Seagate BarraCuda 2TB — ST2000LM015 Internal Hard Drive
⚠ SMR — Shingled Recording2TB 2.5" 7mm SATA 6Gb/s5400 RPM, 128MB Cache55 TB/Year Desktop Rating
The Seagate ST2000LM015 is a 2 TB 2.5-inch, 7 mm BarraCuda internal hard drive for laptops and slim systems. It is an SMR (shingled magnetic recording) drive — Seagate states this explicitly in its product manual and in its published CMR/SMR list, and it is the first thing you should know about it, because SMR changes how the drive behaves under sustained writing. Seagate lists it under part number ST2000LM015; the EAN on this listing is 0763649098318. It runs at 5400 RPM with a 128 MB cache over SATA 6Gb/s, reaches 140 MB/s maximum sustained at the outer diameter, and is rated for a 55 TB annual workload, with no published power-on-hours rating at all. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
Read this before buying: this is a shingled (SMR) drive, and it does not belong in a NAS or a RAID array. Seagate’s BarraCuda product manual prints "Recording technology SMR" for this part, and Seagate’s own public CMR/SMR list places the 4 TB and 8 TB BarraCuda in the SMR column. Shingled recording overlaps the data tracks to raise density, which is fine for reading and for ordinary desktop use, but means that sustained or random writing slows dramatically once the drive’s internal cache region fills, and that a RAID rebuild can take far longer than expected or fail outright. This is the exact scenario that caused problems for buyers who put SMR drives into NAS enclosures. The duty rating says the same thing in numbers: 55 TB per year, and Seagate publishes no power-on-hours rating whatsoever for this drive — less than a third of the 180 TB a year an IronWolf carries, and a fraction of the 550 TB of a SkyHawk AI or an Exos. If you need a drive for a NAS, a surveillance recorder, a server or any array, buy IronWolf, SkyHawk or Exos instead; all of those are CMR and publish their workload ratings and error rates. Seagate publishes no MTBF or AFR for BarraCuda, so any hours figure you see quoted for this drive is not manufacturer data, and Rescue Data Recovery is not included — Seagate’s Rescue coverage lists IronWolf, IronWolf Pro, SkyHawk, SkyHawk AI and FireCuda, not BarraCuda55 TB per year, and Seagate publishes no power-on-hours rating whatsoever for this drive — less than a third of the 180 TB a year an IronWolf carries, and a fraction of the 550 TB of a SkyHawk AI or an Exos.

Best For
✓ Desktop secondary storage for media and documents that are mostly read
✓ Archive drives written once and read many times
✓ Replacing a smaller drive in a PC that is switched off overnight
✓ Cheap bulk capacity where write performance is not critical
✓ Steam and game libraries, which are read-heavy after install
✓ Photo and video collections kept for reference rather than editing
Key Features
⚠ Shingled recording — what it means in practice
SMR overlaps data tracks like roof tiles to fit more on each platter, which is why this drive is inexpensive per terabyte. Reading is unaffected. Writing is: once the drive’s cache region fills during a long or random write, throughput can drop sharply while it reorganises tracks in the background. For a desktop drive holding a media library that is written occasionally and read often, this rarely matters. For a NAS, a RAID rebuild or continuous recording, it matters a great deal.
2TB at 5400 RPM with 128 MB of cache, in a 7 mm frame
A standard 2.5-inch unit at 26.11 x 101.85 x 146.99 mm weighing 90 g maximum, spinning at 5400 RPM per Seagate’s datasheet with a 128 MB cache and a sustained rate of 140 MB/s maximum sustained at the outer diameter — the datasheet and the product manual agree. Average latency is 6.0 ms, sector format is 512e with 4096-byte physical sectors, and load/unload is rated at 600,000 cycles. It drops into any desktop bay and any SATA port without an adapter.
Low power, quiet, cool
At 5.3 W reading and writing, 3.4 W at idle and 0.25 W in standby, this is one of the lightest electrical loads of any drive at this capacity — a direct consequence of the 5400 RPM spindle. Acoustics are 2.3 bels idle and 2.5 bels seek typical, and the operating range runs from 0 to 60 degrees Celsius case temperature.

Frequently Asked Questions
Singular Expert Insight
We will be straight about this drive, because a great many listings are not: it is shingled, and Seagate says so in its own manual. That is not a reason to avoid it, but it is a reason to buy it deliberately. SMR earns its place in read-heavy storage — a film collection, a Steam library, a photo archive — where it delivers a lot of capacity cheaply, quietly and at very low power. It is the wrong drive for a NAS, a RAID set, a surveillance recorder or anything doing sustained writes, and the 55 TB annual workload rating tells you that as clearly as the recording technology does. If an array is where this is heading, buy from our NAS hard drives range instead — every drive there is CMR with a published workload rating. And if the machine feels slow rather than full, the fix is an internal SSD for the operating system, not a faster hard drive.
Buyer’s Guide
Buy it if
You want cheap bulk capacity in a desktop for storage that is mostly read — a media, game or photo library on a machine that is switched off overnight. 2TB at low power and low noise, and you have read and accepted that this is a shingled SMR drive.
Skip it if
The drive is going into a NAS, a RAID array, a surveillance recorder or a server, or it will take sustained heavy writes — SMR is the wrong technology for all of those, and the 55 TB annual workload rating puts it out of specification anyway. Skip it too if you need a published MTBF or bundled data recovery, neither of which BarraCuda has.
Also consider
ST2000LM010 is the same 2 TB capacity as a SED-FIPS 140-2 self-encrypting drive — one digit apart and not interchangeable. ST1000LM048 and ST1000LM049 are the 1 TB 2.5-inch BarraCudas. The 4 and 5 TB 2.5-inch BarraCudas are 15 mm drives and will not fit a 7 mm bay. If the drive is going into a NAS, a recorder or anything doing sustained writes, this is the wrong family entirely — IronWolf, SkyHawk or Exos are the CMR alternatives.
