About Our Disk Prices Tools
The Disk Prices Tools is a free disk price comparison tool built for anyone shopping for hard drives, solid state drives (SSD), and NVMe storage. Instead of opening dozens of Amazon tabs and doing spreadsheet math, you get every listing in one sortable hard drive price table — normalized to price per terabyte ($/TB) and price per gigabyte ($/GB) so a 4 TB drive and an 18 TB drive are easy to compare on equal footing.
Whether you are building a home NAS, upgrading a gaming PC, stocking a homelab, or just trying to answer "how much is a terabyte?" — this is the website that shows prices for hard drives and solid state drives alongside the specs that actually matter. We track internal HDDs, SSDs, NVMe drives, NAS-class disks, and related storage categories so you can run a real disk price comparison without guessing.
Unlike a simple deal feed, Disk Prices is a full-parameter storage database. Every row is a real Amazon listing with pricing, capacity, interface, form factor, warranty, and dozens of optional technical fields you can surface when you need them. Sort by $/TB to find the best HDD price or SSD price in seconds, then drill into RPM, CMR/SMR recording type, IOPS, or TBW before you buy.
We are launching with Amazon United States first, with more regions coming soon — including Amazon UK, Germany, France, Canada, Italy, Spain, and Japan. Each marketplace will show local pricing, currency, and language so you can compare disk drive and hard drive deals where you actually shop.
What You Can Do With This Disk Price Comparison Tool
Most price trackers show a product name and a dollar amount. This tool gives you a full workspace for comparing every storage listing on equal footing.
01 · Comparison table
Full-parameter comparison table
See every hard disk drive (HDD), solid state drive (SSD), and NVMe listing in a single view. This is not a top-ten list — it is a comprehensive hard drive price table where no spec gets left behind. Compare disk prices across brands, capacities, and form factors without switching between product pages.
02 · Columns
Customizable columns
Storage shoppers care about different things. A NAS builder wants CMR vs SMR and warranty length; a gamer wants NVMe sequential read speeds and IOPS; an IT buyer wants MTBF and TBW. Pick only the columns you care about and build a personal hard drive cost worksheet that fits your use case.
03 · Search
Live search
Type any keyword — a brand name, model number, interface like SATA or SAS, rotational speed, or even a partial product title — and the table filters in real time. No page reloads, no waiting. Find the exact disk drive you need among hundreds of listings instantly.
04 · Filters
Advanced parameter filters
Go beyond search with structured filters. Set a maximum $/TB, a minimum capacity, a media type (HDD, SSD, or NVMe), a recording type (CMR or SMR), a form factor, a price range, or a seller rating threshold. Stack conditions to narrow thousands of listings down to the handful worth buying.
05 · Brands
Brand filter
Compare HDD prices and SSD prices across Seagate, Western Digital, Samsung, Crucial, SK hynix, Toshiba, and every other brand in the database. Brand filtering works alongside every other filter so you can see whether your preferred manufacturer still offers the best price per TB at the capacity you need.
06 · Value metrics
Price per TB and price per GB
Raw price tags are misleading. A $90 2 TB SSD looks cheaper than a $200 4 TB HDD — but the HDD delivers far better value per gigabyte. We calculate price per TB and price per GB for every listing so you can compare hard drive sizes fairly, whether you are buying a 500 GB boot drive or a 20 TB archive disk.
07 · Sharing
Saved groups and share links
Found a great set of drives? Save your filtered results or hand-picked shortlist to a named group. Share the group with a friend, colleague, or forum thread in one click — perfect when someone asks "which hard drive should I buy for my NAS?" and you want to send them a curated answer, not a vague recommendation.
08 · Community
Community editing
Spotted a wrong RPM, a missing CMR label, or an outdated price? Edit any field directly in the table. Your changes appear in your personal view immediately — no approval queue for your own workspace. When your edit is reviewed and approved, it is shared with the entire community so everyone benefits from more accurate disk prices data.
Why our Disk Prices Tools Stands Out
Most price trackers show you a product name and a dollar amount. Disk Prices shows you the full picture. We ingest every attribute Amazon publishes for a storage listing — capacity, interface, form factor, RPM, read/write speeds, NAND type, warranty, and more — and organize them into a consistent hard drive price table you can sort, filter, and customize.
Accuracy matters when you are spending hundreds of dollars on a drive that will hold years of irreplaceable data. Our product library grows continuously with new SKUs, prices are monitored on an ongoing basis, and critical fields like capacity, media type, and CMR/SMR recording type are manually verified. You get automated breadth with human-checked quality on the specs that trip people up most.
The table is both a public library and your private workspace. Think of it as a community-maintained spreadsheet for disk drive and hard drive shopping — except you do not have to maintain the spreadsheet yourself. Edit what you see, save what you need, and contribute corrections that help the next person running a disk price comparison.
From a budget SATA SSD for an old laptop to an 20 TB enterprise hard disk drive for a RAID array, from portable USB enclosures to NVMe drives pushing 7 GB/s — one tool covers the full range of hard drive sizes and storage categories. Whether you care about absolute lowest price or lowest price per TB, Disk Prices gives you both views without leaving the page.
Every Hard Drive Parameter We Collect
If Amazon lists it, we capture it. Not every product has every field, but our database is designed to hold the complete set of storage specifications so you never have to wonder what is missing. Parameters are grouped below by category. Default columns appear automatically; optional columns are available through the column picker.
01 · Pricing
Pricing and value
Price (USD), price per TB ($/TB), and derived price per GB ($/GB) — the three numbers that answer "what does storage actually cost?" We also track condition (new, used, renewed, refurbished) and seller rating so you can weigh a lower HDD price against third-party seller risk.
02 · Identity
Identity and catalog
Brand, manufacturer, model, model number, manufacturer part number (MPN), product title, ASIN, UPC, and GTIN. These fields tie each row to a specific SKU so you can cross-reference model numbers, verify you are buying the right revision, and search by exact part number.
03 · Capacity
Capacity and classification
Digital storage capacity across all common hard drive sizes — from 128 GB SSDs to 24 TB hard disk drives. Media type covers HDD, SSD, NVMe, NAS, and tape. Recording type flags conventional magnetic recording (CMR) versus shingled magnetic recording (SMR), a critical distinction for RAID and NAS workloads.
04 · Form factor
Form factor and connectivity
Form factor (3.5-inch, 2.5-inch, M.2, and more), hard disk interface (SATA, SAS, U.2), connectivity technology, hardware interface, hardware connectivity, and installation type. These fields tell you whether a drive will physically fit and electrically connect in your system.
05 · HDD
HDD performance
Rotational speed (RPM), cache size, and data transfer rate. For mechanical hard drives, RPM and cache largely determine throughput and latency in sequential workloads — essential when comparing 5400 RPM archive drives against 7200 RPM performance disks.
06 · SSD/NVMe
SSD and NVMe performance
Sequential read and write, random read and write, IOPS (input/output operations per second), read speed, write speed, media speed, and data transfer rate. These specs separate a budget SATA SSD from a high-end NVMe drive and help you judge real-world performance beyond the price tag.
07 · Endurance
Endurance and reliability
Terabytes written (TBW), drive writes per day (DWPD), mean time between failures (MTBF), hard disk service life, and warranty description. For SSDs, TBW and DWPD tell you how much data the drive can endure over its lifetime. For enterprise HDDs, MTBF and warranty length matter when drives run 24/7.
08 · NAND
NAND and controller (SSD)
Flash memory type, NAND flash type, controller type, memory type, and SSD series. These fields reveal what is inside the drive — TLC versus QLC NAND, DRAM cache presence, and controller generation — which affects both performance consistency and long-term value.
09 · Enterprise
Enterprise and niche
RAID level, number of bays, tape type, native capacity, compressed capacity, compatible devices, and specific use cases. These cover NAS enclosures, tape backup systems, and specialized storage products that do not fit a simple HDD-or-SSD binary.
How to Use This Disk Drive Price Table
Start with the default sort: price per TB ($/TB). This immediately answers the most common question — "how much is a terabyte?" — across every capacity and media type. A $130 8 TB HDD and a $250 18 TB HDD might look far apart on raw price, but their $/TB values tell you which is the better deal per unit of storage.
Use the search box for quick filtering. Type a brand ("Seagate"), an interface ("NVMe"), a speed class ("7200"), a product line ("IronWolf"), or any term that appears in the listing data. The table updates as you type, so you can iteratively narrow results without building a complex filter first.
Add structured filters for precision. Example: media type equals HDD, recording type equals CMR, capacity greater than or equal to 8 TB, and $/TB less than $15. This combination is a typical NAS builder query — and it takes seconds to set up. Combine brand filter, condition filter, and seller rating to control exactly which listings appear.
Customize your columns for the decision you are making. Building a ZFS pool? Add CMR/SMR, warranty, and MTBF. Shopping for a laptop SSD? Add sequential read, IOPS, and TBW. Comparing used disk prices? Show condition and seller rating alongside $/GB. Your column set is saved in your browser so the table remembers your preferences.
Save and share when you are done. Create a named group from your current filter results or from manually selected rows. Send the share link to a friend who is building a PC, post it in a forum, or keep it as a personal shortlist to monitor over time. Groups make it easy to revisit a set of drives without reconstructing your filters every visit.
Pro tip: sort by raw price when you want the cheapest drive at a fixed capacity; sort by $/TB when you want the best value across hard drive sizes; sort by $/GB when comparing smaller SSDs below 2 TB. For used and renewed listings, always filter by condition first, then compare $/TB against new drives to see if the savings justify the risk.
About the Data
Product data is collected from Amazon United States listings for internal and external storage devices, including hard disk drives (HDD), solid state drives (SSD), NVMe drives, NAS-class disks, and related categories.

Frequently Asked Questions
Common questions about comparing disk prices, drive specs, and how this tool works.
How much is a terabyte of storage?
It depends on the drive type and current deals. As a rough guide, check the $/TB column in our table — it shows the effective cost of one terabyte for every listing. HDDs typically offer the lowest price per TB ($10–$20/TB is common on sale), while NVMe SSDs cost more per terabyte but deliver far higher speed. Sort by $/TB ascending to see today's cheapest terabyte of storage.
How much is a petabyte?
A petabyte is 1,000 terabytes. No consumer drive holds a petabyte, but you can estimate the cost by multiplying the best enterprise $/TB you find in our table by 1,000. For example, if the lowest enterprise HDD price is $12/TB, one petabyte of raw drive capacity would cost roughly $12,000 in disks alone — before enclosures, RAID overhead, and power. Use our table to find current enterprise $/TB and do the math.
What is the difference between HDD price and SSD price per TB?
Hard disk drives (HDD) use spinning platters and historically offer the lowest price per TB — ideal for bulk storage, backups, and NAS arrays. Solid state drives (SSD) use flash memory and cost more per terabyte, but deliver faster access times, lower power draw, and no moving parts. NVMe SSDs are the fastest category and usually the most expensive per TB. Our table lets you filter by media type and compare $/TB side by side.
What is CMR vs SMR and why does it matter?
Conventional magnetic recording (CMR) writes data to fixed tracks — the standard for NAS, RAID, and heavy random-write workloads. Shingled magnetic recording (SMR) overlaps tracks to pack more data onto fewer platters, lowering cost but slowing random writes. SMR drives work fine for sequential backups but can cause problems in ZFS, RAID, or busy NAS pools. Our recording type column flags CMR and SMR so you can avoid surprises.
How do I compare different hard drive sizes fairly?
Use price per TB ($/TB) or price per GB ($/GB) instead of raw price. A 2 TB drive at $60 ($30/TB) is worse value than a 4 TB drive at $80 ($20/TB) even though the 4 TB drive costs more upfront. Our table calculates these metrics automatically and sorts by $/TB by default, so comparing 1 TB, 4 TB, 8 TB, and 18 TB drives takes one click.
Can I use this table to find used disk prices?
Yes. Filter by condition to show used, renewed, or refurbished listings alongside new drives. Compare the $/TB of used drives against new ones to see if the discount is worth it. We also show seller rating so you can factor third-party seller reliability into your decision.
How does community editing work?
Click any editable cell in the table to correct a value — a wrong RPM, a missing warranty, an outdated price. Your edit appears immediately in your personal view. When the change is reviewed and approved, it becomes visible to all users. This keeps the hard drive price table accurate without waiting for a central team to fix every listing.
Which Amazon regions are supported?
We are launching with Amazon United States first. Additional Amazon marketplaces — including UK, Germany, France, Canada, Italy, Spain, and Japan — are coming soon. Each region will display local pricing, currency, and language so you can compare disk prices where you shop.
