OK, To address both the Crucial M4 (being most reliable) and using Newegg reviews at the same time let me say this.
I do agree that Newegg reviews are a valuable source of feedback and should be considered. However, with complicated products like an SSD that must be installed correctly for it to work properly, the value of the Newegg reviews goes down quite a bit because there are so many brain-dead people NOT installing and setting up their SSDs correctly.
For example, when you look at the Newegg reviews on blu-ray burners they are filled with dummies who cannot comprehend that you have to have the right software in order to play blu-rays. They also think the limited bundled software should be all inclusive when it never is. They also think that for a bare burner with NO software that the software STILL should have been included. I am sorry, but these people are just ignorant.
When you talk with IT professionals with a lot of first-hand experience with SSDs they almost to a man (or woman) will say that SSDs are FAR more reliable than HDDs. BUT, they take someone with a reasonable amount of intelligence to install them because they have special requirements. I am willing to bet that a lot of the problems we hear about are from people who just don't know what they are doing and then install the SSD like and HDD which will not work.
SSDs have no moving parts and so they are intrinsically more reliable. The problems they have experienced have been in the controllers and in wear leveling. With the newest SSDs, these problems have largely been eliminated.
With the exception of possibly Intel, there is no reliable data that would differentiate the reliability of one SSD from another. Unless we start seeing a huge percentage of Newegg reviews going negative then those reviews are not the best source of feedback (though I agree it is about all we have right now).
For example, the Corsair Force 3 (non-GT) had a problem earlier and about 85% of the Newegg reviews went negative. Now that is much more reliable data than a lot of the sheer gossip and old-wives tales we keep hearing about various SSDs. I bought the Force 3 on sale and I was concerned. I called up Corsair and they agreed to trade out the Force 3 for the Force 3 GT AT NO ADDITIONAL COST. Corsair is indeed and amazing company.
SSDs are selling like hotcakes and most of the satisfied customers are not being heard from. I believe right now that SSDs are far more reliable than HDDs, they just are not as user friendly and simple to use.
It is your choice whether you want to take a chance and use an SSD and get a 500% increase in performance. Most computer professional are doing it right now in droves and they know better than anyone the risks involved. If you don't need the extra speed, stick with an HDD but don't think that you are any safer from drive failure than with and SSD, There is not proof of this at all and it is very likely you are MORE likely to have catastrophic failure with an HDD than an SSD based on what I have heard from the pros.
