Toshiba Announces AL14SX Series 2.5-inch 15K RPM Hard Drives
Toshiba Corporation's Storage & Electronic Devices Solutions Company today announced the launch of AL14SX Series, new additions to its line-up of enterprise performance hard disk drives (HDD) for mission critical server and storage applications. Sample shipments start today.
The AL14SX Series of 15,000RPM 2.5-inch drives features a 12 Gbit/s SAS interface. Available models are 4K native (4Kn) model and 512 emulation (512e) model that feature Advanced Format Sector Technologies, and 512 native (512n) model optimized for legacy applications and hypervisor environments. The AL14SX Series delivers a suitable choice for customers' diverse applications.
The AL14SX Series is available in 300 GB, 600 GB and 900 GB capacities. The 900 GB model offers a 50% increase in maximum capacity from the 600 GB of the predecessor AL13SX Series. The 4Kn and 512e models also delivers an approximately 19% increase in sustained data rate, pushing it to 290 MB/s, and an approximately 28.7% improvement in power efficiency (W/GB). These improvements in capacity, speed and power-saving contribute to a lower total cost of ownership (TCO) for the server and system.
Customers also can select models supporting Sanitize Instant Erase (SIE), which realizes fast invalidation of data recorded on the disks, allowing for efficient disposal and reuse.

Enterprise-grade SSD are still hugely expensive.
Current 960GB Toshiba SAS SSD costs around 1100 EUR.
This 900GB SAS HDD will cost around 300 EUR.
For data storage, there are plenty of 3.5" SAS and SATA (like WD Gold/RE) options.
A WD equivalent for Toshiba's 15K drives was called XE and has been discontinued.
It's not easy to make a 3.5" 15K drive, but the actual reason behind 2.5" HDD popularity is much simpler.
2U rack is 3.5" high, but a 3.5" HDD is 4" wide, so it won't fit mounted vertically.
As a result a 2U can hold just 12x 3.5" drives, but up to 24x 2.5". :)

Additonally, wiping a SSD adds a lot of wear. Also you can't full wipe free space as i stated above with an SSD and even if you could that is a ton of wear. When I had an HDD as my main drive i wiped free space weekly. If that was even possible on an SSD you would wear it out significantly.
Also there is no way to use magnets or degauss an SSD like you can with a HDD. You can instantly trash a HDD but you can't do that with an SSD.
