Caution on Seagate drives lifespan,
I have bought/sold Seagate drives for 25 years. I have recommended Seagate for most of those years. I am in the storage business and have a lot of direct experience with drives.
The problem I am discovering is a greatly reduced reliability in Seagate 1.5 and 2TB disks. I currently have about a dozen 2TB Seagates in active use. 7 of them are beginning to fail, in under 4,000 hours of use. These are disks which were burned in by certifying them for about 3 days with an intensive read/write pattern, to eliminate early failure disks. In the general disk population, I have also seen a high failure rate. This is unacceptable.
Google performed a study using over 100,000 disks a few years back. Google found statistical differences in failure rates between manufacturers, that they did not publish. They also noted that “enterprise” drives did not result in longer lifespans. They found NO correlation between heavy duty or light duty use in failure. What Google did report was that a handful of SMART parameters could be used to predict drives that would soon fail. Among these are reallocated sectors. Once a drive begins reallocating, they generally fail within 6 months or less. There are SMART utilities which are starting to implement this knowledge and alerting users to predicted failures.
For a long time, Seagate was the premium brand of hard drives, along with Hitachi. They may still be. However, this failure rate on the 1.5 and 2TB drives, in addition to the major firmware flaw on the 1.5TB drives (Many customers lost data on the 1.5TB drives, where drives suddenly failed from a firmware flaw), makes me very cautious on Seagate now.
I am recommending Hitachi for now, they will cost a little more, but until more data is in, be alert if Seagates are installed and perhaps avoid them in servers and mission critical installations. I have no data yet on the 3TB drives.

|Great Drive, Great Performance, But……Watch out……,
In my server, I have 6 2TB drives installed, in 3 sets of RAID 1 configuration. I wanted to replace 2 of the old drives with these ones.
I purchased and installed and immediately noticed that on Power ON, it would take few seconds for my Server to reach POST screen, which is surprising. I have 850W power supply, and 2 video cards, but still have plenty of spare power capacity left.
So I disconnected these 2 new drives, and guess what, system immediately comes to POST on power up.
I did some research and found that this model drives draws more power on start up. Once started, they behave nicely, just the initial power ON current draw is higher than other drives. Long story short, I swapped the drives from my NAS enclosure to my server and installed these 2 drives in my NAS.
PROS:
1) whopping 64MB cache….!!!!
2) Fast SATA 6Gb/s interface
3) Sustained high data transfer rate, (recreating RAID was much faster on these drives)
4) Light weight since it has only 3 platters
5) Runs cool, even with sustained data in/out operation
6) Quiet, even when transferring, reading/writing data
7) Cheap
CONS:
1) Higher start-up current draw
2) 4K sector size, which may or may not be a problem for you, depending on your application, OS etc.
3) Only 3 year warranty

|Terrific, fast, very quiet,
I purchased four of these to replace four 500gb SATA 2 drives by the same manufacturer in a Netgear ReadyNAS NV+ machine. While I cannot attest to the new SATA 3 (6 gb/sec) speeds (the ReadyNAS is SATA 2), the new firmware from Netgear required me to do a factory reset on the device, and upon boot it recognized the new 4k format being used by this drive. After the drives were striped and the volume redundant, I was able to copy about a terabyte of data off my local machine in about 12 hours (with breaks in between).
The new drives run cooler than the old 500’s, are amazingly quiet, and fast– so far I’m quite impressed with their performance (especially with the 64mb cache). While I haven’t seen their long-term viability yet, I’m pleasantly surprised by how well they work.
