does it need separate power or will it work with a SATA to USB cable? I have a SATA cable for my internal SSDs I use for video and doesn't require external power.
Asked by: Che
An external power source or enclosure will be required to use this drive with a USB port, because a USB port will not be able to provide enough power to run the drive.

Seagate 12TB IronWolf 3.5" Internal NAS Drive (BH #SEST12000V8 MFR #ST12000VN0008), Is it compatible with NAS Synology DiskStation DS1522+? If yes, what is the part number and firmware for it?
Asked by: phattharapong
Not necessarily. The compatible drive is ST12000VN0008 - 2YS101. Note the last 6 characters after the dash. The drive currently being sold by B&H (as of 1/28/23) is ST12000VN008-2PH103. Synology software will give an incompatible drive ERROR for the drives ending in 2PH103. Just found this out the hard way after buying as a bundle.
