Your notebook will soon be able to store more extraneous things than ever

Fujitsu today announced the MHX2300BT series of mobile hard disk drives featuring impressive storage capacities of 250GB and 300GB, making them the first 2.5" PMR hard disk drives in the industry to attain these high levels of capacity.

PMR, or perpendicular magnetic recording technology, is essential to Fujitsu achieving the increased capacity per platter. PMR technology places the data bits standing on end so that more data can fit onto a disc, allowing for greater storage capacity while reducing corruption factor.

Additional benefits of the Fujitsu second-generation PMR products include best-in-class low power consumption at 1.6W, idle power consumption of 0.5W as well as high shock tolerance and near-silent operation. The 4200 RPM drives have a track to track seek time of 1.5ms.

"Due to our strong focus on innovation, Fujitsu remains at the forefront in promoting advanced technologies such as perpendicular recording and SATA, while at the same time continuing to meet the industry's insatiable demand for high-capacity products," said Joel Hagberg, vice president, marketing and business development, Fujitsu Computer Products of America. "Our commitment to R&D has not only spurred the development of the industry's first 2.5" 300GB capacity perpendicular hard disk drive, but it will allow Fujitsu to continue to achieve these aggressive milestones in advance of the rest of the industry."

Just last March, Fujitsu launched the first 2.5" Serial ATA hard disk drive to feature up to 200GB of storage space. The MHX2300BT series will begin shipping in the first quarter of 2007.

man, why not 7,200 rpm :(

with everything loading faster i'd gladly lose a few minutes of run time... i'm on battery so little the couple milli-amps wouldn't bother me one bit...

I wonder why no one has a drive with dynamic RPMs.

So, say when plugged in it could run at 7200, but on battery would drop down to 4200

Sounds like a good idea to me - that lets the power/performance be dynamic rather than being fixed. The OS could control that along with other power settings. I wonder if there is a reason that the RPMs are currently fixed for a given model?

What are you even talking about?
First, no matter what the density, a higher rotational speed will be faster.
Second, the density is the same for these drives as the biggest desktop HDDs.
Third, there is MUCH more data on a 3.5" disk than a 2.5". There's simply a greater area.
I don't know where you get your information, but you need to read somewhere else.

I think you misunderstood the post. At a higher bit density, all other things being equal, the head will pass over more bits per second than a disc with a lower bit density. Increasing the rotational velocity will also allow the head to read more bits per second, but will use more power, so will not be as desirable a solution in a laptop. Also 2.5" drives will have less distance for the head to travel from one edge of the disc to the other, ideally this could result in a lower seek time. High end SAS drives for enterprise servers are going to the 2.5" form factor with higher bit densities for all these reasons.

"seek time of 1.5ms."

Isn't that better then 15k rpm drives?

track to track seek time of 1.5ms.

Track to track is the important part.

Do some shopping around. You can find 7200 RPM notebook drives, but not in this size and they're expensive as crap.

7200-RPM drives for notebooks are something new. I think the OP was hoping for a 7200-RPM, 300-GB drive. That combination is not available (not even close), AFAIK.

Hitachi has announced the 7K200 will be released early next year.

200GB PMR and 7200RPM.

Best of both worlds for laptop users.

7200 rpm notebook drives have been around for years now. They have always been at smaller capacities then other drives available at the same time so their must be a technological reason why it takes longer to come out with faster rpm drives.

Considering that many people keep their labtop plugged in all the time, performce is much more important than battery life.

Also, laptops are becoming more common in business but not for travel/battery life purposes, but rather so employees have the option to take the work computer home so in these situations, performance rules over battery life.

It's the same reason that 5400RPM desktop drives had higher capacities than 7200RPM drives (at least when 5400RPM desktop drives were still common), and 7200RPM drives have higher capacities than 10K or 15K drives. Presumably because the drive head is not able to read data on as fine a scale when the platter spins at a higher speed (although someone can correct me if the reason is more complicated).

These drives will be slow for daily usage. I need at least 5400rpm. These drives are good for really light and portable storage to carry in a 2.5inch enclosure.

Yeah, you're such a POWER user. Squeeze in that extra 38sec. a day of productivity.

If you're a professional user, like a software developer, you'll send a lot of time constantly opening and closing software applications, maybe possibly making systems restarts. Trust me the extra delay from a slow hard drive becomes extremely annoying after a while and does slow down productivity.

Also what about people doing video editing, paying games etc?

People doing Video editing may use a laptop but professional only use extremely high performance machine to speed up processing. Those drives are probably not targeted at video editing but most probably for middle performance, high storage need. It is certainly not targeted to replace 30 drives raid array of cheetah 15k rpm drives ;)

A software developer may be compiling and re-compiling all day long, and this process is often I/O-bound on machines witih slower HDDs. So in this case, a faster HDD will be beneficial.

Any professional doing video editing on a laptop deserves the lost productivity they will see. Almost without exception, you can always get higher performance desktop machines than laptops. The laptop is not really good for high-memory, high-CPU load, high-IO tasks.

The seek times will be slow, but the large capacity should make throughput about as fast as a smaller (less dense) but faster-spinning drive. Once they start pairing these large platters with flash memory, you will have a system that has the best of both worlds: low latency flash to store the OS/applications, and the large magnetic platter to store movies, music and porn.

PS3 owners will be pleased. Didn't fujitsu also set the world record for the largest hard drive array? (remember arrays of hard drives in RAID adding up to several terrabytes)

Several terabytes is what, 4 or more 750GB drives? Not such a big deal anymore. Sure you don't mean petabytes?

I think it was for the highest density RAID array.

They used something like 24 of these 2.5" drives in a really small enclosure, producing several Terabytes of very fast access storage, despite the drives themselves being pretty slow.

And by fast I mean bandwidth-wise. latency is rarely affected (and in most cases actually goes up) when placing drives in a RAID system.

With Increase Storage density and better Flash memory pricing. Hard drive dont need to spin as fast to have the same transfer rate. And it could also have a bigger cache( 32M :) )

I generally like this direction. Lower Spin rate, more shock resistant, higher reliability, bigger cache. As Flash memory are getting increasingly cheaper. Hard disk will be used for general storage and Flash drive will be used as our main hard disk for boosting performance.

Of coz that is still a few years away.
