Performance: What Changes?
So do things seem faster using the SSD versus using the hard drive? Yes and no. I noticed that when Windows Live Sync (this was tested before the current beta came out) first loads and does it's scan of the monitored folders to see what's changed (which involves scanning 30,000+ files), it moves through them faster than the hard drive. In retrospect this is something I should have timed with a stopwatch. I also noticed that when using Picasa, the SSD was much faster at scanning for new images, creating previews, and especially displaying thumbnails as I move through my albums.
There was virtually no improvement in battery life as far as I could tell - I ran my Lord of the Rings Extended Edition playback test, and by the 2 hour 51 minute mark the V13 was down to 2% battery life. In previous tests, it made it to the 2 hour 46 minute mark with 5% battery life. Modern mechanical hard drives are very frugal with power, so even though SSDs use even less power, the biggest hit on battery life is the screen, followed by the CPU and chipset. Switching to an SSD won't enhance the battery life on your laptop, regardless of what the marketing says, unless you have a very old, very power-hungry hard drive.
Next, I updated the Windows Experience Index (WEI) rating on the V13. The hard disk score went from 5.9 to...a 5.9. Huh? Not what I was expecting, but this was my first SSD experience, so I asked my contact at Imation what the deal was. They said that the WEI is heavily weighted to random I/O performance, and that in their opinion, sequential access is more real-world relevant.
Figure 2: The PCMark Vantage numbers.
That led me to try a more comprehensive test: the PCMark Vantage Suite. The overall score on my Dell Vostro V13 was 2681 PCMarks with the Seagate hard drive; after installing the Imation 128 GB SSD, it went up to 3102 PCMarks, a 15.7% improvement. Looking directly at the hard drive test suite, the score went from 3953 PCMarks(with the Seagate hard drive) to 8445 PCMarks with the Imation SSD, a massive 214% improvement.
I also ran the HD Tune Pro 4.5 benchmark and got these results:
- Read Minimum: 77.8 MB/s
- Read Maximum: 120.8 MB/s
- Average: 106 MB/s
- Access Time: 1 ms
- Burst Rate: 54 MB/s
- CPU Usage: 26.9%
Not exactly the 230 MB/s read speeds I was hoping for - but since this is the first add-in SSD I've reviewed, I'm open to the possibility that I didn't benchmark it in the proper way to see the best sequential read speeds. I also have to wonder about the impact of a less-than-stellar CPU; the V13 only has a 1.3 Ghz single-core CPU - I wonder how different the performance would feel if it were on a powerful Core i5 system?
Boot Up/Shut Down Performance
Using the original Seagate hard drive, I benchmarked the Dell Vostro V13 from a powered off state until the Windows logon screen appeared:
- START UP: 33 seconds, 32 seconds, 33 seconds (32.6 seconds on average)
- SHUT DOWN: 12 seconds, 10 seconds, 12 seconds (11.3 seconds on average)
With the M-Class Imation SSD installed, the numbers were:
- START UP: 26 seconds, 25 seconds, 26 seconds (25.6 seconds on average)
- SHUT DOWN: 17 seconds, 16 seconds, 18 seconds (17 seconds on average)
In boot time, I saw an improvement of 27% - a significant improvement by any measure. Unfortunately I saw an even bigger difference in shut down time; a massive 50% penalty. For whatever reason, the Imation SSD imposes a significant shut-down penalty on the Vostro V13. How much real world impact does this have? Not much, given that most of the time you'll simply shut the lid of your laptop when you're finished using it. And given the lack of moving parts, you don't need to wait for the hard drive to finish writing before you put it in your laptop bag. Having an SSD really changes the rules, but I as still disappointed to see that shut-down penalty.
One thing to note: the Imation SSD doesn't yet support the TRIM function; that will be enabled in an upcoming firmware release, but it's been quite a few months since I was told that and there's still nothing released.
An immediate benefit of installing the Imation SSD in my Dell Vostro V13 was the complete lack of noise and vibration; both the Dell V13 and the HP dv2 I have are very thin laptops. And guess what happens on very thin laptops? You can feel the hard drive vibrating under your hands. It's not something I've noticed with any laptop prior to these two, so it's definitely related to the sub one-inch thickness. And on those ultra-thin laptops, because the hard drive is so close to the surface of the laptop, you can tend to hear it as well - switching to an SSD completely eliminates the noise. It might not be something that would irritate most people, but I'm extremely happy switching to an SSD fixed that issue.
And let's not forget heat as well; taking out a heat-generating hard drive also cools down the palm-rest area on the laptop, and cuts down on how often the fan has to kick in. My Dell V13 is literally completely silent in a silent room when operating. I have to put it right up to my ear to hear the internal fans. The Imation SSD makes this possible.
The start-up/shut-down numbers above were from the first few days of use; how does it perform now after several months? Start up times remain virtually the same (25 seconds, 25 seconds, and 26 seconds), but shut down times have gotten even worse (27 seconds, 39 seconds, 26 seconds). I'm not sure what process Windows 7 is running at shut down that the SSD would be so much worse at than a normal hard drive, but there's certainly something odd going on there. Because I tend to shut down my V13 and immediately put it into my laptop bag, this isn't an issue for me personally.
And what about the limitation of only 128 GB of storage? That's a bit harder to adapt to - I use Windows Live Mesh (formerly known as Windows Live Sync) to keep my documents, photos, and workspace folder. Combined, that's about 70 GB of data, and it grows bit a by more every week. At the moment, I have about 23 GB free if I empty the Recycle Bin and that's a comfortable amount of space for Windows to operate in. But when I start to get below 15 GB, I'll have to start to make sacrifices about what I carry with me on my laptop. Here's hoping that by that time, 256 GB SSDs will be somewhat affordable. I somehow doubt it though...
Wrapping it up...
So is the Imation M-Class SSD worth the price of admission? It's not as clear cut as I first thought it would be. I've had the benefit of using the Imation SSD in my V13 for a few months now, and while I really like the noiseless and heat-free advantages I mentioned above, I didn't see the performance increase I was expecting. Given that the price is still north of $300, and that 128 GB of storage may require some sacrifices, this isn't a slam-dunk product; you'll need to decide if eliminating noise and heat is valuable enough as the primary benefit (the faster boot time doesn't hurt either). If you're looking for just the drive itself, you can save a few bucks by skipping the bundle.
