Customer Reviews

Great deals to be had

Got 4x18Tb disks on a really good deal. Disks arrived very well packed (and earlier than expected) with plenty of impact absorbing packaging. They were inside sealed static bags. Checking warranty on the Seagate website, which recognised them but said the vendor has warranty (which is what Robert Electronics mentions in large font anyway).

Spent a week testing the disks before using them in the NAS and as far as I could tell, they seem to be all fine. With a saving of £80 per drive (vs what I wanted to get), can't argue with that. Very happy with the drives.

Cheap and Cheerful

Took the plunge on buying these as reviews generally seemed pretty good here and elsewhere on the internet and I was not dissapointed; yes it takes like 2 weeks for them to arrive but I paid no extra fees for this even though they were shipped from Asia. Both work within my setup for unRaid and after running a preclear/SMART test they both came back clear, one of them occasionally makes some reasonably loud noise but it's not that often. Packaged well and the cheapest around if you need some 18TB these are the ones to get!


Order one!
100% will order more when required.
Best price too

Cheap, genuine, well packaged and delivered within the agreed timeframe

Much cheaper than anyone else delivering to the UK.
No additional fees for delivery, all taxes and duties pre-paid by the seller.
Very well packaged.

It will take a while for your order to ship and a few days after that for it to be trackable. All as described in the FAQs and all within the promised timeframe at time of ordering.

OEM drives, so I will have to go back to Robert Electronics for service if needed, but hopefully we won't have to worry about that.

Overall, I'm very happy!
