Seagate Barracuda Pro 12TB review

Seagate has recently released three new 12TB 3.5-inch HDDs with the first two being the IronWolf 12TB and IronWolf Pro 12TB which are designed specifically at NAS environments. The third drive that Seagate announced is the BarraCuda Pro 12TB which is aimed at desktop users, creative professionals, and gamers. These drives are based on helium technology and have eight platters inside.

Today we will review the Seagate BarraCuda Pro 12TB hard-drive which is the world’s highest-capacity desktop hard-drive on the market. The Seagate BarraCuda Pro 12TB HDD comes with a speed of 7200RPM which also makes it the fastest 12TB desktop drive on the market. It has a continuous read and write speed of 250 MB/s and it comes equipped with a large 256MB cache size which will help with loading applications and files faster.

While the average user might not need a drive this massive in capacity, there are creative professionals who work with high-resolution 4K content, hardcore PC gamers who install their entire Steam library, and data hoarders that would love to have a drive such as the BarraCuda Pro 12TB. Large hard-drives such as the BarraCuda Pro 12TB are still relevant in the industy due to their reliability and low price.

The Seagate BarraCuda Pro 12TB HDD utilizes the SATAIII 6Gbps interface, and according to Seagate, it is said to draw around 7.8 watts in operating mode and 4.8W in idle mode making it one of the most power efficient 3.5" hard drives on the market. Seagate has designed the BarraCuda Pro 12TB HDD for 24x7 usage and it carries a workload rating of 300TB/year or 820GB/day.

In this review we will be benchmarking the BarraCuda Pro 12TB HDD against the Western Digital Black 6TB to see which one is the fastest. Western Digital's Black hard-drives are available up to 6TB of capacity, and also come with a 5-year of warranty.

Test Methodology

Test Setup
Processor:AMD Ryzen 7 1700X (3.8Ghz)
Motherboard:MSI X370 xPower Titanium (BIOS v1.9)
RAM:Ballistix Elite 16GB (2x8GB) DDR4 3200Mhz
Graphics Card:Nvidia GeForce GTX 1070
Storage:Seagate BarraCuda Pro 12TB
Western Digital Black 6TB
Power Supply:SilverStone ST80F-TI (800W)
Heatsink:Noctua NH-D15
OS:Windows 10 Home 64-Bit
Thermal Compound:Noctua NT-H1
Case:Corsair 400C

The testing was done on a fresh install of Windows 10 64-bit with the latest windows updates installed. To make sure these drives perform at their maximum performance, we have disabled all the power saving features in the BIOS (C6-state, etc) and set the power option to high-performance in Windows 10. We have also gone ahead and disabled a bunch of unnecessary services and removed all the bloatware from Windows 10 to make sure there were as few processes running as possible during the testing.

We'll be using the AMD Ryzen 7 1700X processor overclocked to 3.8Ghz and the MSI X370 xPower Titanium motherboard with the latest BIOS version which at the time of writing this is v1.90. The Ballistix Elite DDR4 (2x8GB) 16GB memory kit was run at 3200MHz with 16-16-16-38 1T memory timings.

Benchmark Software:

+ CrystalDiskMark
+ ATTO Disk Benchmark
+ HD Tune Pro
+ IOMeter

Other than that, the BarraCuda Pro 12TB is easily the best HDD that I have ever tested and I believe it deserves our Elite award.
