I'd like mine XT!

 

9.5mm height?

 

Yes 9.5mm height. 2 375GB platters.

Model ST9750420AS SATA 3Gb/s 750 GB 16MB 7200

I haven't seen any (r)etailers offering it yet.

 

didn't samsung or toshiba offer 7200rpm 750GB drives before seagate?

 

Samsung announced a 640GB 7200 RPM a while back.

Seagate has the 750GB honor.

 

hmm 640gb did not stay top dog for very long.

Cant wait to see a nice smooth even 1TB number

 

If the XT has any success I would guess there will be a 750 GB XT fairly soon. Since it is also at a price premium already it would be nice to see 8GB nand there and internally raided chips to give 2x the speed output on the NAND section.

I think seagate is going to have something with the Hybrid drives. What is nice is since it gives SDD manufaturers a cost effective competitior it should bring those astronomically high prices down a bit. Even since the anouncement of the Hybrid dirve, and G3, it looks like SSD prices are taking a dive.

Even having 750GB available to a fast HDD makes the decision tougher between SDD and HDD. This larger disparity in storage size compared to SDD's should bring SDD prices down as well. So I welcome the anouncement and am very interested in how it bench's.........

 

Ummm, what do people actually use drives these large for on laptops anyways?

Or are these going to be included in desktop systems and other SFF units in the future? Seems to me that they'd make excellent drives for DVR's and other embedded consumer devices. And even home servers.

 

Consider games, AV files (i.e. HD movies), etc. I have over 300GB in just Steam games alone, not to mention a couple hundred GB of HD movies, and about the same for DVD quality movies. Not that I'd put all that on my laptop drive, but a lot of it I might.

I am surprised that this tech isn't reaching 3.5" as well. Let's see if WD throws a crazy amount of read and write cache (say 8GB each) in their velociraptor drives. Imagine 10k drives with the boost that this tech gives it. Crazy stuff.

 

It kind of gets on my nerves that I am stuck with 2TB drives in 3.5" form factor while they are able to cram 750GB in the 9.5mm 2.5" drives. For DVR's and stuff like that though 3.5" drives are fine though since they are just big boxes and you really want to maximize reliability and storage space while minimizing noise. The 2TB WD Green drives excel in this regard. When I first got my laptop I bought a 500GB internal drive for it but then realized it was a waste and just sold it and expanded my 3.5" drive collection. I guess if people want to carry lots of content around with them all the time these bigger laptop drives are great. I just want these manufacturers to throw us 3.5" drive users a bone soon with 3TB.

 

You have a point there. 3.5" drives have something like twice the surface area and twice the height to play with, so areal density is probably already good enough for 3TB drives.

If Seagate can do 2x375GB in a laptop drive, and WD can do 3x333GB (though in a 12.5mm height drive), 4x750GB should be possible, although I've heard that the first 3TB HDDs will be coming in a 5x640GB configuration.

As far as I know, the biggest issue with 3TB drives is addressing - the maximum that can be addressed with LBA with a 32-bit operating system is 2.2TB (or 2 TiB). Selling drives that will only work with 64-bit OS is presumably something manufacturers weren't in so much of a hurry to do, and so we've been stuck with 2TB drives for a year now.

3.75TB (5x750GB) drives would be nice to see...

 

I read on Ars Technica the other day that one of the big manufacturers (can't recall if it's Seagate, Hitachi, or WD) is coming out with a 3TB soon. And they will work with 32-bit operating systems, including XP, Vista, and Seven. There's a limit in the BIOS on the number of sectors that limits HDD's to 2TB with the standard block size, which OS'es such as XP assume will be present (IIRC, this is not the case with Vista or later). This can be worked around with some fancy HDD wizardry, though, with the result that XP won't get quite as fast of performance from drives above 2TB, but will still work correctly. The way I read it, the performance penalty sounds similar to what OS'es that don't support TRIM on SSDs get when running those drives (that is, any OS prior to Seven that's running a non-Intel SSD), but I haven't seen any actual benchmarks of what the impact is.

 

That's interesting. Do you have a link that describes this "fancy wizardry"?

The main limitation I've read about is addressing, and it makes sense - 32-bit addressing with 512 byte blocks means 2^32 * 512 = ~2.2 trillion bytes or 2.2TB. Also, further reading has revealed that this issue has nothing to do with LBA - the current standard for LBA is 48-bit addressing.

Additionally, it looks like there's another major issue in that the MBR standard only allows for 2.2TB to be used, because MBR uses 32-bit addressing. As such you need to use GPT for larger sizes, but this will generally mean you won't be able to use it as a boot drive unless you have an EFI motherboard or use Linux.

Further research suggests that, in fact, operating systems with support for GPT should be able to handle sizes larger than 2 TiB - in particular, this means that the issue is not so much 32-bit operating systems but 32-bit XP in particular, because it doesn't support GPT.

As games and huge AV files are on the table, don't forget some us with 450 gigs of lossless music files..the whole collection Do we need all the space? Nah..huge drives makes that horrible re-install noise depending how you have it backed up. I better get two to be safe?

Still dreaming of a 512GB SSD for $200..

 

dream on for 10 years lol..

 

Wonder if they will have a workaround with existing laptops to break the 2TB barrier.

 

I don't see the problem with 32 bit systems. You have a new 4T drive, you partition into, 2 each, 2t partitions or update to a 64bit system. Did I miss something?

 

The issue, I believe, is the way the MBR is set up - see here. Here's a quote:

As I said previously, the solution is to use GPT; it seems that this can still work fine on a 32-bit system unless you're using 32-bit XP. From the Wikipedia article:

However, with GPT you can't use the disk as a boot disk unless you have an EFI BIOS, use Linux, or can find some other kind of hack (Perhaps using a hybrid MBR/GPT setup where the MBR would only list the system partition, while the GPT would list both?).

 

3 to 4 weeks according to most websites. Price just above $100.

Seagate Momentus 7200.5 ST9750420AS SATA-300 2.5" 7200rpm (750GB) - SATA 2.5" 750gb

 

That's not a bad price at all. Can't wait to see benchmarks between the high-speed, high-capacity spinners.

 

Any news on it?

 

Span has changed the availability date. First it was available "within 28 days" now it says "within 11 days".

In stock in the Uk:

Seagate Momentus 7200.5 750GB 7200rpm 16MB Cache 2.5" SATA 3.0Gb/s Mobile Hard Drive

 

Wow! I'm am very curious to see how this drive performs.

 

agreed, in steam games alone I have 136GB or so. installing them on different drives is a major pain

 

Feel free to fund me and I will happily tell you

 

Tempting If they would have shipped to Holland I would have already ordered. But I'll just wait patiently for some to post the first results.

The big question is if Seagate can make the 750GB quicker than the 500GB. Sofar most larger than 500GB drives have been mediocre performers.

Edit: Lamba Tek expects stock 12th of August, it's a bit cheaper there.

Well you let me know and i'll help

I use a caddy in my optical drive anyway so benchmarks would be easy.

 

Sounds pretty sweet....would be a nice upgrade to my Seagate Momentus 7200.4 500 gig drive.

 

Did anyone get one yet?

If so please post some benchmark results like HDTune.

 

Coming close now. "available within 5 days"
span.com Seagate Momentus 7200.5 ST9750420AS SATA-300 2.5" 7200rpm (750GB)

Maybe but maybe not. Sofar the 750GB drives have been slower than their 500GB counterparts.

 

I want to see a 1tb on a single platter in a 2.5" 9.5mm drive, I can dream can`t I , ooh and i want it XT also.

 

Check this out!
TigerDirect @ $99!

Has anyone gotten this drive yet? If so, what is the good, the bad, and the ugly?

 

Do they have stock? I can't find it.

As far as I know the performance of this drive is a big mystery. No one has benchmarked it yet.

 

They had it in stock when I posted the link but it looks like it is on "pre-order" now. That's weird.

See if this link works better:

Maybe they had a couple in stock. Seems to have happened in the UK too.

 

I see... I hope the drive is awesome. I just bought the Hitachi 500gb 7200 Travelstar to see if I get a big bump in performance over my stock 500gb 5400 drive. I'd rather spring for more space too!

Have you noticed a big difference in performance between 5400 and 7200 drives?

 

It's a difference but not that big. Going from 7200rpm to SSD or Seagate Momentus XT feels like a bigger difference.

This review shows the performance of a 5400rpm drive, 7200rpm drives and SSDs in a notebook:
SSD vs Hard Drives: A Beginner's Guide to SSD Upgrades

 

See here for how big a difference you can expect.

See:
http://forum.notebookreview.com/har...ba-mk3252gsx-vs-hitachi-7k500-real-world.html


Even compared to the 'best' 500GB 5400 RPM HD (the WD Scorpio Blue), the increase in performance is remarkable when going to a good 7200 RPM HD like the 7K500.

I don't expect the Seagate 7200.5 to be better than the Hitachi (but I hope I'm wrong), at least, not until the XT Hybrid version is available and then, I would still hold out for the terabyte XT version anyway.

You will be very happy with the Hitachi, but if you're able to get the 500GB XT, you cannot be happier until you spend 4 times the money to get an SSD.

 

This is good information all of you are making available on this thread. Thank you!

Do you really think the 500GB XT is that much better than the Hitachi 7K500? I'm about to install my new Hitachi today! Should I hold off and exchange it for the XT?

 

Have a look at this review, it shows you how much faster the XT is than WD Scorpio Black 500GB.

WD Scorpio Black is expected to be slightly faster than 7K500.

I would recommend the XT over the 7K500. It's a lot faster.

 

Yes, the XT in most cases is faster than every other notebook platter-based drive on the market. Our real world testing showed this very clearly.

 

so does anyone have any idea of when its available and are there any benchmarks? I doubt its going to come close to 7K500.

 

If anyone sees one in stock somewhere in Europe please post here or send me PM.

 

NewEgg was the first reliable source for the XT, wonder if it will be the same for these??????

Edit; on a side note

 

Am I looking at the wrong thing? Looks like hte 7200 rpm drive does a number on the 5400 rpm one in that review.

 

You're right the WD5000bekt does a lot better than the 5400rpm drive in that review.

The difference between Momentus XT and a 7200rpm feels just as big, mainly because applications start almost instantaneous with the XT.

 

Any news on that one?
