SSD Performance In The Office: Nine Applications Benchmarked

A number of metrics are used to quantify storage performance. If you're a regular Joe, you have to be wondering how such dry terminology can apply to office work. Rather than telling you, we're going to dissect several routine computing tasks.

According to Cisco, global Internet video traffic surpassed global peer-to-peer (P2P) traffic in 2010, and by 2012, Internet video will account for over 50 percent of consumer Internet traffic. Amazingly, that number does not include the amount of video exchanged through P2P file sharing.

This underscores the pervasiveness of streaming video. Here at Tom's Hardware, we often need to throw technology-related content onto YouTube for reviews and news posts. For others, this task may be more personal than professional. Either way, it's clear that content creation is a daily fact of life.

That's certainly the logic behind Intel's decision to dedicate a block of silicon on its Sandy Bridge-based processors to accelerating video encode and decode. Dubbed QuickSync, the company makes it possible to transcode an entire unprotected Blu-ray movie in under 20 minutes. We already took a very thorough look at output quality and found Quick Sync to be surprisingly good. For more information, read Video Transcoding Examined: AMD, Intel, And Nvidia In-Depth.

In our trace, we transcode an unprotected Blu-ray video clip using the default 720p profile for the Apple iPad with CyberLink's MediaEspresso. We didn't record the time it took to load the application, but we did record 858 MB worth of reads (158 MB more than the size of our original video file). The extra data is attributable to the application's libraries and various other file dependencies for the transcoding task.

We see higher queue depths, though fewer than 1.6% of all operations occur above a queue depth of 32. Even then, we never see any operation queued more than 62 deep. As for transfer size and seek distance, our trace reflects what you'd expect of a video oriented workload: 128 KB transfers accessed sequentially.

I/O Trends:

  • 30% of all operations occur at a queue depth of one
  • 56% of all operations occur between a queue depth of two and six
  • 91% of all data transferred is sequential
  • 75% of all operations are 128 KB in transfer size

    Nice escape, Tom's... I was wondering "hmm, what kind of torrent will they download, 95% of them are copyright infringement"... nice :D And a good article, too - maybe now I can convince some of our "office-only-don't-need-fancy-hardware" clients to switch to SSDs, esp. considering the HDD price increases.

    I want an SSD so bad I can taste it. The biggest problem for me is Price and Size. For my system drive I would need at least 500-600 GB and these sized SSDs are way to much money. My Steam folder is like 280 GBs alone. I know alot of you are going to say just put Windows and the most critical apps on the SSD and the rest on my 1TB drive but that defeats the purpose in my book. I want all my apps to benefit from the SSD especially if I am going to invest so much money into it. Here's to hoping the prices come down and fast!

    Better question: which SSD is more affordable, and which is more... reliable?

    SSD's are meant for holding only your operating system and a few key applications you can't live without. All your data/media should be stored on a regular, large hard disk.

    Unless you are working with huge files like pictures and videos, there isn't much a need for a huge SSD. A pair or HDD in RAID combine with a SSD can give you even better capacity and speed. I think most consumers are better with a 90-120GB SSD and a nice large HDD. I got an alright 120GB SSD for $120 w/ rebate. A good 120GB SSD cost about $180-$220. Laptops can hold two drive if your replace your dvd drive which most people rarely use. Once you get a SSD, it is hard to go back.

    Your office is apparently far different that the ones I service :p At least you got a virus scan and MS Word typing in there.

    I suppose I can see some inexpensive reliable SSDs in office machines in the near future, mostly to reduce the failures connected with mechanical drives and speed up boot times and installation times.

    Office computer, files on server.

    SSD not really appropriate.

    Unless by office computer you mean where you have the only computer in the office, or files do not need to be shared around the office.

    Given the amount of work people do who open large files (where an ssd may be appropriate), they are too small/too expensive to be justified.

    Example, large 3d CaD drawings, spend extra money on them loading faster, lose funds for better overall computer (graphics especially).

    I've got a C300 in my work pc, and I have to say I'm disappointed. Not by the performance itself, but the overall result. Productivity went DOWN after the upgrade, as the size of the thing simply isn't adequate. You spend more time cleaning up and moving data than you do actually working. And I even had to move all my virtual machines to usb. That didn't exactly speed up anything either. Replacing a 750gb drive with a 120gb ssd simply isn't viable.

    I find it ironic that the only place your tiny ssd drives are good enough are in computers where speed isn't important in the first place. Until 320GB ssd's can compete with regular magnetic drives, it isn't an option to upgrade.

    Imagine the added cost of upgrading the 2442 registered clients to ssd drives! About half could make do with a 120GB drive, and the rest would need at least 160GB and possibly bigger.

    That's an expense you can't possibly gain in productivity.

    Replacing sas drives with ssd's might make sense for your database or vmware/hyper-v systems, but it isn't going to make much sense on the majority of workstations.
