I just switched from WD640AAKS x2 RAID 0 to WD6401AALS x2 RAID 0, and here are the results - AAKS vs AALS
System specs on which I ran HD Tach 3.0.4.0 long bench 32mb test un HD Tune 2.54 default test. I run all benches using the same exact OS image
MOBO: Asus P5K-E WIFI-AP (v.1006 bios)
CPU: C2D E8200 (Q744A860) @4,00ghz (1,353v vcore) cooled by TT BT
RAM: 2x1GB Crucial Ballistix DDR2 @1200Mhz (PC2-6400, D9GMH)
HDD: WD6400AAKS x 2 (RAID 0) / WD6401AALS x 2 (RAID 0)
VGA: ASUS RADEON HD4870 (1GB) cooled by TRAD2
SOUND: Creative SOUND BLASTER X-Fi Xtreme Music
PSU: Zalman ZM850-HP
WD6400AAKS x 2 RAID 0 HD Tune 2.54
VS
WD6401AALS x 2 RAID 0 HD Tune 2.54
WD6400AAKS x 2 RAID 0 HD Tach 3.0.4.0
VS
WD6401AALS x 2 RAID 0 HD Tach 3.0.4.0
GENERAL REMARKS:
Unrar(ing) large archives takes even less time. Boot time with AAKS after fresh OS install (using image created with acronis true image) was around 12,5 sec., with AALS boot time after fresh OS install (using the same image as previously) was @10,3sec. Boot time was measured with Bootvis - Trace - Next boot + drivers delays. I clearly noticed that with AALS the hdd starts spinning much earlier in the boot process than AAKS.
StableTrac - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations.
^^^^^^^^^^^^^^
Probably StableTrac is the reason why AALS is so god damn quite!!!
Furthermore I noticed that read speed stayed unaffected, eventhough I was installing stuff at the same time and copying data from external hdd. Not sure whether its due to the bigger cache or to the new invented dual processor technology..
