jag kollade upp på hitachis site, och här är en jämförelse av funktionerna i dessa två hårddiskar:
---------
travelstar 80gn features:
Noise Reduction: Using a VCM Damper
Fluid Dynamic Bearing Spindle Motors
AFC "pixie dust" media
Giant magnetoresistive (GMR) head technology
Partial Response Maximum Likelihood (PRML)
Load / unload technology
Enhanced Adaptive Battery Life Extender (ABLE) 3.0
Adaptive Formatting
travelstar 40gn features:
Noise Reduction: Using a VCM Damper
Fluid Dynamic Bearing Spindle Motors
AFC "pixie dust" media
Giant magnetoresistive (GMR) head technology
Partial Response Maximum Likelihood (PRML)
Load / unload technology
Enhanced Adaptive Battery Life Extender (ABLE) 3.0
skillnaden är alltså att 80gn har "Adaptive Formatting" då tydligen, och den beskriver Hitachi så här:
"Hitachi has implemented a new technology called Adaptive Formatting in our HDD manufacturing
process.
The Adaptive Formatting technology is utilized to provide customers with HDDs that have
greater reliability through enhanced optimization of head performance.
Each drive is individually tuned at the factory to match the heads and media used in that specific HDD.
The media recording surface is formatted with an optimized Bits Per Inch / Tracks Per Inch (BPI/TPI) combination,
depending on the performance characteristics of the head associated with that surface.
The result is an increase of reliability and performance for specific head and media combinations.
This procedure eliminates the possibility of marginal heads that can occur in a drive using fixed BPI/TPI formatting."
om det är värt prisskillnaden vet jag dock inte, men ny teknologi är ju alltid trevligt
