Sony DSLR A-900 Write Speed (Firmware Version 1.00)
This page was last updated on October 9, 2008

The data in the table below was derived by timing how long it took the Sony DSLR A-900 to write 20 Extra Fine JPEG and then 10 uncompressed RAW .ARW photos to the memory card. Timing commenced when the camera's card status light illuminated, and stopped when the light went out. Each test cycle was performed 3 times (if the card's capacity allowed for that) to ensure accurate results.

Prior to both JPEG and RAW testing, all CompactFlash cards were first secure erased on a computer, then formatted in the camera. The same test scene was photographed, under the same illumination, for all tests. The identical camera settings and lens were also used for all tests. (This camera has a second slot, for a Memory Stick Duo-series card, but we did not test this media type.)

Interpreting the results The data can be sorted by manufacturer, card type, rated capacity and file format, in both ascending and descending order, by clicking on the appropriate column header. When sorting by JPEG or RAW, the fastest 10% for that format are highlighted in blue. You can view extra information for a card by clicking the icon to the left of the card's name, or for all cards at once by clicking Show Extra Info in the Memory Card header field. Note that MB/sec refers to megabytes per second, and that all calculations are based on 1 megabyte = 1,048,576 bytes.
