Buydig thru eBay has Seagate Expansion 4 TB USB 3.0 Desktop External Hard Drive STBV4000100 for $125. You can rip the drive out and use in your media server. It's 5900rpm with 4 plates cool and quiet from what I know. For the warranty, just enter the serials into Seagate's site, you're good to go.
Be quick, it's running out soon. Good luck.

the 4TB drive IS NOT 7200 RPM and cheapest I have seen have been about $129

the 3TB drive IS 7200 RPM and I have got these for $99 (not bad at $33/TB)
Newegg sells the 3TB model in a Seagate ext. enclosure (that can be removed) for $99 and you can remove the drive from it.
You'll get a 3TB drive (cheap) and can put something else in the enclosure for an extra ext drive.

The 4TB is 5900rpm which actually gives you almost the same throughput as the 7200rpm model with lower power usage.

In our tests we found the 4TB Seagate HDD.15 perform surprisingly well in the group of other 7,200RPM hard drives, with the exception of the Hitachi 7K4000 that dominated the group. In mixed workloads the HDD.15 frequently fell into the middle of the pack and sequential read transfer performance came in about 15MB/s below the class leader.

Not too shabby - it beat out some 7200rpm drives while losing to others. It is much better than the 5400rpm drives in this regard. A good balance between speed and heat/energy use appears to have been found at 5900rpm.

I have 2 x 2TB 5900rpm drives (over 1 year now) and they are not bad at all.
You may have a point that the 5900rpm may have actually better throughput

I don't have a 4TB (yet)

But I do have several of the other SEAGATE drives

below are benchmarks on a new rig (running SATA iii)

 

SEAGATE 2TB 5900rpm ST2000DL003
READ  141.6 MB/s
WRITE 140.6 MB/s

 

Seagate 2TB 7200rpm ST2000DM001
READ  164.7 MB/s
WRITE 160.8 MB/s

 

SEAGATE 3TB 7200rpm ST3000DM001
READ  136.9 MB/s
WRITE 130.9 MB/s

 

also just for reference
Vertex 4 256GB SSD
READ  495.8 MB/s
WRITE 433.8 MB/s

You are posting specs for the old version of the 7200rpm with 5 platters of 600MB. That's two generations old technology. If you compare to a 1TB platter x 3 platter model the read and write average is about 160MB/sec and the max is 210MB/sec.

Not a big deal, but it's faster.

Cybersage is right in that the 5900rpm 4TB seagate is an excellent performer- it's faster than basically every low spindle speed drive out there. It's a good deal faster than a 5400rpm WD, or a 5400rpm Hitachi. So the difference between a 5900rpm 4TB and a 7200rpm is much less a big deal. If you want the extra size of the 4TB there is little reason to not get it.

When you compare a 3TB 7200rpm that read/write @ 160MB/sec to a 3 or 4TB 5400rpm that reads and writes at under 100MB/sec then you start to see a significant difference. Particularly if you run something like software raid (I use Flexraid) where the slower drive speed has a negative effect on your parity times, and adding another 1TB to read and write at a slower speed makes the process take twice as long. At that point you no longer can complete the task overnight - which is bothersome if you are trying to use the server and it's still half way through the task.

3TB are better for snapshot raid software raid set ups in media servers, as is faster HDD's.

As a desktop drive- 4TB is probably better.

Then again,

both would work for both so .... pick your poison.

I do think 5900rpm is a better compromise between spindle speed, performance, energy etc.... 5400rpm is not worth the trade off. I hate 5400rpm drive generally. The negatives of 5400rpm outweight the postives in desktop, HTPC, or media server applications. Only if you had a small NAS box with very limited air flow and cooling would I suggest something like a WD RED. Otherwise it's purely a waste of money. (opinion) It's slower, cost more- and it's not more reliable. The 3 year warranty is nice, but compare to a 2 year is it worth $30 more ? Not to me.

210MB/sec? Wow, how did you get that or just made it up in your mind?
I have over 10 3TB drives of 1TB platter x 3 platter model, and in many tests, I've never reached 180MB/s THAT LASTS MORE THAN 10 SECONDS not to say 210MB/sec with big files coppying.

First,

It's listed by mfg on product PDF sheet.

Second,

I've seen it in professional reviews.

Third,

I have experienced this myself.

Perhaps 210mb second is just a tad bit optimistic for a consistent expectation because it's a "max" spec - but, they certainly can do over 200/sec on the fastest part of platter.

That's really not important though. Far more important is the average speed rating which is 158mb/sec and much more indicative of what you might experience normally and consistently.

The latest line from Seagate are Desktop HDD.15

I'll supply a link to the 4TB model below
http://www.newegg.com/Product/Product.aspx?Item=22-178-338&Tpk=N82E16822178338


from the real world comments max read was closer to 160mb/s than 200mb/s

also since these drives are a premium in cost (compared to the barracuda models) I am not sure their worth it for a measly 20mb/s performance ?
I thought we were looking for deals here ?

 

Just trying to provide some actual useful info here

as far a best cost or $$/TB .. seems to be around $30-$33/TB

If you want better performance .. you'll pay more
