SATA Short Pins are for configurations where a SATA Long or SATA Punch connector is not going to fit. These are great for the tight spots you often end up with when modding. If your SSD or HDD ends up right up against something, these pins and the Connector that goes with them are the best option.
I have been building custom cables for many years and I have used all of the products that are on the market. These are the best pins I could source. They crimp cleanly and easily. They are difficult to bend and deform, they are a strong pin compared to many others. They are a great pin to work with, they save time and improve the quality of your cables.
