Seagate IronWolf 8Tb NAS Internal Hard Drive HDD – 3.5 Inch SATA 6GB/S 7200 RPM 256MB Cache for Raid Network Attached Storage (ST8000VN0022),Silver

Pros:- High Capacity.- Quiet compared with other 7200 rpm NAS Drives (HGST).- Seagate Tools provides an excellent suite of testing and drive monitoring software to test drives before Installation.- Read and Write Speed are very Good for a HDD.- 256MB Cache which is 2X the Cache on WD RED or HGST NAS Drives.- 3 Year Warranty.- Drives are HEAVY with a lot of Thermal Mass compared to other NAS Drives.- Low vibration.- Drives run Cool (compared to other similar capacity NAS Drives).- No Drive Failures in 10 months of 24/7 use.Cons:- Cost per Terrabyte is still higher than for IronWolf 4TB NAS Drives.I have 15 of these Seagate IronWolf 8TB NAS drives operating in RAID and non-RAID configurations. Some of the drives have been operationg for 10 months of 24/7 Data Server and Media Server conditions. So far, I have had no failures. I test each drive before installing it in the servers by doing a full format of the disc, doing short and long self tests in Seagate Tools, updating the firmware to the latest versions available, and generally running the drives through the entire gamut of tests in the Seagate Tools menu. The testing suite takes more than 48 hours to complete but, I would rather spend the time up front to ensure the drives are not going to fail from infant mortality and there are no bad portions of the drives before spending more than 24 hours to load data unto the drive and have it fail.So far, I am very satisfied with these Seagate IronWolf Drives compared to NAS Drives from HGST and WD. The HGST drives are noisy and I am concerned that there will be head crashes. After having the same problem with 8 of these drives, I realized that it was just a characteristic of the HGST drives. I still don't like it. The WD Red 8TB NAS drives are slower to read and write and are loud compared to the IronWolf drives. I also prefer the Seagate Tools maintenance suite over the one for WD.I watch for the sales on the IronWolf NAS drives and save 20% on the price. This adds up when ordering multiple drives.Other Comments:I have started buying the IronWolf 10TB drives. The outer case must be made from Magnesium or the drive spindles and platters must be made from some ultra-light material and different design. The 10TB drives are quite a bit lighter than the 8TB drives with the same outer dimensions. The 10TB drives are also quiet and low vibration. So far, after 3 months, the 10TB drives are performing good also. I recommend the Seagate IronWolf NAS Drives.Disclaimer: I have no relationship with Seagate or any other drive manufacturer. Every one of the drives I own have been purchased with my own money I have no incentive to give a good review other than the fact that I like the product and it performs to my expectations.

I have six of these in my NAS, and it runs 24/7. The reliability is outstanding. Over the course of 7 1/2 years I only had 1 drive fail on me, and that was after running continually for 7 years. To only have 1 failure after 65,000 hours of continual use is pretty amazing. Since I was running RAID, not a single byte of data was lost. At the rate we tend to upgrade technology, it is wonderful to know these drives and the QNAP NAS still exceeds my expectations today.

I bought 4 of these for a NAS device. Worked fine at first, then gradually began running warmer and warmer. The drives are specifically labelled as NAS drives and came with a 3-year warranty. At 3 years and 10 months all 4 drives began throwing SMART errors of "Pre-Fail" and "Old_age". Dismal read / write times and rapidly growing bad sector counts. I've been around long enough to know that Pre-fail and Old_age don't necessarily mean much, but the high, and increasingly higher temps along with growing bad sector counts definitely do. When I first installed them, these drives had great performance, low temps, and great SMART stats. So much so, that I added a 5th Seagate NAS drive later on. Now, even that one has failed after only a few months (I'll warranty it out, but I honestly won't be comfortable using the replacement). So many reviewers speak highly of Seagate drives, but after 20 years of buying drives from WD, Seagate, and yes, even some others, I can honestly say that I would probably never buy another Seagate drive. None of these 4 Seagate drives were even close to their MTBF limits. There's simply no legitimate reason for the failures except that quality control sucks and Seagate is shipping poorer quality products than ever before. Too bad. Was once a really great company with really excellent products. When you spend almost a thousand dollars on hard drives, I believe you have every right to voice your upset when they all fail shortly after the warranty expires. So.... here it is.
