Would I buy it?
At the £1,399 shown in Amazon’s price history, I’d wait unless I needed 8TB of fast storage in a single slot. That works out at £174.88 per TB. At the lowest price Amazon showed in the previous 30 days, the same drive cost £148.75 per TB. Buying at the top of that range meant paying £209 more for exactly the same storage.
This is a review of the specifications and UK price history, rather than a hands-on speed test. If you’re shopping for “PC memory”, check what is running short: an SSD gives you room for games, photos and files. It won’t increase your computer’s RAM.
How much did the Amazon UK price rise?
In the one-year Amazon Rufus chart captured on 4 November 2026, the line starts close to £545 around the previous November. It moves up in steps, spends part of the year near £973, then finishes at £1,399. That’s roughly £850 more, or around two and a half times the starting price. The first figure is an estimate read from the chart.
The shorter comparison is more precise: Rufus gives a 30-day range of £1,190 to £1,399. The final price was the high, about 17.6% above the low. The chart tracks each week’s lowest featured offer and excludes delivery. It doesn’t tell us which seller set each price or why it changed.

Why does this 8TB SSD cost so much?
The appeal is fitting an entire large working library onto one small drive. Eight terabytes requires more flash storage than a 2TB drive, and this is a performance model: SanDisk lists the 8TB SN850X as a PCIe 4.0 x4 NVMe drive with sequential reads up to 7,200 MB/s. That figure describes ideal large reads, not how fast every game will load. Those features explain what you’re buying, but they don’t explain a £209 swing for an unchanged model.
How to buy the storage you actually need
- Check your bottleneck. If your 1TB drive is full but half of it is old photos, moving those to cheaper storage may save more than replacing your main drive. Keep another copy of irreplaceable files.
- Count your slots. Check your motherboard or laptop manual for M.2 2280 NVMe support, clearance and cooling. The linked model is the version without a built-in heatsink. Don’t assume an M.2 slot that only supports SATA will work.
- Put a ceiling on the price. At £1,399 for 8TB, two 4TB drives would cost less if each came in under £699.50 delivered. That comparison only helps if you have two suitable slots. If 4TB covers your needs on its own, compare the total spend first.
- Match speed to use. For large active video projects or a big games library in a single-slot PC, the 8TB drive makes more sense. For occasional backups, compare an external hard drive before paying for internal SSD speed.
My buying rule: If the upgrade can wait, I’d set a price alert around £1,190 for this exact 8TB variant and compare other UK sellers. That was a recent low in the supplied chart, not a prediction that it will return.
