Storage Pool Creates Incorrect Size

Post by dianzisongyang »

Model: F2-221
HDD1: 3.84TB Seagate SATA SSD (Single Disk Mode)
HDD2: *Intel 1.6TB SATA SSD (Single Disk Mode)

HDD1 has been working correctly. Split into a few partitions. 3.84TB becomes 3.49TiB (approximately). Good.

I recently received a used Intel SSD. Capacity is 1.6TB, and I tested all blocks/sectors good in Windows and macOS. In Windows, shows as 1490GB available (TiB vs TB). I understand the conversion.

When I add the new SSD into the TNAS, then create a new pool, TOS defaults to "1.0TB" for single disk mode and after formatting it makes a 937GB volume, which does not make sense. Ideally I want to format the whole disk and then split it into a few partitions, but TOS refuses to give me the full 1.6TB (1490GiB) to use. What can I do?

The 1.6TB SSD (HDD2) in question is the following unit:

Code: Select all

INTEL SSDSC2BB016T4
Checked for bad sectors using TOS: no bad sectors. Formatted the Storage Pool which is still stuck at 1.0TB, and created a volume and it is 921.38GB. Compared to Windows 10, I'm missing out on over 500GB of space. Very frustrating.
