Western Digital WD Blue SA510 1 TB, five bullets of recopied attributes review
A 560 MB/s reading figure in a title that does the whole job, on a page whose five bullets are recopied attribute rows — one of them stating that an internal SSD has no wireless network.
The title carries everything this page knows: 1 TB, SATA III at 6 Gb/s, 2.5 inch at 7 mm (0.28 in), up to 560 MB/s, and the part number WDS100T3B0A. Five hundred and sixty megabytes a second is as close to what the SATA interface itself permits as this family gets, and the previous-generation WD Blue beside it publishes the same figure.
Then come the bullets, and they are a curiosity. “Storage Capacity: 1 TB”. “Drive Interface: SATA”. “Drive Type: Internal”. “Form Factor: 2.5"". Four attribute rows, each repeating something the title already said. And the fifth: “Wireless LAN: No”.
An internal solid-state drive has no wireless network. The row is a scraped attribute from a form built for a different kind of product, carried onto this page and published. It is harmless and it is also the clearest possible sign of how the page was assembled: five fields filled from a database, none of them written for a buyer.
What that costs is everything a drive comparison depends on. No sequential write figure, so the slower of the two directions is unstated. No TBW, so the writing the drive is rated for is unknown. No MTBF or MTTF, so there is no population statistic either. No warranty term of any length.
The description adds two useful things the bullets do not: the drive is made in 2.5-inch and M.2 form, and Acronis True Image for Western Digital is included for backup and cloning. The M.2 note deserves a warning: an M.2 SATA stick looks exactly like an M.2 NVMe one once fitted, and a board manual rather than a photograph settles which a slot accepts. This listing is the 2.5-inch drive.
On October 26, 2026 Amazon.com had no featured offer for it; third-party sellers listed it at $274, which was $21 below the previous-generation WD Blue — a drive that publishes a write figure, a written total, a population statistic and the methods behind both.

Where it holds up, and where it stops
Strengths
Up to 560 MB/s reading, as close to the SATA interface ceiling as this family gets
$21 below the previous-generation WD Blue on Amazon.com on October 26, 2026
Publishes the 7 mm (0.28 in) height, which a thin laptop bay depends on
Acronis True Image for Western Digital backup software is named in the description rather than merely implied
The title alone carries capacity, interface revision, form factor, height, speed and part number
Compromises
Five bullets that repeat the title, including "Wireless LAN: No" on an internal solid-state drive
Third-party sellers only on Amazon.com on October 26, 2026, at $274, and no warranty term published
No writing figure, so the slower of the two directions is never quantified
Neither a written total nor a population statistic, where the previous-generation WD Blue on this shelf publishes both with their methods
The M.2 version shares this name, and an M.2 SATA stick is indistinguishable from an NVMe one once fitted
Specifications
Capacity
1 TB — printed in the title and repeated in the first bullet, in the maker’s unit and reported here in that unit without conversion
Form factor
2.5-inch — printed in the title and repeated in the fifth bullet. The description adds that the drive is available in 2.5-inch or M.2 form, and this listing is the 2.5-inch one
Height
7 mm (0.28 in) — printed in the title as 2.5"/7mm, which is the figure a thin laptop bay depends on
Stated sequential read figure
Up to 560 MB/s — printed in the title, matched by the previous-generation WD Blue beside it; the Gigastone pack publishes 550
Stated sequential write figure
Not published on the listing — no writing rate appears in the title, in any of the five bullets or in the description, so only one of the two directions is quantified
Stated random IOPS
Not published on the listing — no figure in IOPS appears anywhere on the page, as on the other two listings here
TBW rating
Not published on the listing — no total in terabytes written appears. The previous-generation WD Blue on this shelf publishes up to 600 TB with the method behind it
Stated MTBF
Not published on the listing — no figure in hours appears, in either the MTBF or the MTTF form. The previous-generation WD Blue on this shelf publishes 1.75 million hours of MTTF
DRAM cache presence
Not published on the listing — no memory chip on the drive is claimed and no arrangement for working without one is named
Controller family
Not published on the listing — no controller and no memory type is named in the title, the five bullets or the description
Warranty length
Not published on the listing — no term of any length appears anywhere on the page, as on the WD Blue 3D NAND; only the Gigastone pack names one

The questions that come up before an order
Why does the page say "Wireless LAN: No"?
It is a scraped attribute from a form built for a different kind of product. No internal solid-state drive has a wireless network. The other four bullets likewise repeat something the title already states.
What warranty does it carry?
The listing does not say. No term of any length appears in the title, the five bullets or the description. The previous-generation WD Blue on this shelf publishes none either; only the Gigastone pack names three years.
Is this the M.2 version?
No. The title gives 2.5 inch at 7 mm (0.28 in). The description notes that the drive is also made as an M.2 stick, and an M.2 SATA stick looks exactly like an M.2 NVMe one once fitted, so a board manual rather than a photograph settles which a slot accepts.
Against the rest of the network and storage gear

Western Digital WD Blue SA510 1 TB, five bullets of recopied attributes
$274
1 TB — printed in the title and repeated in the first bullet, in the maker’s unit and reported here in that unit without conversion
2.5-inch — printed in the title and repeated in the fifth bullet. The description adds that the drive is available in 2.5-inch or M.2 form, and this listing is the 2.5-inch one
7 mm (0.28 in) — printed in the title as 2.5"/7mm, which is the figure a thin laptop bay depends on
Up to 560 MB/s — printed in the title, matched by the previous-generation WD Blue beside it; the Gigastone pack publishes 550
1 TB — printed in the title, in the maker’s unit and reported here unchanged. The description separately names capacities up to 4 TB, which belongs to the range rather than to this drive
2.5-inch — printed in the title alongside the height
7 mm (0.28 in) — printed in the title as 2.5"/7mm, which is the figure a thin laptop bay depends on
Up to 560 MB/s — printed in the title and repeated in the description, matched by the newer SA510 beside it
1 TB — printed twice in the title, in the maker’s unit and reported here in that unit. The second bullet separately names up to 4 TB, which is the ceiling of the range rather than this drive
2.5-inch — printed in the title, which also names laptops and desktop machines as the intended homes for the drive
Not published on the listing — no thickness in millimeters appears, on a page that names laptops in its title and its second bullet
Up to 540 MB/s — printed in the title. No bullet repeats it, and the first describes the effect rather than the figure
1 TB — printed in the title, in the maker’s unit and reported here in that unit. The third bullet separately names a 250 GB variant, which is a different drive in the same range
2.5-inch — printed in the title beside the interface revision
Not published on the listing — the format is given in inches and no thickness follows it in the title or in the six bullets
Up to 560 MB/s — printed in the title and repeated in the second bullet, where it sits beside a multiple against spinning drives
What separates the models, in network and storage gear
If price decides: Crucial BX500 1 TB, three years and a named encryption standard, at $195.
Highest Stated sequential read figure in the table: Samsung 870 EVO 1 TB, whose written total belongs to a smaller drive (Up to 560 MB/s — printed in the title and repeated in the second bullet, where it sits beside a multiple against spinning drives).
The buyer this one serves, among network and storage gear
A machine where the reading figure is what matters and endurance will not be audited.
What this one costs among network and storage gear
Amazon reports what buyers took in the month before this page was last checked: at least 200.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.
Sources
Specifications: the manufacturer sheet for network and storage gear and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
1 TB · 2.5-inch · up to 540 MB/s read · dynamic write acceleration named · 256-bit hardware encryption to three named standards · three-year limited warranty · no write figure, no TBW, no MTBF
A one-terabyte drive that publishes a term, a named write acceleration mechanism and three encryption standards by name, and that never quantifies writing or endurance.
Best for: A machine where encryption to a named standard is a requirement and the drive will be read from far more than it is written to.
four 1 TB drives · 2.5-inch at 7 mm (0.28 in) · up to 550 MB/s · TLC 3D NAND with SLC caching · power loss protection and ECC named · three-year replacement
Four 1 TB drives for a NAS array, and the only listing on this shelf that names power loss protection — with the word TBW on the page and no figure behind it.
Best for: Filling a four-bay enclosure in one order with drives that name power loss protection and a three-year term — once the pack is back in stock.
2 TB · 2.5-inch · SATA III · up to 540 MB/s read · up to 500 MB/s write · three-year warranty ending at a written total the page never states · no MTBF · no controller named
A two-terabyte drive whose warranty is explicitly limited by a written total, and whose page never says what that total is.
Best for: A desktop machine or a laptop needing two terabytes on this interface, bought by someone who will ask for the written total before relying on the term.
