SKU CH-0ST8-5HNPR

A 12 TB SAS hard drive spinning at 7,200 RPM in a 3.5-inch bay for high-capacity desktop storage

  • 12TB capacity for large-scale storage needs
  • 7200RPM rotational speed enables fast data access
  • SAS 12.0Gbps interface delivers high transfer rates
  • 5in 1.0in LFF form factor fits standard drive bays
  • 243/255 MB/s sustained throughput supports demanding workloads

12 TB SAS drive for servers

The Dell 0F29535 is a 12 TB internal hard drive built for 3.5 inch bays in enterprise servers and storage arrays. Its 7200 RPM spindle speed and SAS 12.0 Gbps interface suit workloads that demand high capacity with consistent throughput.

Tool-less tray mounting

The drive fits standard 3.5 inch large-form-factor trays with a 1.0 inch z-height and connects through a single SAS-3 backplane connector. No cables or adapters are required, but the host controller must support SAS-3 12 Gbps signalling or the drive will negotiate down to a slower link speed.

12 Gbps SAS-3 interface decides fit

The electrical interface is SAS-3 at 12.0 Gbps, so the drive only delivers its rated 243 to 255 MB/s sustained throughput when paired with a compatible 12 Gbps controller or expander. Buyers whose backplanes or HBAs are limited to 6 Gbps SAS-2 will not see the full performance this drive is designed to provide.

Questions about this item

How do I verify the drive is performing at the 243 MB/s sustained throughput after installation?

Run a sequential read test with a tool such as CrystalDiskMark or fio and confirm the result is near 243 MB/s; the drive's average seek time should also measure around 8.0 ms.

What comes in the box with the 0F29535 and what must I source separately?

The drive itself is supplied; you will need to provide a SAS 12.0 Gbps cable, a compatible backplane or HBA, and mounting screws for the 3.5-inch bay.

Which sector size version should I choose for a new RAID array — 512 or 512e?

Choose 512e for modern controllers and operating systems; it presents 4 KB physical sectors while emulating 512-byte logical sectors for compatibility.
