## Questions & Answers

**Q: Are these cards manufactured in China?**
A: Mine is stamped 'Made in Taiwan'

**Q: Will this card work as storage in a 2021 MacBook Pro?**
A: This is a camera memory card. Not sure if it is wise to use a card like this as a storage for your mac. Having said that, through a reader, this card technically can act as a storage for any laptop. I would never do it though.

**Q: What are the sustained read and write speeds of this card? are the read and write speeds of 300mb/s and 250mb/s only in bursts?**
A: My tests (using Blackmagic Disk Speed Test app) consistently got read and write speeds ~80% of the advertised max speeds, which is acceptable and good for SD cards.   So, sustained write speeds of ~200-220mb/s. and sustained read speeds of 240-250mb/s

**Q: Will this card work with olympus omd emi miii.?**
A: It will work with any device that uses SD cards.  However, unless you are shooting 4k, you may not need this card.  You could get away with a lower priced one.
