Two Hitachi Travelstars:

http://www.newegg.com/Product/Product.a ... 6822145228

What’s the difference between them? Is one the retail version of the other or are they different products?

HD20320 is not a model number for Hitachi HDD (or at least it doesn't follow model numbering convention used by Hitachi) so I believe it's a retail kit number.

That retail kit has a discount that makes the originally higher price lower than the bare drive, plus free shipping. I'd get the retail boxed version for lower price, regardless of whether it has the same warranty or shorter.

The boxed version's reference is HTS725032A9A364, it's a 7K500 model. The bare drive is a 7K320.

Thank you. I got 2 and they're faster and quieter than my WD3200BEKT, the Hitachis have a whoosh sound without the piercing metallic whine of the WD. They sound more like 5400 RPM.

And now the big surprise. According to PassMark benchmarks...

http://www.harddrivebenchmark.net/hdd_list.php

the HTS725032A9A364 that I got has a much higher score than the bare drive version HTS723232L9A360 ... the difference is huge, 297 rank vs 805. How do you explain that?

Hitachi is still around :)

Their latest 7K500 = HITACHI Travelstar H2IK5001672SP (0S02858)

http://www.newegg.com/Product/Product.a ... 6822145361

also marketed as:

HD20500IDK/7K
0S00157
HTS725050A9A364
H2IK5001672SP
0S02858

What's the difference? The reason I'm asking is, as you can see from my OP one of the two 320s turned out much faster than the other. Is 0S02858 the real thing?

They are the same model. OEM vs Retail.

I don't know about faster. It's SATA-6Gbps though but that doesn't mean anything.

That's not a 7K500, it's a Z7K500. The ZxK disks are slimmer, only 7mm thick.

That's what "I don't know" usually means.

According to this, the HTS725050A7E630 is much faster, but you might need a new mobo to support 6GB sec.

Your link states: "The hard drive did not meet the required number of samples needed to be charted."
For all you know, you're going on a single report which could easily be bogus.
Putting your speculations in bold doesn't make up for the lack of extraordinary evidence an extraordinary claim requires.

Yes, that could be. I couldn't find any for sale either, so maybe it's too new.
