Our take on the Dogfish 512GB 2.5" Internal SSD SATA III

The Dogfish 512GB is a budget 2.5-inch SATA III internal SSD built on 3D NAND, rated for up to 500MB/s sequential reads and writes. It fits laptops and desktops with a standard SATA bay and works as a cheap way to revive an older machine or add fast storage. At $69.99 at Newegg.com as of November 3, 2026, it is the only new price listed, so there is no recent range to compare it against. The 3-year parts warranty and 1,000,000-hour MTBF are typical for the class.

Questions and answers

Is the Dogfish 512GB SSD worth it?
At $69.99 at Newegg.com as of November 3, 2026, it is priced like a budget SATA drive. It makes sense if you have a SATA bay and want a cheap speed-up over a hard drive. If your machine supports NVMe, a comparable NVMe drive usually costs similar and runs much faster.
Will it fit my laptop?
It is a standard 2.5-inch drive, 100mm long, 69.85mm wide and 6.8mm thick, so it fits most laptops and desktops with a 2.5-inch SATA bay. Check that your laptop takes a 2.5-inch drive rather than only an M.2 slot.
How fast is it compared with an NVMe SSD?
Dogfish rates it at up to 500MB/s read and write, which is near the practical limit of SATA III. Typical NVMe drives reach several thousand MB/s, so this is a budget upgrade, not a performance part.
What is the endurance rating?
Dogfish does not publish a TBW (terabytes written) figure for this model, only a 1,000,000-hour MTBF. For light everyday use that is fine; for heavy sustained writes, a drive with a stated endurance rating is safer.
What comes in the box?
Expect the drive itself. The listing does not mention a SATA cable, mounting screws or a 2.5-to-3.5-inch bracket, so plan to reuse your existing hardware or buy them separately.
When is it cheapest?
Only one new price, $69.99 at Newegg.com as of November 3, 2026, is listed, so there is no recent low to time a purchase against. Watch for SSD sales around major shopping events.
Where is the Dogfish 512GB 2.5" Internal SSD SATA III cheapest?
