    "I used it on my ROG Z13 Flow, I basically cloned my disk and it just worked like a charm....If you need a large-capacity 2230 disk for your Ally or a similar device, this is one of the few options on the market currently that will satisfy that need, but it’s hard to swallow such a high MSRP even for this form factor.

Moving from a hard drive, I really felt the difference in loading speed. "
