tbh, I think it's a nice but expensive solution.
Dunno if they are 100% Solid State drives (like the ones that are sold in eBay and local stores - 2.5" SSD drives of 4,8,16,32GB) but I think if you can afford them, they are a good investment.
I also dunno if they have CF limited read/write cycles like CF cards have. SSD IDE and SATA drives have a MTBF of 140 years so I think it's a nice way to invest that your precious Amiga Data will be there for a long time to come

Personally if I could afford it I would have gone to 2.5" 16 or 32GB SSD

Cheers
