Hitachi 7K320 - When can we actually get one?

RaceTripper said:
Making any kind of judgment on a drive by comparing any external USB2 drive to an internal SATA 1.5 drive makes no sense. The only valid comparison is internal SATA vs. internal SATA or external USB2 vs. external USB2.

In that case, then I guess numbers are good: it's ~40% faster than the stock internal SATA drive.

. . . not AFAIK much of an improvement over the 200GB Hitachi 7200 BTO option:

How do I read these benchmark tests? I'm interested in comparing the M6 and the 7K320; mostly interested in the M6 unless the speeds are WAY far down from the other. At any rate, what I've got now will pale besides either one, I suspect (Hitachi 5k120).
 
this vibration issue could prove quite important; if hitachi has rushed to get their 7,200rpm 320 gigger out to offer competittion to the WD Scorpio, then perhaps there was a little oversight on this issue. I hope not, I hope that it's a one off, or a small batch issue... otherwise i might get the scorpio as on the (very few) benchmarks i've seen, the two drives look similar thus far...

anybody else got any benchmarks of these drives yet? real-world are prefferable but synthetic is better than nowt!

1) seagate 7200.3
2) wd scorpio 320gb (7,200rpm)
3) hitachi 7k320
4) samsung M6 500gb (5,400rpm)
 
Over on Notebookreviews we've gathered some results and sofar it looks like this:

HD Tune, acces time, average transfer rate
WD 3200BEKT, 15.9ms, 63.3 MB/s
ST 7200.3, 17.0ms, 69.5 MB/s *
HT 7K3200, 16.2ms, 63.1 MB/s

But HD Tune is just a synthetic benchmark so this doesn't give the whole picture.

We're trying to gather PC Mark Vantage results for these drives which has a bit more vailidity as a benchmark. Sofar we've only found the results for the WD.

HD Tune: http://forum.notebookreview.com/showthread.php?t=270564
Vantage: http://forum.notebookreview.com/showthread.php?t=271955

Based on these initial results I'd put my money on the WD for the winner. The acces time for the 7200.3 is just to slow it seems. But it is unsure how reliable the HDTune result was.

* These HD Tune results could be unreliable. A second HD Tune result for 7200.3 shows 15.9 access time.

Tomshardware has benched the 500GBs. One word: disappointing. Very slow access and a high of powerdrain.
 
Interesting stuff. Yeah I think there's probably a wealth of people who are holding out for more benchmarks - and perhaps some real world user reports -WRT the hitachi vibrating for example.
 
Actually I would take these HDTune results I posted with a grain of salt. A second HD Tune result for the Seagate 7200.3 shows 15.9 access time.

So it's too early to draw conclusions yet. But going by the HD Tune results Seagate seems to have the edge.

We've had two people on NBR complaining about vibration of the 7K320. Both were MBP users.
 
I'm down to about 13GB on my original 120GB so now I'm looking for a new HD. Hope more user reports and benchmarks come out soon since school starts in about 1.5 months!

Racetripper above said he noticed something but it went away after a few days, fwiw.

My drive has been fine. I don't notice any excessive noise, vibrations, or heat. Battery life is as good as with my original 5K160.

Yes. I've done it three times now. It's easy. Takes 15 min. ifixit.com has the tools and instructions you need.

Always thought it was extremely difficult to change it but a guide would definitely help. Did you need a grounding wrist strap?

The hard part is all the tiny screws (requires a Phillips #00 and Torx #6). Didn't use one, but it's probably not a bad idea.

OWC has competitive pricing and excellent customer service. They show shipping time for the 7K320 as "pending" however. Might need to contact them to ask when it will be available.

Ditto to what you said - I can often find hard drives and memory at prices slightly lower than OWC's, but I am extremely happy with their customer service and reliability. So I only use them for memory / notebook hard drives.

I went ahead and got the WD Scorpio Black, and the necessary tools from ifixit. Now I'm just looking for the nerve to go ahead with it. :D

Mostly, I'm still unsure about the cloning and whether I need to format (?) the drive before anything (not partitioning at this time). I've got an enclosure for the WD (and I've also got everything backed up via Time Machine (better to do this transfer that way or carbon copy clone?). Anyway, I'll have to dig through all the bookmarked threads I've collected over the past couple of months.
