UK’s Most Awarded PC Manufacturer

As one of the top manufacturers of UK gaming computers, Chillblast is no stranger to winning awards. In fact, we’ve taken first place in the PC Pro Excellence Awards (previously known as the ‘Reliability and Service Awards’) a record ten times. We’ve also been named ‘Desktop Retailer of the Year’ by PC Advisor for four consecutive years.

But doesn’t mean competition wasn’t intense. Chillblast was up against some of the biggest names in the industry, including Apple, Dell, PC Specialist and Scan. In the most recent round of awards (2018), Chillblast took first place with an astounding 97% customer satisfaction rating.

The secret to our consistently high rankings and stellar customer-satisfaction ratings is simple. You see, from the time that you enquire about a Chillblast gaming computer to the moment it’s delivered, you’ll be dealing with representatives who really understand your needs. That’s because Chillblast only employs PC experts – even for customer service positions.

When you call in, you’ll rarely have to wait before speaking to a representative. And we also check our email regularly in order to offer prompt call-backs. The result is a seamless service model in which you’re kept in the loop and confident that the representative you’re dealing with understands your technical needs and expectations.

5 Year Warranty (Terms & Conditions Apply)

Given the fact that we manufacturer some of the best gaming desktops currently available, it should come as no surprise that we’re willing to stand beside our craftsmanship. Chillblast’s industry-leading warranty offers two phases of protection.

Our standard warranty begins with a two-year collect-and-return package, during which time we offer local-rate telephone support and unlimited repairs. We’ll both collect and return your custom pc at no charge. This applies to all models – whether you purchased a cheap gaming desktop or an ultra-high-spec custom built PC.

But we don’t stop there. Chillblast also offers an additional three years of warranty coverage after your collect-and-return package expires. During those three years, we’ll continue to provide labour-only support.

We believe this is one of the best warranties available from any custom PC builder in the UK. And if you’re looking for additional peace of mind, we also offer a 3 Year Gold Collect-and-Return Warranty as a potential add-on for desktop PCs specifically.

Buy a gaming desktop or custom build PC from Chillblast, and the benefits continue long after that initial five-year period. Even out of warranty, Chillblast is delighted to offer customers exclusive upgrades and repair services with discounted parts and subsidised collection, delivery and labour charges.

Seagate Firecuda 520 PCIe Gen 4 2TB SSD Review


Seagate – a Slumbering Beast Awoken

After a very late arrival to the SSD party, Seagate has been releasing new products at a furious rate. Its initial 2.5” offerings were competitive with industry stalwarts Samsung and have been priced more competitively, whilst the firm’s Barracuda and Firecuda 510 M.2 drives once again compare pretty favourably to the Samsung 970 EVO series that have been enthusiast favourites for so long. With this, the Firecuda 520 M.2 drive, Seagate is one of the first manufacturers to take advantage of the new PCI Express 4 technology available on the latest AMD Ryzen chipsets.

What is PCIe 4?

PCIe 4.0 offers double the peak theoretical bandwidth of the previous 3.0 specification and is featured in AMD’s X570 (Ryzen) and TRX40 (Threadripper) chipsets. At time of writing Intel’s most advanced chipsets – the Z390 and positively ancient HEDT X299 – remain limited to PCIe 3.0. Does this really matter? Well, yes it does.

Current flagship M.2 SSD drives are so fast that the 3500-3600 MB/s they max out at when reading and writing is because of PCIe bus saturation rather than a limitation of the chipsets themselves. Unfortunately, plugging a PCIe 3.0 drive into a PCIe 4.0 slot doesn’t magic up any extra bandwidth; you need support at both a chipset and an SSD controller level.

Enter the Seagate Firecuda 520

Seagate’s FireCuda 520 series is one of only a few PCIe 4 drives to hit the market, and the first from a storage-focussed manufacturer. Like other PCIe 4 drives we’ve seen from Gigabyte and Corsair, Seagate’s new flagship uses the Phison E16 controller. The headline quoted figures are mighty, with a quoted sequential read of 5,000MB/s and a sequential write of 4,400MB/s. IOPS are rated at up to 760,000 and there is a 3600 TBW endurance rating on this 2TB model – the largest available. How does that compare to the Samsung 970 EVO, long a Chillblast favourite? Very favourably is the answer. Samsung claims sequential maximum throughput of 3400MB/s and 2500MB/s for Read and Write respectively, while the IOPS rating of Samsung’s largest NVMe is 500K. Endurance-wise Seagate has really taken its rival to the sword – the 970 EVO is rated to only a third of the Firecuda's 3600TBW rating with just 1200 TBW.


All of Seagate's drives benefit from the free Seatools software that allows you to monitor the health status of your drive, perform a secure erase, update the firmware and clone your data to a new drive. 


In Crystal Disk Mark the Seagate Firecuda 520 is the first M.2 drive we’ve seen to bust through the 5GB/s barrier. Sequential write speed was no less impressive, with the drive recording an epic 4.3GB/s. That’s nearly a full GB/s quicker than Samsung’s market leader.  Things are a lot closer when we look at small file random read and write performance, but the Firecuda 520 is still meaningfully faster than the 970 EVO Plus.

Moving onto real-world gaming tests we see that the Firecuda 520 doesn’t really load environments any faster than other M.2 drives. That’s due to a mixture of factors. Firstly, game levels normally consist of lots of small reads rather than large sequential data sets, and secondly because game level loading is becoming increasingly CPU bound due to data decompression.

PCMark 8 has long been our go-to benchmark for analysing the real-world performance of a drive because it closely replicates workloads actual applications produce. In this test Samsung drives have traditionally held a commanding lead over the competition, but despite getting close, they were unable to unseat the PCIe 4.0 Firecuda 520. That makes this the first drive we’ve tested to beat a Samsung 970 series drive in a real-world test. Great job Seagate.

Our final benchmark is a directory copy from a massive 100GB folder of files stored on the drive to a new folder. As this is using the same drive as the source and the destination, and the directory has a mixture of data of all different kinds the transfer rates will be a lot less than the headline sequential results. Lower is better in this case.


All in all the Seagate Firecuda 520 sets a new benchmark for home PC storage performance. The PCIe 4.0 technology provides a real-world advantage compared to PCIe 3.0 drives and unseats our previous champ, the Samsung 970 EVO comfortably. Add to that an extremely generous MTBF rating and warranty, and Seagate's Firecuda 520 is our new favourite M.2 SSD.
