## Questions & Answers

**Q: What's the RPM?**
A: It seems to use a variable RPM between 5200 and 7200.Source:http://www.techpowerup.com/forums/threads/western-digital-intellipower-hard-drives.178122/

**Q: Will this work in a PS4?**
A: Yes, but you would need to also purchase a Nyko Data Bank to make this work, even then there may be requirements depending on the size (ie: sleep mode).

**Q: When i click "compare to similar items" the chart shows that this drive is 10000 rpm.  is this chart inaccurate?**
A: All WD Green drives are 5400RPM. I am not sure where you saw the 10,000RPM specs but they are definitely not for the GREEN Series of drives. The Green series have better cooling and are much more quiet than the faster RPM drives but are slightly slower in performance. Hope this helps!

**Q: is this oem**
A: Yup.  Genuine WD, packaged for system integrators.No instructions, documents, cables ..... Not a retail package.It saves you a few bucks, if you know what to do and have the odd bits on hand.
