Seagate Momentus 120GB 2.5" HD 174

Posted by CmdrTaco from the i'll-tell-you-where-to-stick-it dept.
VL writes "A mobile user can never have enough storage space, so we checkout Seagate's latest solution for notebooks. Seagate's warranty is among the best I've seen at five years, which is much better than the one year or so that comes with laptops (and thus their hard drives) or the three years offered by others. Performance is what this drive is targeted to excel at, an it seems to do so fairly well. In our tests we saw it do markedly better than the Hitachi drive in most tests that focused on performance. Battery life was slightly lower than that of the Hitachi drive but within 2% of that drive. "

          Or, put another way, when you are shopping for hard drives you can only buy what you can buy two of at the time of purchase. Simple as that. Then, using any number of methods, you can at least have all your data on 2 drives at once.

        I travel fairly often and have a pretty extensive music collection on record and CD (around 1000 CDs and about half that of records). I personally like to have ALL or as much of this music with me whenever possible. My MP3 player is only a 20 gig Creative Zen, however I would like a larger capacity player, simply because I could then store all or most of my music (should I get round to ripping it all).

        When I do travel, it tends to be for months at a time rather than a couple of weeks and so it's not practical carrying 1000 CDs and 500 records.

        It's not about listening to 40 days continuous music but having the music to hand.

        Currently I know there's always going to be a time when I want to listen to a particular song or band and I don't have it with me. Had my MP3 player had a 120 gig hard drive, then I know I could take all my music with me.

What is remarkable about the Seagate drive is that it runs at 5400 rpm while maintaining a similar energy consumption to a 4200 rpm drive. Its more hard drive bang for your energy buck.

Anyone found a source for these new magic drives? I remember years back with my black powerbook with its "huge" 8gb drive, finding that IBM had made a massive 23 gb drive and having to search high and low to find the ONE retailer that had just TWO of them in stock. I still say I should have bought both and ebayed the other and made a killing.

    If someone has found a few sources for them, can you report back on prices so we know how bad it's gonna sting? (that 23 was over $800 at the time, but worth every penny!)
    • 2.5in looks like the future of hard drives, laptop or server, at least if you listen to HP [hp.com]. So far you can only get 72GB in Serial Attached SCSI 2.5in. Wonder how long they'll keep up 3.5in drives, or wether they'll keep those around for bigger servers.
    • LBA48 won't be a big deal for laptops, because this problem has already been solved for 3.5" drives and desktops, and that hardware (Firewire bridge chips) and software is already there. It's not like Windows has one driver for 3.5" ATA devices and another for 2.5" ATA devices. The only part that is specific to laptops that I can think of it the BIOS. I guess it's possible that the BIOSes in even recent laptops haven't been updated to boot from LBA48 devices simply because they didn't have to. But I expect
      • Remember though that there are three important factors in play here.

        (1) the IDE controller chip has to have LBA48-aware firmware. This same issue applies to firewire-to-ide bridge boards in use in many firewire enclosures. I have a handful of bridge boards here that are NOT LBA48 compliant and will only detect 128gb at most. Manufacturers are still making bridge chips that are not LBA48, sadly.

        (2) the software you speak of, the ATA driver in your OS, must also be LBA48. I don't see this being a problem
        • Due to how the LBA48 standard was implemented, a controller chip isn't "LBA48" or not. You just write some registers twice. You can make any controller chip do LBA48 with the right software.

          Bridge chips are problematic since they are self-contained and you can't necessarily update the software on them (and they might be out of code space), but laptops don't use bridge chips, they just have an ATA interface that is accessed by the main CPU. Fix the code on the main CPU (OS or BIOS) and you're there.
          • Explain then why do I have ATA controller cards here that don't support large drives, and yet I can replace them with newer controller cards and suddenly get large drive support?? This appears to be an open-and-shut case for ATA controllers being able to influence LBA48 compliance.

            And talking of bridge boards, you can't necessarily update the software on them is foolish because close to 100% of bridge boards have flashable firmware. All 13 of my boards, from 5 different manufacturers, are flashable. I've
            • the reason you can replace them with newer ones that have large drive support is because:

              There's more profit in selling you a new card than letting you update the old ones! Ta-Daa!

              Anyway, you can just plain skip the logic anyway. I've written ATA drivers for controllers before. I know how it's done, and I personally have done it and know that there is no restriction to what controllers can have LBA48 software written for them.

              Go get the spec from t13.org ourself. All you have to do is write 4 registers twic
              • Some of the dialog that went back and forth between me an an engineer at Oxford Semiconductor (makers of the popular "911" firewire chipset)...

                It was indeed the board that was the problem. After talking with Mr Brown at OS I have checked the boards, and four of the nine 142AS boards were the older revision, including the one I sent to you. (2.0) They lack a small chip "LVC02A" which is what allows them to do LBA48. Apparently the Maxtors do > 128gb by some method other than LBA48, so they all work fine
                • Like I said, I already told you that bridge controllers might be different. That doesn't mean there is LBA48 hardware.

                  As to the extra chip, a 74LCV02A is just a quad 2-input NOR gate. I'm not quite sure why this chip would help them do 48-bit addressing.

                  I would more expect it is used to block the signal coming from the DMA controller to the drive, so that they can run their DMA controller multiple times in a row without the controller signalling to the drive that the transaction is complete after the first
    • What happens when they make a 140gb 2.5" HDD?

      We'll find out soon: 160's are due by the end of the year. I already upgraded my 60 to a 100 last year, and it's full already, so I guess I'll find out.

      Anyone found a source for these new magic drives?

      Newegg has had 120 gig laptop drives for a while now. It's listed at $263.75, so you might want to shop around.

    • What happens when they make a 140gb 2.5" HDD? I have had headache after headache with desktop systems and firewire enclosures that were not fully LBA48 compliant, and so they would detect 160, 180, 200, and 250gb HDs as 128gb. (or not at all...)

      This is (almost) a non-issue.

      Windows 95/98/ME is dead. Every OS that isn't DOS-based completely ignores the BIOS drive specs, and detects the specs on it's own, at boot time. You can put a 300GB drive in a 486, and it will boot the OS (as long as the loader is in t

    • It seems like every time IDE drives start to run into an addressing problem, they come up with a new model that's a few times bigger and lasts for another couple of years

      Out of curiosity, is there a technical reason why they don't just jump to LBA64 or LBA80 or something else that'll be good for another few decades? Note: "to sell more hardware" isn't a technical reason. :-)

      • Old style is LBA32, iirc. (correct me if you know better)

        They only use 30 of those bits for block addressing. Not sure on the other two, probably read/write flag and something else.

        2 ^ 30 = big number. It's signed, so we only can use 2^29 of it for positive numbers. There are 256 bytes per HD sector, so add another 8 to the 29 (2^8=256) and you will find 2^37 = 137,000,000,000 or so, which is 128gb, and there is your old LBA30 limit.

        LBA48 adds 18 bits. That's about 262,000 times the capacity.

        I know Moor
  • I put this in my Dell D800 laptop and XP Pro couldn't format it. I took it out, put it in an external box with an AC power supply, plugged it into the USB port, and it formatted fine. Then I put it back in the D800 and it works fine there too. This puzzles me, perhaps someone can help me understand it.
  • I emailed seagate asking for more specs and availaibility. Looks like he picked a very strategic time for a vacation!

    I will be out of the office starting 09/10/2005 and will not return until
    09/19/2005.

    I will have limited access to email and voicemail. If your matter is
    urgent, please contact John Paulsen at (831) 439-2499 or

  • I just ran HD Tach on my 7200rpm 60GB Hitachi 7K60 in my laptop and the Seagate at 5400rpm nearly matched it. I had the same 40MB/s max, 33MB/s average read speed and a slightly faster 14.6ms seek time. Most likely the Seagate can keep up because of the higher density. Even though it spins fewer times in a second, the heads still see the same amount of data.

    So, this drive is actually impressive. I paid $200 for my 60GB, I'd consider another $50 for double the space at the same speed a very good deal.
