No need to get upset. You specifically wrote that we should look at reviews about the Vertex 4. I was responding to your request.
As for newegg vs. amazon, I used newegg because they usually have the largest collection of customer SSD reviews and I have used them before. But since you asked so nicely, I just applied the same quick and dirty method to amazon SSD reviews (I have not spent much time going through amazon reviews before, so I could have missed something, but I included my counts below and corrections are welcome):
Code:
3.9% = 3/76 Samsung 840 + 840 Pro
5.6% = 39/702 Samsung 830
7.3% = 16/220 Intel 330 + 335 + 520
9.5% = 39/411 OCZ Vertex 4
As you can see, there are not as many reviews on amazon as there are on newegg. But if we take the previous numbers from newegg (I merged the Intel models together and added the 335)
Code:
5.2% = 32/620 Intel 330 + 335 + 520 (Sandforce)
6.4% = 91/1411 Samsung 830
7.0% = 15/214 Samsung 840 + 840 Pro
12.2% = 82/673 OCZ Vertex 4
And combine them with the amazon numbers, we have:
Code:
5.7% (4.1, 7.3) = 48/840 Intel 330 + 335 + 520
6.2% (5.1, 7.2) = 130/2113 Samsung 830
6.2% (3.4, 9.0) = 18/290 Samsung 840 + 840 Pro
11.2% (9.2, 13.1)= 121/1084 OCZ Vertex 4
I've included the 95% confidence interval in parentheses.
I did not spend much time collecting and analyzing this data -- as I said before, this is quick and dirty. Someone with more time might go through the reviews and throw out any that are obviously not about the product (eg., review of the retailer rather than the product, or reviews of a different product). Perhaps add other refinements. I'm not interested in spending more time on it...I'll just wait for the hardware.fr return-rate numbers to come out next year.
