What is high-capacity storage?

From small offices to large enterprises, the act of setting up a local storage solution is often a balancing act between cost, capacity, and performance. High-capacity storage is data storage optimized for cost per capacity ($/GB). High-capacity storage solutions are designed to accommodate Tier 2 workloads (or higher), such as virtual machines, backups, email, and test/dev environments.

People also ask:

1. What are the benefits of high-capacity storage?

The benefits of deploying your own high-capacity storage solution include:

  • Reduced storage costs
  • The ability to hyper-consolidate large volumes of data
  • The flexibility to optimize storage costs by storage tier
  • Optimal storage capacity and performance for Tier 2 workloads

2. What are high-capacity storage use cases?

High-capacity storage is best used for applications such as:

  • Disaster recovery for Tier 2 apps
  • Backups, snapshots, and mirroring
  • Multi-cloud test/dev workload consolidation
  • Policy-based VM-tiering

3. What is QLC Flash?

Quad-level cell (QLC) flash is a capacity-optimized NAND memory technology that delivers a per-terabyte cost that matches or beats hard-disk drives (HDDs).

4. What are the differences: QLC vs. SLC vs. MLC vs. TLC?

QLC flash is the latest in a long trend of squeezing more bits per cell within a NAND flash device. Here’s a brief overview of how the technology has evolved over time:

  • Single-level cell (SLC) flash: One bit per cell, two possible voltage states
  • Multi-level cell (MLC) flash: Two bits per cell, four possible voltage states
  • Triple-level cell (TLC) flash: Three bits per cell, eight possible voltage states
  • Quad-level cell (QLC) flash: Four bits per cell, 16 possible voltage states
