Summary: The disk is perfect and stated new. However, my Readynas showed the power on hours for > 40,000. Strange ! Anyway, it was a good buy for only US$42 each. I bought 5 to replace all my old disks in the Readynas Net server.
Summary: I got these hard drives because my 2 TB drives were not working well with my external hard drive back up software. I figured out that the byte sector size was the problem with the Seagate Backup Plus. After long research and hundreds of customer reviews, I figured out the best way to backup presently was to stay with the 512 byte sector for now, until the "showboat" has stopped and the manufactures have ironed out all the issues surrounding the 4K compatibilities.
Summary: Bought a refurbished HP as back for other computers. Drive(750 gb)started acting weird with mouse doing crazy stuff and finally the drive just sat there, trying to reboot but in a never ending boot process. Have everything backed up, only loss is time and $$$ for a new WD drive. Have used lots of Seagate, et al in the past. Think it's the luck of the draw but decided I would prefer WD as a replacement. Why take a chance.
Summary: I've used quite a few of these drives, all of an OEM variety (so linked firmware may not help this, for what it's worth), and they've all been quite reliable, and fast enough for the purposes needed. However, and this might be part of the firmware issues, I plug these into USB2 docks on occasion, and under no circumstance will they write faster than 7MB/second. It's to the point where it's painful to use the drives in this way!
Summary: These drives I bought to go into a 4 disk raid array in a Synology cs-407. These drives arrived quickly and replacement went without a hitch. At the time of purchase they were $99 back in May 2012. Now they are down to $67 and are a bargain at that price. They are quiet, and did not have any of the firmware issues described in these reviews. It may have been an earlier batch, but I have not experienced any problems and they have been pretty much 24/7 operation.
Summary: This hard drive had sector errors when first initialized and they increased quickly over the first week of use. Pulled the drive and replaced it with a Western Digital hard drive that showed zero sector or ATA problems when initialized and which still shows as being in perfect health. Lots of reported problems with this drive but I bought it to use in a RAID NAS that had three other Seagate Barracuda hard drives.
Summary: This is a solid drive for enterprise level usage (probably not worth the cost for most personal users). The TV station I work for uses these on all our NAS servers, and we have a failure rate of about 1 a year out of the entire lot (about 40 HDs), which is impressive considering how many we use at once. However, I was shocked by the Amazon price. Do yourself a service and pay the correct price: [...
