Real World Performance with PCMark Vantage

Next up is PCMark Vantage, another system-wide performance suite. I chose to run the whole suite rather than just the HDD test to hopefully better characterize real world performance of these drives.

PCMark

If we look at the individual test subsets of PCMark Vantage we can see the drive's strengths at work.

Memories

The memories suite for example 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 end result is a 15% performance advantage over the VelociRaptor, a 16.6% advantage over the Samsung SLC based SSDs and a 42% advantage over the 2.5" Seagate Momentus 7200.2 HDD - the X25-M is great for a desktop, but a miracle for a notebook.

TV and Movies

The TV and Movies suite shows that the X25-M won't always dominate. Here the tests are focused on video transcoding which is mostly CPU bound, but one of the tests involves Windows Media Center which tends to be disk bound. Despite the nature of the test, the X25-M competes at the top of the chart but is bested by the VelociRaptor. It's performance isn't bad, but not earth shattering. Again, compared to other notebook drives it is a dream come true.

Gaming

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 depend on the game. Take these results as a best case scenario of what can happen, not the norm. You can also see how tempting it is to opt for one of those JMicron based MLC SSDs, they perform quite well here - the test simply doesn't show the ugly side of living with them.

Music

We're back to utter domination in the Vantage Music test. Here the main test is a multitasking scenario, which SSDs do quite well in: 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 X25-M is nearly 60% faster than the VelociRaptor, around twice the speed of the Seagate Momentus 7200.2 and over 37% faster than the Samsung SLC based SSDs. When the X25-M is fast, it's very fast.

Communications

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.

Despite the inclusion of Windows Defender, the X25-M's advantage over the VelociRaptor is only 18%. I would honestly expect more based on some of my other system scanning tests, but I believe the reason we're seeing general domination and not utter destruction is that the tasks being run alongside Windows Defender are quite light on the disk. Yes, I am nitpicking an 18% victory - this drive is that good. The SLC drives do well here but are no match for the X25-M. It's in tests like this that the X25-M really earns its keep, it delivers SLC performance at a much lower cost.

The Productivity test is awesome, let me explain:

Productivity

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 seemingly forever.

Note that the test itself isn't very write intensive, so even the JMF602 based MLC drives do well here. I can attest to this as one of the things that drove me to put a SSD in my desktop was that I wanted my applications to pop up instantaneously, regardless of what I was doing. The pausing doesn't get a chance to rear its head, so all of the SSDs rule the playing field here. The X25-M delivers 2x the performance of the VelociRaptor here and is faster than every other drive. Enough said.

Intel X25-M (Kingston SSDNow M-Series) Review by Alleniv on Wednesday, August 19, 2009
Hi all,
I report this new review about X25-M, that takes in consideration a comparative with other SSDs and also with HDDs, with several benchmarks ? http://www.informaticaeasy.net/le-mi...m-da-80gb.html
Alleniv
You said this: For example, let's say you download a 2MB file to your band new, never been used SSD, which gets saved to blocks 10, 11, 12 and 13. You realize you downloaded the wrong file and delete it, then go off to download the right file. Rather than write the new file to blocks 10, 11, 12 and 13, the flash controller will write to blocks 14, 15, 16 and 17. In fact, those four blocks won't get used again until every other block on the drive has been written to once

By this i understand that a bigger capacity SSD, for instance 320 vs 160 will have more blocks and hence you will need more writes to deplete the number a write cycles the SSD was designed for. So for SSD bigger means even longer lasting. IS this TRUE ?

Samsung's new MLC-based 256GB SSD by kevonly on Friday, November 21, 2008
I hope you do some benchmark on Samsung's new 256GB SSD. Hopefully it's as good as Intel's.

RE: Samsung's new MLC-based 256GB SSD by kevonly on Friday, November 21, 2008
its read/write speed is 200/160 mb/s. Will it sustain that speed in a multi applications running environment??

SSD Test Methodology Flawed Technically Unsound by D111 on Saturday, October 25, 2008

Legacy OS like Windows Vista, XP, and Applications like Microsoft Office 2003, 2007, etc. have built in, inherent flaws with regard to SSDs.

Specifically, optimizations of these OS for mechanical hard drives like superfetch, prefetch, etc. tend to slow down, rather than help performance and is unnecessary to speed up reads in an SSD, but slow it down with unnecessary writes of small files, which SSDs are slower than a regular hard drive.

Things like automatic drive defragmentation with Vista does nothing for SSDs except to slow them down.

Properly optimized, even low cost 2007 generation SSDs test out as equivalent to a 7200 rpm consumer grade drive, and typical SSDs made in 2008 or later tend to outperform mechanical hard drives.

The tests done here have done nothing to "tweak" the OS to remove design hindrances to SSD performance, and thus, have no validity or technical merit.

The test, as presented, would be similar to installing a 19th century steam engine on a sailing ship, and observing that it is rather slow ---- without mentioning the drag and performance hits caused by the unused sail rigging, masts, etc.

See the discussion here for a detailed discussion of SSD performance tweaks and what it takes to make them perform well with legacy OS and Applications.

Fusion-IO & ioXtreme by Mocib on Thursday, October 09, 2008
Good stuff, but why isn't anyone talking about ioXtreme, the PCI-E SSD drive from Fusion-IO? It baffles me just how little talk there is about ioXtreme, and the ioDrive solution in general.

RE: Fusion-IO & ioXtreme by Shadowmaster625 on Thursday, October 09, 2008
I think the Fusion-IO is great as a concept. But what we really need is for Intel and/or AMD to start thinking intelligently about SSDs.

AMD and Intel need to agree on a standard for an integrated SSD controller. And then create a new open standard for a Flash SSD DIMM socket.

Then I could buy a 32 or 64 GB SSD DIMM and plug it into a socket next to my RAM, and have a SUPER-FAST hard drive. Imagine a SSD DIMM that costs $50 and puts out even better numbers than the Fusion-IO! With economy of scale, it would only cost a few dollers per CPU and a few dollars more for the motherboard. But the performance would shatter the current paradigm.

The cost of the DIMMs would be low because there would be no expensive controller on the module, like there is now with flash SSDs. And that is how it should be! There is NO need for a controller on a memory module! How we ended up taking this convoluted route baffles me. It is a fatally flawed design that is always going to be bottlenecked by the SATA interface, no matter how fast it is. The SSD MUST have a direct link to the CPU in order to unleash its true performance potential.

This would increase performance so much that if VIA did this with their Nano CPU, they would have an end product that outperforms even Nehalem in real-world everyday PC usage. If you dont believe me, you need to check out the Fusion-IO. With SSD controller integration, you can have Fusion-IO level performance for dirt cheap.

If you understand what I am talking about here, and can see that this is truly the way to go with SSDs, then you need to help get the word to AMD and Intel. Whoever does it first is going to make a killing. I'd prefer it to be AMD at this point but it just needs to get done.
