[SOLVED] New drive, SMART changes within two days.

[Landstander]

New WD Black 8 TB. Did a low level format, some quick testing and copied several TB of data to it. SMART numbers have shifted since initial installation. Should I be concerned?

At Install:

And now:

All the numbers that have changed, you expect to change, since they're mainly measurements of how many times and how often the drive has been used.

The raw value of Throughput Performance is initially 0 because the drive hasn't accumulated any performance statistics. After normal activity this number would be expected to settle on some average value.

The Spin-Up Time and Temperature data are best viewed in hexadecimal. They each consist of three parameters.

• 42 949 672 960 = 0xA00000000 -> 0x000A / 0x0000 / 0x0000
  42 984 145 426 = 0xA020E0212 -> 0x000A / 0x020E / 0x0212
  
  124 555 690 013 = 0x1D0019001D -> 0x001D / 0x0019 / 0x001D -> 29C / 25C / 29C (max /min /current temperatures)
  214 750 003 238 = 0x3200190026 -> 0x0032 / 0x0019 / 0x0026 -> 50C / 25C / 38C (max /min /current temperatures)

I had identical situation, got wd black 10tb, and after two days performance attributes increased from 100.
