Pros: Tested drive several times and had no SMART errors nor errors of any other kind. Drive was packaged in a small box with the appropriate hard drive bubble wrap to keep it from being damaged in shipping. All went well.

Cons: Not a regular 7200 RPM drive, so if you're looking for a faster drive, this isn't for you.

Overall Review: I'll continue to test this drive and did get the extended warranty in case it fails down the road.

Pros: -Lots of storage for not that much $ -For the single day that all 4 drives were working I had 150 MB/s write and 370 MB/s read in RAID 10

Cons: -Very loud. If your system is setting on your desk, I wouldn't recommend it. -I order 4, 1 died after 24 hours. Click of death.

Overall Review: I got these because they were on sale and had similar performance to the drives that I was originally looking at. If I were to do it over I would have probably spent the extra $100 to get better drives.

Pros: Decided to get this so i could move away from using externals and free up some USB ports. So far its working just fine, Got a speed of 35-40 MBs Perfect for storing all my games, Movies and TV shows. Good price, Fast shipping.

Cons: Not really a con for the HD but i couldn't figure out why the HD wasnt showing up with the rest of my HD, I didnt realize or just forgot i had to go into device manager and do a quick little set up.

Overall Review: If your looking for something good to hold lots of files this is a great HD.

Pros: It has been in constant use for 4 months and no issues yet

Cons: None so far

Overall Review: This is my first Seagate drive in a long time and so far I like it, no negatives yet.

Pros: It is what it is, a 4TB hard drive; both of mine worked properly out of the box, nothing unusual to report.

Cons: I agree with a previous reviewer's comments about how hard it is to discover this drive's rotational speed; looked everywhere, had to buy one to find out. Alas, it's 5980 RPM...

Overall Review: Assuming people know it's *not* a 7200RPM drive, I'd suggest it.

Pros: Unfortunately none.

Cons: Right from the start this drive was a problem. Gave me issues right out of the box creating a partition and I have done many drives before. Took a second attempt before it succeeded. Copied all my data over to this drive as it was a replacement for a 3TB drive that was almost full. Just out of the 30-return window the drive died completely. Got a SATA error on the boot screen and halted my computer. From that point on Windows could no longer see the drive. Ran the Seagate Drive Repair software and it failed the test.

Overall Review: Currently waiting for a replacement from Seagate but they tell me they don't have any in stock. Plus it's now costing me extra in shipping.

Pros: Worked fine for 7 months.

Cons: It died after 7 months. Not eligible for return.

Overall Review: Would not recommend. Bought 3 Seagate 1T drives since 2014. All died without warning.

Pros: Very Quiet in operation. NO detectable vibration in these HDD ( my drive sleds use rubber isolation dampeners to mount the HDD). Good over all speed during the copy test, average about 120 MB. Over all temp remained from 27 C to under 34 C during migration of 2 TB of data. (3 hr test). Speed at 5980 RPM its adequate for my purpose but not really recommended for GAMING, a SSD or a 10 K RPM physical drive is better in that application. Files that were migrated were larger than what one would expect on a normal computer. These Seagate BarraCuda ST4000DM005 4TB HDD now serve as my newer VOD repository drives. And the reported DATA speeds were much better that the current situation of HDD's that I am using. Now only Time will Tell as to how well these work. Over all impression is a positive result on what I received, the results of the HDD performance tests and how they were shipped. Would I recommend them ... Yes... as from my current experience they meet my needs and would be adequate for Home Server or Direct Attached Storage . ( more on this below) I would also recommend them for Media Center use as they appear to be almost as quiet as my SAMSUNG F4EG 2 TB HDD Update 9/27/17 - Seagate ST4000DM005 Ok some time has passed and I have been using these Seagates for storage for Video files. I have had to make them BASIC disks in mmcc for W7. I also purchased a WD40EZRZ 4TB Hdd and have compared them. Price at time of purchase was about the same. As to differences between them not much except they WD was 2 degrees Hotter when doing copy / writes between a Seagate when in a USB cradle.

Cons: These are not really Cons but have to say something..call then gripes! Price on these have been relative high but it appears that since Manufactures have started to make larger 6TB, 8TB, and 10TB HDD that these 4 TB units should come down, Would be nice if the price point was below $99. In WINBLOWS 7 ... these cant be Partitioned and formatted above 2 TB which leaves you a segment of the HDD as not usable. This is a problem w Windblows. Have not tested this on 8 or 10 yet. TO use the entire HDD in WINBLOWS 7; you have to create a GPT partition which then can be formatted to 3.8 TB. You must remember that formatting a drive takes away space from the total RAW capacity of a HDD. This issue of partition is not a fault of the Seagate BarraCuda ST4000DM005 4TB drive but rooted in DOS and Windows (op's I said it). They are non SAMSUNG HDD's .. but it appears that since Seagate acquired Samsung's HDD division that Seagate has finally used the technology that SAMSUNG had in the F4EG 2TB HDD's, I have about 8 2TB Sammie's in production and all have been working for 7 years. Odd occurrence if your source HDD is a Low Power HDD ( RPM below 6k ) and your coping to this drive, the data transfer in MB/sec is lower, This is to be expected since Rotational Speed (RPM) and the amount of cache on the source drive contributes to the throughput of the receiving HDD, In my situation I used several HDD from 2 TB Samsung and 1.5 TB Seagate Barracuda's which have a higher RPM and data transfer was higher on the 1.5 TB Seagates (7200 rpm). This aspect impressed me no doubt due to the larger cache on the Seagate BarraCuda ST4000DM005 4TB HDD allowing it to receive data at a faster rate (there is a cache difference in the sending HDD and the newer HDD which can account for some of this). Smaller cache to larger cache can account for RPM mismatches as in my case the 7200 RPM to the 5980 RPM HDD. Update 9/27/17 - Seagate ST4000DM005 Ok I did have one issue that concerned me .. one of the Seagates Had an issue when trying to mount a Seagate into a Rosewill USB 2.0 caddy - this caddy is an older one. The Seagate when mounted had some issues w the OS trying to read the HDD. I then removed it and attached it to the W7 system via a SATA cable and cold booted the PC. The OS complained about errors on that drive and wanted to fix them. (CHKDSK) ! Which it did found a lot of files that were not working I (broken links). This ran for over an hour (lots of VID files) and the data was ALL recovered when finished and OS mounted the HDD as a volume ( on SATA port). Ran tests to no avail. SMART tests all passed. I believe that the Rosewill Caddy capacity limit does not support 4TB HDD as none of my 2TB Hdd have ever had this problem. These usb 2 units are old. I have replaced the external USB to an inateck USB external dual dock module w USB3. And the Seagate's and the WD have had no issues w this enclosure to date.

Overall Review: Packaging: All 4 HDD that were ordered came in a NewEgg box w 4 individual box's inside that box. This shipping box was the right size to contain all 4 of the HDD box's inside. The only added packaging was some puff pack on the top to fill the space. I thing NewEgg has finally gotten the shipping of HDD right. But I would suggest some Puff back be used on the bottom of the shipping box before inserting the other box's and then a sheet of Puff pack on the top. Also inside each HDD box was a rather unique way of packaging the HDD in its static bag. I did not see the cardboard end caps but instead a pressurized plastic enclosure that opened like a Hard Box of cigarette's where the lid overlaps the top of the HDD and you slide the HDD out. And I do mean slide they are very snug in these pressurized box's. These I am keeping for future storage, I am impressed with these "Air Bags". One aspect of these bags is that each chamber of air is separate from the other chamber and if one or more are deflated then the HDD has had some hard knocks before you got it. Who ever designed these should get a GOLD Star IMHO. Tests: I ran tests on each drive with HDD Tune as well as HD Sentinel .. ran long tests on all 4 HDD and all passed. All of the results were not identical there was some fluctuation in the values but not any to cause me to RMA them. We are talking values of under 1 to 2 % of the total. Also I monitor the S.M.A.R.T tests to see if any issues arise which none did. Copy test to drives was over 3 to 4 hours long and monitored temps and performance. Temps were withing what I expected and the data transfer didn't slow down which is great. Now Seagate states that these HDD units are "Best-Fit Applications - Desktop or all-in-one PCs - Home servers - Entry-level direct-attached storage devices (DAS)" My concern is that most external enclosures for DAS or Home Servers are lacking in cooling capacity as they are trying to make the box as small as possible which limits air circulation. The question of air flow is critical for HDD to last. As these ST4000DM005's have a lower spin rate and in my case they were inserted into drive bays that were directly cross cooled by a 120 MM fan that the reported temps were well within acceptable ranges. When transferring data from the 1.5 Seagate Barracuda the temps on that HDD went up about 10 degrees to where HD Sentinel alerted me of this condition ( 47 degrees C). And the Seagate BarraCuda ST4000DM005 was only up to 35 C. Again cooling is always a concern to drive health. Now if they stick around I would be purchasing more of these. But in final review if they last then the get a BIG THUMBS UP...and like I said So Far So Good. If you like this give it a thumbs up .... UPDATE. 9/27/17 - Seagate ST4000DM005 I have owned 4 these for about 4 months now ... still looking at purchasing more. But price needs to break the century mark on the negative side. Not sure why so many people report issues w these HDD. Granted they can be problematic on a First time install but if your system is somewhat NEW and and has UEFI bios you should have no issues. Now I did have to set the up as a GPT volume first time as the HDD exceeds the 2TB boundary ( this well all know) but I then converted it to BASIC in W7. This may not be a problem in W10. But can't tell as I only have one system on W10 a HP Laptop. If your having issues Now as to that WD40EZRZ - that's a horse of a different color.. I an not an employee of Seagate, NewEgg, or WD and I did not receive these as promotional "gimmie's" which would have been nice ... LOL but just retired and living on fixed income.
