I have bad experience with Seagate, this is my second HD. I decided for 1TB or 2 TB Western Digital 1.0TB WD Black Hard Disk Drive 3.5-Inch | SATA 6.0Gb/s | 7200RPM | 64MB Cache https://eshop.macsales.com/item/Western%20Digital/WD1003FZEX/ I do not like invest in SSD drive because iMac 1,1 is old and who knows how long will be good and the next one will be PC. Thank you.
