Seagate Exos X16 ST10000NM002G 10TB 7200 RPM 256MB Cache SAS 12Gb/s 3.5" Hard Drives, 512E/4KN

Overall Review: Not much to say other than it came as expected and is as described. Random 3x overwrite via the SAS controller was done within a day and a read/write surface scan through the OS was pretty quick. I didn't stick around and watch it but it was done by morning. Drive has now been promoted to storing duplicated data. If you don't know the difference between Serial ATA (SATA) and Serial Attached SCSI (SAS) drives, you probably shouldn't pick one up or you'll be surprised like a previous reviewer. SAS controllers are backward compatible with SATA disks; SATA controllers don't know squat about SAS and to make sure people ignorant of the difference don't plug a SAS disk into a SATA cable or NAS backplane the connectors are keyed differently.

Pros: - Fast drives - No DOA's - High Capacity means fewer needed for our purpose - SAS3

Cons: - Drives I got had 3 out of 12 that had sizable dents in them, which were there before we unwrapped them from their static packs - Shipping box they were in was questionable in terms of quality and looked reused at one point

Overall Review: All drives worked, but the dents were definitely from mishandling somewhere. Otherwise would buy (and likely will buy) again. Exos drives are definitely some of the nicer enterprise drives, so would recommend, just maybe with better packing .

Pros: Great overall throughput. Amazing SATA see & random write speeds!

Cons: None

Overall Review: Need big and fast in a HDD? This is the one!

Pros: None

Cons: There is a solid bulge of plastic between the data and power connections. The connection in the QNAP bay requires an open space between the data and power connections. Therefore, the drive does not fit into the bay. The far right picture on the Newegg website incorrectly shows a space between power and data connections.

Overall Review: Not sure why Seagate would change the design of the connections? Intentionally creating compatibility problems?

Cons: i bought this 16tb drive to replace a smaller seagate, but the plug is all wrong. what the heck is sas? i need sata. now i have to send it back!

Overall Review: i thought a seagate hdd was a hdd, i don't know sas from sata. you better make sure.

Pros: I ordered this SAS drive, but my computer has only SATA connectors.

Cons: I spent 14 months piddling to try to get it to work. I was dreading the presumed work to make it work. Mostly the time was just me procrastinating. I didn't "need" the HD. I ordered the adapter which took a month of Sundays to arrive from China, but then it still wouldn't work. Turned the cable was bad. Further procrastination. I finally found that either the adapter from china is also bad or the drive is dead. Regardless of my ridiculous tardiness Manpreet at Seagate is sending me the right HD for the cost of shipping only!!!!

Overall Review: I've always had excellent luck with Seagate HDs. After procrastinating for 14 months, this is like a getting Christmas present they were so helpful!!!
