I bought 3 to carry 3 of my T5 SSDs with me every day. They have decent stiffness but are soft inside and out so they won't scratch SSDs or other items in your backpack. My only complaint is that the T5 SSD cables have velcro for cable management and will get stuck in your pocket. The best solution would probably be to just have a cover so the cables don't touch the hard drive.
