ST1000DM010: CMR Specs, Reliability and Buying Guide
ST1000DM010 is the older 1TB desktop BarraCuda that many buyers seek because it uses CMR. That advantage must be weighed against age, marketplace condition, warranty source and SMART history.
Quick answer
ST1000DM010 is a 1TB, 3.5-inch, 7,200 RPM CMR desktop HDD with 64MB cache and a rated maximum sustained speed around 210MB/s. It can handle repeated rewrites more predictably than DM014, but a non-new unit with unknown history is not automatically a good purchase.
Exact model data
ST1000DM010 and modern purchase alternatives
| Model | Type | Status | Form factor | Height | Recording | RPM | Cache | Rated speed | Best fit |
|---|---|---|---|---|---|---|---|---|---|
ST1000DM010 | Desktop HDD | Older model | 3.5-inch | 20.2mm | CMR | 7,200 | 64MB | 210MB/s | Repeated rewrites when a verified new or healthy unit is available |
ST1000DM014 | Desktop HDD | Current model | 3.5-inch | 20.2mm | SMR | 7,200 | 256MB | 220MB/s | Single-PC secondary storage and mostly-read libraries |
ST1000DM003 | Desktop HDD | Legacy | 3.5-inch | 26.1mm | CMR | 7,200 | 64MB | Generation-specific | Existing-system identification, not default new purchase |
ST1000DM004 | Desktop HDD / SED | Legacy security variant | 3.5-inch | 26.1mm | CMR | 7,200 | 64MB | Generation-specific | Existing-system identification and exact replacement |
CT1000BX500SSD1 | SATA SSD | Current alternative | 2.5-inch | 7mm | NAND | N/A | Controller-managed | Up to 540MB/s | Low-cost boot and application upgrade |
CT1000MX500SSD1 | SATA SSD | Current alternative | 2.5-inch | 7mm | NAND | N/A | DRAM-equipped | Up to 560MB/s | Higher-quality SATA boot-drive replacement |
The CMR specification does not prove that a used or renewed unit is healthy. Condition and verified history remain separate purchase factors.
Live catalogue
ST1000DM010 offers separated by condition
Only fresh exact-model products are eligible. New, renewed and used offers are kept in separate condition records. Featured prices are shown when Amazon exposes them; exact products with no buy box can still appear as buying options. Mixed variations, wrong form factors and model substitutions are rejected.

Why ST1000DM010 still attracts searches
DM010 combines a familiar 1TB capacity with CMR recording and 7,200 RPM operation. Buyers compare it with DM014 because CMR can behave better under repeated rewriting. The model also appears in many existing desktops, so a large share of searches concern replacement, detection, firmware and health rather than a brand-new purchase.Exact specification profile
The drive is a 3.5-inch SATA desktop HDD with 1TB capacity, 7,200 RPM rotation, 64MB cache and a rated sustained transfer figure around 210MB/s. It belongs to an older BarraCuda generation. The base model may be followed by a production suffix such as ST1000DM010-2EP102; the suffix should be retained when researching firmware or manufacturing details.CMR advantage without mythology
CMR writes tracks conventionally and avoids the shingled-track reorganization associated with DM014. That makes it a better technical fit for frequent large rewrites. It does not make the drive equivalent to a NAS or enterprise product, remove desktop workload limits, or guarantee that an old unit is reliable.New-old-stock versus used
A sealed or genuinely new-old-stock drive is different from a server pull, seller-refurbished or renewed unit. Packaging alone is not enough. Verify the serial number, warranty route, seller history and return policy. Marketplace wording such as “tested working” often indicates used hardware even when the condition badge is unclear.SMART evidence to request
Ask for the full SMART report, not only a green health percentage. Review power-on hours, power-cycle count, reallocated sectors, current pending sectors, offline uncorrectable sectors and interface CRC errors. A zero value in a screenshot can still be unhelpful if the serial number is hidden or the report does not match the offered drive.Reliability claims need context
A universal failure-rate claim for DM010 would ignore age, sample, workload and condition. A drive already operating reliably in a lightly used desktop is not the same risk as an anonymous marketplace pull. Use exact history and current diagnostics rather than a family reputation or isolated forum report.When the purchase can make sense
DM010 can make sense when the model is specifically required, the unit is verified new or low-hour, warranty and return rights are clear, and the price is well below a modern SSD or larger HDD. It can also be useful as a non-critical lab or compatibility replacement when another copy of the data exists.When to walk away
Walk away when the seller hides the model, condition or SMART data; when the drive has pending or uncorrectable sectors; when price approaches a new SSD; or when the intended role is an important NAS array. CMR is not a reason to accept uncertain history.Replacement strategy
For an aging desktop system, a 1TB SATA SSD is often the best boot-drive replacement. For bulk storage, compare a current 2TB HDD. For a laptop, do not buy DM010; it is physically too large. For NAS, choose an appropriate CMR NAS drive rather than matching the old desktop model merely because it is CMR.Cloning an existing DM010
Clone only when the source is stable enough to read and the important data is already backed up. If the drive clicks, disconnects or reports serious SMART warnings, repeated full-disk cloning attempts may worsen the situation. Consider data-recovery imaging practices or professional help for irreplaceable data.Firmware and exact suffixes
Do not install firmware based only on “BarraCuda 1TB.” Use Seagate’s download finder with the exact model and serial number. Firmware intended for another model or platform can make a recoverable situation worse. Back up first and avoid firmware experiments on a drive with active mechanical symptoms.DM010 versus DM014 decision
Use the dedicated comparison page to separate recording technology from purchase condition. A verified DM010 can be preferable for sustained rewriting; a new DM014 can be preferable for light desktop storage when the alternative is an old or unsupported DM010.How Cloudzat evaluates BarraCuda 1TB listings
Cloudzat treats the model number as the identity. ST1000DM014, ST1000DM010 and ST1000LM048 are not interchangeable specifications, even though all may be advertised as a 1TB BarraCuda. Recording method, form factor, height, cache, age and suitable workload are attached only after an exact model match.
The catalogue stores new, renewed, refurbished and used offers separately. It rejects mixed-capacity variations, products whose form factor conflicts with the exact model, SSD and HDD substitutions, unrelated Seagate families, external products, accessories and multipacks. A low price is not treated as a good value until model, condition, seller and warranty source are clear. Important data still requires an independent backup.
