1 TB · M.2 2280 without factory heatsink · Samsung part MZ-V7S1T0BW
A 1 TB PCIe 3.0 NVMe SSD rated up to 3,500 MB/s read and 3,300 MB/s write, with TLC V-NAND, 1 GB LPDDR4 cache and a 600 TB write rating.

Specifications checked 11 Sept 2026Manufacturer specifications, not a hands-on test.
Rated up to 3,500 MB/s sequential read and 3,300 MB/s sequential write, with up to 600,000 random read and 550,000 random write IOPS.
Limited to PCIe 3.0 x4, so it cannot use the extra bandwidth of newer PCIe 4.0 or 5.0 slots. Peak write speed relies on the TurboWrite cache, and there is no factory heatsink.

45 specifications in 7 groups. Values are manufacturer specifications unless a row says “Measured result” or “Calculated from cited specifications”.
Decimal capacity; formatting and system use reduce available space.
Match the physical format and electrical interface to the host.
Host support and available lanes determine operation; interface generation is not an application-performance result.
Capacity row lists onboard LPDDR4 DRAM. Having DRAM is not a measured performance result.
SourceSamsung lists these as maximum dimensions. This version has no factory heatsink. · Manufacturer dimensions; confirm installation clearance.
Manufacturer calls this 3-bit MLC: three bits per cell, also called TLC. This is not two-bit MLC.
Manufacturer's stated DRAM cache capacity for this storage capacity.
This BW configuration has no factory heatsink; follow the host's cooling requirements.
Current page and revision 3 PDF identify only an in-house controller. Revision history says the controller name was removed; no fixed commercial codename is assigned.
Capacity LPDDR4 DRAM size; not the variable TurboWrite write-buffer capacity.
SourceOfficial thermal features. Not a factory heatsink enclosure or measured temperature advantage.
SourceUK capacity-specific maximum drive mass, not packaging.

SourceUp-to QD1 / one-thread value for this capacity under the manufacturer performance test setup. Not measured application latency.
SourceUp-to QD1 / one-thread result with Intelligent TurboWrite under the stated manufacturer setup. The 2 TB model's 62,000 IOPS figure does not apply to this 1 TB model.
SourcePeak write claims require the buffer. Samsung does not list the buffer capacity or post-cache write speed.
Capacity-specific warranty write threshold, not a guaranteed failure point.
Time limit, not predicted lifespan; coverage also ends at the TBW threshold and is subject to full terms.
Manufacturer coverage is subject to purchase eligibility and applicable terms. A used drive may have less coverage left.
Application class, not universal system/console compatibility.

Source1 TB column, IOmeter 1.1.0 on i7-7700K, 16 GB DDR4-2133, Gigabyte GA-Z270X, Windows 10 Pro K x64. This differs from the 32 GB performance host. Idle requires autonomous power-state operation; not constant household-use loads.
SourceUK page maximum burst-mode claim; distinct from average active, idle or constant use.
SourceUK electrical requirement, not sufficient proof of host compatibility.
SourceThe regional page supports device sleep. Host support is required; the separately published L1.2 power state is not measured laptop battery life.
SourceThe regional page labels a system-level average and a burst maximum. Hardware/configuration affect consumption. These are distinct from active read/write and idle/sleep states and are not a constant everyday load.
SourceManufacturer capabilities, not encryption enabled by default or every-host support.
SourceRequires operating-system support as stated by manufacturer.
SourceMonitoring capability, not predicted remaining life.
SourceListed internal function.
SourceManufacturer feature block lists monitoring and software/firmware updates. OS/version support and feature prerequisites require separate checking.
SourceProduct page states WWN unsupported.
SourceMeasured by the drive's S.M.A.R.T. temperature; Samsung recommends adequate airflow.
PDF non-operating range; distinct from operation. Samsung lists −45 °C for this model, lower than the −40 °C of most Samsung drives.
SourceManufacturer specifies non-condensing conditions. This environmental range is not waterproofing or an IP rating.
SourceManufacturer non-operating claim, not a device drop test.
