Seagate Desktop SSHD 4TB ST4000DX001 Consumer Hybrid HD Review

PCMark Sequential Run Performance Increases

We mentioned earlier that the Seagate 4TB SSHD uses an algorithm to determine the most used files and as you use them more often they get moved to the SSD portion of the drive. PCMark 7 and 8 use three runs of each test and the results are all kept then averaged so we can show the Seagate 4TB SSHD’s performance increase across the sequential runs and if the algorithm is operating correctly we should see an increase as it progresses from run #1 to run #3.

Our First Table is PCMark 7 and as you can see as the files are used the drive gets faster as the file usage sorting algorithm gets a better idea of what you’re using.

PCMark7 Run 1 Run 2 Run 3
Windows Defender 1.8 MB/s 4.7 MB/s 5.2 MB/s
Importing Pictures 8.7 MB/s 12.3 MB/s 12.2 MB/s
Video Editing 18.9 MB/s 21.1 MB/s 21.4 MB/s
Windows Media Center 8.2 MB/s 8.3 MB/s 8.5 MB/s
Adding Music 1.4 MB/s 1.5 MB/s 1.5 MB/s
Starting Applications 4.4 MB/s 22.0 MB/s 22.7 MB/s
Gaming 5,0 MB/s 11,0 MB/s 12,9 MB/s

This is the storage benchmark section of PCMark 8 and PCMark 8 reports both the speed in MB/s and seconds to completion, in this table it’s the seconds for completion and yet again the drive completes the tasks faster as the files are moved to the Nand Flash.

PCMark 8 Run 1 Run 2 Run 3
World of Warcraft 108.5 sec. 96.4 sec. 92.7 sec.
Battlefield 3 292.0 sec. 264.2 sec. 222.2 sec.
Adobe Photoshop Light 182.7 sec. 147.5 sec. 124.4 sec.
Adobe Photoshop Heavy 443.2 sec. 401.3 sec. 389.6 sec.
Adode InDesign 126.2 sec. 105.8 sec. 89.5 sec.
Adobe After Effects 120.2 sec. 107.4 sec. 85.3 sec.
Adobe Illustrator 136.3 sec. 93.5 sec. 84.1 sec.
Microsoft Word 42.5 sec. 32.2 sec. 29.6 sec.
Microsoft Excel 21.8 sec. 14.2 sec. 10.3 sec.
Microsoft PowerPoint 19.3 sec. 11.6 sec. 10.1 sec.

Now we switch to the MB/s readings from PCMark 8 and across the PCMark tests we can see that as we use the files they are indeed moved to the Nand Flash the drive transfers faster.

PCMark 8 Run 1 Run 2 Run 3
World of Warcraft 7.6 MB/s 9.8 MB/s 11.2 MB/s
Battlefield 3 5.4 MB/s 6.6 MB/s 9.2 MB/s
Adobe Photoshop Light 33.7 MB/s 63.1 MB/s 140.4 MB/s
Adobe Photoshop Heavy 61.4 MB/s 108.2 MB/s 134.1 MB/s
Adode InDesign 13.6 MB/s 18.7 MB/s 29.4 MB/s
Adobe After Effects 5.3 MB/s 8,9 MB/s 22.4 MB/s
Adobe Illustrator 7.3 MB/s 22.4 MB/s 38.1 MB/s
Microsoft Word 13.6 MB/s 57.8 MB/s 62.7 MB/s
Microsoft Excel 8.2 MB/s 17.5 MB/s 54.9 MB/s
Microsoft PowerPoint 9.7 MB/s 41.2 MB/s 69.7 MB/s

Keeping in mind that the Seagate 4TB SSHD isn’t about replacing a SSD backed by a platter drive which is the optimal arrangement we see in consumer computing but if you only have the cash for one or the other the Seagate 4TB SSHD is a good choice, You get the boosted speed of the SSD sorting most used files onto the Nand Flash and pretty decent platter transfer rates to boot, Later when you have your war chest refilled you can toss an SSD in front of the Seagate SSHD and have a better drive arrangement than just a SSD in front of a normal platter drive.

The Steam Deck – Valve delivers an excellent PC handheld

Valve is an interesting company that seems to try to be a lot of things at the same time. Games company, software hub/store and hardware company. Valve is all of these. When it comes to hardware the company has had mixed success. I think many of us remember the Steam Machines. These compact computers running SteamOS, a Linux based OS, were supposed to make Windows PC’s obsolete for gaming. They didn’t succeed. Valve also released a specific controller, the Steam Controller, which also did not exactly set the world on fire. In hindsight though both these products have paved the way for the product I am testing today, the Steam Deck, Valves attempt to compete with the Nintendo Switch in the handheld market.

  1. Sounds like a great drive but…an decent 120/240gb SSD and a 3+tb storage disk is almost the same price and gives you much much faster performance??
