morgan, mad scientist We tested them using the SATA, FireWire 800, and USB 2.0 interfaces. SpeedTools QuickBench 4.01 was used. For "large sustained" test, we averaged the results for 5 runs with 60MB, 70MB, 80MB, 90MB, and 100MB block sizes (Extended Test). For the "small random" test, we averaged the results for 5 runs of 64K, 128K, 256K, 512K, and 1024K block sizes (Standard Test). Test "mule" was the 17" MacBook Pro 2.4GHz "Santa Rosa" with 4GB of RAM. LEGEND FOR GRAPHS INSIGHTS The WD Scorpio 5K drive was nipping at the heels of the Seagate Momentus 7K drive on large sustained transfers but fell back when doing small random transfers. The 200GB Hitachi 7K drive is the best compromise between speed and space.We must warn you that the newest, fastest drives use more battery power. We'll report on those specifics in a subsequent article -- but suffice to say, "You can't have it both ways." Notice how slow all three drives run when connected to the USB 2.0 port. If you are using these drives externally, the only interface that will run the drive off of bus power is FireWire (800 and 400). Both SATA and USB 2.0 require use of an A/C adapter on the notebook enclosure. Though we tested these drives externally, installing them internally will NOT make them go faster. This is based on our testing of the 160GB 7K drive and 250G 5K drive internally. NOTEBOOK ENCLOSURES SATA EXPRESSCARDS After we completed our testing, we received an ExpressCard/34 SATA host adatper from Trans International. We'll report in a future article if it differs in performance from the SeriTek. WHERE TO BUY 7200RPM NOTEBOOK DRIVES WHERE TO BUY NOTEBOOK ENCLOSURES Other World Computing has clear plastic enclosures (Mercury On-The-Go) with either FW800 + USB2 or eSATA + USB2 port configurations. WHERE TO BUY SATA EXPRESSCARD HOST ADAPTERS Check with Trans International about their new ExpressCard/34 SATA host adaper. WHERE TO BUY YOUR MACBOOK PRO "Santa Rosa" or other Apple products You can also purchase Apple systems and accessories from Small Dog Electronics. You can custom order from them just like with the Apple Store. PRE-ORDER LEOPARD WHERE TO BUY MEMORY FOR MAC LAPTOPS TransIntl.com is selling kits to take your "Rosa" MacBook Pro to 4GB. They also have kits to take your 13" MacBook to 3GB. Other World Computing sells various kits for the MacBook and MacBook Pro. They have done extensive testing with the 13" MacBook to see what gain is made from matching pairs -- including dual 2GB modules. Has Bare Feats helped you?
