AnandTech Storage Bench 2010

To keep things consistent we've also included our older Storage Bench. Note that the old storage test system doesn't have a SATA 6Gbps controller, so we only have one result for the 6Gbps drives.

The first in our benchmark suite is a light/typical 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):

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.

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.

    Yes, thank you for addressing the Vertex 2 issue.

    The sad part is that if OCZ had used their new, transparent labeling scheme from day one, they would have been praised for their transparency and all of the other companies would have been expected to rise to their standard. Instead, they waited through months of consumer and press outcry, meaning this fair and honest SKU system is merely re-earning lost trust.

    Intro page: "It's also worth nothing that 3000 cycles is at the lower end for what's industry standard..."

    I can't figure out your intent here. Is it worth noting or is it worth nothing?

    On many workstations in my company we have a daily SSD usage of at least 20 GB, and this is not something really exceptional. One hibernation in the evening writes 8 GB (the amount of RAM) to the SSDs. And no, Windows does not write only the used RAM, but the whole 8 GB. One of the features of Windows 8 will be that Windows does not write the whole RAM content when hibernating anymore. Windows 7 disables hibernation by default on system with >4GB of RAM for that very reason! Several of the workstation use RAM-Disks, which write a 2 or 3 GB Images on Shutdown/Hibernate. Since we use VMWare heavily, 1-2 GB is written contanstly all over the day as Spanshots. Add some backup spanshops of Visual Studio products to that and you have another 2 GB.

    Writing 20 GB a day, is nothing unusual, and this happens on at least 30 workstations. Some may even go to 30-40 GB.

    Only 3000 write cycles per cell is the reason why we had several complete failures of SSDs. Three of them from OCZ, one Corsair, one Intel.

    Yours is a usage scenario that would benefit more from running a pair of drives, one SSD and one large conventional hard drive. The conventional drive could be used for all your giant writes (slowness won't matter because you are hitting shut down and walking away) and use the SSD for windows and applications themselves.

    HDD slowness does matter! A lot! Loading a VMWare snapshot on a Raptor HDD takes at least 15 seconds, compared to about 6-8 with a SDD. Shrinking the image once a month takes about 30 minutes on a SDD and 3 hours on a HDD!

    Since time is money, HDDs are not an option, except as a backup medium.
