Toshiba BG3 M.2 SSD 256GB

I bought this rather odd shaped SSD drive from eBay. I was expecting to use this SSD drive on my laptop as a secondary drive. Not so surprisingly, it did not work as expected. I wrote a post on this issue and you are welcome to read it to better understand what went wrong. The bottom line was, I wanted to use this drive on the M.2 slot dedicated for WWAN slot.

Traditional laptop based SSD drives are either 2280mm or 2230mm in size. These sizes are very common in the market and are widely available. However, there are some laptops that supports 2242mm size SSD drive as well. Let's take a look at the specs of this drive first.

I performed the WinSAT test on this drive from my desktop computer. During the test stage, this drive was directly attached on the motherboard on an M.2 PCIe 3.0 slot instead and I did not use any type of adapter. So, I expect the result should be as authentic as possible while making sure there are no bottleneck.
