chris_netsmart Posted June 27 Share Posted June 27 (edited) I am looking at purchasing some large TB's hard drivers, but then I read up on the specs a lot of them don't mention SMR, CMR or PMR. I have seen the following on Amazon - Seagate Enterprise Capacity v6 10TB Internal Hard Drive ST10000NM0046 SATA 3.5" HDD 256MB Cache MDD - HGST He10 (HUH721010ALE601) 10TB 7200RPM 128MB Cache SATA 6.0Gb/s 3.5inch Enterprise Hard Drive (Renewed) I have google around and found that you can find out via the Smart data of the hard drive, but running smartctl, so as a test I have ran this on one of my old 10 TB hard drivers, below is the test. I have looked through and I can't see anything that talks about the technology, can someone please point to the right location root@Tower:/dev# smartctl --all /dev/sdg smartctl 7.4 2023-08-01 r5530 [x86_64-linux-6.1.74-Unraid] (local build) Copyright (C) 2002-23, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Device Model: WDC WD101EMAZ-11G7DA0 Serial Number: V******P LU WWN Device Id: 5 000cca 0b0cd5dec Firmware Version: 81.00A81 User Capacity: 10,000,831,348,736 bytes [10.0 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 5400 rpm Form Factor: 3.5 inches Device is: Not in smartctl database 7.3/5577 ATA Version is: ACS-2, ATA8-ACS T13/1699-D revision 4 SATA Version is: SATA 3.2, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Thu Jun 27 09:07:52 2024 BST SMART support is: Available - device has SMART capability.

In this case Quote Device is: Not in smartctl database 7.3/5577 so it doesn't know. Best is to check the manufacturer's specs/lists or actual drive datasheets, e.g. for Seagate https://www.seagate.com/products/cmr-smr-list/ There are also user-contributed lists around.

chris_netsmart Posted June 27 Author Share Posted June 27 thanks chaps, @JorgeB if I may ask - how did you find this information ? Quote Link to comment
JorgeB Posted June 27 Share Posted June 27 Just know the models, also and AFAIK, there are no 10TB WD/HGST or Seagate SMR drives, 8TB yes. Quote Link to comment
