Hardware, storage and network planning
StorageReview with the RAID caveat
Two IronWolf Pro 20TB, RAID 1 in the configuration section. SMB 4K 1,128/508 IOPS read/write; 128K 115/98 MB/s. Conclusion ‘RAID 6’ is impossible on two disks and is not used.[5]
PCMag folder copy
RAID 1 9.02TB, 4.9GB mixed folder 87/87 MBps. Drive models unnamed.[6]
Drive replacement access
The current official table marks SATA hot-swap support. The 2022 NASCompares tour describes shutting down to open the enclosure and replace drives. Hardware support and safe physical access are different considerations; follow the current hardware guide when replacing a disk.[1][7]

Questions before buying
RAID 6 on TS-233?
No. Two bays. StorageReview’s closing RAID 6 phrase is treated as a typo; tests used RAID 1.[5][1]
How fast is it?
About Gigabit line rate on large files (PCMag 87 MBps mixed; StorageReview 115 MB/s 128K SMB).[6][5]
2.5GbE?
Not built in. NASCompares mentions an optional USB adapter without measuring it. TS-216G has native 2.5GbE.[1][7]
Plex transcode?
NASCompares: Plex without native transcoding.[7]
Upgrade RAM?
No. 2GB soldered.[1]
