The SanDisk 1TB Extreme Portable SSD has dropped to $249.99 at Amazon, which is $50 below its $299.99 list price. The discount is genuine and Amazon.com holds the buy box, but the same outlay buys half as much storage as SanDisk's previous-generation drive.
This is the new Extreme, model SDSSDE70-1T00-G25, and not the Extreme PRO. SanDisk charges $337.99 for the identical SKU on its own store, so Amazon undercuts the manufacturer by $88.
That gap is what makes the $299.99 anchor credible rather than decorative. The listing is not Prime-gated, so the price is the same for every shopper.
SanDisk Extreme Portable SSD specifications
SanDisk rates the drive at up to 2,000MB/s, and its datasheet is explicit that the number is a read speed. The company's own spec page puts sequential write at up to 1,700MB/s for the 1TB capacity.

The per-terabyte math works against the 1TB model
At $249.99, this drive costs $249.99 per terabyte. Every larger capacity SanDisk sells is cheaper by that measure, and so is the model it replaced.
| Drive | Price | Per terabyte |
|---|---|---|
| SanDisk Extreme 1TB, new model | $249.99 | $249.99 |
| SanDisk Extreme 2TB, new model | $429.23 | $214.62 |
| SanDisk Extreme 4TB, new model | $752.99 | $188.25 |
| SanDisk Extreme 2TB, previous model | $299.18 | $149.59 |
| Samsung T9 1TB | $252.87 | $252.87 |
The previous-generation Extreme at 2TB is the awkward entry. It is $299.18, also sold by Amazon.com, so double the capacity costs $49.19 more than this deal.
That older drive tops out at 1050MB/s instead of 2,000MB/s. It keeps the same IP65 shell and the same five-year warranty.
Stepping up inside the new line is cheaper per terabyte too. The 2TB version of the same drive is $429.23, down from $450.74.
The closest like-for-like rival is the Samsung T9 1TB at $252.87, reduced from $287.99. It uses the same USB 3.2 Gen 2x2 interface and quotes the same 2,000MB/s, so SanDisk wins that contest by $2.88.
Mechanical storage remains far cheaper per terabyte, as the recent Seagate 2TB portable hard drive deal and the WD Elements Portable 6TB discount both showed. Internal NVMe sits in between, judging by the Samsung 990 PRO 2TB deal.
What the Amazon listing leaves out
The listing never states the interface. Reaching 2,000MB/s needs a USB 3.2 Gen 2x2 port rated at 20Gbps, and a 10Gbps USB 3.2 Gen 2 port caps the link at roughly half that.
No write speed appears in the title or in any of the five bullet points. Controller, NAND type and endurance ratings are not published by SanDisk or by Amazon.
The password protection promoted in the bullets also needs a software download, according to SanDisk's datasheet. SanDisk says it works on Windows 10 and later and macOS 13 and later only.
The box holds a USB-C to USB-C cable and a quick install guide, per SanDisk's own list. No USB-A adapter is included.
Firmware history and what is not published
SanDisk posted a notice in May 2023 about a firmware issue that could make drives disconnect from a computer unexpectedly. That notice names the Extreme Portable SSD V2, the Extreme PRO Portable SSD V2 and the WD My Passport SSD.
It does not name the SDSSDE70 generation sold here. SanDisk has published nothing tying that fault to lost data, so unexpected disconnection is as far as the company's own record goes.
Flash pricing has been climbing for months, a trend covered in this report on AI demand pushing SSD prices above previous lows. Against that backdrop a $50 cut on a first-party listing is worth noting.
Amazon publishes no price history for the drive, so the claim that this is a record price has been reported rather than confirmed. The page also carries a $229.99 offer, but that one is a used unit from a marketplace seller with a single item left.
Prices were accurate on the Amazon listing as of October 8, 2026, and Amazon can change them without notice. Anyone who needs capacity more than speed should price the 2TB options first.
