Debunking a Rumor about Clean Installs on SSD's

post #1 of 7
Thread Starter 
I wrote this on my blog, but since I can't link to my own blog, I thought I'd share my results here.

Anyone that has upgraded to an SSD has heard about it. The first thing you do is do an online search for something like, "Transfer OS to SSD". Most of the time, you'll start reading about how to do it, but by the time you figure out how to do it correctly, you could have just done a clean install and re-installed all the software you had before.

Sidetracking a bit, to actually transfer your OS and installed applications to a new drive, I recommend Acronis Home True Image. I currently use the 2010 version with the Plus Pack. What the Plus Pack has is the option for doing a "Universal Restore". That means if you were also upgrading your Motherboard and CPU to something that uses a different chipset and memory controller (for instance, an AMD CPU to an Intel CPU), chances are that you're going to need to do a Universal Restore.

You can't just create a backup image of your original disk and restore it to your SSD, because it's loaded with drivers from your previous CPU/Motherboard. You can do so if you use Universal Restore, because it doesn't transfer any of your critical drivers over...

Okay, enough sidetracking, that's not what this article is about. What this article is about are people saying that a clean Windows installation and all your other software is better for your SSD than restoring a cloned image to it. We're going to try debunking that rumor, as I've never seen anyone actually try measuring the performance difference between the two.

Update: Sean Webster, a Storage Editor from Overclock.net mentioned that, "With a HDD to a SSD, there were a few other things to look at, such as alignment, system services, and adjusting the size of the current HDD partition, etc." Therefore, I added in an additional test to include a HDD clone to a SSD restore and compare the differences.

The test set-up:
  • Processors: Core i7 2600K/2700K @ 4.9 GHz 100 x 49
  • Motherboard: ASUS P8Z68-V Pro
  • SATA Port: Intel 6GB/s
  • SSD: Patriot Pyro 120GB
  • HDD: Western Digital Caviar Black 1TB
  • Power Supply: Corsair AX1200
  • OS: Windows 7 Ultimate 64-bit
  • Software: CrystalDiskMark3.0.1, HD Tune Pro 4.6.1, Acronis Home True Image 2010 Plus Pack


The sequence of tests:
Measure the SSD performance with a newly formatted SSD
Install Windows 7 Ultimate 64-bit and install drivers and Windows Updates
Boot as a secondary drive and make a back-up image of the drive
Measure the SSD performance of a fresh Windows installation
Restore the back-up image of the drive on the SSD
Measure the SSD performance of a restored Windows installation

Possible issues:
Since I don't have two new SSD's that have never been used, I'm using a single used SSD and re-using it, slower benchmark results may occur on the restored Windows installation. At any rate, we're expecting slower benchmark results anyway on the restored Windows installation, so if we don't, the rumor should be debunked.

Newly formatted results:
368

521

521

521


The Fresh Installation SSD to Restored Image SSD comparison results:
273

Using CrystalDiskMark, we find the read speeds minimally slower, but the write speeds are slightly faster with the Restored Windows Installation compared to a Fresh Windows Installation.

263

Using HD Tune Pro's Read Benchmark, we find that the read speeds are actually minimally faster with the Restored Windows Installation.

263

Using HD Tune Pro's File Benchmark, it's difficult to see any real differences.

263

Using HD Tune Pro's Extra Read Tests, we find the differences to be minimal.

The SSD Restored Image SSD to HDD Restored Image SSD comparison results:
273

We do see some slowdowns occurring in Write speed, but it's not by a drastic amount.

264

This is where it's the most interesting. You can really see the first wave of the graph being hampered in performance. Not by very much, but it's definitely noticeable.

263

This graph is more difficult to notice any real differences.

264

On this one, we can see some minor differences.

Conclusion and Thoughts:
Is the rumor debunked? Well, in a way, not really, but also, yes.

Looking at the comparisons, there's absolutely no real difference doing a completely new Windows Installation on an SSD compared to cloning and restoring your existing Windows Installation from another SSD onto an SSD. However, there is a slight detriment when doing so from a HDD to a SSD.

Computer Ed from the Computer Ed Radio Show does mention something worth noting. Over time, you start to build up a lot of junk over your hard drive. A lot of unnecessary installs, bad driver updates... stuff that may not be noticed everyday, but can create little glitches throughout the system. A clean install gives you a fresh start, and also may trim some storage room by not installing software you no longer use.

So, if you would rather not waste hours re-installing everything, just use software to backup your existing disk and restore it to your new SSD within a matter of minutes. You won't see much of a performance loss as you would think, even when cloning from a HDD to a SSD. Computer Ed does bring up a good point with doing a clean install, too. Ultimately, the choice is yours, but the data is here if it helps guide you in your decision.

All you did was make a system image of the OS when it was installed on a SSD and restore it back to the SSD...

With HDD to SSD there are a few other things to look at such as alignment, system services, and adjusting the size of the current HDD partition, etc.

I guess that's true, I didn't think of that, lol. I'll have to try an actual HDD to SSD transfer. Thanks!

thanks, i was looking to upgrade my ssd and wanted to transfer and not have to install all over

there's one thing.. can acronis delete in the process the 100mb partition window auto-created?, i just 't don't want it and forgot to deal with in this installation.

You can delete it before if you like with a install or repair disk: http://www.sevenforums.com/tutorials/71363-system-reserved-partition-delete.html
