Seagate BarraCuda 5TB Internal Hard Drive HDD – 2.5 Inch SATA 6Gb/s 5400 RPM 128MB Cache for Computer Desktop PC (ST5000LM000)

An easy install and great value, the drive performs well with short file copies between the Barracuda and an SSD (Hynix). Note it IS 5400 RPM, NOTE IT IS 128 meg CACHE. These are key factors in your drive purchase, performance vs. battery life. I've found it to be especially efficient with file or file selects under 2 GB for copies between the drives on the same laptop system. File copies and backups via a 1 gb network connection work great most of the time, and the read/writes are over 60 meg/sec write via the network to another 7200 RPM drive (WD Blue WZEZ), even 100 meg/sec to a (boot) SSD on the network. Expect the benchmarks to be correct, value at a good performance rate. As stated smaller transfers also have great burst over the 1 gb network, with less than 1.5 Gb copying in under 6-10 seconds. This drive does well on smaller copy transfers than larger files due to its 128 meg cache. It's a great second system and backup drive for an SSD (boot) drive based system, on a laptop or desktop. This isn't a workstation drive unless you work backups (Win 10 File history is FAST, as is Win 7 type backup), in which its value speaks for itself. I'd recommend this drive based on price and performance for all things considered. AS-SSD benchmark is reported as 130 meg/sec read, 120 meg/sec write on 4k transfers. It's consistent with other tested benchmarks for the same drive/model. 5 stars, not to mention I have a successful history with Seagate products! TC

I didn’t realize this drive was used when I purchased it, but it has been working well so far. I installed it in my eufy HomeBase to store local video recordings from my security cameras, and setup was quick and smooth. Performance has been stable, and it handles continuous recording without issues. Despite being pre-owned, it has performed reliably for my needs and serves as a good storage solution.

All is good! I Ordered this 5TB hard drive for our new Eufy camera system. After the drive was formatted ONE TIME, it showed only 1.13 TB was available for storage and the rest of this drive was "USED". I have since learned that this is just the strange way Eufy shows that 4.77 TB is "USEABLE: but not necessarily USED.

Seagate used to reserve the "Barracuda" label for their higher performance drives. Now they're sticking the Barracuda name on everything and are now calling Barracuda "Pro" drives for once was a standard Barracuda performance HDD. So I thought I was getting a higher performance drive since it had the Barracuda name on it and was willing to pay more for that. However, what I come to find out is that this Barracuda HDD is nothing special over their external USB 3.0 "OneTouch" or "Backup Plus" portable HDDs. The price on this 2.5in 5TB internal Barracuda HDD is currently $135-150. You can purchase a Seagate 5TB USB 3.0 portable OneTouch HDD for $100. Now here's where it gets interesting. If you crack open the case of Seagate's external portable "OneTouch" HDD, you will come to find out it's the exact same model Barracuda 5400 RPM 128MB cache 2.5in HDD as this internal 2.5in Barracuda HDD but costs much less. However, opening up the case of their portable HDDs would void the warranty, but this particular listing doesn't have a manufacturer warranty so what do you have to lose? Purchase their portable "OneTouch" 5TB HDD for $40-$50 less, crack open the case and remove the HDD if you need an internal HDD. The portable version is this exact same Barracuda model HDD, with a SATA 3 interface and plugged into a SATA3 to USB interface, and they give you a good quality USB cable and HDD carrying case to boot. When I found out this Barracuda drive had no additional performance gains, and no manufacturer warranty as I verified on Seagate's website, I returned it and purchased their portable HDD and cracked open the case. Now I not only have the exact same HDD which cost significantly less, I also gained an extra USB 3.0 HDD enclosure case and a nice quality included USB cable. Take that bad Seagate marketing!

What makes this such a cheap 2.5-inch 5TB HDD is a non-standard data recording method called "Shingled Magnetic Recording" or "SMR". To quote Google AI, "When comparing a Seagate Barracuda with SMR (Shingled Magnetic Recording) to one with PMR (Perpendicular Magnetic Recording), the key difference is that the SMR drive will generally have significantly slower write speeds due to its overlapping track design, while the PMR drive offers faster write performance, making it better for write-intensive tasks, even though the SMR drive might have a higher storage capacity at a lower price point." What that means is, it's good for data that you put on it once and never delete or update again, and slow for handling data that needs to be rewritten. I had to use mine for rewriting due to a lack of storage elsewhere, but every time I try to delete the latest version of the Unreal Engine 5 and replace it with the newest one, it makes the drive slow to a crawl. I have to constantly give my 5TB Barracudas down time and defrag them whenever I do big delete or write operation on them. I even had to open my computer case and point a full-sized desk fan at them whenever I run them just to keep them from overheating. Bottom line: Get this if you need a cheap, high-capacity 2.5-inch 5TB HDD you will never rewrite data to. But if you need drives to store data you want to rewrite on a regular basis, get a CMR/PMR HDD or an SSD.
