## Description

Review: Nearly 2 years of always on. Still working reliably, but noisy. - I've been reliably using this product for 2 years in a JBOD box with only this HDD in it. I paid 14.1GBP/TB for it at the time of buying in Jan 2024. I get reliable speeds of upto 100MB/s for big files I was told to keep this drive on as much as possible so I've always left the power on for the JBOD box. I have attached the rest of the data from CrystalDiskInfo in the image. The only downside is that the drive is really noisy. If you've never heard a mechanical data center drive spin, you won't know what you're walking into when you buy an Enterprise HDD. Ofcourse the drive wasn't original and typing the warranty number from the drive on seagate site said it wasn't meant to be sold separately, but 2 years of use has done it justice. Besides, I use backblaze so my data is cloud backed up anyway
Review: High quality storage at an exceptional price but check your hardware for compatibility - Easy to install ? Yes. It's a standard size 3.5in SATA HDD Storage capacity - phenominal for the price. Speed is more than acceptable and it is constant, not like many SSD's So I give it a wholehearted 5 star review. Time will tell on its longevity but it supposed to be enterprise grade so I've no concerns there. It runs at 39'C all day and every day. Now the tricky bit. Make sure the drive can be installed into your system. I'd planned to put it in an external 5-bay hub but realised that the hub can only take up to 16GB drives per slot. Luckily, I could fit it into my PC which recognised the full capacity while giving SATA speeds. The additional cost for an extra 2TB over a 16TB drive was a no-brainer.

## Features

- SCALE: Run Big Data applications for very large scale requirements
- EFFICIENCY: Consistent performance with low latency and repeatable response times through improved caching
- HIGH CAPACITY: Supports data analysis and other dense architectures for maximum rack efficiency
- COST EFFICIENT: Optimises total cost of ownership by reducing cost per terabyte
- RELIABILITY: 2.5 million hour MTBF and 5-year limited warranty ensure maximum reliability

## Questions & Answers

**Q: Mismatch product listing! title and listing description say ironwolf pro drive. picture descriptions advertise exos x18, which is it im purchasing?!**
A: When I brought directly from Amazon it was the Exos. But you’re right, the current 18tb drive from Solv4X shows as Pro drive (including the model number in the description). I would suggest to contact them for clarification.

**Q: Is this for ironpro or exos? title is conflicting**
A: This is 100% confirmed to be an EXOS drive, you won't get an Ironwolf Pro at this price.

**Q: is this exos or pro drive? @Seller**
A: This is confirmed to be an EXOS drive by many buyers. You won't get an Ironwolf Pro at this price.

**Q: For the drives sold by sand, do these ones get the 5 year warranty from seagate, or were these part of a larger system being sold off individually?**
A: No, Sand seem to be selling parts of a larger system. I've returned mine unopened a few days ago because of that. I can't answer for other sellers but if anybody knows which ones do offer 5 years warranty I would be keen to know.

### ⭐ Beware! No Seagate warranty on this drive, which was not meant to be sold separately
*by C***N on 29 August 2022*

I purchased this drive from the seller MELVYN-EU. When attempting to register this drive on the Seagate website, I was told that there was a problem with the warranty. When I spoke with a customer rep, I was told "If you hover your mouse on the red writing you will get the message that product was originally sold as a part of a larger system. Please contact the system manufacturer or your place of purchase for warranty support. In other terms, this drive was not meant to be sold as a separate stand alone internal enterprise disk but was removed from a larger system, (a server most likely) that was made by Dell, HP, IBM, etc, it was dismantled and then sold in pieces." Seagate drive are good, but do fail, and I have had to use warranty support on several drives in the past. Purchasing a drive, without full Seagate warranty support is an absolute no, no for me, and so this drive is going back. Attached are pictures of the chat with the Seagate rep.
