Seagate ST4000NM0025 Enterprise Capacity 3.5 4TB SAS 6Gb/s 512n

Ordered 4 of these bad boys during the 11.11 sale. Disks were well packed and shipped individually. All disks were received within a week without any physical damage.Warranty registration was done without issue with Seagate but note the warranty period was only 18 months instead of the advertised 2 years. Not a big deal for me, given that these cost a fraction of the MSRP.Was initially concerned with the potential noise from these EXOS as compared to their Ironwolf counterpart. I have 4 of these running in a NAS and the sound is bearly audible under rest conditions. Under more intense write mode, you can hear the motors spinning but again the sound is louder but definitely not noisy.

*** Update 10/16/20 *** Bought another of these drives after the first being so good. I was sent an OEM drive from Platinum Micro Inc. No mention of OEM HDD being sold for the same price as retail. Don't do it unless you trust Platinum Micro to handle any issues you may have over the years, firmware, noise, failure etc... Yeah right. I've been working IT since the 90's and have rarely seen a reseller honor OEM warranty except for the big names like Dell, HP etc... Marketplace sellers dishing out OEMs leave the consumer out in the weeds after taking your wallet. Sure you save a few bucks, but it isn't worth it for zero warranty on relatively failure prone devices. Note there is nothing that states you are buying an OEM drive. Also all I did was re-buy from cart ... More*** Update 10/16/20 *** Bought another of these drives after the first being so good. I was sent an OEM drive from Platinum Micro Inc.

I'll be buying these for a while now.

Drive worked well for a month.

Drive arrived whole and worked right away. Very happy with transfer speeds. The drive is the noisiest one I have ever owned but the noise seems normal, not like the drive is going to fail. Given the price, warranty, capacity and speed I will put up with a little extra noise. After about a month of service I checked the drive with Seagate software. The SMART data indicated the drive had issues. I ran the long fix and the drive failed completely. Went through an RMA with Seagate, waited two weeks for the replacement from California but it was DOA. System wouldn't boot and the motherboard beeps when the drive is connected. Contacted Seagate again and this time they are going to pay the shipping both ways and they are going to ship a new product rather than a ... MoreDrive arrived whole and worked right away.

RMA with Seagate is a long and arduous experience. I really am beginning to hate this drive. I have 4 other Seagate NAS drives which have been spinning for between 5 and 7 years with no issues at all. This one has a 5 year warranty so from the looks of things I will be an expert at the Seagate warranty process by the time this is over.

Fast and huge

I use two similar drives as part of my backup process. My other is the slightly older "X10 Hyperscale" version, and it whines and clicks much more loudly than this one as it spins up and seeks. This newer version is much quieter, on par with slower drives I have. It reminds me of my old Barracuda drive from 2005 that was faster and quieter than my WD Velociraptor drives and managed to outlast them by a year or two as well. It feels solid and works well. I have this in an external USB 3 enclosure, and I copy backup disk images to it every few days. I also keep a copy of my internal data drive's uncompressed files on it. For disk image copies (~2-700GB each) I get sustained write speeds of 220+MB/s (as high as 250 as it goes on). For my data drive copy, which has ... MoreI use two similar drives as part of my backup process.

For my data drive copy, which has hundreds of thousands of small files like photos, documents, and mp3s, it's much slower but gets the job done overnight. I love that this drive has enough write endurance to keep all of my disk images rotating through every day, and long enough shelf life that I can lock it up at a friend's house for offsite backup for 6 months without worrying about it going bad like an SSD might.

Fastest enterprise drives around, as long you do your homework

Fantastic hard drives IF YOU KNOW WHAT YOU ARE DOING. These are enterprise drives that require specific configuration, particularly in their SATA variants. The advertised speeds are achieved by properly partitioning between the two heads and striping. Very easy to do in mdadm or ZFS if you follow scripts readily available online.

Got 4 of these for a Synology NAS, and they are awesome

I'm loving these drives. They are a little bit overkill for a home NAS, but I wanted to build a shared volume that could take better advantage of my 10g network. I have 4 of them in a RAID10, and I'm loving the performance. In terms of noise, my only comparison is an array of 10TB Ironwolfs, and these Exos are louder. The Ironwolfs were never loud enough to be heard over the quiet NAS case fans, but the new Exos can be heard when they seek. I imagine most people buying enterprise drives don't care about noise, but when I was trying to decide on buying these drives (which were cheaper than the equivalent Ironwolfs), I couldn't find noise level data published anywhere. I would say the noise isn't bad, but I definitely have been moving frequently accessed shares back ... MoreI'm loving these drives.

I would say the noise isn't bad, but I definitely have been moving frequently accessed shares back to my old array to keep these new disks from constantly seeking during the day. If I didn't have that choice, I would probably look into moving the NAS farther away from my desk. One of the 4 drives I originally ordered died during the initial scan that was performed while building the array. This actually caused kernel panics in my NAS that rendered the web interface inoperative until I removed the offending drive, so next time I will definitely run extended SMART tests on the individual drives before adding them to an array. The RMA on the dead drive went fine. I don't have a problem with drives arriving DOA every once in a while, as statistically this is just a fact of how hard drives are built and shipped, regardless of the model or brand. And the 4 I ended up keeping are working great!

Lots of storage space. Good price.

This is for a Seagate Exos X16 14TB ST14000NM001G hard drive. I've bought a few in 12TB and 14TB sizes. So far, they have had zero or very few run time hours. The ones that had run time on them had enough hours for testing but about it. They are fast, quiet and seem to work well. Only time will tell exactly how reliable they really are. So far, good drives with lots of storage space. I'm a Linux user and the system these drives goes in runs 24/7. About the only time I cut the system off is during a extended power failure. I also use these in scaled LVM setups. During the initial data moves, these drives see extended constant access. Also, I have no reason to believe these are SMR type drives. They almost certainly are CMR. If it was SMR, it would likely fail during ... MoreThis is for a Seagate Exos X16 14TB ST14000NM001G hard drive. I've bought a few in 12TB and 14TB sizes.

TOO difficult to use for personal

The first surface test after purchase does not proceed. 80 hours left . .100 hours... Infinite. I check the speed but the sequential read/write is 250MB/s, not even half of the catalog. The SATA model looks like only one disk in Windows, so it cannot be striped within a disk like the SAS model. If you don't know how to use it correctly, it will not function as it should.

Working great in my 13 year old Areca 1680

Working great in my 13-year-old Areca 1680ix-24 (ARC-1680), Firmware V1.51 2012-07-04, SAS FW 4.5.3.0 I just bought some Seagate Exos X16 16TB 12Gb/s SAS 512e/4Kn ST16000NM002G HDDs. I have to figure out that the drives wouldn't turn on as my HDD power cable had 3.3V power. I covered the Power Disable pins on the SAS connector and then the drive powered on. After confirming this, I decided to cut the wire supplying 3.3V so my array is not relying on a 3x8mm piece of tape. Anyway, if anyone was wondering if these, or drives like these work on your 13-year-old SAS HBA works with these drives, wonder no more. They seem to be working just fine. I have already done a 20 test and will be doing a battery of tests over the next week. I will be configuring a 4-disk RAID-5 ... MoreWorking great in my 13-year-old Areca 1680ix-24 (ARC-1680), Firmware V1.51 2012-07-04, SAS FW 4.5.3.0 I just bought some Seagate Exos X16 16TB 12Gb/s SAS 512e/4Kn ST16000NM002G HDDs.

I figure that's better than 5-disk RAID-6 as it leaves the one drive free. The purpose is an Emby server (like Plex) on Windows 10. Yes the SAS is overkill but SAS is $235 cheaper than SATA.

Works for a gaming or regular pc, anything SATA

I have had this hard drive for over a year now, no major issues at all, and works like a charm. It’s good for gaming since it’s a 7,200rpm drive, and I have a lot of games downloaded onto it and they play very well. It’s also really nice for backing up files onto it for backup since I have an 8TB external drive for important files to backup as well. I got sick of getting more and more drives when I can just get one big one. It fits just like any other hard drive, and it will work in a gaming pc or a regular work computer that takes a 3.5 slot. Sure it’s not as fast as an ssd, but if you use disk defrag to optimize the drive every so often after downloading or putting files on it, it works fast pulling up files, and plays games smoothly without issues. I highly ... MoreI have had this hard drive for over a year now, no major issues at all, and works like a charm.

I highly recommend this drive if your someone who plays a lot of older games, or even some new ones that aren’t super demanding, store a lot of videos, pictures, and documents. I have a little of everything, and I still have plenty of room left over for more. This would be ideal for someone who has limited room in their pc case, and can only fit 1 3.5 hard drive like the computer mine is in. Worth the $ for all that storage in my opinion. SSDs are nice and super fast, but they are 2-3x as expensive for just half of 16TB.
