Panasonic to ship 8GB and 16GB SHDC with promised 60MB/s read speeds  
Thursday, September 2, 2010 | by Rob Galbraith
Panasonic has announced 8GB and 16GB SDHC cards that are promised to deliver 60MB/s read speeds (no specific write speed data has been given).

The new memory cards utilize the faster UHS-I bus interface in achieving quicker throughput. As of this writing, no shipping or announced Canon or Nikon digital SLR supports UHS-I. This means Panasonic's new cards will operate within a bus interface maximum of 25MB/s in today's SD slot-equipped cameras from each manufacturer.

Digital SLRs with SD slots that can take advantage of UHS-I should become commonplace in 2011. We're unaware if any card readers that support UHS-I, though it's mostly a moot point right now. Almost all SD readers available today are USB 2.0 (including ExpressCard SD readers), and are not capable of throughput anywhere close to 60MB/s.

So, Panasonic's RP-SDY08G 8GB and RP-SDY16G 16GB SDHC cards may hit store shelves before there are very many cameras and other devices that can take advantage of their claimed speed.

More information is in the press release below.

Panasonic Introduces New 8GB and 16GB High-Speed SDHC UHS-I Memory Cards

Berlin, Germany (September 1, 2010) – Panasonic announced today its newest 8GB[1] and 16GB SDHC UHS-I Memory Cards – the RP-SDY08G and RP-SDY16G. UHS-I is the new standard for higher-speed Bus interface defined by the SD Association as part of the SD Memory Card Specification Ver.3.01, which provides up to 104MB/s performance. Both memory cards have maximum data transfer speed of up to 60MB/s[2] and Class10 speed specification.

With the higher reading speed of up to 60MB/s, the 8GB and 16GB Memory Cards can transfer data to a PC more than two times faster than Panasonic’s current Memory Cards.[3] These also offer stable writing performance with Class 10 speed specification, ensuring highly-reliable 3D and full HD video recording.

Like the current Gold model memory cards from Panasonic, the RP-SDY08G and RP-SDY16G both incorporate Super Intelligent Controller (SICS), which is designed for high-level data protection. The Power Failure Protection function automatically retrieves data when power suddenly fails and preserves important data. This high power failure protection is certified by TÜV Rheinland, by passing their power on-off test[4]. More than ten times longer archival life has been achieved by the Refresh function. The Super Intelligent Controller automatically cleans up accumulated errors, extending card life.

Also, Smart Data Writing equalizes the rewrite frequency on each writing area of the card to prevent rewriting in a specific area, thereby minimizing the defect risk of the card.

Both the RP-SDY08G and RP-SDY16G Memory Card models will be available from November, 2010.

1 1 GB = 1,073,741,824 bytes. Usable capacity will be less.
2 Under UHS-I bus interface(SDR104 speed mode).
3 Theoretical figure. Actual speed depends on devices and conditions.
