CONCLUSION

   Seagate lost the performance crown to HGST when they released their latest 7K4000 Ultrastar models but they made a strong come back (stronger than i had expected initially) with their latest Enterprise Capacity 3.5 V.3 (ES.3) drives since these are the fastest 7200RPM SATA III mechanical disk drives we've seen to date and according to our results the 175MB/s sustained speed claim by Seagate was not off. Naturally the more "optimized" SAS variants should easily outperform the SATA III ones (and we just begun testing on those as well) but Seagate doesn't really need to wait until we get those results in not when they already have the fastest enterprise class SATA III compatible HDD around. Honestly no matter how hard we try to think of something in the end there's nothing bad we can say about the Enterprise Capacity 3.5 V.3 4TB SATA III drives (aside that we prefer the Constellation ES.3 name a lot better) and so unless they start breaking down a lot faster than they should (reliable durability tests for an enterprise class HDD would take months to complete) these are the perfect choice for professionals and enterprise users alike.

   Price is perhaps the only downside one can find with enterprise class products such as the Enterprise Capacity 3.5 V.3 4TB SATA III hard disk drives by Seagate but since their target audience is neither casual users nor gamers i don't really think that's really a problem. So currently the Enterprise Capacity 3.5 V.3 4TB SATA III model (ST4000NM0033) retails for USD399.99 inside the USA (Amazon) and at around 360Euros inside the EU a price tag which is actually not as high as i was expecting it to be since it's roughly the same as that of the Constellation ES.2 3TB SATA III model on launch just a year ago. Well that's all folks, if you want the best SATA III compatible HDD in the market today you can't do better than the Enterprise Capacity 3.5 V.3 4TB SATA III and although i am very curious to see as to how the SAS models perform that doesn't mean we can deny giving our Platinum award away to the SATA III variant.
