Solid drives, high capacity, reliable.

An excellent choice for NAS use; I have two of them in a Synology DS218.

I've been using this external hard drive for over a year now.  It has never failed, never crashed, and has never had any issues connecting.  It holds a solid 2 TB -- nor more, no less.  I access and run my files directly from the drive.  I use it every day, except for some weekends, so I put it through the paces.  And every day, I plug and unplug the cord from the drive, so there are no issues there.  All things considered, it is a well-made, reliable drive.  I highly recommend it.

I have purchased several of these over the past few years for use in a home file server.

These are reliable drives. I am running four of these in a file server, soon to be five, and have been running them for around three years with zero failures or SMART warnings. No drive lasts forever, but so far these just keep trucking along. When the inevitable drive failure occurs, I will likely replace the drives with the same model if it is still available. I highly recommend GSmartControl. It runs in both Linux and Windows, is free/open source, and will provide a full SMART report including the usual indicators of a drive that is going to fail: bad sectors, and number of reserve sectors available. Once a drive has bad sectors and starts remapping reserve sectors, it is time to start migrating data before the inevitable data loss occurs. So far, three years in, I have not a single bad sector across four of these drives.

Speed-wise, they are what you would expect from a 5400 RPM spinning hard drive. Nowhere near the fastest, but fast enough for what I need them to be. Install an SSD for your boot/OS drive, maybe a WD Black 7200 RPM drive for programs, and use these for storing your media files. The important thing to do is gauge what level of performance you need for a particular task and how much money you are willing to spend.

For mass data storage where speed is not a requirement, these drives work very well and I highly recommend them. If you need performance, look at SSDs. If you need speed but also size and do not want to spend a ton of money on a large SSD, look at the WD Black 7200 RPM drives.

I purchased two of these drives and will probably purchase more in the future.  I originally used them in a hypervisor but now have them in a NAS.  These drives are fast and extremely reliable!  I would definitely recommend them!

Pros: They're fast, reliable, and quiet
Cons: None so far

I have 6 of these Toshiba Portable drives, which I've purchased over the last 5-6 years, ranging from 500GB to 2TB. None of them has failed, ever. No glitches, no errors, no issues. They are solid, phenomenal drives. They are feather-light, silent, and tiny.

I write this because I've had three Apple hard drives and two other drives from Best Buy (Insignia and something else) fail in the last few years, while these have performed perfectly. Bravo, Toshiba.

I have purchased a several dozen of these drives for my various projects and for my personal laptop.  They are fast, solid, and dependable drives.  You should treat these as any piece of hardware and regularly check the manufacturer's web site for firmware/driver updates.  An up-to-date firmware can greatly improve performance and functionality.  Out of the 30 or so drives I have of this model, I have had one fail but Crucial replaced that drive in just a few days.  After moving to SSD drives, I have a hard time working on a HDD system now ... so they have spoiled me.

I have several external drives, but this is now my go to drive for backups and external storage.  It may not be the absolute fastest drive out there, but it handles USB 3.0, it's very reliable and has a 5TB capacity for the best bang for the buck factor.  I keep forgetting how much space is actually on this drive so there is no issues with large backups.  It will also turn off when the USB port powers down, if your PC has that feature. Some stay powered on.  Great for LInux and Windows, which is what I use it for.

I  have  several of these drives and they work great.  No need to initialize,  works with my MACS right out of the package.  Lots of capacity.

I tested all 5 USB drives to make sure they functioned properly and they did. Five solid drives with 8GB of capacity for a great price, can beat it!

These hard drives as solid. The intelligent drive firmware really extends out the lifetime of these drives. Not noisy at all. I would know, my NAS is in my living room!

I have used these drives in my home server 24/7 for over 5 years with no failures. Kind of thinking that is beyond belief, so I purchased this extra drive as a hot spare in the raid drive array when it is needed.

Performance and build quality are top notch and has a very reliable and long lasting warranty. My data is of utmost importance. I'm comfortable with this high end Solid State Drive.

Works just fine.  The best part about solid state drives is that they retreive information/data quickly.

I purchased two of these to increase the storage capacity in home PC with a RAID 1 configuration. I have purchased and used Western Digital drives for several computers in the past. They provide very good service and reliability. These drives seem to provide good data transfer speeds. The only drawback I note is that they are noisier than the smaller drives they replaced. With two drives running simultaneously, the clicking is quite audible. This isn't a game changer, though, as the drives meet my needs well.

I've used a lot of WD drives.  I have 3 of these 6TB drives in a Windows parity array.  Seem to be doing well so far.

After having bad experiences using both consumer drives (bad I know) and low power drives in budget NAS solutions, I decided to go with enterprise level products for a new NAS.  I have yet to have any SMART errors or erratic behavior.  They are in a QNAP TS-269L that handles media and file serving (three macs, two PCs) and Time Machine backups (for three macs).  They are a bid louder than your typical hard drive all around and are clearly audible during access, but for a device with that many power-on hours the piece of mind is well worth it.
These are in a RAID-1 configuration and even during I/O intensive tasks such as time machine backups, throughput is excellent.  If I were to do it all over again with the same number of bays or more, I would get more of these but in a higher capacity.  All the enterprise drives I've had from Seagate have been excellent whether a 15k. 2, 15k. 5 or even the Constellations.

These are very reliable drives. I have had no issues and the price is great.
