Frequently Asked Questions

What does 512e sector emulation mean?
512e (512-byte emulation) means the drive uses 4K physical sectors internally but presents 512-byte logical sectors to the host — maintaining compatibility with older SAS controllers and operating systems while using modern high-density NAND formatting internally.
Is the 01LU840 suitable for use in IBM Storwize or FlashSystem arrays?
The 01LU840 is an IBM SAS HDD — suitability depends on the specific IBM storage system's qualified drive list. Verify IBM QDL for your Storwize, FlashSystem, or DS series system before ordering to confirm compatibility.
How does the 256MB cache improve performance compared to lower-cache HDDs?
The 256MB cache significantly improves sequential read-ahead and write buffering performance compared to 128MB-cache alternatives, benefiting large-block sequential workloads like backup, archiving, and streaming data applications.

The IBM 01LU840 delivers 14TB of enterprise-validated SAS Nearline capacity in the 3.5-inch LFF form factor — providing the bulk storage density, dual-port redundancy, and 256MB cache performance that make it a practical high-capacity HDD choice for cost-conscious IBM storage administrators expanding archive, backup, and capacity tier infrastructure.
