Careful when ordering this!
By Christian Barilone on August 22, 2012
Size: 1 TB
This is listed under personal, laptop drives category but upon researchign it further I found it to be for servers only. I've attached a link to the Seagate site for it. The thickness of the drive is 12.5 mm, which won't fit the typicaly thickness allowed by laptops of 9.5 mm.

Works on my R710
By Gene Jone on September 20, 2012
Size: 1 TB Verified Purchase
I have a DELL R710 that already has three 15k SAS drives and wanted more storage that didn't need to be as fast.

With five bays available I ordered (5 Pack)2.5" SAS/SATA Hard Drive Tray Caddy for Dell G176J PowerEdge R710 T410 T610 T710 R815 and then ordered five of these drives. Attached the drive to the tray caddy (NOTE: screw the drive where it indicates SAS not SATAu) and put them in the server while it was powered down. I booted up, went into the Perc Raid controller, saw the drives and added the new RAID5.

After initialization and a reboot, the drives were seen by vSphere ESXi 5.0 U1 and I mounted it as a new datastore. Since there were 5 drives, my IOPs are higher than just doing three and disk latency is minimal. In real world applications, I have 5 Windows 2008 R2 VMs running on them and three Virtual desktops and no complaints from users.

So five stars and two thumbs up!

2.5" Constellation series drive
By W. Scott Jarriel on November 19, 2012
Size: 1 TB Verified Purchase
The Seagate Constellation series drives are their enterprise level drives. Different firmware from the consurmer drives, and much better reliability. Also, these drives are consistantly compatible with all RAID levels, in pretty much any system. I am using them in QNAP NAS boxes. These are not the highest capacity drives in the series (they have 2GB drives that are 3.5" size), but the smaller drives have a lot more room around them for cooling, when mounted into tight NAS box configurations. And cooling is everything to the drive's life span. You get what you pay for with these little drives.

Work great in HP G6 DL360s
By Ace Metrix on April 22, 2014
Size: 1 TB Verified Purchase
I tried a number of drives with HP servers and keep coming back to these. They work. If you have installed HP servers and attempted to use "non factory" drives as replacements then this should be music to your ears. The servers don't complain. The performance is good enough and they are as reliable as another other spindled disk I have used.

By Darrell Cochran on April 2, 2015
Size: 250 GB Verified Purchase
I try to clone it through my USB port as I have done in the past to install my OS. It loaded the drivers but would not show the drive on my PC to format it. I installed the drive in my PC and still no luck!!!!. Just a small boat anchor now.

I am very pleased with this hard drive. Just what I know and I love.
By Pablo Zurita on May 19, 2014
Size: 250 GB Verified Purchase
It is a compact, relatively inexpensive but ideal for forming a RAID 0/1 on a PC . I will buy another in the near future.

Good buy.
By Dennis Lamielle on May 15, 2014
Size: 250 GB Verified Purchase
A great hard drive for the money. I didn't need anything near 1 TB or even 500 GB. This was perfect.

Completely useless and a waste of space
By Paul Kain on October 7, 2015
Size: 500 GB Verified Purchase
This hard drive does not fit in my laptop because its 12.5mm thickness instead of 9.5mm thickness. My laptop requires the 9.5mm thickness. This is a enterprise level hard drive that fits in a server and not a laptop. This should have been listed with the 12.5mm thickness and it was not. If it had been correctly listed, I would not have purchased this hard drive wasting my time and money. This hard drive is completely useless to me.
