The Transcend Ultimate 600X 64GB SDXC Card deliver UHS-I performance and up to 90MB/s read speed. No specific figure is quoted for write speed, but the card offers Class 10 and UHS U1 performance to guarantee at least 10MB/s write speed. The Ultiate 600x is avaialble in 8, 16, 32, 64 and 128 GB capacities. The card reviewed here is the 64GB SDXC version (TS64GSDXC10U1). A 32GB Ultimate 600x card was tested previously.
The Ultimate 600X SD cards feature Multi-Level Cell (MLC) NAND flash memory. MLC store bits per cell and has better performance than the less-expensive Triple Level Cell (TLC) variety. MLC uses more silicon per bit of storage but yields better performance durability.
Transcend prominently advertises the 600x Ultimate card at 90MB/s transfer speed. This is the read speed and does not carry over to write performance. To determine how a card will affect camera performance, write speed is the most important metric to consider. The 64GB card was benchmarked for read and write speed in several USB 3.0 card readers. In these test, the highest read speed of 96.8 MB/s surpassed its rating, while is the write speed measured up to 67.7 MB/s write speed. This is very respectable performance for a card that does not actually quote a write speed. Transcend does quote write speeds for its more expensive U3 cards, in fact this 64GB 600x Ultimate card surpasses the advertised write speed of the Transcend 95/60 U3 64GB card. It is much faster than the 32GB Transcend 600x card that peaked at 39.5MB/s write speed.
