Here are performance measurements for various memory cards. Remember that for digital cameras write performance is the most important because it can limit a camera's shooting speed. Read performance is important when a digital camera is in playback mode. The following measurements were all done using the same USB 2.0 multi-format card reader. The contents of the table below show that practical performance can be very different from advertised performance. Memory cards are often advertised with either a speed rating (4X,10X,40X, etc.) or a memory bandwidth (4MB/s, 8 MB/s, 12 MB/s etc.) rating yet read and write speeds are very different.
|Type||Card||Size||Write Speed||Read Speed|
|Accepts Secure Digital (SD) memory.||ATP MicroSD 80X||256 MB||3209 K/s||5693 K/s|
|Accepts Secure Digital (SD) memory.||Corsair 60X||512 MB||1776 K/s||6270 K/s|
|Accepts xD memory.||Fuji||16 MB||688 K/s||4270 K/s|
|Accepts xD memory.||Fuji Type M*This abysmal write-speed does not seem to affect the Fuji Finepix F10s speedy performance, but makes it very slow to download images and video. And yes, we triple-checked the performance!||1 GB||147 K/s||1957 K/s|
|Accepts Compact Flash Type I memory.||Fuji xD to CF Type 1 Adapter*Size depends on the xD card inserted into the adapter.||0 MB||564 K/s||822 K/s|
|Accepts Compact Flash memory.||Hitachi Microdrive*FAT32: The raw performance of the 6 GB microdrive is supposed to be higher but that is what we measured. We suspect that the FAT32 file system must cause some devices to operate extremely slowly. The 6 GB microdive operates that slowly in our benchmark system and our Konica-Minolta digital cameras. At this time, we are unable to confirm since this is the only FAT32 memory we have.||6 GB||177 K/s||1758 K/s|
