The SSD Diaries: Crucial's RealSSD C300by Anand Lal Shimpi on July 13, 2010 12:39 AM EST
Overall System Performance using PCMark Vantage
Next up is PCMark Vantage, another system-wide performance suite. For those of you who aren’t familiar with PCMark Vantage, it ends up being the most real-world-like hard drive test I can come up with. It runs things like application launches, file searches, web browsing, contacts searching, video playback, photo editing and other completely mundane but real-world tasks. I’ve described the benchmark in great detail before but if you’d like to read up on what it does in particular, take a look at Futuremark’s whitepaper on the benchmark; it’s not perfect, but it’s good enough to be a member of a comprehensive storage benchmark suite. Any performance impacts here would most likely be reflected in the real world.
The overall PCMark vantage score puts the OCZ Vertex 2 ahead of the C300 by only 3%. Move to a 6Gbps controller and the C300 is now on par with the Vertex 2. Either way you look at it, general desktop performance should be about the same between the two for workloads exemplified by PCMark Vantage. The real world advantage over the Corsair Nova is 12.5%, just enough to be noticeable. This also reflects what I’ve seen in my own experiences with these drives as a user. There’s a noticeable performance increase between the X25-M/Indilinx class of SSDs and the new guard. It’s not earth shattering, and no where near the gap you see between SSDs and HDDs, but it’s noticeable on fast systems.
The memories suite includes a test involving importing pictures into Windows Photo Gallery and editing them, a fairly benign task that easily falls into the category of being very influenced by disk performance.
The TV and Movies tests focus on on video transcoding which is mostly CPU bound, but one of the tests involves Windows Media Center which tends to be disk bound.
The gaming tests are very well suited to SSDs since they spend a good portion of their time focusing on reading textures and loading level data. All of the SSDs dominate here, but as you'll see later on in my gaming tests the benefits of an SSD really vary depending on the game. Take these results as a best case scenario of what can happen, not the norm.
In the Music suite the main test is a multitasking scenario: the test simulates surfing the web in IE7, transcoding an audio file and adding music to Windows Media Player (the most disk intensive portion of the test).
The Communications suite is made up of two tests, both involving light multitasking. The first test simulates data encryption/decryption while running message rules in Windows Mail. The second test simulates web surfing (including opening/closing tabs) in IE7, data decryption and running Windows Defender.
I love PCMark's Productivity test; in this test there are four tasks going on at once, searching through Windows contacts, searching through Windows Mail, browsing multiple webpages in IE7 and loading applications. This is as real world of a scenario as you get and it happens to be representative of one of the most frustrating HDD usage models - trying to do multiple things at once. There's nothing more annoying than trying to launch a simple application while you're doing other things in the background and have the load take forever.
The final PCMark Vantage suite is HDD specific and this is where you'll see the biggest differences between the drives:
In the HDD suite itself, OCZ holds the clear advantage with the Vertex 2 showing up 15% faster than the 128GB RealSSD C300. Moving to a 6Gbps interface basically levels the playing field between the two.
