Yes, they are related to speed: IV is usually faster than III, III than II. (THere is no "I," as far as I know.) They're even more strongly correlated with price. For example, using B&H's basic prices, without counting rebates:
- 4 GB Ultra II: $24.95
- 4 GB Extreme III: $33.95
- 4 GB Extreme IV: $64.95
There is a rebate program in effect now (seems to be one much of the time), so the net prices (not counting shipping) for one card would be $19.95, $23.95, and $44.95. The rebates are higher per card if you buy more than one. If you bought three identical cards, the Ultra II would be $14.95 each, the Extreme III $13.95, the Extreme IV $34.95. At that price, it would be silly to get the Ultra II cards.
Be careful, though. Whomever managed an earlier series of SanDisk rebates on SDHC cards refused my application, saying that it was past the end date. They went by date the receipt was emailed, not the date I actually bought the cards, which was shown on the email invoice. When I inquired, they didn't even answer. It cost me $60. On the other hand, last October, I got three 8 GB Extreme III CF cards for a net cost of $12.20 [] from Adorama. The cards were $56.95 each. By getting three, I received a $160 rebate. The "bad" part was that it was in the form of a Visa gift card. I couldn't use that plus another form of payment for an online order, but I was able to put together an order for $158.65. (I may have been able to use two forms of payment by making a phone order, but the "loss" was only $1.35--figured into the net cost above.)
