Transcend, which makes flash memory cards for budget-minded buyers, announced on Wednesday two new high-speed CompactFlash models with transfer speeds up to 90MBps.
The Transcend Ultimate 600X cards are at the top of the line, able to read and write data at 90MBps by using the UDMA (Ultra Direct Memory Access) mode 6 interface. This line tops out at 32GB.
The Transcend Premium 400X cards range from 16GB to 64GB capacity and can write data at 60MBps and read data at 90MBps, the company said. The 400X and 600X cards use "premium" flash memory chips and employ error correction code (ECC) to nip some data transfer errors in the bud.
The company didn't announce prices, but high-speed models generally sell for a big premium over middle-range options. B&H Photo is selling the new Transcend 400X cards for $89 for 16GB, $205 for 32GB, and $369 for 64GB. The 600X cards are selling for $107 for 8GB, $200 for 16GB, and $300 for 32GB.
CompactFlash cards are common on higher-end SLR cameras, but the technology standard faces a challenge from the smaller SD format, which has just begun its transition from the SDHC generation to the faster, higher-capacity SDXC generation.
Lower-end SLRs from Canon and Nikon, the single-lens reflex camera market leaders, use SDHC. Canon's latest model, Rebel T2i, uses SDXC.
Transcend competes most directly with SanDisk and Micron subsidiary Lexar. It offers lifetime warranties on its CompactFlash cards.
