    Cracking price, better drive than the ADATA S70 Blade and Addlink A95 drives I rave on about and for less money.

    Here's a cheap but good heatsink if you need one -

    Brilliant price. If it was nearer payday I would have taken two.

    Still £64 per terabyte, complete rip off, and you'll need a heatsink for it.

    Also a terrible speed on that, yeah...

    I missed the overclockers deal on this at £252.98 last month, given the size and speed this is a great price IMO

    I picked one up, SN850X. Unboxed. Brand new for £175 last week from eBay. Checked TBW & POC. POC was 3 and zero bytes written. Installed in PS5 and has been working fine.

    There's also 10% cashback via Quidco
    rufioh's avatar
    Are you a Quidco subscriber? 7.5% with my standard account, which is still very high.

    Why is it expired it's still working for me.
    mrpipster's avatar

    That's why it's been expired

    I guess the £50 off replaces the free delivery offer, which is strange but only adds £6.09 to the cost for me.
  13. driver8's avatar
    Good price, but a pity that 2x2TB is still generally quite a bit cheaper per TB.
    As well as quidco, I think there's a voucher on signup (but unsure if it applies here).

    Tell me about it, been waiting for a 6000+ r/w spec 4tb to get near £250 for the 2nd nvme slot in my laptop.

    Didn't want to buy 2x2tb as my OS drive is gen4 SK Hynix, albeit only 512gb but that is ample for an OS only drive.

    I have an Orico nvme enclosure for my now replaced gen 3 2tb drive.

    Showing as £263.08 in basket now. Looks like free shipping was fixed but now the price is higher then what it was with paid shipping. (edited)

    Begging for an 8tb Raid 0 with 14,000MB/s read & write.
  18. Munkle's avatar
    If you're a student (or teacher) you can get 15% off the 2TB version which makes that one £111.35

    I've tried this and it's saying my discount code is not valid! (I signed up and received a code through my institution e-mail via the Youth Discount portal).
