HGST, a Western Digital Company Ultrastar HE8 8000GB 128MB 7200RPM SAS Ultra 4KN ISE 128MB Cache 3.5-Inch Internal Bare or OEM Drives 0F23651
The HGST Ultrastar He8 8TB Enterprise Hard Drive (Model: HUH728080AL4200 / Part Number: 0F23651) is a high-capacity, helium-filled 3.5-inch mechanical hard drive engineered specifically for demanding, large-scale data center environments.
Core Technical Specifications
• Capacity: 8TB (8000GB)
• Rotational Speed: 7200 RPM
• Interface: 12Gb/s SAS (Serial Attached SCSI)
• Cache: 128MB
• Format: 4Kn (4K Native)
• Security Features: ISE (Instant Secure Erase) for rapid drive retirement/redeployment
• Form Factor: 3.5-inch
• Part Number: 0F23651

1. Hardware Interface Requirements
• SAS Controller: You must use a dedicated SAS Host Bus Adapter (HBA) or a SAS RAID Controller (e.g., LSI/Broadcom, Dell PERC, or HPE Smart Array) that supports 12Gb/s SAS speeds for optimal performance. It will also backward-compatible with 6Gb/s SAS controllers at reduced speeds.
• No Direct SATA: You cannot plug this drive directly into standard SATA ports on a server or desktop motherboard.
2. Operating System & File System Support (4Kn)
Because this drive features 4K Native (4Kn) sectors, your software stack must support large sectors:
• Windows Server: Supported natively in Windows Server 2012 and newer. Windows Server 2008 and older cannot boot from or use 4Kn drives.
• Linux: Supported natively in Linux Kernel 2.6.31 and newer (includes modern versions of RHEL, Ubuntu, Debian, and Rocky Linux).
• VMware ESXi: Supported natively in ESXi 6.7 and newer (used primarily for local datastores, not for boot drives).
3. Server Vendor Compatibility Examples
Most major enterprise server lines support this drive when configured with the correct SAS backplane and controller card:
• Dell PowerEdge: Supported in 13th Generation (13G) and newer servers (e.g., R630, R730, R740, T630) equipped with H330, H730, or H740 controllers.
• HPE ProLiant: Supported in Gen9 and newer servers (e.g., DL360 Gen9, DL380 Gen10) utilizing Smart Array P440ar or P408i controllers.
• Lenovo ThinkSystem: Supported across modern storage and rack servers equipped with ThinkSystem RAID adapters.
4. NAS Compatibility Warning
• TrueNAS / Unraid: Fully supported if the underlying server hardware uses an HBA card flashed to "IT Mode" (initiator target mode).
• Synology / QNAP: Many commercial desktop NAS units do not support SAS drives because they lack SAS backplanes and SAS controllers. Check your specific NAS model specifications to confirm it accepts SAS disks, not just SATA.
What is the exact model of the server or NAS you are planning to install this drive into?
