Hitachi 1 TB 16MB 7200RPM SATA Bulk/OEM Hard Drive 0A38016

First some quick specs about the drive that Amazon doesn't have listed.

The drive itself is a Deskstar 7K1000.B, SATA 3.0Gb/s interface, runs at 7200 RPMs, and has a 16mb buffer. This is an OEM drive, so for those who don't know what that means, it means that it doesn't come in a retail box, or with cables, screws, a manual or anything, just the drive nicely packaged up in an anti-static bag and some foam. And Amazon does a much better job shipping OEM drives then other companies do, but that's beside the point.

I bought this drive as a replacement for a 160GB Seagate that crapped out on me, yes it mechanically crapped out on me.

The drive is a whole like quieter then the Seagate EVER was. Almost zero clicking and chatter. And you really can't tell the difference between the drive at idle and spinning at full speed, really impressive.

I purchased the Hitachi 1 TB 16MB 7200RPM SATA Bulk/OEM Hard Drive 0A38016.

According to a review at Tom's Hardware that lead me to purchase this model:
"The 7K1000.B ... is based on three platters instead of five. It still utilizes Serial ATA/300 and the same 7,200 RPM spindle speed, but the cache capacity was reduced from 32 MB to 16 MB, which didn't hurt performance at all. To the contrary, the Deskstar 7K1000.B is one of the fastest and most balanced hard drives available today. It pairs great performance with power efficiency."

I have used this drive for about a month with no problems. I formatted it HFS+ and placed it inside an OWC Firewire enclosure for use with my Mac.
Amazon shipped this particular drive in a safe, fully foam enclosed packaging. Note that because it is an OEM product it does not come with cables, manuals, software, or...Read more

Extremely cheap price wise.
1TB @ under $100
Have been happily using mine for four months now.
Not a single problem.
Noise levels are low.
At least nothing can be heard over my noisier fans...
Reliable product.

I would recommend this to a friend.
And I'll probably buying a second one.
1TB is so little ;)

For the record:
I have an old Seagate(purchased jan 2008) 250GB/8MBcache/7200rpm.
I can't really tell the difference between them (apart from the size obviously.
