Pros & Cons
Pros
- ✓ 5TB capacity, among the largest available in a 2.5-inch drive
- ✓ SATA 6Gb/s interface works with nearly any modern SATA port or USB enclosure
- ✓ 128MB cache helps with bursts of small writes
- ✓ 5400rpm spindle keeps power draw and heat low for compact builds
Cons
- ✗ Spinning HDD, far slower than SATA or NVMe SSDs despite the category

- ✗ 5400rpm makes random access and boot times sluggish
- ✗ Moving parts are more vulnerable to drops than flash storage
Manufacturer description
The Seagate BarraCuda 5TB (model ST5000LM000) fits 5TB of storage into a 2.5-inch hard drive. That makes it one of the highest-capacity drives you can get in the laptop form factor. It connects over SATA 6Gb/s, spins at 5400rpm and has a 128MB cache. Those specs favor large, low-power storage over raw speed. Note that this is a spinning hard drive (HDD), not an SSD. Sequential transfers and random access will be well behind any flash drive. It suits bulk data: game libraries you rarely launch, media collections, backups, archives and DIY external enclosures. It is a poor fit as a boot drive…

Frequently Asked Questions
Is the Seagate BarraCuda 5TB an SSD or a hard drive?
It is a mechanical hard drive. The ST5000LM000 spins at 5400rpm with a 128MB cache on a SATA 6Gb/s interface, so it is much slower than an SSD but gives far more capacity per dollar.
Will this 5TB 2.5-inch drive fit in my laptop?
Probably not. The listing marks this model as 15mm tall, and most laptops only take 7mm or 9.5mm drives. Check your bay's height limit, or use it in a desktop, a 15mm-compatible USB enclosure or a mini PC.
Is the ST5000LM000 good for gaming?
It works well for storing a large game library, but games will load more slowly than from an SSD because of the 5400rpm speed. Many buyers keep active games on an SSD and archive the rest on this drive.
What warranty comes with the Seagate BarraCuda 5TB?
The product data here does not include warranty terms. Check the product listing or Seagate's warranty lookup with the model number ST5000LM000 for current coverage.
