Seagate 7200.12 HDD (Seagate ST31000528AS) or for perhaps 8-10% increase in price and performance, WD Caviar Black 1 TB (WD1002FAEX). For lower power requirements but lower performance, WDC 1 TB Green (WD10EARS). .
Between July 2010 to date, I have used three HDDs for my primary C: Seagate 1 TB 7200.12 (July-mid sep), Caviar Black 1 TB (45 days), and then Caviar Black 2 TB (from late Oct to present). I have found CB 1 TB to be faster than Seagate, but 2 TB Caviar Black is even appreciably faster than Caviar Black. In conventional HDD, 2 tb BLACK it may be be the fastest, alongwith Velociraptor and RE4. So if you can afford it, 2 TB Black, but at least a 1 TB Black. All 3 HDD now reside on my PC with 2 TB as the primary (of course with 4 partitions incl. C), 1 TB Black as multiple (three) partitions with acronis, etc backups (for faster restore), and Seagate 1 TB for movies, etc. Beyond Caviar Black is likely to be SSD territory.
your DG35EC has 4 sata ports, supports 4 SATA drives and 1 PATA devices...so yes. WD Blacks pretty much rule heavy I/O in mechanical drives and overall desktop performance, the 1TB Seagate 7200.12 is cheaper (like $50 local retailer Seagate OEM around here 1TB WDBlack around $100) and it's complex pattern performance is behind the WD Blacks, but the outer track transfer rates are similar now.
Look into the spinpoint F1 also, and I personally would stay away from seagate(not sure if they have fixed their problems with the 1TB drives they used to have).
Seagate has had no problems in my system. I do have 3 of 7200.12 (incl 1 as external) and 1 of 7200.11 (which was supposed to be problematic).
The Samsung F3 replaces the F1, and have been out for quite a while now. They are very fast, and I've heard they have the lowest failure rate. Just make sure when you purchase one, and this goes for Seagate and WD as well, that you get the proper performance model. Often computer places will just list them as Samsung 1tb, seagate 1tb etc, which is bad for the consumer because there are both ecogreen models and standard models. Things to check for on the model sticker is that there is no EG in the model name, and that its is a 7200RPM drive (the eco drives are more commonly 5400, but they may also be 7200!). The true Samsung performance 1tb drive model is the HD103SJ, which is an F3 drive. There are F4 performance drives out, but only in low capacities (such as 320gb), there is the F4 ecogreen models out though, such as the HD204UI. So, if you do go Samsung, get the HD103SJ, and ensure the manufacture date, about 2/3rds the way down the drive, is fairly recent (within 3 months). You don't want a drive that has been sitting around on the shelf for half a year or more! Like any drive, there may be slight chip changes (later models/versions), which can help with performance, and later firmware, even if the drive has the same model and revision number.
i would go with samsung disks all the way. i've had drives from different manufacturers, but my first samsung drive, a 200GB IDE disk, purchased 6.5 yrs ago still hasn't failed me, and SMART reports the drive to be in excellent condition. my second samsung 200GB IDE is just as perfect. my other 4 samsung disks,all S-ATA II , same story, running perfect over here 2x 200GB IDE SP2014N 80GB HD080HJ 500GB HD501LJ 640GB HD642JJ 1TB HD103UJ not only am i relying on SMART data but use two individual programs as well, HDSentinel and CrystalDiskInfo, both report perfect disks for me, samsung beats all in price and longevity so it's samsung disks for me. one thing tho, while Samsung disks operate very quietly, they tend to resonate in your pc case a bit more
