I've uploaded some benchmark results on http://idlenoise.ifrance.com/benchmarks/
Test platform is an Asus A8N-SLi motherboard, X2 2.0 GHz (3800+) cpu overclocked at 2.6 GHz (~5000+); using nVidia nForce4 for IDE and SATA2 connections.
As you can see, the HD401LJ performs very well; slightly above SP2514N. This is a confirmation that HD300LD/LJ gets bad benchmark results (see online reviews) because it only uses 100 GB out of each 133 GB platter; a similar pattern as SP2004C vs SP2504C.
The temperatures you see on my HDtune screen captures are what I got after about 2 hours running all the benchmarks; both drives were put in Nexus Drive-a-Way enclosures. The case doesn't give any significant airflow around these enclosures, and it's a very hot summer day today in Brussels (32Â°C ambient when benchmarking), so these temps give us some indication about how cool these Samsung drives are when running disk-intensive tasks for a long time. Now I'm finished with the benchmarks, the SP2514N has stabilized at 43Â°C and the HD401LJ at 45Â°C; all temps reported by SMART feature.
AAM was disabled on both drives for running the benchmarks.
Enabling AAM in FTool provides about the same, unspectacular improvement in seek noises for both drives; anyway both idle & seek noise are very low on these drives.
I'll have to wait for a quieter environment (= a sleepless night
) to record idle and seek noises from both drives. I was surprised when plugging in the HD401LJ as it seemed easily as quiet or even a little quieter than any of my P120 series, both in idle and seek, while official Samsung dB/A values gives lower idle for the 2-platter. My SP2514N isn't having any noise problem (I've got 6 P120 drives actually, providing enough comparison points); so maybe I've been granted a cherry-picked HD401LJ, or maybe they're even better than what the specs suggest. My brand-new WD3200KS ? Beaten hands down...
