  1. I have the same issue her on my MacBook Pro MacOS 10.14.6 UnRaid 6.7.2 SMB Download averaging at 37MB/s SMB Upload averaging at 117MB/s @limetech Are there any informations how to address this issue?
  2. Let’s take 5 years as an example. From my calculation TBW will be at about 1000 maybe a bit less because of WA and the larger drive size. 970 will be way beyond the specified TBW. But still in warranty. SMART Test will again be failing because of percentage used over 100%. I‘ll again have no idea if the drive fails or not even if it still works. PM983 will be still in spec for TBW but out of warranty because of the time. Percentage used and SMART Test will be ok but no waranty. Usually I claim warranty when there is any but if the claim process is costly and the prospects of success are low. I just leave it. Wich is my experience for Samsung consumer drives. No idea if this will be different to Samsung Enterprice drives. Advance RMA maybe? WD offers that. What Formfactor goes: My MB accepts 22110. As you have both drives installed: Do you encountered any differences in read or write speads? How is each percentage used value scaling to your TBW values? Are they indead scaling different as I assumed above? Could you maybe post those values for each drive as a reference?
  3. Trim was always running daily on my SSD. Can I improve anything about WL? Would you rather suggest buying a bigger consumer SSD than a better rated smaller enterprise SSD to just leave space free and to hope for the controller to make good use of it and thereby reducing the WA? About 180-200€ for a Samsung PM983 960GB M.2 seams reasonable for me. Would you consider that as enterprise grade or would rather buy a Samsung 970 Evo M.2 1TB for about the same price? Thank you very much for sharing your expertise on that.
  4. Thanks for your detailed Explanations. Downloads and Plex Transcods cannot be the main reason for the nearly 400 TBW. That seems more reasonably to me. Or am I understanding anything wrong here? If not, overprovisioning seems as the most reasonable approach to me. Is it possible to over provision any SSD Myself? I don't have any VM vdisks and my Docker Image is about 100gig so 500gig of usable space is plenty enough for my use. Switching to 1 tb or let's say overprovisioned 840gigs would already be a huge upgrade for me but I don't want to lose the speed of NVMe. I cannot find any fast NVMe drives that are rated for significantly higher TBW.
  5. Can anyone give me a hint for a good M.2 SSD for write intensive workloads?
  6. Is it possible to combine a 500 GB and a 1000 GB NVMe in RAID1 to expand it later?
  7. Is that a good idea? Can that be Reduced in any way?
  8. yes I specifically decided for an NVMe cache because of the Containers. Maybe That was a Pretty costly decision based on that experience. 😖 I think I'll use the drive until it fails. But from now on I won't have any warning for the point of failure, because SMART already failed. Would adding a second cache drive in RAID1 be a good idea? My Mainboard (Supermicro X11SSi-LN4F) only has one NVMe slot. Will RAID1 work with a PCI NVMe extension?
  9. The TBW value also looks pretty high to me so much written and only 1/4 of that read. My whole array is only 1/13 of that amount of data (TBW). Do that sound plausible to you? Additional info: I'm not moving huge amounts of data regularly. But I have quite a few Docker containers (35ea) running, logging writing to Databases and regularly updated.
  10. The RMA Procedure of Samsung is pretty stressful. 🤯 And no advance RMA so pretty much downtime too.
  11. Anyways... You would say the failing SMART test is just because of the prediction and nothing else? And the Prediction is noting I have to be worried about?
  12. I'm not sure about that this website says 400 TBW for all 3 sizes. But I have also read 200 at any place. https://www.samsung.com/de/memory-storage/960-evo-nvme-m-2-ssd/MZ-V6E500BW/
  13. I also noticed that but on what measure is this life prediction made? The Drive was sold with an MTBF of 1,5 million hours and 400 TBW. Neither of them is reached o exceeded.
  14. Hey guis, My NVMe cache went bad in SMART test but I cannot see why? Physically it is working absolutely fine. It is not very old and there are not too much TB Written. Here are some screenshots and additionally the smartctl output. Maybe someone can help me to interpret what's the issue here and if I have to be afraid to have the Cache fail physically soon. === START OF INFORMATION SECTION === Model Number: Samsung SSD 960 EVO 500GB Serial Number: S3EU************* Firmware Version: 2B7QCXE7 PCI Vendor/Subsystem ID: 0x144d IEEE OUI Identifier: 0x002538 Total NVM Capacity: 500,107,862,016 [500 GB] Unallocated NVM Capacity: 0 Controller ID: 2 Number of Namespaces: 1 Namespace 1 Size/Capacity: 500,107,862,016 [500 GB] Namespace 1 Utilization: 244,207,935,488 [244 GB] Namespace 1 Formatted LBA Size: 512 Namespace 1 IEEE EUI-64: 002538 5371b0e432 Local Time is: Mon Jul 29 00:23:32 2019 CEST Firmware Updates (0x16): 3 Slots, no Reset required Optional Admin Commands (0x0007): Security Format Frmw_DL Optional NVM Commands (0x001f): Comp Wr_Unc DS_Mngmt Wr_Zero Sav/Sel_Feat Maximum Data Transfer Size: 512 Pages Warning Comp.
