Gives the Raptor 10,000 Rpm drive a run for its money, beats it in
most areas but a a few :)


And no kitty in it as yet :)

Fantastic. HDtach v3.0 measured my Raptor (WD740GD), and reported:

- Random access = 8.0 mSec
- CPU utilization = 3%
- Average read speed = 64.7 MB/s
- Burst read speed = 120.1 MB/s

Eyeballing the HDtach read speed graph, that Raptor shows a max. read
speed of ~72 MB/s on inner cylinders and ~53 MB/s on outer cylinders.

Note that HDtach's access time is the sum of seek time plus rotational
latency; in fact, it includes a (one sector?) read.

So, what did HDtach report for your 160 GB Hitachi?
 
Please, don't feed the little troll.

You'd better read that again.

Oh good, that is why they call it "access time" then and not "seektime".
in fact, it includes a (one sector?) read.

"in fact" and a question mark in the same statement, huh?

And whether it does or doesn't, doesn't matter, as the time to read
1 sector is less than .01 ms, totally swamped by seek and latency.

Worse on all counts.

Give it 2 months. If it's like my experience with anything IBM/Hitachi,
you'll be requesting an RMA very soon. It will either develop a bearing
whine, have problems finding sectors, or start chattering followed by a
spindown. You bought a bad brand of mass storage.

Uh, dunno about that. I have three Hitachi 72 GB SCSI DK 32 drives,
all bought used from EBay. All of them are fine, and run very quiet.

[troll-spotter bait: I use 80 -> 68 pin adapters, with nary a
problem.]

Sigh.
Obviously, it is ~72 MB/s on outer cylinders and ~53 MB/s on inner cylinders.

Yes, but then they are original HITACHIs, aren't they.
[troll-spotter bait:

Thanks for admitting that you are.

Where does it save the results, it wont let me cut and paste stuff on
the main screen :(


Though it has an average read of 47.8 and a burst rate of 116 :)


So iam happy with that my old segate had a average read of 33 or
somthing and a burtst of 60 at best i think.


AND I AM NO ****ING TROLL :p
