Good Quality and it Works Fine with a MacBook Pro
Capacity: 5TB
As a music producer, my last external drive was much smaller and it began to fill up quickly. I bought this Seagate because of the known quality, and the size. I understand that with a Windows computer, it’s plug and play. If you use a MacBook Pro, it is a simple task to prepare it. I’ll copy instructions for Mac preparation. It was ready to go in about a minute. It’s not something to worry about. Here are the instructions: First an easy installation, you’ll use Disk Utility on the Mac to erase and reformat the drive; it’s straightforward and only needs to be done once before you start using it. 1. Decide on a format For a drive used only with your MacBook Pro for plugins/projects: APFS (best for SSDs, modern macOS, fast and robust). If you also want to plug the same drive into Windows regularly: ExFAT (works read/write on both Mac and Windows, fine for large audio files). 2. Erase and format the drive Connect the new external drive to your Mac. Open Disk Utility (Applications → Utilities → Disk Utility). In the menu bar, choose View → Show All Devices so you see the whole physical disk, not just volumes. In the left sidebar, select the top-level entry for that external drive (it will usually show the manufacturer’s name and “Media”). Click the Erase button at the top. In the dialog: Name: Something like “Audio Plugins” or “Samples”. Format: Choose APFS (or ExFAT if you need Mac/Windows). Scheme: Choose GUID Partition Map if offered. Click Erase and wait for it to complete, then click Done. After this, the drive will mount on the desktop in the new format and you can start moving plugin content or sample libraries to it. It took time to move data off the old drive and load onto the new drive. That’s natural. With this new Seagate drive, I store all my music plug-ins and virtual instrument files along with a large collection of audio and midi files. When producing music, there’s no delay and everything works fine. With that said, I have the new M4 chip and 48GB of Ram. With that, the computer works fine, but the Seagate also keeps up just fine. This Seagate external drive was a good purchase. It is reliable, portable and built well with a good appearance.

Hard drive 4TB
Capacity: 4TB
The Seagate Portable 4TB External Hard Drive is a great option if you need a lot of extra storage without spending a fortune. It’s compact, easy to set up, and connects through USB 3.0, making it convenient for backing up photos, videos, documents, and other large files. Real-world testing of similar Seagate 4TB portable HDDs has shown roughly 100+ MB/s read/write performance, which is plenty for everyday backups and file transfers. What I like most is how simple it is to use—plug it in, and you can start transferring files. The 4TB capacity gives you plenty of room to consolidate files without constantly worrying about running out of space. The biggest downside is that it’s an HDD rather than an SSD, so it won’t be as fast or as resistant to drops as a portable SSD. I’d also recommend keeping important files backed up in more than one location rather than relying on a single external drive. Overall: 5/5 ⭐ — excellent storage capacity, easy to use, portable, and a practical choice for everyday backups and extra storage.

This is a slow Hard Drive, not a fast SSD
Capacity: 2TB
To be clear, it is a hard drive not a SSD. It seems to save about 10 MB per second whereas a SSD could be 100 times faster at 1 GB per second. So overall it is a 10-year older technology that is less reliable or robust and slower than a Solid State Drive. Maybe I was mistaken when buying this but it wasn't clear to me this was not an SSD and that it would write this slowly.

The first one ordered was defective - quick replacement sent
Capacity: 2TB
The online tech support by Seagate leaves a LOT to be desired as the problem was, I could see the device in the printers, scanners and other devices on my computer, but it would not show up in File Manager where I should have been able to "drag and drop" stuff into/onto that drive. I did EVERYTHING I could think of - I tried it on my desktop, then my laptop, turned the computers on and off, unplugged the drive and nothing worked. I went to Seagate's online support and one of their videos stated, "try another cable - sometimes cables go bad." Uh, DUH, this portable drive has a very unique and proprietary type of cable! It's not like one end is a regular USB plug and the other side is a USB-C plug! It's sort of like a double USB-B or micro-USB plug, but two of them put together and one side is smaller than the other side, so, "try a different cable?" Puh-leaze! However, I requested a return of that original and asked for another of the same hard drive be sent. Got it today and IT WORKS PERFECTLY!!! Yes! I plugged it in and BOOM! There it was in File Manager. Checked the properties and it has the space I expected it to have. Then I did a drag and drop of an MP3 file just to see if there would be any problems and the file copied over to the new hard drive without issue. THIS is what I wanted and am happy to have - a great little external hard drive that works just as it should at an excellent price.

Cheap bulk storage that still works years later — yes, it’s a spinning drive
Capacity: 2TB
I bought this Seagate Portable 2TB USB external hard drive in January 2023, and I’m still using it years later. It’s relatively inexpensive for the capacity, and I’ve always found Seagate reliable. I’m happy with it. I knew going in that I was buying a mechanical hard drive, not an SSD. The listing is the everyday plug-and-play USB 3.0 portable HDD for Windows/Mac backup and file storage. It can be a little slow sometimes — it is what it is with a spinning disk. That tradeoff was expected, so I don’t ding it for being an HDD. Five stars for the storage, the price, and long-term reliability that matched what I paid for.
