Q: Does this come with the required cables to plug into my PC and how will I check if the cables are compatible with my PC?
Answer by Website User on 1st August 2018
No, it will not come with the required cable. You need to purchase a SATA cable separately and you would need to check if your motherboard has a SATA connector.

The hard drives arrived the next day after I ordered them, and were very well packed, the price was a little under the competitors, and so far have proved completely reliable. They are now installed in my HP Server as part of a 4 drive redundant setup. I actually bought 4 of them.

Seems like a good drive so far with a decent amount of storage

Probably one of the most boring products to look at, but then we don't buy HDDs to look at. I have to say that this new Seagate drive is surprisingly slimmer than the previous HDD I've had to replace, so that should aid air circulation inside a NAS. Delivery from CCL was very prompt, with the HDD itself extremely packaged, bearing in mind it's internal mechanism. No doubt at some point in the future I'll probably have to replace another of the older HDDs in the NAS, but at least I know exactly which one I'll go for.

Fantastic HDD well fast

Does what it says on the tin, arrived in good timing and is not broken. Couldnt ask for more.

Love this product, i bought this because i got very tired of having to uninstall a game then install another one due to having no space. It took a little while to setup but it seemed easy, i'm now able to have more games added from my games library. Thanks a bunch! Will be recommending CCL for PC component needs.

Lots of storage space for little cost. Drive is fairly quiet and transfer speeds ok.

Good value, used in my NAS which works as a Steam Cache and backup server.

Very quick hard drive with fairly quick read/write speeds of 160MB/s. Also extremely quite for a spinning disk, can barely be heard when operating.

Sensible price for the amount of storage, securely packaged and with extremely prompt delivery to boot. What's not to like?

Nothing to say about the drive- does what it says on the tin! Used as replacement for a failed drive in an Apple time machine. Service was exemplary, arrived in less than 24 hours exactly as promised. Definitely will use again.

General use hard drive from Seagate. Good price for the capacity. Plugged into motherboard SATA connectors, switched on and it was recognised instantly, no need to do any more. I've been working it hard over the last month and it's still running nice and quiet with no issues.

Great service, website easy to use clear as to deliver etc. goods arrived when they said they would packed really well. Good price and great service.

I have given 5 stars for all ratings on the basis of previous Seagate drives. As far as this one is concerned I can safely say, so far, so good.

Excellent disk fast and quick service.

Not died in about 5 mouths, still going strong as my primary files drive. Full load transfer speeds are okay for a spinning rust drive, response time again not bad.

It's a 4TB HDD that is now installed and working. Longevity???? An unknown. I have used Seagate drives on previous occasions and will probably do so again.

good product


October 2019

Running for approximately one month and all is great


September 2019

Its a hard drive at a good price what more can I say


September 2019

The Disk is a bit slow, but its what you can expect from a 5400 RPM HDD. I use it to store my games library, while my OS is on a smaller NVME M.2 SSD. Boot times for the games are adequate, and there is plenty of disk space available in 4TB. If you need a large storage drive soon, I would recommend this. However, the price of SSDs and HDDs have been falling for years by a significant margin - if you can wait, I would. Two years ago the price was the same for half the storage, and I expect this trend to continue.


September 2019

Excellent for storage. I use these in my Unraid server and they work a charm. Quiet and no vibrations.


September 2019

Great product at a fantastic price. Also very speedy delivery even when used free P&P option


July 2019

Big of a pain formatting it. had to search internet for solution. 4tb internal drives do not format on MBR shame support were not helpful (WEB live chat) Almost returned for refund due to this.


July 2019

Replaced a 1 tb that was just not big enough now and it out performs it in every way. Access speed, read/ write performance and noise all way better than I expected. Would definitely by another soon
