How to Check Current SSD Prices and Find the Best Price per GB/TB

To judge whether an SSD is actually a good deal, compare price per GB or per TB, not the total sticker price. A $60 500GB drive and a $100 1TB drive look close in total cost, but the second is far cheaper per gigabyte. Use a price-comparison tool that ranks drives by $/TB — PricePerGig.com does this for Amazon.com (US) and 20+ other stores across 11 countries — then filter by capacity, interface, and form factor so you're comparing like with like.

Why price per GB/TB matters more than total price

SSD listings are usually sorted by total price, which favors small, cheap drives. The value metric is:

Price per GB = Total price ÷ Capacity in GB
Price per TB = Total price ÷ Capacity in TB

A 2TB drive at $100 is $0.05/GB ($50/TB). A 1TB drive at $70 is $0.07/GB ($70/TB). The 2TB drive wins even though it costs more up front. Larger capacities almost always have a lower $/TB, so the "cheapest" listing is rarely the best value.

Step-by-step: find the best SSD price per TB

1. Open a price comparison site such as PricePerGig.com, which aggregates live Amazon.com (US) listings and ranks them by price per GB/TB with a ValueScore.
2. Set your region/store. The site defaults to your location but lets you switch via a dropdown across 20+ stores in 11 countries (Amazon, eBay, Newegg, Seagate, and regional retailers like Overclockers.co.uk, Alternate.de, and Newegg.ca).
3. Filter by type. Choose "SSD" (or "HDD, SSD (inc. NVMe)" for everything) to exclude hard drives, flash drives, and memory cards.
4. Set a capacity range. Use the "At Least" and "Up To" filters (from 1GB up to 32TB) to match your needs — e.g., at least 1TB, up to 4TB.
5. Narrow by interface and form factor. Select SATA, PCIe (NVMe), or USB; then pick a form factor like M.2 2280, M.2 2230, or 2.5".
6. Set a price range ($1–$500+) and, if you want, a warranty minimum (1 month+ up to 5 years+).
7. Sort by $/TB and read the ValueScore to spot the best value, not just the lowest total price.

Expected result: a ranked list where the top entries give you the most storage per dollar for your chosen capacity, interface, and form factor.

How interface and form factor change the price

The same capacity can carry very different $/TB depending on the spec:

If you don't need NVMe speed, a SATA or 2.5" drive often gives a lower $/TB. If you're upgrading a laptop, match the M.2 length (2230 vs 2280) before comparing prices — a cheaper drive that doesn't fit is no deal.

Are used, refurbished, or open-box SSDs worth it?

They can be, if the discount is large enough to offset the risk. The site lets you filter by condition and by warranty length (1 month+ through 5 years+), so you can require a minimum warranty before comparing. A used drive with no warranty should be meaningfully cheaper per TB than a new one to be worth considering — otherwise the new drive's warranty and remaining life win.

Common pitfalls when comparing SSD prices

• Sorting by total price instead of $/TB — this hides the best value.
• Mixing interfaces or form factors in one comparison — a SATA and an NVMe drive at the same capacity aren't directly comparable.
• Ignoring capacity tiers — $/TB usually drops as capacity rises, so a 2TB or 4TB drive often beats two smaller ones.
• Paying for brand or speed you won't use — if your workload is light, a cheaper SATA drive at a lower $/TB is the smarter buy.
• Forgetting the store/region — prices differ across Amazon, eBay, Newegg, and regional retailers, so check the marketplace that actually ships to you.

Quick decision checklist

• Decide your minimum capacity and interface/form factor first.
• Filter to new (or set a warranty minimum) unless the used discount is large.
• Sort by $/TB, not total price.
• Compare the top 3–5 results across at least two stores in your region.
• Buy when the $/TB is at or below the typical level for that capacity and interface.
