THICKER THAN 12MM I checked all the measurements of my laptop and thise 12mm drive. It's bigger than 12mm and does not fit in a 12mm laptop slot or even a 12mm external case I bought for it. 1Not new! Buyer beware! These drives are not new! We purchased 5 of these (from TechPro Systems) and tested the first 4.The least "Power On Hours" among the four was 19938! (> 830 days, or well over 2 years!).Buyer beware! 1See the SMART information. I am totally dissatisfied I bought 10 disks from Aeon Micro Inc. All of them were used. They had been running for 6 years. See the SMART information. I am totally dissatisfied.Be aware when you buy used enterprise disks. Even though they described as new... might not be true. 1Used drive sold as new! My bad - didnt pay attention and I am sure I received a used drive. 3Buyer beware... there may be some deception regarding the condition of these drives. As several other buyers have indicated, I too was very disappointed when I purchased this drive on the advertised pretense that it was new . I purchased one from the vendor iTech Sourcing and it was listed as new in every step of the process, including the confirmation email they sent after I submitted the order. When the item arrived, I immediately connected it to my computer and checked the SMART diagnostics. The drive had just under 20,000 hours of use. The power on cycles showed 6, which implied the drive had been turned on and run almost constantly for over 2 years. If you have recently bought one of these, please check the SMART diagnostics. You may have gotten used equipment. 12.5" Constellation series drive 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. 5Definitely NOT new and has SMART errors!!! Ordered 2 drives one has over 54000 hours on it and a bunch of SMART errors. The other has over 24000 hours on it. This one was more expensive so I had hoped for better but yet another Amazon fake product description. 1Works on my R710 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! 5Seagate 1TB It's a HDD, works well and reliable. 5What a disappointment. I believe this is a 15 mm drive where most are 9mm or under.. You'll have a hard time fitting this drive into any device (Laptop, Drive Enclosure, and even small form factor PCs). The cost for the drive was low, so I thought it was a good investment. Since it would not fit in any enclosures that I already owned, I purchased one especially for this drive. When the new enclosure finally arrived, I installed the drive and discovered that the drive didn't even work. I sent it back for a refund and purchased a thin 7mm drive, which worked in all my equipment. What a disappointment. 2
