Received original Seagate hard disk.

Don’t. Buy this. Product. It has 3 yers warty. But after finish warranty. Its. Stop. Working. Don’t buy this product

I bought a 4TB Seagate Ironwolf drive to replace a WD drive I had that was giving errors in my UNRAID server. I have not bought a Seagate drive in a very long time. There was a period of time when Seagate was great, then a period of time when they were not so great. Anyway, I figured I would give Seagate a try again, especially since their drive was $15 cheaper than the same WD drive at the time. I received my drive and it was well packaged in protective packaging and inside a box. The drive had the same familiar footprint dimensions but was a shorter height which was interesting. Anyway, it didn't make a difference really. I removed my failing WD drive from the server, and then slotted this seagate drive in. I then started the server and once booted I assigned the drive to the correct slot in the menu and the server immediately began rebuilding the data on the new seagate drive. The drive had zero issues and zero errors on it from testing and rebuilding. It delivers good read/write speeds, but read/write speeds are really dependent upon many factors and what the server is doing at the time and so forth, so no detailed reports on that. The Seagate drive has been running 24/7 on my server for about a month now and not a single issue with it so far. The shorter height is interesting as it lets more air from the front facing fans pass between it and the drive above it, so that is a plus I suppose. If this drive holds up for 6+ months I will probably replace more of my server drives with Seagate drives. I have 2 other server drives coming on replacement time in near while, so I will be purchasing at least a couple more of these as they go on sale from time to time. I will need to compare the longevity of the Seagate drives with the WD drives. I've had good luck with WD up until about a year ago. Now, their drives do not seem to be of the quality that they once were. I get a lot of errors on some WD drives sooner than expected. Hopefully these Seagate drives fair better. Anyhow, so far so good. -------------------------------------------- UPDATE 15AUG2025 -------------------------------------------- So, a 4TB WD RED PLUS drive in my server went bad. The drive is 4 month old. It started about a week ago with some Sector Reallocation errors, then more errors over the days... then hundreds of bad sectors. I couldn't write data to the drive anymore, then the server kicked out the drive and refuses to start it up. I pulled the drive and tested on my PC... yeah, the drive is going bad, and it is going bad fast. I formatted it, put it back in the server (to trick the server into thinking it was a new drive), it rebuilt the data (after about 10 hours or so), and all seemed fine. But, soon after (within hours), it started acting up again. Definitely a bad drive. I can read data from it, but writing to it is challenging as it triggers a cascade of sector errors. Had to call WD today and RMA the drive... now I have to pack it up and ship it at my expense to get a replacement. Honestly, it's probably not worth it. I do not want another new WD drive in my server. I'll probably put in on light duty on one of the kids PCs or something instead. WD's quality has fallen into the toilet, and this new drive I will get from them will probably be another bomb waiting to happen. You know sticking in a new replacement into the server and waiting 10 to 12 hours for the data to rebuild is not particularly fun. WD I am not impressed in the slightest. This is particularly bad since this was a BRAND NEW RED PLUS drive. I not long ago replaced another WD drive with a Seagate. A brand new WD Red Plus..... and sitting next to it is a 5 year old WD Blue purring away happily without complaint... WOW! What happened to WD?!?!?! I have a 7 year old WD Green (they don't even make them anymore) that still works fine... and a new RED Plus can't make it past 4 months. Amazing. I even have a WD Blue that is years and years old in my security camera DRV/NVR recording 24/7... never has an issue...WD used to make good product. They are garbage now in my opinion. So, guess what I ordered as a replacement for the RED PLUS? Yep, I ordered a Seagate Ironwolf... even though WD is giving me a replacement (which you have to wait weeks and weeks for), I am paying for another Seagate to replace it with. The Red Plus will never see the inside of my server as I do not need the aggravation. It might be a long long long time before I ever order another WD drive again. Not until they sort out their quality again. My advice is to stay away from WD drives.... it is hit and miss with them. It is like playing Russian roulette with your data. So, we are down to two players left in the HDD world; Seagate and Toshiba. But, for now I am happy with Seagate. -------------------------------------------- UPDATE 06OCT2025 -------------------------------------------- I did finally receive the replacement WD RED Drive. WD sent me a white label drive instead of a RED label drive. It's basically the same drive but it has a label that looks like some printed on a thermal printer type label that they must issue when doing replacements or something. I didn't put it in my server. Instead, I have replaced 4 drives in my server with Seagate drives now. I even replaced my parity drive with a Seagate at this point, since it was a WD and started giving SMART warnings as well. So, the UNRAID server is almost entirely Seagate drives now and everything is running happy and smooth. The LSA HBA card has no issues with these drives at all and UNRAID sees them as normal SATA drives (normal as if they were connected to the motherboard directly)... just in case there are any UNRAIDers out there considering a LSA HBA card... I used a 9300 16i that was already in IT mode... zero issue with it with UNRAID... plug and play literally, the drivers come up automatically during boot. Anyway, the Seagate drives have been awesome so far. -------------------------------------------- UPDATE 01AUG2026 -------------------------------------------- The Seagate drives are still purring away happily. No issues at all. No errors, no SMART warnings, no data issues. Exactly how you want your drives to work. My only complaint these days is price, but, to be fair that is every manufacturer now so I am not singling Seagate out for this. I would buy more drives but I can't justify it at these price levels. Even if I had a failure and needed a replacement I would seriously consider migrating parity data (backing up from parity) to the existing remaining array and just live with one less drive on the server for now. If my parity drive failed, I would move data off a drive to other drives and move that drive to parity and rebuild the parity. This is a super time consuming process but at these prices I have the time. The 4TB Ironwolf should be around $89 to $100 max. At $200 (including tax) this is twice the price for the same storage. This is a 100% increase in price in just over half a year or so. The higher capacity drives are just not even in reach for most hobbyists or people. And if you run a server you need to upgrade at least two drives when you want to go up to a larger size (UNRAID requires a parity drive the same or larger than your largest drive in your storage array (or pools), other servers depending an RAID structure might require you upgrade all drives (in a pool) to the same size including any parity or backup). 4TB is not a lot of storage by today's standards and I know I can fill it up pretty fast. I mean at these levels I might have to break out my spindle of rewritable Blu-ray discs for backup. Yes, I still have optical drives. I've already started using DVD-RW's again for small things. The costs of HDD/SDD/DRAM/GPU is insane. It is starting to make more sense, again, to buy cheap DVD and Blu-Ray movies to keep them on optical to avoid using HDD storage. Garage sales are my best friend these days, especially if I can find a not too old PC for cheap and cannibalize drives (and maybe other parts) for less than buying them online. I have 3 computers, 1 server, and a security system in my home network. ZERO hdd/sdd/dram/gpu or flash drive upgrades going on these days. Hopefully things change in the future. Fingers crossed. But the Seagate drives I did install, when they were affordable, are working great. So, if you really really really need a drive and can't wait and are willing to spend crazy money, consider carefully. At these prices drive selection is a critical decision now. Throwing away $200+ dollars is no small thing, and at high capacities you are getting up there in the $350, $500+ range. Choose wisely.

Seegate HD lerde çok eski ve sağlam bir marka. Bir çok modeli var. Ben bilgilerimi yedekleme amacı için kullanıyorum. 4 TB olanı tercih ettim. Depolama amaçlı olduğu için 5400 devirli olması daha sağlıklı. Birde CMR tipi yazma özelliği önemli. CMR HD ler NAS veya Raid olarak da kullanılabilir. Tabii 1 tane yetmez. Ben 4 TB ve 6 TB olanları tercih ediyorum. En az çift yedek alıyorum. Çalışan sistemlerde zaten M2 veya SSD kullanılıyor. Bu HD yi her türlü amaç için kullanabilirsiniz. Güvenilir ve sağlamdır. Yalnız piyasada bir çok yerde Bu tür HD leri yenilenmiş olanlarını da yeni fiyatına satıyorlar. Onun için Amazon haricinde hiç bir yerden almıyorum.

Produto muito bom

Fast international delivery and a great price for an authentic newer generation Ironwolf 4TB disk. It's currently running very well in my NAS and the RAID array is rebuilding without issues. Thank you!

Review: I’ve been running two of these Seagate IronWolf 4TB drives in my UGREEN DXP2800 (2-Bay) since April 2025, and the experience has been flawless. If you’re building a home server and worried about noise or heat in a small space, these are exactly what you need. The "Sofa-Side" Silence Test: Living in a downtown Toronto condo means my tech setup is often in the living room. I have my NAS sitting right next to my sofa, and I was worried about the "clicking" sounds typical of mechanical drives. To my surprise, these are virtually silent. I can watch movies or read a book right next to the NAS without even noticing they are spinning. Performance & Reliability (CMR Technology): Don't let the 5900 RPM fool you into thinking they are slow. Because these use CMR (Conventional Magnetic Recording) technology, they handle RAID rebuilds and heavy data writes much better and more reliably than cheaper SMR drives. In my UGREEN setup, the speeds have been consistent, and I’ve had zero lag when streaming 4K movies or backing up my laptop. Thermal Management: I monitor the temperatures regularly through my NAS app, and these drives always "stay in the green." Even inside a compact 2-bay enclosure, they run impressively cool, which gives me peace of mind for their long-term lifespan. Pros: * Quiet Operation: Perfect for studio apartments or living room setups. * AgileArray Firmware: Specifically optimized for NAS, keeping the RAID stable. * Reliability: Designed for 24/7 operation (though I have a custom sleep schedule to extend their life). * Rescue Data Recovery: Includes 3 years of data recovery services from Seagate, which is a huge safety net. Cons: * Physical Size: As with all 3.5-inch HDDs, they are bulky, but that’s the standard for this much reliable storage. Pro Tip for NAS Users: Even though these are rated for 24/7 use, I’ve programmed my NAS to put the drives to sleep during inactivity and shut down the system at night. This not only saves a bit of electricity but also reduces the wear and tear on the mechanical parts over time. Final Verdict: If you’re building a home NAS and care about silence, reliability, and long-term stability, the IronWolf 4TB is a no-brainer. It quietly does its job 24/7 without heat or noise issues, even in small living spaces. A true set-and-forget drive for any home cloud setup.
