How about units sales % vs rma ?
the report is about failure return rates of common hardware, focusing on giving users hints about which brands and models to get. iinm it's based on a large e-tailer in france.
actually at the beginning of the article there is a part that explained how the numbers were concluded. using google translate, it's as quoted below.

If there is an unknown during the advice and the purchase of a material, it is its reliability. Certainly the reputation of a manufacturer is there to reassure us, but from one model to another it can vary enormously and even renowned builders are not immune to a blunder!
Although past performance does not bode well for future performance, we are releasing today some of the breakdown rate statistics available to us. They cover parts sold during the second half of 2016, for returns created before the second half of 2017, ie a maximum of one year of operation. The change in the rate of breakdown over the lifetime of a product generally forms a flat U, practically flat, and these figures therefore cover the first part of their life, when the rate is high.
This type of statistics needs some retreat, so some of the products have become obsolete. Nevertheless, these statistics are informative and make it possible to point the finger of products to see manufacturers who are hoping that they will improve things in the future. On the last page, we also publish statistics on sales in the first half of 2017, although with a less significant decline, but which already allows us to see the bad students.
For each product family we publish data by manufacturer, as well as parts with return rates greater than 5% or failing that the 5 parts with the highest rate. It is impossible for us to publish the rates of all the products, but if not we publish those of the parts having some common characteristics headlights (capacity for a hard disk, GPU for a graphics card, etc ...) See what good students are.
The statistics by brand are based on a minimum sample of 500 pieces sold, those by models on a minimum sample of 100 pieces sold. When the sample is smaller than 200 pieces, the designation is italicized. The largest volumes of tens of thousands of parts per brand and thousands of parts per model. Each time we compared the rates obtained by the manufacturers with those of our previous article on the subject published in December 2016.

does anyone tried SSD RAID 0 using USB 3.0 hub? i got mini raid enclosure just to test out to RAID my unused SSDs
apparently the max speed it can go not more than 600MBps....
that's the theoretical max bandwidth limit of usb 3.0. in real world, you cannot go that fast because of various reasons.
