not really as the main actuators swing the arm into rough position and then a piezoelectric on the tip(ish) near the head precisely moves it to the right track. Dual proc allow it to issue a command and receive the next one and calculate it all at the same time.

This is a SATA Drive and I look forward to it.

don't mistake me I look for it too..., my Cheetah are older , they are SCii

I was just asking if it's the same size, because we talk about the limitation of the plater vs rpm

It's actually 1308in/sec for the 2.5" drive and 1319in/sec for the 3.5". RPM is revolutions per minute, so you have to divide by 60 to get the speed in terms of seconds.

With the Caviar Black 2TB, there's really no reason to get that. Like, at all.

I wouldn't count out the VRaptor line yet. Never know what tricks they have up their sleeve. Just look at the 2TB vs 1TB. HUGE gains in random access. IF they do like I think they will (and I have no idea/ insider info, this all just a guess) we could see the next gen VRaptor out right destroy the "old" Vraptor. VERY interesting and might just be perfect for peeps not ready to take the SSD plunge yet want extreme speed at a fairly reasonable price (about 42 cents US a GB IF rumors on price are correct).

Sure there is, its the same reason the Raptors sold so well when they first came out. The capacity might not have been great but the speed was amazing and reliability was very good.

And if given a 64MB Cache they will absolutly dance all over a Black 2TB for speed comparision. Even if it doesnt' have the 2TB storage, I can promise you that people will be buying these for OS Drives.

If the power consumption numbers for the new VRaptor are anything like the old one, it should also beat the 2 TB Caviar black in performance / watt.
If it's not audible from 4 metres away like the old Raptors in my work, then I'd pick one up to replace my OS drive (currently using 60 GB of a Samsung 1 TB drive).

This new 600GB VRaptor might be interesting especially if they keep it in the $200 range. It's true that a single SSD drive will be faster but let's not forget that the price per GB with SSDs is still tremendously un-competitive even against a VRaptor.

In the past, I've always bought VRaptors - I am sure WD will once again find a market niche for this drive. They're not stupid - someone has obviously done the math and concluded that despite the SSD revolution, there will be enough buyers of the 600GB VRaptor to at least cover the R&D and production.
