Larger Faster HDDs

Thread Starter 
From what I have read it is a major performance boost by getting a 7200 RPM HDD. Now the largest notebook 7200 RPM HDDis a 60 GB right? I saw a 100GB HDD in an HP (not 7200) does anyone know when an 80 or 100 GB 7200 HDD might be out?

Thanks
Ben

From what I know, the 100GB HDDs are 4200 rpm drives.... it is definetely a good sign for notebook hds.

why is it a good sign? 4200rpm sucks! Or do you just mean we've never seen a 100GB hard drive in a notebook before.

I think what they are saying is that it’s a good sign that there are larger hard drives coming out. I am sure the speed will go up sooner or later.

I dont want bigger harddrives but i am looking forward to the nice ones out now to drop in price.

Its a good sign that notebook drives are getting bigger. Now there is a 100GB notebook hdd... now we just wait till they bump it up to 5400 goodness, and finaly 7200.

A 100GB hd should be plenty fast despite only having 4200RPMs...due to the increased density of the drive. RPM isn't that good an indication of drive speed since there are so many other factors.

is seek time really important? how about cache?

I believe that seek time is how fast on average the hard drive can find information. If your hard drive was filled to capacity and you were to run a search for a file, the seek time is how long on average it would take to retrieve the file. Of course sometimes it can take much less or much more time to find. I'm not positive, but i think the cache is where information that you're most likely to access is stored for quicker retrieval. anyway, the bigger the cache,the better the performance of the hard drive. Most hard drives today have either a 2mb or 8mb cache.

Considering that I already have 2-60GB 5400s (could be upgraded to 7200s) (could have software Raid, but no hardware Raid in the 8887), and I could add 1-80GB 5400 to the TV Tuner bay on the 8887, with a total of 200GB internal storage, not counting readable CDs or DVDs or the SD card MP3 player, isn't the future now?

When I first got the 8887 with a single 60GB I quickly filled it, so I got a 2nd 60GB. Now they both stay only 50-65% full. If I got the 3rd 80GB internal then I could sell the blazing fast 250GB WD 7200 Firewire that I bought and only keep about 20% full. I mean, like, whatta ya' gonna put on it? All the music on the internet, every movie ever made that you don't watch that often anyway, or yer porn collection? I'm set for now. Next lappie will have hardware Raided twin 7200s, but I'm making it OK without them for now.

I have an 80GB HDD in my desktop now that is filled completely. I would like to have enough space without having to get an external HDD for my laptop. Will any 80GB or 100GB 7200RPM drive be out by the end of summer? Or does no one know except Mr. Hitachi?

Yes, I am looking for a laptop for college like many other people on the forum.

Thanks
Ben

The only thing that i found in regards to a date is this "http://news.designtechnica.com/article3454.html"

Where it says "Samples of the MK1031GAS will be available in May."

I wouldn't expect any 7200rpm hard drives to come out this summer. This is purely a guess but I would expect to see them maybe in November or December after the Sonoma platform is brought out for notebooks which will support serial ata.

This is incorrect. Rotational speed has a great deal to do with the speed of the HD. You might enjoy going to storagereview.com and reading up on HDs and the testing of them.

The fastest drives out there are always those with the highest rotational speed. No drive with a slower rotational speed has ever won a head to head with the same test conditions for both. There are, as you correctly point out, more factors then RPM, but this is very important.

Of course, RPM is still revelant. But it is not the only indicator of drive speed. Which means 7200RPM drives aren't exactly 1/3 faster than 5400RPM drives. I never stated that rotational speed has nothing to do with overall speed. I don't know why you stated "this is incorrect", as what you said afterwards only reaffirms what I stated.

You said rpms is not a good indicator of drive speed, this statement is incorrect. It is not the ONLY indicator, but for a single indicator it is the best.

You said a 100gb disk drive would be fast despite it's slow 4200rpm, this statement is incorrect.

I meant indicator as in it is not an absolute index. Sorry that I wasn't too clear. It is obviously a measurement of a drive's speed. However it only tells half the story. Only a combined measurement of spindle speed and areal density can be close enough to measure a drive's true performance. A high speed drive with low areal density may be slower than a low speed drive with high areal density. The only reason that currently spindle speed seems more important than areal density is because spindle speed varies more than areal density in current drives.

How can a statement like "100gb disk drive would be fast despite it's slow 4200rpm" ever be wrong? How do you define fast? I meant it would be faster than 4200RPM 40Gb drives. Nowhere did I imply that it would be faster than any 5400RPM drive.

It's a showdown between Bjorn and Deltawalkerl and I have front row seats. Oh boy!

Whenever I have to correct somone I try to give them an easy out.
You should have taken it, or at least thought things through.


What you said was false. Both in parts and in whole.

What you said:

So now you want to mealy mouth and claim you were saying it would be fast so long as I don't consider anything but other 4200rpm drives? While at the same time claiming a 4200rpm drive is fast and then saying drive rpm isn't that good an indication of drive speed?

Restated:
a drive with "X" should be fast because of Y and Z because "X" isn't that good an indicator of speed

What you said is quite clear. Its meaning is equally clear. The problem is that what you said is false.

You can not state something and claim to not have said it. You can not misquote yourself to claim you said something else.

Your statement was false. Live with it. Either learn more before you post or learn to take criticism better.

What is false? That two drive with equal spindle speed, the one with higher areal density will be faster than the one with lower areal density? Tell me that's false! If that is not the case, then there is nothing false in what I said. You either do not understand what I said or are deliberately twisting my words. Did I ever compare drives with different rotational speeds? Clearly not. Does RPM tell the whole story of drive speed? Also definitely not true. Like I said, only areal density and spindle speed together complete the measurement. Also as I stated, people may neglect areal density and not be far off in a comparison because this factor do not vary as much as rotational speed in today's mainstream drives.
