Western Digital မွေန၍ ေနာက္ဆုံးေပၚ WD's 500 gigabytes-per-platter နည္းပညာအေပၚမွာ အေၿခခံထားတဲ႔ 7200rpm (Revolution per Minute) ႏွင့္ 2TB hard disk ေတြကုိထုတ္လုိက္ပါတယ္။ Desktop System ႏွင့္ အဆင့္ၿမင့္ Game ကစားၿခင္းအတြက္ WD Caviar Black နဲ႔ WD RE4 2TB တုိ႔ဟာ server နဲ႔ network storage ေတြအတြက္ ၿမန္ဆန္စြာအလုပ္လုပ္ႏုိင္ပါတယ္။ Drive ႏွစ္ခုလုံးက 7200 rpm လည္ပတ္ႏႈန္းနဲ႔ 64MB cache, dual stage actuator technology ၿဖစ္ကာ SATA 3 gigabits per second (Gb/s) ၿဖစ္ပါတယ္။ ဒီ Drive ႏွစ္ခုလုံးက Gaming / photo edition, multimedia and video လုပ္ငန္းေတြမွာ အထူးေကာင္းမြန္တဲ႔ performance ကုိေပးႏုိင္မွာၿဖစ္ပါတယ္ လုိ႔ WD's client storage systems ရဲ႕ Vice president & general manager ၿဖစ္သူ Jim Morris က ေၿပာၾကားခဲ့ပါတယ္။
၄င္းမွာ ပါ၀င္တဲ႔ အဓိက features ေတြကေတာ့
Dual processor – Twice the processing power to maximize performance.
Dual actuator technology – A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
IntelliSeek – Calculates optimum seek speeds to lower power consumption, noise, and vibration.
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.
NoTouch ramp load technology – The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
