Product Description
IBM 3305 6 TB 7,200 rpm 12 Gb SAS NL 3.5 Inch HDD
IBM 3305 6 TB 7,200 rpm 12 Gb SAS NL 3.5 Inch HDD feature (#3305) providing one 12 Gb SAS disk drive formatted with 4,096 (4K) byte sectors (4Kn). This is a nearline (NL) SAS HDD designed for high-capacity, cost-effective bulk storage in compatible enclosures. Note that when installed in a Storwize V7000 (Gen1), it operates at a maximum data transfer rate of 6 Gb/s due to system limitations, despite the 12 Gb/s interface capability.
It is intended for use in 12-bay LFF enclosures within the IBM Storwize V7000 Gen1 family, offering reliable performance for capacity-optimized workloads with hot-swap support via the included carrier.

Configuration Options
The base offering is a single drive (#3305). Common associated IBM options for Storwize V7000 Gen1 environments include:
- Drive Fillers/Blanks: For unused bays to maintain proper airflow and system cooling
- Other Drives: Intermix with supported SAS/SSD drives in the same enclosure (e.g., 10K/15K SAS for performance tiers, smaller NL-SAS capacities)
- No additional adapters or licenses required for basic use
These enable straightforward, incremental high-capacity additions in compatible 12-bay LFF setups.
Compatibilities
The IBM 3305 6 TB Nearline SAS HDD is compatible with:
- Enclosures: IBM Storwize V7000 Gen1 12-bay LFF models:
- Control Enclosures: 2076-112 (LFF), 2076-312 (LFF with 10 Gb iSCSI/FCoE)
- Expansion Enclosure: 2076-212 (12 x 3.5-inch LFF)
- Systems: Storwize V7000 Gen1 (2076-1xx/3xx series); leverages full Spectrum Virtualize features including virtualization, thin provisioning, Easy Tier (for tiering with SSD/10K SAS), RAID 0/1/5/6/10, FlashCopy snapshots, and remote mirroring.
- Operating Systems / Servers: Broad support via Storwize V7000 connectivity (8 Gb FC, 1 Gb/10 Gb iSCSI/FCoE); compatible with major OS including Microsoft Windows Server, Red Hat/SUSE Linux, VMware vSphere/ESXi, IBM AIX, Oracle Solaris, HP-UX.
- Restrictions: Primarily for 12-bay LFF enclosures in Gen1; limited to 6 Gb/s effective speed in these systems; not for SFF-only bays or later generations (e.g., Gen2/Gen3 use different codes like AHD6 for similar 6 TB/10 TB NL drives); ensure current firmware supports the drive for reliability.
This provides economical, high-density capacity expansion in legacy Storwize V7000 Gen1 configurations.
The unit comes with a 60-day warranty for added assurance.
