Review: Unparalleled Performance and Reliability for NAS Enthusiasts! - The Seagate IronWolf Pro 10TB NAS Internal Hard Drive is an absolute game-changer for anyone serious about their Network Attached Storage (NAS) setup. After several months of rigorous use, I can confidently say this drive has exceeded my expectations in every way. First and foremost, the 10TB storage capacity provides ample space for my extensive multimedia collection, critical backups, and countless files. This capacity is a sweet spot for users who need a balance between space and cost-effectiveness. The performance is top-notch, with the 7200 RPM spinning speed ensuring swift data access and transfer speeds. One of the standout features for me is the CMR (Conventional Magnetic Recording) technology. This ensures consistent, reliable performance even under heavy workloads, making it ideal for demanding environments. I've experienced no drop in speed or reliability, even during simultaneous, high-bandwidth access from multiple devices. The 256MB cache is a crucial component, significantly boosting read and write speeds for frequently accessed files. This cache has made a noticeable difference in the fluidity and responsiveness of my NAS, particularly during peak usage times. What truly sets the IronWolf Pro apart is its compatibility with RAID setups. Whether you're running RAID 0 for maximum speed or RAID 1 for redundancy, these drives handle the load with grace. The reliability and consistency under RAID configurations are nothing short of impressive. Seagate's Rescue Services is the cherry on top of an already stellar package. Knowing that my data is backed by Seagate's data recovery service provides peace of mind that's truly priceless. I haven't had to use it yet, but it's reassuring to know it's there. Installation was a breeze, thanks to the SATA 6Gb/s interface, and the drive runs cool and quiet, even during extended usage periods. It's clear that Seagate has put serious thought into both the performance and longevity of this drive. In terms of value, while it's an investment, the IronWolf Pro's durability, reliability, and performance justify the price tag. I consider it a long-term investment in my data security and storage needs. In summary, the Seagate IronWolf Pro 10TB NAS Internal Hard Drive is a testament to Seagate's commitment to quality and performance. It's a rock-solid choice for anyone serious about their NAS system. The combination of high capacity, CMR technology, RAID compatibility, and Rescue Services make this drive a standout performer in its class. Highly recommended!

## Questions & Answers

**Q: I purchased  (2) 12-tb: anyone knows why i get 10.91-tb for each?  why are we short?**
A: Hard drive manufacturers use base 10 for size.  So 1 TB = 10**12 bytes.   Your system uses base 2 for counting, so 1 TiB = 2**40 bytes.   A base 2 TiB is larger than a base 10 TB.   The actual name for a base 2 terabyte is a tebibyte, or TiB.  A base 10 TB is TB or terabyte.

**Q: Can this be used as a normal hdd storage drive for a desktop pc?**
A: Quick answer YES 
The more complete answer starts with 'WHY'? 

First, NAS rated disks are typically more expensive than desktop drives.  They are built for different use expectations.  
One of the answers mentioned always leaving the system powered on.  Most NAS setups are powered on and left on.  They do not power cycle (and more importantly heat cycle) with any regularity.  As such, the drives are built to operate in that environment.
Another answer mentioned RPMs and many NAS drives spin at 5400/5900 RPMs.  This means that the place on the platter where you file is stored takes longer to rotate around than it would on a typical desktop drive of 7200 RPM.
Another answer mentioned vibration.  The desktop is less vibration isolated (typically) than a NAS setup.

Shop a 7200 (or faster) RPM disk or consider NVMe or SSD is the budget allows.  You will not only likely save money initially but will have better performance in the longer term.

**Q: Is this drive smr if so i don't want it!**
A: At least the IronWolf Pro drives are all CMR (=PMR), and not SMR. I think some of the smaller capacity non-Pro drives used to be SMR, but I think now even they are all CMR.

**Q: Does this drive come with sata cable?**
A: No it's a bare drive no screws no cables.

### ⭐⭐⭐⭐⭐ Great price, warranty and usable speed.
*by P***D on August 23, 2022*

I have placed on of these drives in a NAS as a single source for storage to run it through its paces. This is designed for NAS and while I cannot say how it performs in a RAID scenario, it was able to do as hopefully expected with reads and writes and play nice with the NAS OS. Having to compare to a 5 bay older NAS with 4 tb drives, the single drive in the NAS does appear to be a bit noisy. The three facets are - NAS case design, the drive itself and not being engage in a RAID. I know that larger drives can be a bit noisy and I'll make adjustments externally to neutralize some of the noise and more so, when populated with other same drives for RAID. I got this drive at a good price from* Amazon itself and will soon check with Seagate on their warranty. Last- yes, assuming no issues in the near future, I would buy again... 2-3 more of these.
