For your particular use case, I'm not sure my recommendation will do anything that your initial choice can't also do. It's just that your choice looks, well, a bit sucky and I can't tell if it switches between RAID modes using DIP switches or a button push. If the latter, then you need to be VERY careful because the out-of-the-box setting is RAID 0, and if there's any kind of glitch that resets that while you're using it for JBOD, you'll be unhappy.
By the time you've spent $75 on my recommended unit, you're already spending more than an external 1TB SSD would cost anyway, and pretty close to what a 2TB item costs.
So, I wouldn't touch your choice, but maybe you shouldn't touch my choice :-)
