hard drive with moving metal parts. Fair enough to pay a little extra for new tech but this is ridiculous.

    I'd really like to see performance of two 7200rpm drives in a striped RAID thrown into these charts. So please get on that.
  • 7Enigma - Thursday, March 4, 2010 - link

    I'll save you the time of waiting.

    -Sequential Read and Write: Near twice the performance of a single drive

    -Random 4K read/write: Just as bad as a single drive

    Fin~

    Going from WD's HDD naming conventions I would expect average but reliable performance from a "Blue" SSD, and that appears to be exactly what they've delivered, albeit at a ridiculously high price.

    The WD SSD I'm really interested in is the "SiliconEdge Black", a drive that will hopefully be forthcoming after their sales division puts down the crack pipe and gets serious about SSD pricing.
