Lexar 300x Professional UDMA CompactFlash Card

Lexar's new CompactFlash cards offer minimum sustained write speeds of 45MB/sec

When it comes to memory cards used in high-end D-SLR cameras, speed is king. SanDisk and Lexar typically battle it out for the speed crown in the professional sector, but today Lexar has just kicked things up a notch.

The previous speed king was SanDisk's Extreme IV CompactFlash series which offer up to 40MB/sec sequential read and write speeds thanks to Enhanced Super-Parallel Processing or “ESP.” Lexar has now struck back with its 300x Professional UDMA CompactFlash cards which offer minimum sustained write speeds of 45MB/sec. According to Lexar, the new cards offer a 125% performance increase over its previous 133x Professional CompactFlash offerings.

"Our new Professional UDMA 300x speed-rated cards dramatically improve the photographer's workflow by reducing the time needed to download images after a shoot. Working in conjunction with one of our new UDMA-enabled CompactFlash card readers, a photographer instantly benefits by having more time to capture, manage, and share his or her images," said John Omvik, Director of Professional Product Marketing for Lexar.

The 300x Professional UDMA CompactFlash Cards will be available in capacities of 2GB, 4GB and 8GB starting in April. At that time, Lexar will also introduce a new Professional UDMA FireWire 800 Reader ($79.99) and Professional Dual-Slot USB Reader ($49.99) to take full advantage of the Professional UDMA 300x CompactFlash cards.

Oy vey....

ReadyBoost works in conjunction with SuperFetch.

SuperFetch is designed to cache programs (and whatever else) in memory before they're needed, thus compensating for the fact that, as you said, RAM is volatile.

ReadyBoost simply gives Vista another place to stash that cached data. Since flash memory has such low access times, reading data off of a flash drive can be better than reading it off the Hard Drive.

So, while it is true that RAM has nothing to do with how ReadyBoost works, obviously it's much faster for SuperFetch to cache to your system memory and only then to the flash drive, so having more RAM in your system dramatically reduces the need for ReadyBoost.

More RAM will always have far more effect on your system's performance than ReadyBoost could hope to attain. The only reason that ReadyBoost makes sense is that most people already have a flash drive kicking around.
If you're going to actually spend money, though, it's far better to put your money into more RAM. Even if you can't get as much RAM as you could flash memory for the same price, the sheer speed differential more than makes up for it.

The only reason Readyboost makes sense is that MS thinks people are too stupid to upgrade their system memory, plugging in a USB memory drive is a stop-gap measure for the typical budget PCs that sell in highest volumes - but with less memory to meet those low price points.
