Upgrading the harddrive to 4TB


A client asked me to expand his harddrive for his 27' late 2009 iMac.

Serial number of iMac: W80213R75PE

He wants to expand it to 4TB. I saw all the post on the internet regarding the temperature sensor. So that it has to be the same brand harddrive as installed now.

This is the information regarding the harddrive:'

Verbindingssnelheid: 3 gigabit

Beschrijving: AHCI Version 1.20 Supported


Capaciteit: 1 TB ( bytes)

Model: ST31000528ASQ

Revisie: AP24

Serienummer: 6VP42QJB

Native Command Queuing: Ja

Queue Depth: 32

RPM: 7200

Type partitie-indeling: GPT (GUID-partitietabel)

S.M.A.R.T.-status: Gecontroleerd

'So its a Seagate 7200RPM. I am looking on the internet, but most Seagate harddrives are 5900RPM. I am wondering if there is a big difference in terms of speed and if those drives would work:




I also found a SSHD from seagate running at 7200RPM. Will this be supported and will there be problems regarding the temperature sensor?


Hoping for a quick reply. Thanks a lot!

I would call OWC's tech support before buying and insure what the maximum drive is for this model.
