Exos X20 20TB 512E/4KN SATA, 7200RPM, 3.5", 256MB -ST20000NM007D

Will it make noise, of course, it's a HDD, not an SDD. But is it also a solid piece of equipment, yes. I have this running a lot and haven't noticed any real degradation in performance at all.

20TB is more expensive per TB than lower capacity drives but is a great upgrade and power savings from multiple smaller HDDs I was using.No issues and works perfectly in a USB enclosure.

Even though I only backup 1x/ay and the backup is a small,4gb. Very quick to populate directories. seek time are also, far within parameters......

Damian's review of Exos X20 20tb Sata 3.5in 7200rpm 6gb/s 512e/4kn

Pros: The price is amazing, especially considering the capacity. The reviews said that it was noisy but, if anything, it's quieter than my other HDDs.Cons: Nothing will change my opinion of this drive. Apart from when the 22TB version is released...

Exos is Best Sauce!

I'm on my 8th drive and *knock on wood* no issues or failures. I've purchased from X16, X18, and now X20 series. They've been flawless. I'm using mine in NAS setups and they see a consistent workload pretty much 24-7. These are designed for data centers so no concerns. They are noisy for hard drives. If noise is a concern the Iron Wolf series is quieter. But Seagate claims twice the mean time between failures for Exos so it's worth it in my opinion. The internet seems to hold the Exos line in high esteem so I felt the was the best option for me.Read write performance varies based on workload but in my setup doing file transfers I've seen single disk speeds of 265MB/s read and 170MB/s write. That's about the limit of my setup so I can't speak to what your results ... MoreI'm on my 8th drive and *knock on wood* no issues or failures. I've purchased from X16, X18, and now X20 series.

That's about the limit of my setup so I can't speak to what your results will be. The onboard cache seems to be plenty. I know other disks are moving to larger caches but I'm not sure if it's needed for a single actuator drive.I've got 150hrs+ on this drive so we're probably out of the risk zone of dead in a day or two problems with HDDs. I have thousands of hours on the X18s and X16s. And much of that is write cycles. I highly recommend Exos for any kind of storage use case. For instance this unit I placed in a 3.5in external enclosure for portable storage. And it still came in less than what some 20TB external drives sell for. Plug for the NOVUS usb enclosure. It's a great box for these or any other 3.5in HDD.

Great high capacity SATA drive for NAS

Works well in Synology DS1817+ even though it is not on their current compatibility list.

Loud, one DOA

I have normally ordered WD and HGST drives, so my initial thought when I heard these Exos X20 drives was that they had internal mechanical issues. After researching, this appears to be "normal" for the Exos line which is disappointing. I'll look elsewhere next time. Due to cost savings and availability, I bought these instead of WD Gold 20TB or its twin HGST version. Wish I hadn't.

Works like a charm in QNAP TS-653D

I added this to my HDDs in my QNAP TS-653D. It works without a glitch.I've bought a number of Seagates over the years, and I've had no issues.
