250GB 5K Notebook Drive
The Two Fastest 7K Notebook Drives

We finally got our hands on a Western Digital Scorpio (WD2500BEVS) 250GB 5400rpm notebook drive (courtesy of Wiebetech). Many of you are wondering how it compares to the Seagate Momentus 7200.2 160GB 7200rpm notebook drive optional on the newest MacBook Pro and the new Hitachi Travelstar 7K200 200GB 7200rpm notebook drive. For power users, these are the three notebook drives of the greatest interest.

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.

200G 7K = Hitachi Travelstar 7K200 200GB 7200rpm SATA notebook drive
160G 7K = Seagate Momentus 7200.2 160GB 7200rpm SATA notebook drive
250G 5K = Western Digital Scorpio (WD2500BEVS) 250GB 5400rpm notebook drive

The Hitachi 7K200 is still the speediest notebook drive we've tested to date.

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.

Trans International provided us with their miniXpress825s and WiebeTech provided us with their ToughTech XE mini. Both notebook enclosures feature connectability to SATA, FireWire 800, FireWire 400, and USB 2.0. These Oxford Semiconductor 924 based units are the most versatile available currently.

For external SATA testing, we used the FirmTek SeriTek/2SM2-E ExpressCard/34 SATA host adapter.

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.

Check with Trans International and Other World Computing (OWC) for bare SATA notebook drives.

Trans International has the miniXpress825s and WiebeTech offers the ToughTech XE mini. These compact aluminum enclosures are the most versatile (FW800, FW400, SATA, USB2) and are therefore our favorites.

Other World Computing has clear plastic enclosures (Mercury On-The-Go) with either FW800 + USB2 or eSATA + USB2 port configurations.

Visit FirmTek's website for information on the
SeriTek/2SM2-E ExpressCard/34 SATA host adapter and other SATA adapters and enclosures for all the SATA host adapter options they offer.

Check with Trans International about their new ExpressCard/34 SATA host adaper.

We have tested the memory from the following third party companies in our MacBook Pro "Rosa" and MacBook. We can recommend them wholeheartedly: 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.
