What Is Disk Prices (US)?
Updated
Disk Prices (US) is a price-comparison site that lists hard drives, SSDs, and other storage media sold on Amazon, sorted by price per TB (with price per GB also shown) so you can compare value across capacities and product types. It doesn't sell anything itself; it earns money through paid affiliate links. It's most useful when you want to judge cost-efficiency across many Amazon listings at once rather than browse one product page at a time.
What the site actually does
The site pulls listing data from Amazon storefronts and presents it as a sortable table. Each row shows:
- Price per GB and price per TB — the primary sorting signal
- Price and capacity of the item
- Warranty where the listing states one
- Form factor and technology (for example, 3.5" internal, M.2 NVMe, LTO tape)
- Condition (new or used)
- An affiliate link to the Amazon listing
Because the default order is price per TB, the cheapest rows at the top are often high-capacity tape media rather than consumer drives. In the current listing, for example, LTO-9 tape cartridges at 18 TB appear at roughly $4.89–$5.56 per TB, ahead of most flash and drive products. That's a sorting artifact, not a recommendation — tape is a backup/archive medium and needs a compatible drive.
Coverage and filters
The page exposes filters for data source (Amazon US, UK, Germany, Spain, France, Italy, Canada, Australia, India, Sweden, Ireland), condition, capacity range, and a long list of product categories:
| Group | Examples |
|---|---|
| Rotational drives | External 3.5"/2.5", internal 3.5"/2.5", hybrid, SAS |
| Solid state | External SSD, internal SSD, M.2 SATA, M.2 NVMe, U.2/U.3 |
| Memory | DDR5 and DDR4 in UDIMM, SODIMM, and RDIMM forms |
| Removable flash | microSD, SD, CompactFlash, CFast, CFexpress, USB flash |
| Optical and tape | BD-RE, BD-R, DVD-RW, CD-RW, LTO-3 through LTO-10 |
This breadth is the main differentiator: you can compare a microSD card, an NVMe drive, and an LTO tape cartridge on the same cost-per-TB scale, then filter down to the category you can actually use.
How to use it for a buying decision
- Pick your data source so prices and currency match where you can buy.
- Filter by category and form factor first — this removes media you can't use (tape without a tape drive, SAS without a SAS controller).
- Set a capacity range to exclude tiny or oversized items that skew the per-TB math.
- Sort or read by price per TB, then check the warranty and condition columns on the shortlisted rows.
- Follow the affiliate link to confirm the live Amazon price, seller, and shipping before buying — the table is a snapshot, and Amazon prices change.
Common pitfalls
- Per-TB ranking favors bulk and tape. A 20-pack of LTO cartridges will always beat a single consumer SSD on this metric; filter by category before drawing conclusions.
- Multi-packs distort capacity. Rows like "18 TB x20" show the per-unit capacity but a total price for the pack — check the multiplier before comparing.
- Used and new are mixed unless you filter by condition; a low per-TB price may reflect used stock.
- Warranty is only shown when the listing states it, so a blank cell doesn't mean no warranty.
When it's the right tool — and when it isn't
Use Disk Prices (US) when you already know the category and form factor you need and want to find the best cost per terabyte across many Amazon listings, or when you're curious how storage types compare on a single scale. Skip it if you need spec-level detail (endurance ratings, controller models, sequential speeds), need a retailer other than Amazon, or want current stock and delivery estimates — those require opening the linked listing. The site also states it is supported by affiliate links, so treat its ordering as a price signal, not an endorsement.
