| 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 |
