Seagate’s Barracuda Professional 12TB reminds us why not less than some exhausting drives can stay related regardless of the swift encroachment of SSDs. Till we reviewed its predecessor the Barracuda Pro 10TB final 12 months and tasted its 250MBps learn efficiency, we hadn’t given exhausting drives a lot thought for some time. To be blunt, 12 months after 12 months of 120MBps – 150MBps switch charges had turned boring in a world of blindingly quick SSDs—even with the regular and admittedly monumental will increase in capability.

The Barracuda Professional 12TB reviewed right here is only a hair quicker than the 10TB model, however the extra 2TB of capability is actually a improbable factor. We are able to keep in mind $800 4GB exhausting drives (in addition to Eight-inch floppies and Winchester drives if we’re sincere), so shade us intrigued to see simply how far Seagate and the business can take issues.

Specs and design

The Barracuda Professional 12TB is a 7,200 rpm, three.5-inch exhausting drive with 256MB of onboard cache. It employs a SATA 6Gbps interface, makes use of PMR (Parallel Magnetic Recording), is full of helium for much less drag, and is alleged to attract 7.Eight watts—a comparatively small quantity of juice for a tough drive.


Seagate’s Barracuda Professional 12TB appears like exhausting drives have all the time seemed, however the newest applied sciences enable way more capability and higher sustained throughput.

Seagate warranties the Barracuda Professional for hefty 5 years, and there’s two years of Seagate Rescue information restoration included. (Hold your fingers crossed that any drive failure happens early—if in any respect). Past that, it’s simply your run-of the mill exhausting drive in dimension and look.


We check utilizing the AS SSD and CrystalDiskMark benchmarks. To these artificial checks we add real-world copying of a single massive 20GB file, in addition to a 20GB mixture of smaller information and folders.

The considered a tough drive transferring massive quantities of contiguous information at 250MBps was fantasy not so way back. The Barracuda Professional 12TB does it, and in our testing, it did so constantly. Even small 4K efficiency is constantly 30 p.c to 100 p.c improved over the old fashioned.

New college versus old style. The ES.2 wasn’t a quick drive in its day, nevertheless it wasn’t actually sluggish. The Barracuda Professionals make its throughput look anemic.

AS SSD (not proven) really rated the Barracuda Professional 12TB a bit slower than CrystalDiskMark did, however CDM’s ranking is definitely nearer to what you’ll see in the true world. That is bolstered by our 20GB copy checks, which just about flat-lined (in a great way) at 250MBps, each studying and writing.

The 12TB model is barely reasonably quicker than the 10TB Barracuda Professional.

Observe that with all exhausting drives, switch charges range in response to the place the information is on the platter. Because the outer sectors are crammed, and extra information is written to the drive, speeds might drop because the inside sectors come into play. With the comparatively small quantities of information we used, this phenomenon gained’t present up.
