AnandTech Storage Bench

Note that our 6Gbps controller driver isn't supported by our custom storage bench here, so the C300 results are only offered in 3Gbps mode.

The first in our benchmark suite is a light usage case. The Windows 7 system is loaded with Firefox, Office 2007 and Adobe Reader among other applications. With Firefox we browse web pages like Facebook, AnandTech, Digg and other sites. Outlook is also running and we use it to check emails, create and send a message with a PDF attachment. Adobe Reader is used to view some PDFs. Excel 2007 is used to create a spreadsheet, graphs and save the document. The same goes for Word 2007. We open and step through a presentation in PowerPoint 2007 received as an email attachment before saving it to the desktop. Finally we watch a bit of a Firefly episode in Windows Media Player 11.

There’s some level of multitasking going on here but it’s not unreasonable by any means. Generally the application tasks proceed linearly, with the exception of things like web browsing which may happen in between one of the other tasks.

The recording is played back on all of our drives here today. Remember that we’re isolating disk performance, all we’re doing is playing back every single disk access that happened in that ~5 minute period of usage. The light workload is composed of 37,501 reads and 20,268 writes. Over 30% of the IOs are 4KB, 11% are 16KB, 22% are 32KB and approximately 13% are 64KB in size. Less than 30% of the operations are absolutely sequential in nature. Average queue depth is 6.09 IOs.

The performance results are reported in average I/O Operations per Second (IOPS):

Once again, most users will find the SiliconEdge Blue performing like a low end Indilinx drive - but still much better than any hard drive.

If there’s a light usage case there’s bound to be a heavy one. In this test we have Microsoft Security Essentials running in the background with real time virus scanning enabled. We also perform a quick scan in the middle of the test. Firefox, Outlook, Excel, Word and Powerpoint are all used the same as they were in the light test. We add Photoshop CS4 to the mix, opening a bunch of 12MP images, editing them, then saving them as highly compressed JPGs for web publishing. Windows 7’s picture viewer is used to view a bunch of pictures on the hard drive. We use 7-zip to create and extract .7z archives. Downloading is also prominently featured in our heavy test; we download large files from the Internet during portions of the benchmark, as well as use uTorrent to grab a couple of torrents. Some of the applications in use are installed during the benchmark, Windows updates are also installed. Towards the end of the test we launch World of Warcraft, play for a few minutes, then delete the folder. This test also takes into account all of the disk accesses that happen while the OS is booting.

The benchmark is 22 minutes long and it consists of 128,895 read operations and 72,411 write operations. Roughly 44% of all IOs were sequential. Approximately 30% of all accesses were 4KB in size, 12% were 16KB in size, 14% were 32KB and 20% were 64KB. Average queue depth was 3.59.

AnandTech Storage Bench - Heavy Workload

The SiliconEdge Blue follows in the footsteps of Kingston's SSDNow V+ here and does amazingly well in our heavy workload. I'm beginning to wonder if it's the large 64MB external cache at work or something specific to JMicron/Toshiba controllers that seems to do so well in this mostly write-bound multitasking test. It's definitely the exception in the Blue's performance.

The gaming workload is made up of 75,206 read operations and only 4,592 write operations. Only 20% of the accesses are 4KB in size, nearly 40% are 64KB and 20% are 32KB. A whopping 69% of the IOs are sequential, meaning this is predominantly a sequential read benchmark. The average queue depth is 7.76 IOs.

With competitive sequential read speeds, there's no reason that the SiliconEdge Blue shouldn't do well here. Again it's just slightly behind the Indilinx based SSDs.

    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? Reply

    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. Reply

    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? Reply

    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. Reply

    I'd really like to see performance of two 7200rpm drives in a striped RAID thrown into these charts. So please get on that. Reply

    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

    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.
