In case anyone is curious:
G.Skill FF-TSDG32GN-C10 (current card on hand)
Seq Read = 92.96MB/s
Seq Write = 21.97MB/s
Rand Read 4KBQD1 = 5.25MB/s
Rand Write 4KBQD1 = 1.25MB/s
I went with the SanDisk Extreme 100MB/s V30 A1 (linked above) for $16 which should give me 99MB/s, 72MB/s, 9.6MB/s, 4.3MB/s respectively.
The G.Skill wasn't half bad, but $16 didn't seem too expensive to ensure I can extract the best performance out of whatever I end up doing with my Pi (kindof interested to see how far I can push the limits) by doing my best to reduce storage IO bottlenecks as best I can while still keeping the system portable. I figured I could either load up the G.Skill with a bunch of music and put it in my phone, or I could keep it for the aforementioned Magic Mirror project for my co-worker.
Everything should arrive tomorrow. Looking forward to this new frontier. This will be my first in-depth experience with Linux.
