32GB Lexar SDHC Professional Class 10 Memory Card (LSD32GCRBNA133) $25 + Free Shipping (expired)

how does it compare to the sandisk in performance?

The Professional 133x at 32 GB reaches 23 MB/s sequential read throughput, according to h2benchw and CrystalDiskMark 3.0. It is comparably weak as Kingston's Ultimate XX lineup in 512 KB random writes at only 0.8 MB/s, although this type of workload is unusual for SD memory cards. Sequential write speeds never drop below 14.1 MB/s, which is still a commendable result, despite the fact that the UHS-I cards from Kingston and SanDisk reach almost twice the peak write throughput. The card is not very convincing if you hammer I/O-intensive workloads through it, and it does not deliver very high throughput in combined reads and writes.
