Quick Answer+
Quick Answer: The Seagate Barracuda 1TB (ST1000DM010) is a budget desktop hard drive priced at $40-55. It’s the only Barracuda that uses CMR technology (not SMR), making it more reliable for boot drives and write-heavy tasks than larger Barracuda models. With 7200 RPM and 64MB cache, it delivers up to 210 MB/s sequential reads. Best for: budget desktop storage, secondary drives, or users who specifically need CMR at low capacity. For more storage, consider an SSD or the 2TB Barracuda (but note the 2TB uses SMR).
The Seagate Barracuda 1TB (ST1000DM010) holds a unique position in the Barracuda lineup. While most Barracuda drives use SMR (Shingled Magnetic Recording) technology, the 1TB model is one of the few that still uses traditional CMR (Conventional Magnetic Recording). This makes it a compelling choice for users who need reliable write performance at an entry-level price point.
However, in 2026, a 1TB hard drive faces stiff competition from similarly-priced SSDs. This guide will help you understand when the Barracuda 1TB makes sense and when you should consider alternatives.
Why Choose the Barracuda 1TB in 2026?
With SSDs becoming increasingly affordable, you might wonder why anyone would buy a 1TB HDD. Here are the legitimate reasons the Barracuda 1TB still makes sense:
1. CMR Technology at Low Cost
The 1TB is the only Barracuda with CMR. If you need a small, reliable CMR drive for a specific application (like a boot drive in a legacy system or a small RAID array), this is your cheapest option from Seagate.
2. Budget Constraints
At $40-55, the Barracuda 1TB is $15-25 cheaper than a comparable SSD. For extremely budget-conscious builds, this savings can go toward other components.
3. HDD Compatibility Requirements
Some older systems, industrial applications, or specific software may require traditional HDDs. The Barracuda 1TB fills this niche.
4. Secondary/Backup Storage
As an inexpensive secondary drive for documents or backups, the 1TB offers reasonable capacity at minimal cost.

Why the 1TB Barracuda Uses CMR (And Why It Matters)
The Seagate Barracuda 1TB is special because it’s one of the only consumer Barracuda drives that uses CMR (Conventional Magnetic Recording) instead of SMR.
What does this mean for you?
- Consistent write speeds — No slowdowns during sustained writes
- Better for boot drives — OS installations involve lots of random writes
- RAID compatible — Won’t cause rebuild failures like SMR drives
- Suitable for light NAS use — Though IronWolf is still better
The trade-off? The 1TB Barracuda has a smaller 64MB cache compared to the 256MB cache on larger (SMR) models. This is because SMR drives need larger caches to buffer writes before reorganizing data on the shingled tracks.
Performance Benchmarks
Based on real-world testing, the Seagate Barracuda 1TB ST1000DM010 delivers:
| Test | Result |
|---|---|
| Sequential Read | 200-210 MB/s |
| Sequential Write | 190-200 MB/s |
| Random 4K Read | 1.2-1.5 MB/s |
| Random 4K Write | 1.0-1.4 MB/s |
| Average Access Time | ~12ms |
These numbers are typical for a 7200 RPM desktop HDD. Sequential speeds are respectable, but random 4K performance is where all mechanical drives struggle compared to SSDs.

Model Number Variations
You may encounter different model numbers for the Seagate Barracuda 1TB. Here’s what they mean:
| Model Number | Description |
|---|---|
| ST1000DM010 | Standard retail packaging |
| ST1000DMZ10 | Frustration-free (Amazon) packaging |
| ST1000DM003 | Older generation (pre-2016, also CMR) |
| ST1000DM014 | Newer variant with SMR (avoid if you need CMR) |
Important: The ST1000DM014 variant uses SMR technology despite being 1TB. Always verify you’re getting the ST1000DM010 if you specifically need CMR.
Contact Start-Stop Technology
Unlike larger Barracuda models that use load/unload ramps, the 1TB Barracuda uses Contact Start-Stop (CSS) technology. This is an older parking mechanism where the heads park directly on a landing zone on the platters.
What this means for you:
- 50,000 load/unload cycles (vs 600,000 for larger models)
- Slightly more wear during frequent power cycles
- Fine for typical desktop use with the PC running for hours at a time
- May wear faster if used in applications with frequent power on/off cycles
For most users, this is a non-issue. The drive is still rated for years of typical desktop use.
Seagate Barracuda 1TB Price History
The Barracuda 1TB has maintained relatively stable pricing over the years:
- 2020: $45-50
- 2022: $40-50 (post-pandemic normalization)
- 2024: $40-55
- 2026: $40-55 (current)
Unlike SSDs which have dropped dramatically in price, 1TB HDDs have stayed relatively flat. This makes the value proposition increasingly questionable — why pay $45 for a 1TB HDD when a 1TB SSD costs $60-80?
When to Buy (and When to Skip)
Buy the Barracuda 1TB if:
- You specifically need CMR technology at minimal cost
- You’re building a budget RAID array with small drives
- You have an older system that can’t use NVMe SSDs

Frequently Asked Questions
The Seagate Barracuda 1TB (ST1000DM010) uses CMR (Conventional Magnetic Recording). This is unique among Barracuda drives — most 2TB and larger models use SMR. The CMR technology makes the 1TB model better suited for boot drives and write-intensive workloads.
For basic computing (documents, light media, web browsing), 1TB can be sufficient. However, modern games average 50-100GB each, and 4K media files are enormous. Most users should consider 2TB or 4TB for future-proofing. The 1TB Barracuda works best as a secondary drive alongside an SSD.
Yes, the 1TB Barracuda works as a boot drive, and its CMR technology handles OS writes better than SMR models. However, in 2026, we strongly recommend an SSD for your boot drive — the performance difference is dramatic, and 1TB SSDs are affordable at $60-80.
The 1TB model has 64MB cache while the 2TB has 256MB because they use different recording technologies. SMR drives (like the 2TB) need larger caches to buffer writes before reorganizing data on shingled tracks. CMR drives (like the 1TB) don’t need as much cache since writes go directly to the platters.
Seagate rates the Barracuda 1TB for 55 TB/year workload with a 2-year warranty. In typical desktop use, these drives commonly last 3-5+ years. Reliability depends on operating temperature (keep below 45°C), avoiding physical shocks, and using a quality power supply.
