SSD vs HDD for Enterprise Servers: Performance Guide

SSDs win decisively on speed, but HDDs still have a place in enterprise storage. Here's how they actually compare on performance, capacity, endurance, and cost — and how to deploy each in an HPE ProLiant server. Last updated: 2026 C

Understanding Drive Writes Per Day (DWPD) in HPE Solid State Drives

Drive Writes Per Day (DWPD) is the single most important number for matching an SSD to your workload — it tells you how much you can write to a drive, every day, before it wears out. Here's what DWPD means for HPE SSDs, and how to cho

Comparing Solid State Drives (SSD) and Hard Disk Drives (HDD) in HPE Server Systems

SSDs and HDDs each still have a place in HPE servers — the trick is knowing which factor matters for your workload. Here's how they compare on performance, durability, capacity, and cost, and how to choose. Last updated: 2026 The ch

Understanding SSDs: Single-Level Cell vs Multi-Level Cell

The type of NAND flash inside an SSD — SLC, MLC, TLC, or QLC — sets its endurance, capacity, and cost. Here's what the bits-per-cell trade-off really means, and how it maps to enterprise HPE drives. Last updated: 2026 Every so

Understanding Spindle Speed and Choosing the Right HPE Server Hard Drive

Spindle speed — 7.2K, 10K, or 15K RPM — is one of the main things that separates HPE hard drives. Here's how it affects performance, which speed suits which workload, and the one question to ask before you even pick an RPM. Las

Understanding Data Transfer Rate in Hard Disk Drives

A hard drive's data transfer rate is easy to misread — the big interface number (6 or 12 Gb/s) isn't the speed you'll actually get. Here's what really determines HDD throughput on an HPE server, and the sustained-vs-burst distinction

Exploring the Impact of Rotational Speed on HPE Hard Disc Drive Performance

Rotational speed is why a 15K hard drive feels snappier than a 7.2K one — but it only affects part of the delay, and the effect is measurable in milliseconds. Here's the physics of how RPM shapes HPE hard drive performance. Last upda
