On Amazon, today only, they have some big discounts on M2 SSD Gen4 storage. Including Sony PS5 certified M2 drives with heatsink.
I've ordered a Samsung 980 Pro M2 2TB with Heatsink for £163. That's 35% off the £253 RRP.
They had a lot of makes in all sizes including 1TB, 2TB and 4TB. The v4TB are still a bit expensive yet. Even with a fixing they were close to £500.
They also have a "WD_BLACK SN850X 2TB M.2 2280 PCIe Gen4 NVMe Gaming SSD with Heatsink up to 7300 MB/s read speed" for £179, reduced from £327, so 45% discount, which I nearly got before spotting the Samsung (which is the one I was originally going to buy anyway before this sale).
