Seagate BarraCuda 4TB Internal Hard Drive HDD – 3.5 Inch Sata 6 Gb/s 5400 RPM 256MB Cache for Computer Desktop PC Laptop (ST4000DM004)

The large cache size makes these drives good performers despite the slow platter rotation speed. I've used four of these in a zfs raid NAS backup device for the last two years WITHOUT ANY ISSUES. I have two other ones in Desktops for storage that haven't had any problems either. Whether these come DOA depends as much on your delivery person/service as it does on Seagate manufacturing. The way they come packed, a hit to the side or bottom of a box will be absorbed without any problems. Any hits to corners in diagonal vectors will transmit the hit to the drive. There's not much that can be done about this except packing them in inches of loose popcorn. And delivery services aren't consistent either. With Amazon's generous return policy, don't worry.Back in the mid 2000's I did send a smaller drive back to Seagate for warranty service, which was slow and painful--but what warranty claim isn't? I did get a refurbished drive in return, which continued to work until I replaced it with a larger drive years later.These are great drives for the price and I'd put them in a raid array any time.

We recently had a drive failing as it hit a critical error out of nowhere and estimated out of nowhere around 37% life left. We simply got our hands on another one of these and cloned it before all hell broke loose. New drive has been working fine and we ordered another of the exact same drive (this one to replace that one in inventory, awaiting the next big uh oh moment). These drives are typically quite reliable and last a long time. They aren't always the fastest drives as we have had our share of HDD options that can transfer quicker, but it doesn't come anywhere near slow at the same time. If you are looking for affordable and dependable while also faster than your typical "green" drives and with lots of capacity, the Barracuda line is typically a solid bet.We have numerous drives ran about the various machines here, and a good number of them would be this model and fall within the 4-8TB range. Used for everything from general storage to working on video and more.**If you have found our review helpful, please vote it as helpful below so I know.

It is whisper quiet, fast transfers of data and only time will tell if it lasts. $90 bucks to safeguard my data is worth it; especially when one of my older hard drives is starting to do the clickity-click thing and it sleeps more than it is awake.I wish I could have afforded the 6TB drive but this 4TB drive seems to be the best range price wise vs storage capacity right now.Seagate has been around for a long time, they must know what they are doing. This drive is standard size but it is still a bit more sleek than my older drives.To heft it, it seems like a solid piece of newer technology...I had to go into my Windows 10 disk manager and allocate the default space it found, then it quick formatted in seconds to NTFS and it has had a constantly level data flow of over a TB to it with no problems at all. I'm sure the 256 mb cache helps a lot in that respect.I am very happy with this purchase!

I bought 3 of these drives through amazon back in late 2017. I intended to use them to clone my existing 2tb drives which were nearly full. Life got busy, the packages were left in the boxes unopened until this month (August 2020). I opened these with the understanding that I was way past a return date if something was defective with the drive - totally understood that it was my responsibility to check that they work. No contest there.But imagine my surprise to find that these are in fact NOT new hard drives. 2 of them are used. I know this because one of them fails to load claiming it has a corrupt operating system on it. The other one was partitioned in half, with a system reserved partition of 50 mb. I can't format it because this appears to also have a part of the operating system on it, and requires a low-level format option.It's understood that I took a risk waiting THAT long to even check them. That's on me. But to find that "new" drives are actually used? That's on Amazon.Update: I reached out to Seagate directly and tried to get a utility to at least perform a zero-fill on the one used drive that still worked. They pointed me to their instructions on how safely to do that - and then asked if I just wanted to exchange the drives for new ones even though these were out of warranty (expired Feb 2020). They extended the warranty until September for me, and I can return all 3 for brand new drives! Thank you Seagate! Incredible customer service!

This was advertised correctly, the images were accurate, and it’s Great. I liked it a lot. This might be a good choice if you’re looking for Hard Drives. The packaging arrived as expected and without incident. Delivery was fast and as promised. Overall, I am thrilled with the product and comfortable with the five stars. I have no problem recommending this or the seller.

I have had this hard drive for over a year and it's great. It works well and store so much. Will buy again for my next computer. It was very easy to install. It came well packaged, and shipping was fast.
