The exponential increase in data storage requirements over the last decade or so has been handled by regular increases in hard drive capacities. Multiple HDD vendors supply them to cloud providers (who get the main benefits from advancements in hard drive technologies), but, Seagate is the only one to also focus on the home consumer / prosumer market. In the last three generations, we have seen that Seagate has been the first to target the desktop storage market with their highest capacity drives. The 10 TB BarraCuda Pro was released in Q3 2016, and the 12 TB version in Q4 2017. Seagate is launching the 14 TB version today.

Introduction

The Seagate BarraCuda Pro 14TB is a 7200RPM SATAIII (6 Gbps) hard drive with a 256MB multi-segmented DRAM cache. It features eight PMR platters with a 1077 Gb/in2 areal density in a sealed enclosure filled with helium. The main change compared to the 12TB version introduced last year is the usage of Seagate's second-generation two-dimensional magnetic recording (TDMR) heads, allowing for higher areal density (1077 Gb/in2 vs. 923 Gb/in2 without TDMR). If you are curious about how TDMR enables this, we have a brief explanation towards the end of this review.

According to Seagate, the 14TB BarraCuda Pro typically draws around 6.9W, making it one of the most power efficient high-capacity 3.5" hard drives in the market. It targets creative professionals with high-performance desktops, home servers and/or direct-attached storage units. It is meant for 24x7 usage (unlike traditional desktop-class hard drives) and carries a workload rating of 300TB/year, backed by a 5-year warranty. The drive also comes with a bundled data-recovery service (available for 2 years from date of purchase). The various aspects of the drive are summarized in the table below.

With the launch of the 14TB BarraCuda Pro, Seagate has also updated the model numbers for the other capacities in the series. While performance numbers remain relatively unchanged, capacities 10TB and up come in at 690g, while the 8TB is at 650g. The 6TB, however, is at 780g, pointing to different number of platters for different capacities, and even non-helium technology for the smaller ones.

A high-level overview of the various supported SATA features is provided by HD Tune Pro.

The main focus of our evaluation is the performance of the HDD as an internal disk drive in a PC. The other suggested use-case for the BarraCuda Pro is in direct-attached storage devices. The evaluation in these two modes was done with the help of our direct-attached storage testbed.

The internal drive scenario was tested by connecting the drive to one of the SATA ports off the PCH, while the Akitio Thunder3 Duo Pro was used for evaluating the performance in a DAS. The Thunder3 Duo Pro was connected to one of our testbed's Thunderbolt 3 Type-C port. The controller itself connects to the Z170 PCH via a PCIe 3.0 x4 link.

    Is the Exos 14TB out? I cannot find it anywhere yet

    The only difference I know of besides durability ratings is that the Exos X10, X12 line uses Helium

    Drives of this class usually fairly quiet, because the platter dont push speed to extreme limits.

    Barracuda Pro is designed to be integrated in a PC or workstation in single, non-RAID configuration with medium workloads. Exos is high end, server grade HDDs, designed for maximum performance in highest workloads in it's class, 24/7 operation in RAID setup. There is also huge difference in endurance between those two.

    Factory output capacity of 10/12/14TB HDDs is around 10-15 pcs per day, so the price reflects higher production costs

    I remember how bad I felt when my 4GB Western Digital drive on my Gateway 2000 P5-75 running Windows 95 failed. I lost all that data. I wonder what its like loosing 14 TB. Reply

    A similar loss of an old 4gb drive back in 2004 taught me the value of backups. Any data I really care about is on at least 2 independent drives. If my desktop dies, I can restore from my NAS, if my NAS dies I can restore from my desktop, some stuff (eg music) is also on my laptop and phone. More critical stuff is also backed up to the cloud, it's a subset of everything both for cost reasons and because for privacy related ones I refuse to upload full system images. Reply

    If you care about your data, you need to have another drive as backup. Although with 14TB (even more if building an array out of 14TB drives), you might well be into LTO tape land for your backup needs. Reply

    Yeah this is the problem with drives costing $500 is that you then need to buy 2 or 3 of them to have good backups! Reply

    Slightly earlier generations of LTO are looking quite good these days, a fair few used drives on ebay. LTO4 looks optimal price-wise, though of course a single tape is nowhere near enough to archive one of these modern rust spinners, but sensible use of subfolders can take care of that. If you really care about your data, LTO5 isn't that expensive, new units on ebay UK atm for 225 UKP. Used prices do jump a lot for LTO6, though ironically the last new LTO6 tape I bought off ebay only cost me 11 UKP. :D

    And of course, suitabe used SAS cards cost diddly squat.

    Either way, the problem with using extra rust spinners as backups is they're prone to the same issues such as shock, mechanism degradation, etc. If you do go that route though, always buy the extra drives from different sources, helps ensure the drives come from different batches (that way if there's a batch fault, it's less likely to affect more than one of your drives).

    4GB would have been quite a hefty drive for a P75. Reply
