What are the key performance specs of the Dell H8DG4?

Sequential read: 4200 MB/s (128KiB), random read: 600K IOPS (4KiB). Sequential write: 1200 MB/s, random write: 55K IOPS. SAS 24Gbps interface ensures high throughput in enterprise RAID configurations.

Is the H8DG4 compatible with Dell PowerVault enclosures?

Yes, validated for PowerVault ME4 Series and MD14xx enclosures per Dell support matrices. Uses Samsung MZILG960HCHQAD3 OEM model with DSG9 firmware for full interoperability.

What workload is this SSD optimized for?

Read Intensive with 1 DWPD rating, ideal for virtualization, databases, content delivery where reads exceed writes. Provides consistent performance without write amplification penalties.

Does it support hot-swap in servers?

Yes, 2.5-inch SFF hot-plug design compatible with Dell PowerEdge front bays and storage backplanes. Dual-port SAS enables redundant paths for HA environments.

What is the underlying NAND and sector format?

TLC NAND flash with 512e advanced format emulation. Samsung enterprise controller ensures power-loss protection and end-to-end data integrity.

Is it backward compatible with older SAS?

Fully backward compatible with 12Gbps SAS infrastructure while optimized for 24Gbps, allowing incremental upgrades without controller replacements.

Product overview

The Dell H8DG4 is a 960GB SAS 24Gbps Read Intensive solid-state drive designed for enterprise storage environments, featuring TLC NAND flash and 512e sector format in a 2.5-inch SFF hot-plug form factor. It provides sequential read speeds up to 4200 MB/s and random read performance of 600K IOPS, with 1 DWPD endurance and 2.5 million hours MTTF for reliable operation in read-dominant workloads. Optimized for Dell PowerEdge servers and PowerVault ME4/MD14xx storage arrays, this SSD supports dual-port SAS connectivity for high availability and backward compatibility with 12Gbps SAS infrastructure. Key applications include virtualization hosts, database querying, content delivery networks, and analytics platforms where consistent low-latency reads are critical. The drive's power-efficient design and advanced error correction ensure stable performance under sustained loads, enabling scalable storage upgrades without full hardware overhauls. Integration with enterprise RAID controllers and HBAs facilitates fault-tolerant configurations, while hot-swap capability minimizes downtime during maintenance.
