Seagate ES.3 Drives?

[parablooper]

I'm helping my friend build a computer, and I saw this HDD... apparently it's a new line, and the 128MB cache looks really nice.

It's got one good review that's informative, but who knows that could be someone from Seagate.

The Samsung spinpoint F3's became crap, the Barracudas became crap, and my next choice would have to be the WD Black FAEX.

Anyway, does anyone know about the Constellation? Does it have any problems?

It's not that new. It's been out for at least half a year.
It's an enterprise drive (like the rest of the constellation classed drives)

But will it blend?

With a sufficiently strong blender, sure.
I'd be seriously surprised if there was a problem with the drive: especially since it's an enterprise line.

The only hesitation I would have is to make sure you understand the difference between an enterprise class drive and a desktop class drive, as they treat error correction differently.

Desktop drives do error correction internally, but enterprise drives do it on the controller using ECC technology (requires ECC RAM and other things.)
Using enterprise drives in a desktop environemnt without ECC and a hardware controller can cause premature data corruption. Its a risk, but how serious is it?

I understanded something totally different than that.

3. Error Correction – Data Integrity One feature of an enterprise-class system is the implementation of “end-to-end” error detection. Enterprise class drives use ECC for data passing through drive memory and may use additional error detection methods for data transmitted within the drive electronics. Data that is transmitted from one end of the drive to the other with this system would be accompanied by some type of parity or checksum at every stage. This will allow for data transmission errors to be detected, and in some cases corrected or retransmitted. The form of this error detection and correction capability is usually proprietary to the drive vendor.
Desktop class drives deployed within subsystems do have error detection, but do not usually support end-to-end data protection that the Enterprise class drives implement. The reason for this is the lack of Error Correction Code (ECC) within the system memory or drive memory buffers.

It says that both have error detection, just that the Enterprise Hard Disk should be able to do that "end-to-end" error detection because ECC is available during all the route, while Desktop Hard Disk got ECC but only for internal errors. It does NOT say that Enterprise Hard Disk only relies on ECC support from the rest of the system.

The only real difference between the constellation and consumer models are validation, ERC, and a few bios tweaks.
Another interesting feature of the ES.3 is the 128MB cache.
Platter density is 1TB/platter just like the DM drives so performance is similar in most everything.
Performance wise the 1TB/platter seagates are my pick these days. I'm very happy with my two ST3000DM001 drives (which were an upgrade from two 1TB FAEX drives 500GB/platter).
The consumer drives are good for most everyone.
Unless you plan on buying an enterprise/soho oriented raid card (they can cost hundreds $$) to go with a few drives, the cost is not justified imo.
