Seagate's Savvio 15K hard disk drive

Seagate claims that its newest 2.5-inch 15K-RPM hard drive is the fastest in the world

Seagate Technology has announced what it claims to be “the world’s fastest hard drive” – the Savvio 15K with a seek time of a mere 2.9 ms. The new 15K-RPM addition to the Savvio family offers a number of advantages over 15K-rpm 3.5-inch drives including size and weight (due to 2.5-inch form factor), 30% decrease in power consumption (5.8 watts at idle), and reliability (1.6 million hour MTBF).

 “Seagate is committed to delivering solutions that will meet the needs of today’s demanding IT environment, and no product demonstrates this better than the Savvio 15K drive,” said Sherman Black, senior vice president and general manager, Seagate Enterprise Compute Business. “The development of the 2.5-inch Enterprise form factor represented a new way of thinking. Now, with the added number of performance and capacity choices offered, many of the leading enterprise system makers are transitioning from 3.5-inch to 2.5-inch form factor enterprise solutions.”

The move to small form factor enterprise disk drives was driven by data center requirements for greater storage performance density while focusing on lowering power consumption and cooling costs.

“The trend in IT is to scale down the physical size of components while scaling up capacity and performance,” said John Rydning, IDC’s research manager for hard disk drives. “Seagate’s first generation 2.5-inch 15K-rpm HDD is fitting with this trend, delivering fast I/O performance in a small package to meet the needs of demanding server applications.”

The Seagate Savvio 15K drives are shipping today in 36GB and 73GB capacities through OEM customers. HP is now shipping Proliant systems with 15K Savvio drives. The Savvio 10K.2 drive will launch in the channel this quarter as a replacement product for Savvio 10K.1 and as a transition path from Cheetah 10K.7 drives.

Companies are going to stop bothering with making faster traditional disk drives now that Solid State Drives (SSDs) are just around the corner. SSDs are the same price as this 15K rpm disk drive or possible slightly higher, but prices will drop quickly and capacities will increase quickly while they are many times faster and use a fraction of the power consuption.

Anandtech and Dailytech have covered this:

Current problem with SSD is the write speeds. They write very slowly compared to server class drives. Seek and Random Access time is great, but not so great on the Write time, and with lots of writing done to servers every second, SSD's can't keep up right now. Servers are going to stay magnetic for the time being.

SSDs will not even have 50% market share in 7-10 years

Faster traditional drives are and will continue to be produced for a long time. Cache and interface speeds definitely will increase and Hybrid HDDs will be the norm. The SATA specification already increased from 1.5Gbits to 3.0 Gbits and 6.0 is coming.

This is a great advancement as it allows more drives to fit in a smaller space while using less power and does not impact performance.

I'm not so sure about that. Other than increasing storage capacity, traditional hard drives have stagnated.

The only reall selling point is the cost per GB of the new drives. But if a user only needs 200 GB, why buy a terabyte size drive?

The unit cost to manufacture a hard drive isn't going to get a whole lot cheaper in the future. There aren't any more economies of scale to take advantage of, and there is no way to reduce the cost of the raw materals and mechanical components a HD requires.

Flash memory, on the other hand is much less technologically mature, new flash technologies and manufacturing methods are signifigantly improving speed and capacity.

Us nerds always forget that the typical computer isn't pushed that hard. Most computers sold have Windows, Office and internet explorer installed, and thats all they EVER have installed. 100GB will be fine for this type of computer, for its entire operating life. In a couple years 100 gb flash drives will give comparable performance and price to platter based drives. As soon as that happens, its all over.

You can make the interface as fast as you want. Its not the interface thats slowly down regular hard drives. Its the fact that the platter only spins so fast. ATA100 is more than enough bandwidth for any regular hard drive. The only thing SATA has given us is thinner cables, NCQ, and a few other minor improvements to the efficiency of the drive getting data off the disc. The only thing that will make traditional hard drives faster is to pack more data in less space.

If you only look at sustained throughput then you are correct, but you are forgetting that the drives also have a decent amount of cache on them that a slower (shared) ATA100 bus is slowing down considerably. If you actually use both connections on the ATA100 interface, then you'll run out of bandwidth even on sustained throughput (some drives can do a sustained throughput of over 80Mb/sec), and they keep getting faster.

The new vertical magnetic recording that Seagate and others are now using increases the data density quite a bit on the platters and that runs up the sustainable data rate (until a seek is required anyway).
