Should you buy the biggest-capacity memory card you can afford, or several smaller cards? Over at slashdot, SuperBanana writes:
"Most pros don't use anything over 1GB. Why? Because 1GB is almost 120 photos for a [Canon 10D in RAW mode].... By using four 1GB cards, if one gets erased, stepped on, lost, or dies on you, you're only out 1/4 of your photos, instead of ALL of them.
"Furthermore, one can be in your 'digital wallet' widget on the laptop, while the other is in your camera. Oh, and it's hideously expensive for a 4GB card versus a 1GB card or a bunch of 512s..."
Do You Need 4GB?
* You don't -- if you just take photographs. That's enough storage space for about 10,000 image files, taken at Normal JPG resolution on the Canon PowerShot S1iS.
* You do -- if you also take movies. Four gigabytes is sufficient storage space for a half-hour of digital video, taken at the S1's highest quality and resolution setting.
BTW, 1GB CompactFlash memory cards have now fallen below US$100, as listed at J&R's Web site. By comparison, the 4GB card is 40% more expensive than four 1GB cards.
