What's the fastest USB 2.0 or SDHC card?

post #1 of 2
Thread Starter 
My car stereo (Parrot SMART Asteroid) can read MP3s off a USB 2.0 drive or SDHC card.

Which is faster?

I believe that USB 2.0 maxes out at 30 MB/s and I think SDHC is around the same time, right?

What about random access? (since they are both flash memory, which is the fastest [?], it should nearly SSD speed, right?)

My goal is to find the fastest method of storage because my car stereo also indexes all music from the drive so anytime I update the stick it needs to re-index, so I'm looking for the fastest available method...

Depends on how much you are willing to spend on your storage really. There's quite a difference between the low-tier and high-tier choices available.
If you have one of each the best way would be to store the same amount of music on both and see which is faster.
As for choosing what stick or what card you want, you'll have to read some reviews, of which there are a plethora on the great interwebs.

I'm not sure about the relevance of the random access in regards to your car stereo.
