Compatibility: Unlike desktop drives, these drives are tested for compatibility and optimum performance.

Neuestes Update: Der Load-Cycle-Counter der neueren Platte hat sich nicht linear weiter erhöht. Und das ohne weiteres Zutun. Komisch, aber ok. All results in MB/s. Test 1 (Windows Defender); Test 2 (Importing Pictures); Test 3 (Video Editing); Test 4 (Windows Media Center); Test 5 (Adding Music); Test 6 (Starting Applications); Test 7 (Gaming) Recently, there has been a discussion regarding the recording technology used in some of our WD Red hard disk drives (HDDs). We regret any misunderstanding and want to take a few minutes to discuss the drives and provide some additional information. The table below lists the hardware used in our current hard drive-testing machine, which remains unchanged throughout all of our testing. Each drive used for the sake of comparison is also listed here. SMART hat über das USB-Adapter-Gedöns nicht funktioniert, also habe ich die Platte mutig ins laufende NAS geworfen. Hot-Plug sollte das Synology ja können. Platte 2 einfach rausziehen, die Platten im Rahmen ummontieren und die neue 6TB reinschieben. Fertig! Keine 5 Minuten für die Hardwaregeschichte.

Since drive 1 is a consumer drive it goes into a retry loop, repeatedly attempting to read and correct the bad sector. WD Red Pro 22TB hard drives feature Western Digital’s proprietary OptiNAND™ technology which leverages integrated iNAND embedded flash to perform key housekeeping functions, freeing up more capacity and improving the overall drive performance. Also ganz so beunruhigt bin ich nicht, aber dass die beiden sich unterschiedlich verhalten, ist schon ein bißchen komisch.

One of the best-known storage benchmarking tools is HD Tune, as it’s easy to run, covers a wide-range of testing scenarios, and can do other things such as test for errors, provides SMART information and so forth. For our testing with the program, we run the default benchmark which gives us a minimum, average and maximum speeds along with an access time result, and also the Random Access test, which gives us IOPS information. All of the transfers are conducted with the Windows tool ‘robocopy’, although our MB/s results are calculated manually as the result the tool supplies isn’t accurate.Since drive 3 is a consumer drive it goes into a retry loop, repeatedly attempting to read and correct the bad sector. Western Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures.

Since I'm also guilty here with my huge array of Caviar Greens, let me also say that every few weeks I have a batch job that reads *all* data from that array. Why on earth would I need to occasionally and repeatedly read 21TB of data from something that should already be super reliable? Here's the failure scenario for what might happen to me if I didn't:Going forward, hard drives will be tested in the PC with just 4GB of RAM installed. That’s enough to allow Windows to run with lots of breathing room, but not enough to skew our test results – something helped by the fact that our smallest real-world test transfer is 10GB. None of this means that our older results are inaccurate, per se – it just means we feel more confident with our retested ones. Drives are left unpartitioned (MBR up to 3TB; GPT for 4TB+) when tested with HD Tune and AIDA64, and are formatted with 4KB cluster sizes for PCMark 7 and real-world testing. Synthetic: PCMark 7 We’re committed to providing the information that can help make an informed buying decision for as many uses as possible. Thank you for letting us know how we can do better. We will update our marketing materials, as well as provide more information about SMR technology, including benchmarks and ideal use cases. Sometimes, synthetic benchmarks don’t tell the entire story. With our real-world testing, we can see that the Red 6TB outperforms both of the other NAS drives quite handily – topping their performance by around 20MB/s. Even though the Se 4TB outperformed the Red 6TB in earlier tests, the Red reigns supreme here. Final Thoughts
