Amazon Storage & Disk Prices in the UK

Written by Lucky, who has spent over a decade running home-lab NAS builds and still sources every drive by price per TB before buying.

Compare Amazon Storage & Disk Prices in the UK by Cost per TB

Divide the price by the capacity in terabytes to get one price per TB figure, then line that number up across Condition, technology and form factor. A £45 drive with 4TB works out at £11.25 per TB. A £140 SSD with 2TB works out at £70 per TB. Once every listing is expressed the same way, a hard drive, an SSD and a used enterprise drive all become directly comparable — no unit conversions, no guesswork.

That single figure is the backbone of every filter below, and how the UK market handles pricing and condition grading has a few quirks worth knowing before you rely on it.

What "Price per TB" and "Price per GB" Actually Mean

Price per TB is the listed price divided by the drive's rated capacity in terabytes. Price per GB is the same sum at a smaller scale, and it tends to read more naturally for anything under roughly 500GB — memory cards, flash drives, small SSDs. Switching between the two doesn't change the underlying value, only where the decimal point sits.

A UK-Specific Detail Worth Knowing: VAT and Marketplace Sellers

Listed prices on Amazon.co.uk already include 20% VAT, unlike some regions where tax is added separately at checkout — so the figure you see is the figure you pay, and it's the correct number to use for your price-per-TB comparison without any adjustment.

A large share of storage listings on Amazon.co.uk come from third-party Marketplace sellers rather than Amazon directly. That doesn't change the price-per-TB maths, but it does mean warranty terms, dispatch times and return handling can vary by seller — worth a quick check before assuming two identically priced listings offer identical protection.

Condition: New vs. Used, and What UK Consumer Law Actually Covers

A New drive carries the full manufacturer warranty and no prior power-on hours, which is reflected in a higher price per TB.

A Used drive has already logged hours elsewhere — very often pulled from a data centre refresh cycle rather than worn out, sold on at a lower price per TB in exchange for a shorter or absent warranty. Under the Consumer Rights Act 2015, goods bought from a UK trader (including Marketplace sellers based in the UK) still need to be "as described" and of satisfactory quality, with a short window to reject faulty goods outright — worth knowing when a used-drive listing looks unusually vague about condition.

Rotational vs. Solid State: Choosing the Technology

Rotational drives (HDDs) typically run at a markedly lower price per TB than solid state, which keeps them the default for bulk backups, media libraries and NAS arrays where raw capacity outweighs speed.

Solid State drives cost more per TB but read and write with no moving parts — the right call for a boot drive, an active project folder, or a laptop that needs to survive being knocked about.

Independent, large-scale reliability figures — for example, Backblaze's ongoing hard drive failure-rate reports — are a useful reference point before deciding how much to trust a used mechanical drive against paying more for solid state.

Internal vs. External, 3.5" vs. 2.5"

Internal 3.5" drives are the standard for desktops and NAS enclosures, carrying the largest capacities in the range at a price per TB that typically runs well below other form factors here.

Internal 2.5" drives fit laptops and small-form-factor builds, giving up some capacity headroom for a smaller footprint.

External 3.5" and External 2.5" drives are the same mechanisms housed in a USB enclosure — expect a modest premium over the equivalent bare internal drive for the housing and cable.

Internal Hybrid drives pair a small flash cache with mechanical platters, aiming for HDD-like capacity with some of the responsiveness of solid state — a middle ground, priced accordingly.

Internal SAS drives are built for servers and storage arrays: dual-port connections and higher duty-cycle ratings aimed at business buyers running an HBA controller, not a typical desktop upgrade.

Solid State Form Factors: SATA, NVMe, M.2 and U.2/U.3

External SSD and Internal SSD use the same flash — the difference is purely the enclosure and interface, portable USB versus a direct motherboard connection.

M.2 SATA drives use the compact M.2 connector but still run over the older SATA protocol, capping speed similarly to a 2.5" SATA SSD.

M.2 NVMe drives use the same connector but talk directly over PCIe, which is where the real speed increase happens — the standard choice for a current laptop or desktop boot drive.

U.2/U.3 drives look like a 2.5" bay drive but carry an NVMe connection built for servers — hot-swappable, higher endurance, priced for data centre and workstation use.

Volatile Memory Filters: DDR5 vs. DDR4, UDIMM vs. SODIMM vs. RDIMM

DDR5 is the newer memory generation and typically carries a higher price per GB than the now-mature DDR4 market.

UDIMM is the standard unbuffered module for desktops. SODIMM is the compact version for laptops and small-form-factor PCs. RDIMM adds a register buffer between memory and controller, which is what lets servers run large numbers of high-capacity modules reliably.

Match the DIMM type to the system first, then compare price per GB within that type — mixing DDR generations isn't a pricing decision, it's a compatibility one.

Removable and Flash Storage

microSD Flash and SD Flash cover phones, cameras and handheld devices, with SD generally holding a capacity and speed edge over its smaller sibling.

Compact Flash and CFast Flash are older professional camera and industrial formats, still in active use in equipment built around them.

CFexpress Flash is the current high-speed standard for professional video and photography, sitting well above CF and CFast in both throughput and price per GB.

USB Flash remains the simplest way to move files between systems, with price per GB dropping sharply as capacity increases.

Optical Media: BD-RE, BD-R, DVD-RW/DVD-R, CD-RW/CD-R

Optical discs are a small slice of the current market, but they still serve archival storage well — a format that doesn't depend on a spinning motor or a flash cell holding its charge.

BD-R, DVD-R and CD-R are write-once, suited to a permanent archive copy. BD-RE, DVD-RW and CD-RW are rewritable, better for a backup disc you plan to overwrite on a schedule. Blu-ray formats hold considerably more data per disc than DVD or CD, which accounts for most of the price-per-GB gap between them.

Tape: LTO-3 Through LTO-9 for Backup and Compliance

LTO tape is built for one job: storing large volumes of data offline at a price per TB that runs considerably below every other format in this catalogue. Each generation from LTO-3 to LTO-9 roughly doubles the native capacity of the one before it, while staying read-compatible with the previous generation and write-compatible one generation back.

Many UK organisations lean on LTO specifically to meet data retention requirements under UK GDPR — an offline, air-gapped copy is straightforward to account for during an audit in a way that live cloud storage sometimes isn't.

When a Drive Reaches the End of Its Life

An old hard drive or SSD doesn't belong in general household rubbish — it counts as electrical waste, and UK retailers and councils are required to provide a route for proper recycling.

Before handing a drive over for recycling, remove any memory cards and make sure the data on it has been dealt with. Recycle Your Electricals, the UK-wide campaign backed by producer-funded recycling schemes, has a postcode locator for the nearest drop-off point.
