So, this morning I woke up to 69 unread emails in my inbox. Normally, I wake up to 3-5 emails. Most of those 69 unread emails were from a “Google Chrome Notebook Pilot Users” Google Group that I was not aware I belonged to. Many of the emails were other people asking why they, too, were receiving these emails?

Tonight, Google sent out an official email on the situation:

Earlier this morning, you may have received a large number of emails from chrome-notebook-pilot-users@googlegroups.com regarding the Chrome notebook Pilot program user forum. We apologize for this inconvenience, and you will not receive any more messages from this address. Instructions for deleting these messages are at the end of this email.

What happened? We planned to launch our Chrome Notebook Pilot forum next week to all users who had been selected for the Pilot program. Last night, around midnight Pacific time, a user discovered this forum and posted a message. Unfortunately, we had misconfigured this forum to email every post to every member. Thus, the first post started an avalanche of responses. Some messages were unsubscribe requests, others were thoughtful comments or questions, but all of them were emailed to every user. We have since deleted this group.

We’ve created a brand new user forum, which you can sign up for here:
https://groups.google.com/forum/#!forum/chrome-notebook-pilot

Rest assured: you will not be added to this forum unless you sign up using the link above.

The goal of the forum is to provide a centralized place for Pilot users to share their Chrome notebook experiences and tips. In addition, with a centralized forum, our team can more effectively respond to your questions and feedback.

If you are receiving this email and have not yet received a Cr-48, you should be hearing from us soon. Again, our apologies for the flood of emails, and we hope you will join us at the new forum.

Oh, Google, of all companies you should know that if you leave something out in the open someone WILL find it! At least it makes for some entertainment.

Its been one month, today, since I first received my Cr-48. So how has the Cr-48 changed my life in the past month? Well, to be honest, I barely use it anymore. It comes with me to work everyday but, due to the limitations of Chrome OS, I find myself almost always going to one of my other machines because I need to do more than the Cr-48 will allow me to do.

The included 3G has been quite helpful. I’ve used it on a few onsite jobs at work that don’t have wireless and its been a big help. Its also a great go-to machine for quickly looking something up or browsing on the go. I used it at the airport while waiting for my brother and his wife to arrive. I used it at the hospital while waiting for my mom to finish an appointment. For these types of situations, the Cr-48 is perfect. But not because of Chrome OS, but because it has an internal 3G modem.

The Cr-48 has its purposes, but, unfortunately, those purposes are still too limited for me to be able to consider the Cr-48 my everyday machine. Whats interesting is I had this same feeling when I originally tried out Google Chrome (internet browser) a few years ago, and now its the only browser I’m comfortable with using. Hopefully, one day, Chrome OS will be perfected enough to be an everyday go-to system.

Today I ran into a post on a forum I frequent regarding whether or not it was damaging to put your Windows pagefile (or Linux swapfile) on an SSD. The argument goes something along the lines of “Lots of quick reads and writes could damage the SSD over time and decrease performance”.

So I began researching. What I found is that many, many forum users believe this to be true. However, I could only find one example of actual research done on the subject.

The Microsoft Developer Network Blog has done research into the topic by looking at pagefile activity.

Should the pagefile be placed on SSDs?
Yes. Most pagefile operations are small random reads or larger sequential writes, both of which are types of operations that SSDs handle well. In looking at telemetry data from thousands of traces and focusing on pagefile reads and writes, we find that

  • Pagefile.sys reads outnumber pagefile.sys writes by about 40 to 1,
  • Pagefile.sys read sizes are typically quite small, with 67% less than or equal to 4 KB, and 88% less than 16 KB.
  • Pagefile.sys writes are relatively large, with 62% greater than or equal to 128 KB and 45% being exactly 1 MB in size.
  • In fact, given typical pagefile reference patterns and the favorable performance characteristics SSDs have on those patterns, there are few files better than the pagefile to place on an SSD.

    After half a dozen pages of Google search results I was not able to find another reputable website that covers the topic. About the closest I could find was Tom’s Hardware stating:

    Windows is smart enough to store data from minimized applications or idle applications in the swap file so that active processes can access more RAM. The disadvantage of this solution is obvious. The performance of a mechanical hard drive is only a fraction of the throughput realized with memory modules. Solid state drives (SSDs) are an improvement, but the general problem remains. Frequent swap operations are poison to an SSD, possibly decreasing its speed.

    Possibly decreasing its speed. Tom’s Hardware is careful not to say one way or the other as they haven’t seen any research either.

    Essentially what it comes down to is who to believe. Would you believe MSDN with their research into pagefile activity and potentially risk damaging your SSD? Or would you believe the hundreds of forum posters who claim that it will indeed damage your SSD but have no research to prove it? I think this one comes down to a situation of “Can you afford to replace your SSD?”. If the answer if “yes” then relish in the performance benefits. If your answer is “no” then I would play it safe and put your pagefile on a separate hard drive.
