Bought 8 of these 10TB for a synology NAS 1 was bad at install and two have failed in the last 2.5 years. 3 stars because the warranty covered the replacement, but the hassle of returning, peace of mind, etc. is disappointing in a supposed enterprise class HD. Thank god for raid 6.

FAST! over 188MB/s sustained r/w on SATA II 3.0Gb/s Excellent choice for a Mac Pro for a fat, fast striped RAID 0/5, or as a Time Machine/ clone/ storage drive. Plenty of performance in single-drive for general use for HD movie/video/audio storage and playback without delays, stops or stutters. I got it on sale and don't regret it.

Factory configuration is for Power-up in standby (PUIS) which is incompatible with my Synology DS916+. To use with Synology; you have to find the right utility on Seagates' web site... boot the drive in a computer... and the run a commandline utility to turn off PUIS. Doing that will disable this feature and allow you to use the drive in your NAS.

I bought a few of these for my new Synology NAS, I've gotta say these are BEEFY! So far, no problems here whatsoever. They all worked right out of the box as expected and are quite fast, though I don't have exact specs. I will say I did a lot of research beforehand and my brother in law (who is very competent in the ways of IT tech) had nothing but good things to say about these. I'm glad I listened to his advice!
It is fast, quiet and has an amazing capacity. While I will populate a NAS in the near future it has been a wonderful drive to organize and backup my pictures. I had several 4T drives and started having to spread my pictures across more than one of them. Now they are all on one drive with a backup that is taken off site.
Liked it so much that I purchased a SECOND one. Lot of room to save my many files, especially photos and videos. Purchase was especially good, as the price has come down since it was initially introduced. Recommended!
