AI Verdict
This 1TB, 5400 RPM, 2.5-inch SATA 6Gb/s HDD is for budget-focused users needing bulk storage in a laptop or for backups, not primary system drives.
This 1TB 5400 RPM HDD is a situational fit because its 7mm thin profile and 1TB capacity are useful for specific laptop upgrades or bulk storage. However, its mechanical nature and 5400 RPM speed limit its utility for performance-critical tasks, making it best suited as a secondary drive.
If you need faster performance for your operating system or frequently accessed applications, look for a 2.5-inch SATA SSD with similar capacity.

Pros
- Offers 1TB of storage in a thin 7mm form factor, fitting most laptops.
- Operates quietly during use, according to multiple users.
- Features a 128MB cache, which helps with sequential read/write speeds.
- Installation is straightforward in various systems, including laptops and gaming consoles like the PS3.
- Lightweight design supports portable computers without adding bulk.
Cons
- As a mechanical hard drive, it's significantly slower than SSDs for operating systems or demanding applications.
- The 5400 RPM spindle speed contributes to slower data transfer, especially for large files.
- Mechanical drives consume more power than SSDs, potentially reducing laptop battery life.
- Random read/write performance (4K speeds) is poor compared to solid-state alternatives.
- Being an 'Open Box' item, there's a higher chance of receiving a DOA unit or one with prior use.
Dimension Scores
The 5400 RPM spindle speed and mechanical nature mean slower data transfer rates compared to 7200 RPM HDDs or any SSD.
While Seagate is a known brand, the 'Open Box' status introduces uncertainty, and some users reported DOA units or clicking noises indicating failure.
1TB capacity in a 2.5-inch, 7mm form factor is a good amount of storage for a laptop, especially for secondary data.
The standard 2.5-inch form factor and SATA 6Gb/s interface ensure broad compatibility with most laptops and many other devices.
Best For
- Expanding storage in an older laptop where an SSD is the primary drive.
- External backup storage for photos, videos, and documents.
- Adding capacity to devices like older gaming consoles (e.g., PS3).
- Budget-conscious users who prioritize capacity over speed for secondary storage.
Not Recommended For
- Use as a primary boot drive for an operating system.
- Users requiring fast application loading or quick file access.
- Heavy gaming or 4K video editing workflows.
Watch Out For
- Some users reported receiving DOA (Dead On Arrival) drives, indicating potential issues with 'Open Box' quality control.
- Clicking noises can be a significant warning sign of a failing drive, even in new laptops.
- Expect significant slowdowns for read/write operations on large files, with one user noting over 24 hours for defragmentation on a fragmented drive.
- The drive's 5400 RPM speed means it will be noticeably slower than a 7200 RPM HDD, let alone an SSD, for any active data use.

What Buyers Say
The most surprising feedback is the recurring mention of 'Open Box' drives being DOA or showing signs of failure, which is a significant concern for buyers. Many users appreciate its quiet operation and the slim 7mm design for laptop integration. However, the 5400 RPM speed is a constant point of contention, leading to slow performance for anything beyond basic storage. It's frequently recommended for backup or secondary storage, not as a primary drive.
“Man, I just needed more space for my old laptop, and this 'Open Box' thing was cheap. It works, but Windows takes forever to load now, and I swear I heard it click once. Hope it doesn't die on me.”
Common Praise
- Operates with very little audible noise.
- The 7mm thin profile allows it to fit into many portable computers.
- Provides 1TB of storage, which is useful for large media libraries.
- Easy to install in laptops and other compatible devices.
- Functions well as a dedicated backup drive.
Common Complaints
- Some 'Open Box' units arrived non-functional or failed shortly after installation.
- Noticeably slow for booting operating systems or running applications.
- Clicking sounds were reported, indicating potential drive failure.
- Slower data transfer speeds, particularly when handling large files.
- Consumes more battery power in laptops compared to SSDs.
Ownership Tips
- After a few weeks, the speed difference between this HDD and an SSD for daily tasks becomes very apparent.
- Monitoring drive health with tools like CrystalDiskInfo is crucial, especially for an 'Open Box' unit.
- The drive can get warm during extended file transfers, though not excessively hot.
- It's best to partition this drive for data storage only, keeping the OS on an SSD if possible.
- The quiet operation is a plus, but the slowness can be frustrating if you're used to SSDs.
Frequently Asked Questions
What is the RPM of this hard drive?
This Seagate ST1000LM035 hard drive operates at 5400 RPM.
Can I use this as my main drive for Windows?
While technically possible, using this 5400 RPM HDD as your main Windows drive will result in very slow boot times and application loading compared to an SSD.
Is this drive suitable for gaming?
This drive is not ideal for heavy gaming or installing frequently played games due to its slower read/write speeds, which can lead to longer load times.
What does 'Open Box' mean for this product?
'Open Box' typically means the product has been opened, possibly returned, and may have been tested. It can sometimes mean a higher risk of receiving a drive that is dead on arrival or has had previous use.
Will this fit in any laptop?
This drive has a 2.5-inch form factor and a 7mm thickness, which is a standard size for many laptops, especially thinner models.
Buying Guide
When looking at internal hard drives, you need to think about what you're actually going to store and how often you'll access it. For a laptop, a 2.5-inch drive is standard. If you're just dumping photos and videos you rarely touch, a mechanical hard drive like this one is fine. But if you want your computer to feel snappy, you absolutely need an SSD for your operating system and frequently used programs.
Capacity (1TB)
This is how much data the drive can hold, like a digital closet. 1TB is enough for thousands of photos and songs, or a good chunk of HD video, but it fills up fast if you're a heavy user.
Interface (SATA 6Gb/s)
This is the connection type and its maximum speed, like a highway. SATA 6Gb/s is the standard for most internal drives, but the actual speed is limited by the drive type itself, not just the highway.
Drive Type (Mechanical Hard Disk)
This tells you if it has spinning platters (mechanical) or flash memory (SSD). Mechanical drives are cheaper per gigabyte for large storage but are much slower and more fragile than SSDs, which are like super-fast, silent flash drives.
Form Factor (2.5 Inches, 7mm)
This is the physical size of the drive, like shoe size for your laptop. A 2.5-inch, 7mm drive is thin and fits in most modern laptops, but some older or thicker laptops might accommodate 9.5mm drives too.
Alternatives
If you need faster performance for your main computer drive, look for a 2.5-inch SATA SSD. For even larger bulk storage that doesn't need to be portable, consider a 3.5-inch internal HDD.
