Toshiba Corp. has introduced its latest breed of 15K hard disk drives that increase performance and capacity of enterprise-class hard disk drives aimed at mission-critical applications. The new storage solutions will offer all the latest technologies and formats, but will hardly be able to offer competitive performance compared to solid-state drives.

Toshiba AL13SX series comes in 300GB, 450GB and 600GB capacities, and delivers high performance thanks to 15K RPM spindle speed while supporting industry standard 512n sector lengths in a 2.5” form-factor. The 4K native sector and 512e emulation models of the drives include Toshiba’s persistent write cache technology for improved data integrity and performance. Overall, the AL13SX series supports high storage density, saving rack space and reducing mission critical storage footprint and operational burden for enterprise customers.   

The new 15K hard disk drives sport 64MB cache as well as SAS-6Gb/s interface. Toshiba states 2ms average latency, 2.7ms average read seek time and 2.95ms average write seek time. The drives consume 5.8W in idle mode and 9W in active mode.

“The 15,000 RPM disk continues to be the backbone of mission critical IT operations. Toshiba’s AL13SX doubles available capacity while preserving the low-latency and energy efficiency customers require. While older 3.5-inch 15000 RPM disk drives are withdrawing from the market, the AL13SX provides a clear migration path to 2.5” models with the same 600GB capacity and lower latency for improved performance with a significant power savings – a real win-win for the important mission-critical storage category,” said Don Jeanette, senior director of marketing at Toshiba ыtorage зroducts business unit.

While 15K hard disk drives cannot compete against solid-state drives in terms of performance, the may represent a good value for the market of relatively low-cost enterprise-class storage. For example, such drives are just what the doctor ordered when there is a need for mission-critical-class storage devices with massive capacity at a relatively affordable price.

Sample shipments of Toshiba AL13SX-series hard drives will start from the middle of March, 2014.

Unless there are some applications where a 2.5" FF is significant over a 3.5" FF, I can't see why they'd drop the FF size when increased HDD performance could be provided instead at the 3.5" FF.

Obviously enterprise HDDs are not intended to compete with SDDs. Eventually PCIe SSDs will fill all computers, which is a good thing. That however is a few years down the road.

Not sure PCI-E SSD's are a good thing in consumer drives, I actually downgraded from one to a normal SATA SSD. I had a OCZ Revodrive 3 X2 240gb and it was awesome for its speed once in windows but the boot times being a raid card was pathetic, It would have to load up it's own drivers on boot up so it took nearly as minute to get to desktop, Where as this Samsung 840 pro SATA boots in 10 seconds. If they dump the raid maybe I'll go back.

He is talking about the new SATA Express connector which runs the SSD over some PCI lanes and connects it with a SATA cable. This is a bit different from revodrive.

because spinning a ~3" platter vibration free instead of ~2" platter at 15.000 RPM is a LOT more difficult. the outer edge of a 3" platter would be traveling over 50% faster then that of the 2". (~60 meters a second instead of 40m/s)

basically the same reason we don't have 5.25" hdd's anymore(and never had many of those to begin with).

reliable would suffer greatly if the platters were much bigger then the ones used in the 2.5"models.

Yeah, all early commercially available HDDs were either FULL Height 5 1/4" or Half-Height (CD/DVD Drive size) 5 1/4". My 1st HDD was a 40MB 3650 MiniScribe Half-height 5 1/4" drive using using an 8-bit interface card using MFM with 2 cables (one for data; one for control info) connected between the HDD and controller card. I think most HDDs back then ran at 3600 RPM if I'm not mistaken. I had to buy and external case and run the cables out of my Tandy 1000 and into the external case which I sat on top of my PC, because I had both 5 1/4" bays filled with two 360K floppy drives. Ahhhh, memories....

Yeah, just did a google search and there is still info floating around the web on it!

Is interesting to remark how the price of a cheap SSD out there is almost the same as those 15K drives.
Reliability is another talk....
