Lexar 1000x microSDHC: Good but not Great. Actually pretty decent.
Read performance is great -- using the included USB reader I was able to get 140MB/s read. Write speed on the other hand is disappointing, again using the included USB card reader, I was only getting 40MB/s.Update: retested this on a PC running Windows 10. Previous test was done on an iMac and I mistakenly made the assumption that the test result on iMac would be comparable to test results posted by others using CrystalDiskMark. A sequential write speed of around 60MB/s was obtained on a PC, making it a significant improvement of write speed over the blue colored 633x card. I am updating the score to 5 stars.Realizing that the benchmark results posted by other folks are not necessarily directly comparable to mine I set out to create a comprehensive list of current microSD cards on the market.
