    Huge space! FAST.
    1ST. Please note I have blacked out the QR codes & serials on the pics. ...Just so you know. The drives don't look like that with big black marks on them!These drives (24TB IronWolf Pro) are just working great. I have a pair of the 14TB IronWolf Pro's that I got 3 years ago & they have been really good too, but they seem a little slow now compared to these.These are working perfectly & seem faster than pretty much any traditional (mechanical) hard drives I've ever had.The drives are 7200 RPM & are in the 3.5 inch form factor.These do have to be initialized & formatted in Windows Disk Management before they can be used. After that, they were recognized by Windows immediately.You will want to choose GUID (GPT) as the partition type for large drives like this, & then format as NTFS for Windows machines. Then they will show up with a drive letter & you're in business.My two drives arrived in perfect condition, and when checked out had no errors or bad sectors etc at all. Both had ZERO hours on them and they are brand new drives.You do lose a big chunk of space when formatting in Windows, so expect the formatted drive for the 24TB models anyway, to come out to about 21.8TB usable. ...It's just a Windows thing unfortunately.Transfers on these huge drives as I said are VERY FAST, and I just could not be happier with my drives thus far.I've had great experiences with the IronWolf Pro drives from Seagate in the past few years.So these are highly recommended.

    I rarely write a review but decided to. First, I am old, like dirt. Retired as a system, network, cyber engineer a long, long time ago. How old? I started with Assembly language and the OSI model. LOL.
    I still enjoy playing with computer stuff though.

    I don't use these drives in a NAS but do use the IronWolf drives for my media server (recently rebuilt on a mini pc) from the old tower which I keep as a backup. I really like these drives. They can run 24x7 or on/off, depending on the system. I use them as my backup media across my desktops, laptops and servers via 6e wifi and also direct attached. They hang off external USB to SCSI enclosures and run like a charm.

    Well, so much for the background. The first three I bought in 2021. The next in 2022, another in 2023 as a replacement and now an IronWolf Pro just ordered as another replacement (7200RPM!) a few minutes ago.

    Real world experience is simply this. As of today, the last one bought in 2021 is showing signs of file corruption. Nothing major, but definitely getting some bad blocks. I scanned the drive and repaired it, but in my world, it is either perfect or replaced. Sure, they could probably go for another year, but I don't want the hassle. And for a few extra details. The drives did all not get the same usage. Some have one year, other three years. The one-year usage ones are running great, the three-year ones are showing errors.

    My conclusion? The IronWolf drives are great for the money. Whether in an on/off environment or 24x7, they give a solid three years of great performance and reliability.

    I decided to buy the IronWolf Pro 4TB running at 7200RPM for a little extra spin for those Ultra 4K movies. It was only 20 dollars more.

    They get my vote, just plan a three-year endurance unless you are running a NAS. Then it is not that big a deal. Enjoy!

    PS: I was going to buy SSD's, but with the crazy price increases since the first of the year, I'll stick with HDD's. They work great for my purposes.

    I've used Seagate IronWolf drives for NAS storage for years and have always had good results. This is no exception. The 20TB capacity is great and I was able to purchase this one at a very fair price. These platter drives are considerably less expensive than solid-state drives with comparable capacity, but also a fair bit slower and noisier. The noise isn't really objectionable, but you can definitely hear them ticking and grunting from several feet away. The sound is about as loud as moderate rain falling on the roof. SSDs would be very nice but would cost a whole lot more. For simple file storage and retrieval, these are more than sufficient. If I were running programs from the drive (like data-intensive games or video editing) these drives might not be ideal but for storing video files or other data, they work great.

    Style: HDDCapacity: 8TBVerified Purchase
    After outgrowing the storage capacity of my previous NAS setup, I decided to upgrade to the Asustor AS5304T and populate it with some high-capacity Seagate drives. I had heard great things about Seagate's IronWolf line of drives being purpose-built for NAS environments, so I decided to go with the 8TB models to populate my 4-bay unit.

    Right out of the box, the solid build quality of the IronWolf drives was apparent. Installation into the Asustor was a breeze. After configuring them in a RAID 5 array, I started transferring my data over from the old drives.

    I've been thoroughly impressed with the transfer speeds - I'm getting those real-world write speeds over 180 MB/s. The 7200 RPM spindle speed and 256MB cache give the 8TB IronWolf a nice performance boost compared to lower capacity models.

    But what's most important for a NAS drive is reliability, and the IronWolf seems built to handle constant 24/7 operations without issue. Seagate's rotational vibration sensors and error recovery control features give me a lot more confidence, and given that I'm not yet hardcore enough to keep even more backup servers going, I like feeling secure with each of the drives in my current RAID 5 setup.

    Do NOT ignore Seagate's AgileArray technology which optimizes the IronWolf specifically for RAID environments like my 4-drive array. It's clear this drive was designed from the ground up with NAS usage in mind. Even under heavy read/write loads, the 8TB IronWolf drives have stayed cool and performed flawlessly in my Asustor. It has also meant that on the two occasions that I had an inproper server shutdown (totally user error on my part), reconfiguring without data loss was relatively quick (<3 hours compared to my old setups 19 hour record).

    Overall, I'm extremely satisfied with my purchase of the 8TB IronWolf drives. The combination of high capacity, enterprise-grade reliability, and great performance makes them an ideal choice for my demanding home NAS needs. If you're looking to upgrade your NAS without compromises, the IronWolf line deserves serious consideration.

    I've bought at least a dozen of these drives and have not had a problem over 5 years. Are specifically for NAS storage, meaning long term, reliable, cost effective, data storage. Speed of the drives are as expected for a platter disk.

    Reviewed in Canada on January 18, 2023
    Style: HDD ProCapacity: 4TBVerified Purchase
    I ordered two of these drives yesterday and they arrived today. I bought these for storing image backups for two super micro computer systems. I I keep redundant backups.

    I installed each of these drives in to a USB-3 external drive enclosure. Made a full partition and formatted them NTFS with the default sectors. With the first one I made a full system image backup of the main boot drive containing the OS, the locally installed programs, and the local user files. I was surprised at the speed this backup finished. This drive performs very decently. There was a lot of data to back up.

    The two drives will be connected to the servers and be accessible 24/7 doing automatic scheduled image backups along with restore points. For my computers I keep 4 separate full backup images (two image backups are kept off line). This type of redundancy allows for very good and reliable security. I cannot afford to have a system down for a long time because of failed backups in case of a crash or some other fault where data and or system recovery can easily fix the issues.

    If I had to restore one of the super micros from the backup image, it should come back within about 60 to 80 minutes. While the restore is happening I can go have my dinner. When I get back the system should be back up and running as if nothing happened. If I had to install one one of these computers with everything from zero as like when new, this could take me over three days of full time work. Very frustrating and time consuming work.

    --

    This is the first day using these drives and so-far they have been working well. At present I cannot comment any experience with long term use. In the past I have been using Seagate drives for data storage and backup system images, and had very good experience with them.

    I had to replace a 2TB Seagate backup drive yesterday because after 11 years running 24/7 it failed. This drive served me very well. It was used for backups over three generations of servers. During its time it was considered a huge drive.

    Tip: To make drives last longer have a fan blowing air on them. Drawing the heat from them makes for greater long term reliability.
