Seagate BarraCuda Pro 14TB HDD Review: Massive Storage for Desktops
by Ganesh T S on September 10, 2018 8:01 AM ESTPerformance - Direct Attached Storage Mode
Seagate also sells the BarraCuda Pro Compute drives as being suitable for use in direct-attached storage systems. We evaluated the performance in such a usage scenario using one of the highest performing 2-bay DAS units currently in the market - the Akitio Thunder3 Duo Pro, connected to our testbed via a Thunderbolt 3 interface.
Prior to processing real-life workloads, we first checked quick artificial access traces using ATTO and CrystalDiskMark.
We find that the performance remains consistent irrespective of workload size as long as the sequential access characteristic holds. Two drives in RAID 0 can sustain 520 MBps+ reads and writes. RAID 1 performance is similar to the standalone drive performance.
Both RAID0 and RAID1 configurations were subject to our standard DAS test suite described in the previous section. The robocopy test suite gave the following results.

| Write Bandwidth | Read Bandwidth | |||
| RAID 0 | RAID 1 | RAID 0 | RAID 1 | |
| Photos | 299.52 | 182.11 | 383.84 | 196.73 |
| Videos | 400.26 | 214.63 | 400.44 | 203.24 |
| Blu-ray Folder | 423.90 | 218.47 | 403.24 | 206.67 |
There is no difference in the performance consistency between either RAID configuration. The behavior is largely similar to the internal drive scenario, except for the RAID 0 absolute bandwidth numbers. Thanks to the enclosure's fan, the temperature increase is also not as much as what we observed in the internal drive case, though we do see the temperatures in the RAID 1 case being slightly more than the RAID 0 case due to the workload distribution.
We also processed select workloads from PCMark 8's storage bench.

| Adobe Illustrator | 224.29 | 178.66 | 9.06 | 8.81 | |
A significant speed-up in response time is achieved while dealing with multimedia files stored in a RAID 0 configuration of two BarraCuda Pro 14TB drives in a Thunderbolt 3 enclosure. Combined with the consistency shown, we can say that our results back up Segate's claims regarding the firmware tuning of BarraCuda Pro drives for specific application scenarios.

It depends on the type of the ad. There are both pay for display and pay for click ads.Digitalclips - Sunday, October 7, 2018 - link
I wonder if the advertisers are also in receipt of web page stats, not just actual clicks. Even if you don't click we see many of the ads. People don't click on billboards at the side if interstates either.medivh - Monday, January 20, 2020 - link
I have a pihole. I didn't even realize this site had ads at all.Ryan Smith - Monday, September 10, 2018 - link
"How do I turn off video autoplay on anandtech.com please?"Unfortunately our publisher is not enabling that option. Sorry.

That's going to either drive people away from the site or increase the use of ad blockers; neither of which is beneficial.29a - Monday, September 10, 2018 - link
Fortunately Ublock Origin does enable that option.PeachNCream - Tuesday, September 11, 2018 - link
Thanks for at least looking into it Ryan. We know the ad content is a necessity for keeping the site up and running. Videos with automatic playback are just incredibly frustrating.maco - Wednesday, September 12, 2018 - link
I’m close to removing Anandtech from my ad blocker’s whitelist because the video is so intrusive.29a - Monday, September 10, 2018 - link

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
