Seagate NAS HDD Internal hard ST4000VN000 3.5 "4TB SATA III (Personal Computers)
I ordered 4 discs for my new Synology NAS. It was a disaster! Defective areas every day, on all disks. Fortunately, the Amazon return policy is excellent, convenient and fast. Congratulations and thank you! Seagate is the pointed 0!
