4TB SSD prices in the UK
Published: Updated:
4TB SSDs at UK retailers, priced in pounds with VAT included and ranked by cost per terabyte.
UK prices coming soon
We have not imported any UK prices yet, so there is nothing to rank. When the first import runs, this list shows new, in-stock offers in pounds, VAT included, cheapest per TB first, with the time each price was recorded. We never fill gaps with estimates.
What to check before you buy
Why 4TB. At 4TB, endurance ratings and DRAM cache sizes are usually higher than at smaller capacities of the same model. Two examples from manufacturer datasheets:
| Model, 4TB | Interface | Rated endurance | DRAM cache |
|---|---|---|---|
| Samsung 870 EVO | SATA 6 Gb/s, 2.5-inch | 2,400 TBW | 4GB LPDDR4 |
| WD_BLACK SN850X | PCIe 4.0 x4, M.2 2280 | 2,400 TBW | not stated |
Sources: Samsung 870 EVO datasheet; Sandisk WD_BLACK SN850X.
Price per TB, not price. A 4TB drive costs more than a 2TB drive, but may cost less per TB. The table is sorted by price per TB for that reason.
Single- or double-sided. Some high-capacity M.2 drives carry chips on both sides of the board, which can matter in thin laptops. Check the drive’s height in its datasheet against your device.
For a PS5. Sony supports M.2 drives from 250GB to 8TB, so 4TB is within range. The drive must be PCIe Gen4 x4 M.2 NVMe and needs a cooling structure such as a heatsink or heat transfer sheet (Sony).
About UK prices
- VAT included. Prices are in pounds sterling and include VAT, the way UK retailers show them to consumers. Delivery charges are not included.
- Planned sources. We plan to track UK retailers such as Scan and Overclockers UK; Ebuyer is under review. None is connected yet, and no retailer pays to be listed.
- Tracked separately. UK prices are collected from UK shops — they are not US prices converted from dollars, so the cheapest drive per TB can differ between the two lists.
- Time stamps are shown in UK time. Full rules: methodology.
