Nice drive for NAS

By Greg
Rated 5 out of 5
Date: 2026-05-05

This drive is a good mix of price, size, and performance for a NAS. I don't need huge amounts of storage but I want performance from multiple drives for a decent price. I trust Seagate more than some other NAS drive vendors.

Purchasing this model hard drive from two other vendors out of the box drive failure. I returned them. This was perfect on installation into my 4 bay NAS.

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.
