Newegg product listing N82E16822178306, Seagate Constellation ES.3 ST4000NM0023 boasts as solid drive. I haven't visited Seagate's High-end product line since their departure from the 5-year warranty of standard consumer lines several years back and only have had two 1 TB models recently for video editing / capture ( RAID 0). Since some time has passed from owning a high-end Seagate product, I welcomed the opportunity to see what Seagate has been putting under the hood lately on their Pro line of hardware, especially one in the price range near a half grand. Even with a high price there are just some inherent advantages that SAS offers over SATA and I occasionally prefer offloading to a SAS CPU than having local system boards handling data so seeing what SAS2 is in comparison to consumer lines and SATA will be interesting. (Wiki offers a good starting place for the casual beginner when looking at SAS vs SATA and determining if one or the other is a good choice for and particular utilization if you are new to SAS). With Seagate's Pro lines, I'm seeing a toe-to-toe stance when dealing with their competition and perhaps even a little extra toe stomping when it comes to exceeding longevity and outliving the problems their competitors have on their Pro lines. The drive is smooth, well put together and operating quietly and surprisingly cool, when compared to other Seagate drives and competing brands. If you see the notes in the "Other Thoughts" section, you should notice that this SAS2 drive falls in line with pretty much the performance of SATA III 6.0 drives. Keep in mind that SAS offers drive controller intelligence that SATA does not; also, SAS has the ability to monitor backplanes via sideband cable options on most mid to high level SAS cards. SATA more often mimics monitoring via software solutions weighing the system down more so than SAS hardware solutions. Another big factor that stands out is the little amount of heat that this drive puts off. True, I'm not running SQL Server or Oracle DB on the drive, but given the fact that I am moving a 40GB chunk of data all over the drive for an hour, and it's doesn't really get warm, helps draw the conclusion that Seagate's enterprise class drives run cooler and can take on more tedious encounters on a 24/7/365 basis. Further, not a single sector showed any defect, skip or error after a pounding 24 hour testing session

Improved overall performance of my Synology drive.

I am so glad to get my PC backed up again. I purchased 2 of these, one for my daughters Windows 10 and my Windows 7. The drivers loaded very quickly with no problems. Started Windows backup and a couple hours later it was complete.

good price for great product. I have bought several for multimedia storage.

Doing LLM training and needed to use a 35TB training file and 3TB validation file. Used 3 of these drives to create a RAID 0 drive with approx 54TB capacity. (this is on Ubuntu and formatted with XFS file system since usual EXT4 tops out at about 16TB file size.) Works great and much faster than a single drive would be due to the striping of RAID 0.

I have been using Allwaysync to copy data to this drive for a straight 24 hours (over 6 TB of data) and it is still running strong. I have this drive attached to a SATA2 slot currently instead of SATA3 as I didn't pay attention to where it was plugged in. Nevertheless, transfers started at 200 MBps for large files and over 6 TB in are still at 125 MBps.

Install is pretty simple and using is as easy as any other USB device

18tb of storage is great


I thought that I had received the wrong drive. Acutally I had the wrong cable. And I should have known better. Once I got the correct cable, the boards work.

Easy install Adds extra front IO Allowed me to keep my PCs ability to play DVDs while also adding a U.2 hotswap bay Comes with Sata adapter for the laptop dvd slot

4tb 3.725 usable Excellent deal goharddrive Customer service Quickly replies and Helpful Ran
