Llegó antes de la fecha. Es más pesado y ancho que el modelo anterior probablemente por la capacidad en terabytes. Espero que la durabilidad vaya acorde.

I recently picked up a 22TB external hard drive, and so far it’s been a great value for amount of storage you get. The capacity is huge for the price, which makes it appealing option if you need a lot of space without spending a fortune. Physically, it’s a typical external drive—nothing oversized or bulky—so it fits easily on a desk or shelf. One thing to note, though: it can get a bit loud at times. I wouldn’t recommend keeping it running full‑time in a quiet space like a bedroom office unless you don’t mind some background noise. My main use is offsite backups, so I only plug it in for short periods. Because of that, it’s too early to say much about long‑term reliability. Performance‑wise, it’s not the fastest drive out there, but it’s perfectly adequate for backup tasks and general storage. Overall, if you need a ton of space at a reasonable price and don’t mind occasional noise, it’s a strong choice.

I have several smaller hard drives I use to store photos and old files but they are getting old and it is hard to organize files, especially photos across several drives so I was in the market for a large hard drive to better organize my old files. I opted for the Seagate 22TB drive because of its' size and, for the size of the drive, it was relatively inexpensive compared to other options. Things I like about the drive: 1) It has a large capacity but is relatively small compared to my other external drives; 2) it is plug and play. I have some drives my system has a hard time identifying sometimes but there are no issues with this drive; 3) everything works out of the box. I have had no issues so far; 4) I use it on 3 systems and it works well on all 3 systems and is easy to move from one to the other. It is not my fastest drive. have a portable Sandisk SSD that is faster but it has not been a problem. You can hear it working but it is not annoying. Overall I am very pleased with the Seagate Drive.

I purchased the 22TB in Dec of 2025. So far, so good. Good value. I can't speak to all of the variations of the product, but this one came with a power supply, which includes lots of adapters for what I imagine works in most countries. It also came with a 3 foot usb cable for connecting to a usb-A port. It arrived pre-formatted exFAT. So, out of the box, it am able to use it with both my Windows PC and my Mac. Making it very convenient to move files back and forth to both. It has 20TB available disk space empty. They do note though that if you intend on using it with Mac's Time Machine for automated backups. you'll need to reformat it for Mac (only). It runs relatively quiet. However, I have it sitting on a wood table and I do hear thumping during read/write as the table acts as a sounding board... This could be reduced if I were to put it on some sort of surface that absorbs the vibrations. It runs warm, not hot during very active sessions of moving files to it. Over all, very pleased.

I paid $249 for 22TB's of storage, and all I had to do was shuck the hard drive and put it in to a DAS. Inside was a Barracuda drive, which I have used successfully in the past and still have a couple from many years ago. I noticed the price climbed a couple days later to $289 (still worth it), so I did pretty well. To give context on the pricing, I just purchased a bare 20TB HDD before this one for over $400. If you're planning on doing the same as I, buy a cheap bezel knife to make the process easier, and the best DAS enclosure I found was a Terramaster D4-320 (at the top of the picture). Stay away from WD hard drives and go with Seagate if you want to do this, WD has anti-shucking measures that can create issues and those drives don't last (ask me how I know). Seagate, thank you for remaining consumer friendly, I am happy to remain a dedicated customer.
