Buy Cheap Hard Drives: Find the Best Deals in 2026

Looking to buy cheap hard drives? You're in the right place. BuyPerUnit compares 103+ hard drives, SSDs, and NVMe drives ranked by price per gigabyte — the only metric that truly shows you which drives offer the best value for your money.

Right now, the cheapest storage starts at just $0.018/GB, while the average across all drives is $0.071/GB. Whether you need bulk storage for backups or a fast NVMe for gaming, we help you find the best deal.

How to Buy Cheap Hard Drives (Without Getting Ripped Off)

1. Compare Price Per GB

A $150 4TB drive ($0.037/GB) beats a $70 1TB drive ($0.07/GB) in value. Always divide price by capacity to find the real cost.

2. Bigger = Cheaper Per GB

Storage follows economies of scale. 4TB+ drives almost always have the lowest price per gigabyte. Buy more capacity upfront to save long-term.

3. HDD vs SSD Tradeoff

HDDs are 2-5x cheaper per GB but much slower. Use HDDs for bulk storage (movies, backups) and SSDs for your OS and games.

4. Watch for Sales

Hard drive prices fluctuate. We update prices daily so you can catch the best deals. Bookmark this page and check back regularly.

Cheap Hard Drives vs Cheap SSDs: Which Should You Buy?

TypeTypical $/GBSpeedBest For
HDD$0.015-0.02580-160 MB/sBulk storage, backups, media libraries
SATA SSD$0.05-0.10500-550 MB/sOS drive, general use, laptops
NVMe SSD$0.04-0.123,000-7,000 MB/sGaming, video editing, fast boot

Frequently Asked Questions About Buying Cheap Hard Drives

What is the cheapest hard drive per GB right now?
The cheapest storage per gigabyte is currently $0.0183/GB. Large capacity HDDs (6TB+) typically offer the lowest price per gigabyte, while NVMe SSDs have become increasingly affordable with many models under $0.05/GB.
Should I buy a cheap HDD or spend more on an SSD?
It depends on your use case. For bulk storage (movies, backups, archives), a cheap HDD makes sense. For your operating system, frequently used programs, and games, an SSD is worth the extra cost — the speed difference is dramatic (10-50x faster).
Is it better to buy one large hard drive or multiple smaller ones?
One large drive is almost always cheaper per GB. However, multiple drives provide redundancy — if one fails, you don't lose everything. For important data, consider buying two drives and keeping backups on both.
When is the best time to buy cheap hard drives?
Black Friday, Cyber Monday, and Amazon Prime Day typically have the best deals. However, prices fluctuate year-round. We update our rankings daily so you can always find the current best value.
What brands make the cheapest reliable hard drives?
For HDDs, Seagate and Western Digital dominate the budget market. For SSDs, brands like Crucial, Kingston, Silicon Power, and TeamGroup offer excellent value. Samsung and WD Black are pricier but offer top-tier performance.

How We Find the Cheapest Hard Drives

BuyPerUnit calculates the price per gigabyte for every hard drive, SSD, and NVMe drive by dividing the current price by the storage capacity. This gives you the true cost of storage, making it easy to compare products of different sizes.

Products are ranked from best value (lowest $/GB) to worst. We update prices regularly from Amazon to ensure you always see current deals. Click any product to view the latest price and purchase directly.
