Western Digital 10TB WD Red NAS Internal Hard Drive - 5400 RPM Class, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5" - WD100EFAX (Old Version)

I picked one of these up last year and have been using it on a Linux system using LUKS encryption. It's still going strong, and I've yet to see any unrecoverable write errors in btrfs. Here's the output of smartctl:=== START OF INFORMATION SECTION ===Device Model: WDC WD100EFAX-68LHPN0Firmware Version: 83.H0A83User Capacity: 10,000,831,348,736 bytes [10.0 TB]Sector Sizes: 512 bytes logical, 4096 bytes physicalRotation Rate: 5400 rpmForm Factor: 3.5 inchesDevice is: Not in smartctl database [for details use: -P showall]ATA Version is: ACS-2, ATA8-ACS T13/1699-D revision 4SATA Version is: SATA 3.2, 6.0 Gb/s (current: 6.0 Gb/s)Local Time is: Fri May 17 16:33:50 2019 PDTSMART support is: Available - device has SMART capability.SMART support is: Enabled=== START OF READ SMART DATA SECTION ===SMART overall-health self-assessment test result: PASSEDGeneral SMART Values:Offline data collection status: (0x82) Offline data collection activitywas completed without error.Auto Offline Data Collection: Enabled.Self-test execution status: ( 0) The previous self-test routine completedwithout error or no self-test has everbeen run.Total time to complete Offlinedata collection: ( 93) seconds.Offline data collectioncapabilities: (0x5b) SMART execute Offline immediate.Auto Offline data collection on/off support.Suspend Offline collection upon newcommand.Offline surface scan supported.Self-test supported.No Conveyance Self-test supported.Selective Self-test supported.SMART capabilities: (0x0003) Saves SMART data before enteringpower-saving mode.Supports SMART auto save timer.Error logging capability: (0x01) Error logging supported.General Purpose Logging supported.Short self-test routinerecommended polling time: ( 2) minutes.Extended self-test routinerecommended polling time: (1133) minutes.SCT capabilities: (0x003d) SCT Status supported.SCT Error Recovery Control supported.SCT Feature Control supported.SCT Data Table supported.SMART Attributes Data Structure revision number: 16Vendor Specific SMART Attributes with Thresholds:ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE1 Raw_Read_Error_Rate 0x000b 100 100 016 Pre-fail Always - 02 Throughput_Performance 0x0004 130 130 054 Old_age Offline - 1083 Spin_Up_Time 0x0007 167 167 024 Pre-fail Always - 351 (Average 435)4 Start_Stop_Count 0x0012 100 100 000 Old_age Always - 245 Reallocated_Sector_Ct 0x0033 100 100 005 Pre-fail Always - 07 Seek_Error_Rate 0x000a 100 100 067 Old_age Always - 08 Seek_Time_Performance 0x0004 128 128 020 Old_age Offline - 189 Power_On_Hours 0x0012 099 099 000 Old_age Always - 775010 Spin_Retry_Count 0x0012 100 100 060 Old_age Always - 012 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 2422 Unknown_Attribute 0x0023 100 100 025 Pre-fail Always - 100192 Power-Off_Retract_Count 0x0032 098 098 000 Old_age Always - 3338193 Load_Cycle_Count 0x0012 098 098 000 Old_age Always - 3338194 Temperature_Celsius 0x0002 185 185 000 Old_age Always - 35 (Min/Max 24/41)196 Reallocated_Event_Count 0x0032 100 100 000 Old_age Always - 0197 Current_Pending_Sector 0x0022 100 100 000 Old_age Always - 0198 Offline_Uncorrectable 0x0008 100 100 000 Old_age Offline - 0199 UDMA_CRC_Error_Count 0x000a 200 200 000 Old_age Always - 0SMART Error Log Version: 1No Errors Logged

Purchased two 10TB drives during Prime Day (for under $216 each) in July '19 to go into a Synology 1019+ (bought at the same time). I also bought two of the drives from another vendor (for the same price). Had to split the order as both Amazon and the other vendor had a two drive limit, which is a bit odd for NAS drives which are usually bought in multiple units. Anyway, it let more than one vendor get in on the sale. Keeping an eye out now for one more to fill the last drive bay.Started out with two drives in SHR1 (one drive fault tolerance). It took about three days for the NAS to initialize them. The second two drives arrived, I put them in and told the NAS to switch to SHR2 (two drive fault tolerance). Eight days later, I'm 40% through initializing the second drive! The good thing is that this conversion should give the drives a good initial workout.So far, no bad sectors. The drives run at about 35C / 95F in a room that is about 75F. Drives are nice and quiet. I can hear the usual hard drive clucking sounds if I'm right next to it, but from six feet away there is no sound. Hopefully the drives hold up and I'll update the review if any issues come up.Only complaint is that it would be nice if there was a more comprehensive test suite like the Seagate Iron Wolf drives, which Synology can access directly.

I thought I would post my own experiences in trying to mount this 10TB drive into a brand new Win10 build. Current application for the drive is media storage on a media PC. Review will follow.Specs: Asus Z270K mobo, Samsung m.2 960 500gb boot drive, 16TB Ripjaw DDR4, GTX550Ti GPU, i7 4.2ghz Kaby Lake quadcore CPU, HAF XB case. The case allows for "hot-swapping" of drives.The main issue was that the disk management was having trouble"seeing" the 10TB Red NAS drive in an internal bay but could recognize it in an external enclosure (which does no good for long-term use). Disk management "saw" the drive as having two partitions but when I right-clicked over options to try and format it, the selections were grayed-out and couldn't be accessed.I called WD Customer Support the following steps rectified the issue. The disclaimer here is that you should only try this if you know what you're doing. It will wipe the drive clean and if you select the wrong drive, you will be in a world of poop.The screenshot will hopefully help.1. Left click Cortana icon2. In the search panel type in CMD (this will bring up the black command screen with text that you see on the upper left)3. Type diskpart (all one word)4. Type list disk (separate words)5. Take note of which drive you want the system to format (in my case it was Disk 1 which is 9TB). YOUR DISK NUMBER MAY VARY.6. Type select disk (insert number no parentheses, separate spaces)7. type clean DOUBLE CHECK THAT YOU ARE WIPING THE CORRECT DRIVE8. right click on windows start menu and scroll up and select Disk Management9. the drive should appear and you can then select it and begin the formatting process4 stars: data transfers at 150-160MB/s internal SATA and 90-130 on USB 3.0 on a Sabrent enclosureEasy install, but as described above, I had hassles actually getting Windows 10 do recognize the drive. This may be due to the fact that it was initially formatted on a Windows 7 PC. It's a pretty quiet drive so far and the data access speeds are just dandy for a HTPC.
