Seagate is the patriarch; the Apple of HDD territory. I’m not extremely time constrained by deadlines, so I can live without a SSD… until the price market normalizes.
If you’re going to be “hitting” on your HDs continuously… buy an Enterprise model, instead; they’re built tougher; for server workloads.
A WORD TO THE WISE: Invest in a UPC Power Protector, and a good disk utility program… I’ve NEVER had a HDD die on me!… Like your car, “Take CARE of IT… and it WILL take CARE of YOU!”

Seagates are great, and ALL the capacity you paid for is there. Really!
Your mileage may vary, but over the past 25+ years, I have found Seagate drives to be much more reliable than Western Digitals, and Maxtors aren't even in the race.
To compute available disk space, you must know the math behind it. In decimal, 1 terabyte would be 1,000,000,000,000. In binary, it would be 2^40, or 1,099,511,627,776. A 1.5TB drive has 1,500,000,000,000 bytes (plus a few more). Divide that by 2^40, and you will get about 1.36TB, which is the capacity expressed in binary.
To convert between decimal and binary for a drive measured in gigabytes, use 2^30; for megabytes, use 2^20; for kilobytes, use 2^10 (which is 1024, commonly called 1 kilobyte, or 1000 decimal). In that last case, the difference is only 24 per kilobyte, but by the time you get up into terabytes, the difference is over 99.5 billion, and people start to wonder where it all went!
The label on your Seagate drive claims 1500Gbytes. That is in decimal. In binary, that converts to about 1.36TB. So, you have not been cheated out of any capacity; it's simply a matter of the method of notation.
To see the exact numbers for your drive, open Windows Explorer (My Computer), right-click on your drive, click Properties. You will see its capacity in decimal and in binary.
To crank through those numbers using my values above, you can use the Windows calculator. In XP, click Start Run. In Win7, just click Start. Enter CALC. Click View Scientific to access the x-to-the-y key (2 keys left of the 4 key). Tap 2 (for binary), then x-to-the-y, then 40 (for tera); press Enter. The rest is simple arithmetic, and should reveal the mysteries to you.
If any of that is unclear, just ask most any teenager with glasses to help. [:-)Read full review

Not the fastest drive, but a good value for the price.
I needed a larger capacity replacement drive for an aging computer, and this Seagate drive fit the bill perfectly. At under $0.07/GB, the value was amazing. The drive is fairly quiet and fast enough.
First, the capacity. Most of the 2TB+ drives I found were SATA 3.0, and my motherboard was only 2.0. While this wasn't a big deal, I couldn't justify the extra price for higher performance I wasn't going to see on my system. So, among SATA 2 drives, this was one of the biggest. 5/5 on that.
Second, the price. If you search around, you can find these drives at just over 6 cents per gigabyte at the time of this writing. That's a great price range, better than the smaller drives and most of the larger ones. 5/5 on that.
Now, performance. The drive is faster than the one I replaced, upping my Windows Experience score from 5.2 to 5.9 and feeling faster in response when copying large files and extracting archives. Still, it's nothing close to an SSD, and even pales compared to SATA 3 drives, or the Raptors. It also takes an extra second or two to be recognized by my BIOS, slowing down the boot time. 3/5 on performance.
Drive noise is an issue for some people like me. This drive is pretty quite generally, but it did make a bit of noise when the swap file was used heavily. I didn't notice any vibration at all. 4/5 on that.
So, overall, this is a good drive if you're short on cash and need an upgrade. If you've got the extra money, I would suggest going up to the newer 3.0 drives.Read full review

Reliable disk, requires fan cooling, has severe write performance issues.
Traditionally a very reliable disk, this model holds up well under heavy use. It doesn't run too hot when in a fan-vented case. I would not recommend this disk for fanless enclosures.
Great for backing up data since write performance is very poor under certain circumstances. Read performance is very good.
BEWARE: This disk does not have rotational vibration correction. When used in systems/enclosures that produce significant vibration the write speed of the disk may be seriously impacted. In some instances performance has been reduced to 5MB/s and slower. DO NOT USE THIS DISK FOR any high performance applications that perform high write I/O (IE: Database, video editing/design, etc).

I love this product and would buy another when the time comes.
I bought this product just for backups and did not want to pay too much for it so I bought a used one. So far so good, I put this HD into an external drive box on an e-sata connection so others could back up to it as well. It has worked out well for me as most of you know buying used products can be tricky, this one was well worth the money.
when buying new or used on e-bay make sure you have a set spending limit and do not go over it no matter what. It may take a little longer to get what you are after, but as you learn in fishing patience is a virtue.
