Why the warranty from Digitec is for HD WD 4TB only 2 years and for 8TB and 10TB lasts 5 years? (WD International is always 5 years)

I have a Synology DS416Play+ with 4 6TB WD Red drives. According to my research, they are CMR discs. Is this hard drive compatible with this NAS? According to the compatibility page, the first part of the model number matches. The second is missing here at Digitec. From Synology: Western Digital Enterprise NAS 3.5" SATA HDD Red Pro WD6003FFBX - 68MU3N0 83.00A83 6TB My RED (of which 4 are currently in the NAS and one is about to drop out): WD60EFRX - 68L0BN1

Hello, Is this a retail, bulk, or even an OEM hard drive? Thank you!

I have a Synology 1517+ NAS equipped with 5 x 3Tb-WD Red (Raid 6). Two of my hard drive are dead. I would like to replace these two 3Tb-WD Red by two 6Tb-WD Red PRO. Will this configuration work knowing that there is a mix of WD Red and Red PRO with a mix of 3Tb and 6Tb capacity (I am fully aware about the fact that ony 3Tb of the two 6Tb-WD Red PRO will be considered by the NAS). I would also have 2 new 6Tb-WD Red PRO that work at 7200 rpm (with 256 Mb RAM) while the 3 remaining 3Tb-WD Red are working at 5400 rpm (with lower memory 128 Mb RAM).

I have 2 6TB in my Synology DS220+. I hear an HDD access every 2 seconds. I have also turned off everything on the NAS that can be turned off, and although there is no activity on the NAS, the 2 sec HDD access is always there. I now believe it is the HDD and not the Synology. Has anyone else had the same experience?

Is this plate also written with SMR?

Which HDD would you recommend for a Synology NAS WD Red Pro or WD Gold. I have the feeling that the WD Red Pro has a longer lifespan, but the WD Gold is filled with helium and is cheaper, is this true?

The picture is different for the 12Tb WD Red Pro variant than for the other sizes, and also does not correspond to the current picture on the WD website. Is this still an older model variant? What is different about the current one?

Hello Digitec - Has the HDD already been written with data? 12 months warranty at Digitec and how much longer at the manufacturer?

Week after week, the number of bad sectors increases. I now have more than 4000 bad sectors on a 6 TB hard drive, less than 3 months old. Is a replacement covered by the warranty?

What is included in the scope of delivery? Are screws and a SATA cable included? Possibly vibration-damped / rubberised screws?

What is the difference to the WD Red Pro which is offered with 12 TB at CHF 277?

In the specifications of the hard disk it says: "Transfer rate 750 MB/s". However, the following NAS (https://www.digitec.ch/de/s1/product/synology-ds920-0tb-netzwerkspeicher-13405988) states: "Max. Data throughput read & write at 225 MB/s. Is there any point at all in installing this hard drive or would the cheaper version with 175 MB/s also do the job? Main question: Are the 750 MB/s slowed down by the max. 225 MB/s of the NAS, i.e. can the full 750 MB/s be used at all?

I was wondering why I could read so many opposing opinions about the volume of the same WD Red (Plus) hard drives. At first I thought it was probably because of how different our perceptions are. But after these scary articles and especially the official statement from WD "For select products, Western Digital has published RPM speed within a "class" or "performance class" for numerous years rather than publishing specific spindle speeds. We also fine-tune select hard drive platforms and the related HDD characteristics to create several different variations of such platforms to meet different market or application needs" makes a lot of things clear to me and although I was planning to order my NAS HDDs today under the digitec WD promotion, I am now finally refraining from doing so. At least with Iron Wolf I know that they are noisy 7200 rpm drives. At least with Iron Wolf I know that they are loud 7200 rpm disks and not from an undefinable 5400 RPM CLASS which then do not have 5400 rpm at all but 7200 rpm with a lot less performance. https://www.hardwareluxx.de/index.php/news/hardware/festplatten/54073-hwl-nutzer-deckt-irrefuehrende-rpm-angaben-bei-wd-festplatten-auf.html https://www.reddit.com/r/DataHoarder/comments/ikk0rv/psa_multiple_wd_5400rpm_drives_are_actually/ https://arstechnica.com/gadgets/2020/09/western-digital-is-trying-to-redefine-the-word-rpm/
