Panasonic Memory Cards
Cards are the industry standard for today's removable flash media-based products
like digital still cameras, camcorders with still photo modes, digital music
players, and more. High mega pixel digital still cameras and video recording
modes require faster recording times for your media. Panasonic SD cards record
up to 10MB/s, faster than the majority of standard SD cards available.
Panasonic Introduces New 8GB* and 16GB High-Speed SDHC UHS-I Memory Cards
Panasonic RP-SDY16G Memory Card
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.

There are different speeds of SD card available. The official unit of measurement is the Speed Class Rating; an older unit of measurement is the × rating.
Speed Class Rating
The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. It is equal to 8 Mbit/s, and it measures the minimum write speeds based on "the best fragmented state where no memory unit is occupied
The following are the ratings of some currently available cards:
Even though the class ratings are defined by a governing body, like × speed ratings, class speed ratings are quoted by the manufacturers but unverified by any independent evaluation process.
- Class 2: 16 Mbit/s (2 MB/s)
- Class 4: 32 Mbit/s (4 MB/s)
- Class 6: 48 Mbit/s (6 MB/s)
- Class 10: 80 Mbit/s (10 MB/s)
Important differences between the Speed Class and the traditional CD-ROM drive speed measurement ("×" speed ratings) are:
On 21 May 2009, Panasonic announced new class 10 SDHC cards, claiming that this new class is "part of SD Card Specification Ver.3.0". Toshiba also announced cards based on the new 3.0 spec As of December 2009, the SD Association's Web site does not include information on this new class or new specification.
- 1. the ability of the host device to query the SD card for the speed class and determine the best location to store data that meets the performance required
- 2. class speed defines the minimum transfer speed.
Since the class rating is readable by devices, they can issue a warning to the user if the inserted card's reported rating falls below the application's minimum requirement.
The × rating is a unit of measurement equal to 1.2 Mbit/s. It is derived from the standard CD-ROM drive speed of 1.2 Mbit/s. Basic cards transfer data up to six times (6×) the data rate of the standard CD-ROM speed (7.2 Mbit/s vs 1.2 Mbit/s). The 2.0 specification defines speeds up to 200×, but unlike the class rating system, does not mandate that x-ratings measure the card's sustained write-speed. For most cards, the maximum read speed is typical faster than its maximum write speed, leading some manufacturers to use read-speed as the ×-rating measurement. Other vendors, such as (Kingston, use write-speed.[
