My Current Favorite 2.5” Drive + Enclosure

Drive:

• Seagate Momentus 7200.4 G (Model#: ST9500420ASG; note: ‘G’ = Shock Protection, there’s a ST9500420AS, sans “G” as well)
• $120 @ ProVantage
• 500GB !
• 7200RPM
• 16MB Buffer
• 3.0GB/s SATA-II

Enclosure:

• CoolMax HD-250L-eSATA
• TigerDirect = $25
• It’s leather so it hides greasy fingerprints very nicely compared to other hard shells
• The cables are a bit long & bulky compared to the nice little ones that come with say the WD Passport… but the outer case has a nice little pocket that keeps them in check.

 

Previous Fave':

• Western Digital Scorpio “Black” with Free Fall Sensor (Model#: WD3200BJKT)
• ~$80 street
• 320GB
• 7200 RPM
• 16MB Buffer  
• the so called ‘Black’ series = 7200 RPM
• ‘Blue’ series = 5400
• 320GB is currently WD’s largest capacity
• Only models with the "J" in the model have the "Free Fall Sensor"
