/ Specifications Source Calculation Extra comments
Density (GBit/cm2) 18.4 datasheet 119(Gbit/inch^2)/(2.54^2) This is density on the storage platter, the density of the total (plastic) card is 8GBx8/2.54^2.54 = 10Gb/cm^2


Capacity (GByte) 8 datasheet / shop - Biggest size available for consumers
Price per unit (Eur) 72 shop (UK) - This UK website can deliver for about 30 euros to the Netherlands. The 8GB version is hard to find in the netherlands, the 4GB version costs 90 euros
Price per bit(Eur/GByte) 9 - 72 (price per unit)/ 8 (capacity) -


Data rate (Mbit/s) 40.8 up to 80 datasheet 5.1 MBx8 up to 10MB x 8 The (sustained) internal data rate is taken, depending on the track allignment (inner or outer) this is 5.1 MBx8 or 10MB x 8)


Access time (ms) 20.33 (average) datasheet / calculation 8.33+12 Access time = latency (8.33 ms) + seek time (12 ms) source:


Power consumption (W) 0.63 datasheet 190mA x 3.3V Average read/write current is 190mA. 190 x 3.3 (operating voltage) is 627 mW. Standby = 13mW, peak is 1023mW
