Rundel Datentechnik: Memory Cards

Quick Tip: Memory cards

Flash cards are available in capacities of over 400 MByte. They don’t need any power to maintain their memory.

Compact Flash cards use the same technology as Flash cards in a smaller package. These cards work in the second card slot of the HP 320/360/620/690LX/Jornada 710/720/728, and other devices with Compact Flash slot, and they can be used just like a standard Flash card with the help of the CompactFlash adapter.

SRAM cards need a backup battery to maintain their contents. Write operations are a little bit faster than on flash cards, while read operations are almost equal on both card types.

SecureDigital (SD) and MultiMedia (MMC) cards are newer technologies which are much smaller and thinner, but are not yet used by many devices.

SanDisk Flash Memory Cards

PCMCIA 2.0 Type II cards for additional disk storage. The cards work in all HP Palmtop PCs (except the 95LX), HP OmniBooks and most other computers with a PCMCIA 2.0 Type II slot and card and socket services.

Memory cards with a capacity of more than 220 MB don’t work in the HP 200LX without special driver software.

Please note that we no longer offer PCMCIA cards with a capacity of less than 96MB. For such capacities, it is more economical to use one of the CompactFlash memory cards combined with a CompactFlash adapter.

Sandisk CompactFlash I (CF I) Memory Cards

These cards work in most devices. An PCMCIA adapter card is available which allows CF I cards to be used in any device with a regular PCMCIA card slot, for example almost all notebooks.

Sandisk CompactFlash II (CF II) Memory Cards

CompactFlash II cards have higher capacities than CF I cards, and they are a bit thicker. Both types of cards work in the Sharp Zaurus.

IBM Microdrive

The IBM Microdrives have been tested to work in the HP Jornadas and the Sharp Zaurus, but power consumption is quite high. We would not recommend to leave a Microdrive in the card slot for extended periods of time.

Sandisk SecureDigital Memory Cards

The SD cards have the size of a small stamp and come in various capacities.

The Sharp Zaurus supports a CompactFlash (CF) card in its top slot and a Secure Device (SD) card in the left slot. Both cards can be inserted at the same time. If you plan to use a modem, network or camera card in the CompactFlash slot, you should plan on getting a SD memory card instead of a CF card for storage.

And other Manufacturers?

We found out that the Sandisk cards are one of the best brands available. They work in cameras, handhelds, PDAs, computers, without any problem, and we have yet to find a device where a Sandisk card wouldn't work. That's the reason why we strongly recommend Sandisk (and don't sell anything else). Sandisk cards may be a bit more expensive than other brands, but we are sure that it pays in the long run.
