Seagate Momentus 7200.4 thread

Before y'all rush out and buy the new 320 GB, 7200 RPM hard drives, you might be interested to know that Seagate has announced a new 500 GB, 7200 RPM hard drive, set to come out in Q4 2008.

http://www.seagate.com/ww/v/index.j...toid=19549a9dafc0b110VgnVCM100000f5ee0a0aRCRD

Unfortunately there doesn't appear to be any indication as to whether it will be the standard 9.5 mm size for 2.5-inch hard drives - some of the recently released 500 GB, 5400 RPM 2.5 inch hard drives were not - but with several months to go until release, there's hope that it will be.

In other news, Seagate also announced a forthcoming 5400 RPM, 500 GB notebook hard drive and a 1.5 TB, 7200 RPM desktop hard drive.

At any rate I think I'll wait awhile on upgrading my hard drive...the pace of notebook hard drive technology these days is amazing!

 

Why wouldn't they announce what size it would be? That's so stupid. They're just playing with our emotions

 

The pace is amazing, but the price gap gets wider between the 2.5" and 3.5" Lol, what am I complaining about. Those are two different technologies.

 

When they say that the drive size ranges from 250gb to 500gb, they mean that it will be available in a 250gb, and a 500gb model. Obviously the 500gb has 2 platters and the 250 has one. Their will probably be 300 and 400gb models too, which limit the heads on the drive to decrease capacity.

I hope seagate is not pulling our legs, usually when a harddrive is stated to be released, it is usually 6-8 weeks before one can buy them at an online store.

Considering its using PMR.... its gonna be the standard 9.5mm height which fits in all notebooks.

Its most likely available for shipping TO MANUFACTURERS. I don't mind sticking with the 7200.3 320GB, just because thats the highest configurable hard drive for my laptop model on Dell's site.

Hopefully by the time I fill it up there will be 750-1TB 2.5'' notebook drives available.

 

geez...I just got a 7200.3 320gb. Owell...by that time I'll most likely have transitioned to SSD I've always preferred faster performance over size. 128gb would be enough for me with an SSD which hopefully will be competitively priced by then compared with mechanical drives.

 

Ordered one (128 OCZ 22d) last week at overclockers.co.uk ..still waiting for it to arrive.

 

bump
no one knows when will be available ? need badly one of these

 

It does say Q4...

 

It's probably going to be hotter than other 7200 HD

 

Why ? I don't see any scientific reason

 

these sound perfect for the new dell M6400

 

You're right, there is no reason.

 

Some 7200 drives are cooler than 5400 drives...

 

I had all three generation of Hitachi 7200rpm drives in my system. Each series got progressively faster and more power efficient.
The 7K100 series uses 5.5watts, the 7K200 uses 4 watts, and my 7K320 also uses 4 watts.
After upgrading from the 7K100 to 7K200, a huge performance increase occured, and my harddisk temperature dropped about 15F.
Upgrading from 7K200 to 7K320 also gave a performance increase, but not as much as from generation 1 to generation 2. However, I bought the single platter third generation 7K320 and it runs cooler than the 7K200 did.

Hitachi is always much expensiver than Seagate in EU....So i think i will get 7200.4, not 7K500.

 

Hmm sounds interesting.. 250GB per platter - that's gonna be a huge performance boost over the 160GB per platter that they're using now!

I did some googling and all I could find at this point was this page:
http://www.span.com/catalog/product_info.php?manufacturers_id=56&products_id=22250&osCsid=33580fd

Would be cool if this came out in the next couple of weeks

 

yep, this drive seems to be very interesting, high density, high capacity, low power consumption but fast as hell, I hope
I often thought about a 7200RPM HDD, especially the Seagate 320GB, but now, after I read this I think I will get the 250GB one platter 7200.4 version.

PS: Is there a difference between a one platter and its two platter equivalent regarding speed, power consumption, noise and heat? Any benchmarks about such an comparison?

 

Generally speaking one platter versions make a bit less noise and have better power consumption. Access times tend to be a bit faster.

Differences are small though.

I don't have any benchmarks at hand. The drive charts at Tomshardware may be useful.

 

Thank you, I looked at the charts at Tomshardware, but sadly they contain only a few drives and mostly old ones. But it seems that you are right, they are at least not slower, so they can only be better

I think I know then what my next HDD will be, the Seagate 7200.4 250GB.

 

I was wondering the same thing, and I found this comparison between a single-platter WD 320GB desktop hard drive vs the double-platter 640GB, scroll down to the second chart:

http://www.anandtech.com/storage/showdoc.aspx?i=3269&p=2

So it seems like it does provide some benefit when it comes to heat (around 4 degrees C cooler)

And yes the 250GB option looks tempting for me too.. If I can see it online within a couple of weeks I would order it. I do want one soon though - my Lenovo X200 is on the way with a crappy 80GB 5400RPM so I don't wanna be stuck with that

 

I think the 640GB is a newer serie than the 320GB. So it's different than drives from the same series.

 

Yeah you're right the 320GB version was released earlier, but their model numbers are really similar so I think they're still part of the same series. Check out the table:


Interestingly (to me at least), the double-platter seems to have better access times and throughput rates, even though platter density is the same.

 

Well I've seen several people upload their HD Tune results to these forums and the one platter versions had faster acces times than the two platter versions. Transferrates on the two platters were slightly higher (afaik).

The drives I'm talking about are Hitachi 7k320 160GB and 320GB, and WD3200BEKT 160GB and 320GB.

 

Faruk, are those laptop harddrives?
Are we really going to have 640Gb and 750Gb laptop drives?

I think those are desktop harddrives, cause those WD numbers look like they are teh same as the ones on their desktop 640gb drives.

silly me, he said they were desktop drives a few posts up.

I was just curious cause this was a laptop drive discussion with desktop benchies.

K-TRON

 

K-TRON the point of Faruk was how single platters perform vs. two platters. Please share your experience too.

 

I posted an image of my 7K320 160gb drive with a single platter.
The drive was tested as a standalone drive in my desktop.

Here is my hdtune of a single platter 7k320 with nothing installed on it:


here is an hdtune someone here posted, a 320gb two platter model:


As you can see, their really is a difference in drive performance between single and two platter versions. The single platter drive should always have less seek time, because their is only one disc which needs to be written to, so the head doesnt have to be moving so much to access data

K-TRON

 

Good post. Most other 7k320 320GB have around 15.9ms Acces Time though.

 

I found a better benchmark, I was not able to find one with a 15.9ms seek, the closest I could find was a 16.2ms

how much should the 7200.4's cost when they're released?

 

Not sure but I would guess $200-220 at start.

WD5000BEVT is going for $185.

 

any news on a release date for this?

 

All I've seen is Q4 2008. No sign of it anywhere other than here so far.

 

Unfortunately I can't really wait for this cause I need an HD, so I ordered a 320GB 7200.3 last week

 

What sometimes happens is that they show up first as a configuration option at Dell. OEMs seem to get them earlier.

 

anything yet?

 

Thought people might be interested to know that I recently decided on getting a 7200.3 the pre-cursor to the 7200.4 and basically almost everywhere in Canada is sold out. I managed to wheedle out of someone that Seagate aren't moving any new ones till Nov 5th...it just be co-incidence but apparently if people don't have them in stock they won't be in again till then...

 

I think they are waiting only to get rid of the 7200.3 stocks. The new model was announced in July or August as far as I remember and they should already have the 7200.4 mass produced by now...

 

Yeah, the 7200.3 320 GB is going for $100 now...

 

Try $70-80

 

still not available yet?

 

This prices of the 7200.3 320 gb seem so tempting now. This 7200.4 better have some sort of noticeable difference in order to justify the price over the 7200.3.

 

I just purchased a 7200.3 because realistically I don't want to be sitting around with my 160GB 5200rpm hard-drive for when Fallout comes out tomorrow

There's no release date yet on the 7200.4 so I'm thinking if its still on target for a Q4 release it'll be late Nov/early Dec

 

I also just bought a 7200.3 320GB.
These things are very cheap now (< $90 before tax and shipping).

 

Any update on when the 7200.4 is available? I have a 7200.3 already and waiting for an update to the next one with larger capacity.

 

Is someone gonna ask this every day now?

If anyone knows something, I'm sure they'll post.

 

How much the price of 7200 500gb would be? If it is going to be >$200, I would just buy Fujitsu 7200 320GB now as Newegg has it for $90 free shipping. If it would be <150, I can wait until December.

And how would we know for sure if the drive uses 2 platters in a 9.5mm casing? If they are going to use 3 platters, then the speed wouldn't be any faster than the current 7200 320GB.

 

ah well I'm buying the 320GB now...

 

Take the lowest price of the WD5000BEVT and add 20%. That's what I expect at introduction.

The minimum capacity is 250GB. The max is 500.

 

According too Google, the lowest price for WD5000BEVT is $140. 20% of that is $28. Add them up and we have $168. With taxes we have about $182. Add shipping cost, we have about $190.

Hmmm, The Fujitsu HD would cost me $98 with taxes and free shipping. So, I would save about $90. I probably buy now unless there is a confirmation from Seagate that says the drive will be available in less than 2 weeks.

500GB per platter? Is it possible?
