The AL15SE Series of 10,500RPM 2.5-inch[1] drives features a 12Gbits/s[2] SAS interface. A 4K native (4Kn) model and 512 emulation (512e) model, both featuring Advanced Format Sector Technologies, are available in 600-gigabytes (GB[3]), 900GB, 1.2-terabytes (TB), 1.8TB and 2.4TB capacities. A 2.4TB model offers approximately a 33% increase in maximum capacity from the 1.8TB of its predecessor in the AL14SE Series. The drives also deliver an approximately 15%[4] increase in the sustained data rate, pushing it to 260MiB/s[5]. These improvements in capacity and speed contribute to higher capacities and performance improvements in servers and storage systems.


The 512 native (512n) model optimized for legacy applications and hypervisor environment is available in 300GB, 600GB, 900GB and 1.2TB capacities.


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.

[1] "2.5-inch" describes the form factor of HDDs. They do not indicate drive's physical size.
[2] Read and write speed may vary depending on the host device, read and write conditions, and file size.
[3] Definition of capacity: We define a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
[4] Comparison with AL14SE (4Kn and 512e) transfer rate: 226 MiB/s
[5] A mebibyte (MiB) means 220, or 1,048,576 bytes, and a gibibyte (GiB) means 230, or 1,073,741,824 bytes.
