What's HD tune like? I just ran it on a 1TB Samsung I grabbed for £30 from a shop down the road - not a fantastic one, just new. It came annoyingly close to my best Raptor in parts - same ballpark at least, ~100M/s to ~130M/s, but the seek times were all over the place.

Still, seems like the gap has finally closed - be interesting to see how far they can go with the slower (than Raptor) spindle speed and where WD go next.

Nothing to compare it against really, but they utterly trounce all my 5 drive RAID 5 arrays (as expected really)

Looking forward for the W7 release, so I can piss around short stroking and using magic to make them really push raptors.

Can you actually tell the difference between your F3s and F1s in real world usage?

I'm thinking about getting one then sticking my F1 in an external caddy for backups.

I maybe have one F1, in a raid 5 array.

But compared to my old 150GB raptors, the F3s feel a little faster and make less noise.

As this was more a venture in getting more space, rather than a straigh upgrade, I'm very happy.

If I short stroke the drives, I'd expect the performance increase to be pretty noticeable.

Just because I've fettled my machine a bit (F3s on raid controller now)

Appears to be marginally faster than the onboard, but it's probably more to do with the W7 install than the drives.

No more latency though, which is what I was concerned about.

Edit: Item of note: Real world test shows Raid5 array copying to the Raid0, 210MB/s about 15 minutes for 160GB of files.

Nice. I now have two of these in a Raid 0 and another 3 in Raid 5 :)
