How to read PCPriceWatch

What does $/TB mean?

Price per terabyte: the price divided by the drive’s capacity. It’s the fairest way to compare drives of different sizes. A 20 TB drive at $300 ($15/TB) is better value than a 4 TB drive at $80 ($20/TB).

Prices include shipping when the seller states it. The table is sorted by $/TB, cheapest first, unless you choose another order.

What do the green and grey trend lines mean?

Green: cheaper now than 30 days agoGrey: the same or higher

Each small graph shows the lowest Buy It Now price for that drive on each of the last 30 days.

A green line means today’s price is lower than it was 30 days ago. A grey line means it’s higher or unchanged. The line can rise and fall in between; only the first and last day decide the colour.

Hover over (or tap) a graph to see the low, the high and the change. Click it to open the drive’s full price history.

What does “↓ X% below avg” mean?

↓ 13% below avg

The drive’s lowest Buy It Now price today is at least 10% below its own average over the last 30 days.

It needs at least 3 days of history, so new listings don’t get a badge straight away. All of these drives are listed on the Price drops page, biggest drop first.

What does “Featured” mean?

Featured

Featured drives are picked by PCPriceWatch and always stay at the top of the list, whatever order you choose.

What do New, Used and Refurbished mean?

They come from the seller’s own listing. Refurbished includes “renewed”, “recertified” and seller-refurbished drives. The same drive can appear twice, for example once new and once refurbished, because their prices differ a lot.

Why are eBay and Amazon shown separately?

Use the eBay / Amazon switch above the list to choose a store. Each view shows only that store’s prices, so you’re always comparing like with like. Your choice is remembered.

Are eBay prices sold prices?

No. They’re the prices of live Buy It Now (fixed-price) listings: what you could buy the drive for right now. Auctions and sold prices aren’t included.

Why doesn’t the Amazon view have trend graphs or price drops?

Amazon’s rules for sites like this don’t allow showing Amazon price history or price-drop alerts. The Amazon view shows current Amazon prices only.

Why does a button say “Search” instead of a price?

That store has no current listing we could match to this drive, so the button opens a search for it on that store instead.

What do US and CA mean?

US shows Amazon.com and eBay.com prices in US dollars. CA shows Amazon.ca and eBay.ca prices in Canadian dollars, from listings that ship to Canada. Prices are never converted between currencies.

How often are prices updated?

Prices are refreshed automatically, about every 24 hours. The time of the last update is shown under each page title. Prices can change at any time, and the store’s price at checkout is the one that applies.

How do price alerts work?

On any drive’s page, enter a target price and your email. We send one email to confirm, then email you when the lowest Buy It Now price reaches your target. You’re emailed again only if it drops another 5%.

Every email has a one-click unsubscribe, and your address is never shared.

Why is a drive missing, or matched to the wrong listing?

Listings are matched to drives from their titles, using the brand and model number. Lots, bundles, enclosures and for-parts listings are left out on purpose. If a match looks wrong, it will usually be fixed after the next update.

Is there a phone version?

Yes. Phones get a layout made for small screens automatically. Use “Desktop view” at the bottom of the page to switch, and “Mobile view” in the sidebar to switch back.

Do you track visitors?

Each page view is recorded with your IP address, the approximate city it maps to and your internet provider's name, so we can see where visitors come from and filter out bots. The lookup happens on our own server, nothing is shared or sold, and full IP addresses are shortened after 365 days. There are no advertising trackers.

Does PCPriceWatch earn money from links?

Yes. As an Amazon Associate I earn from qualifying purchases, and eBay links are eBay Partner Network links. You pay the same price either way.
