Samsung 870 EVO 2TB SATA SSD — 99% Health, 2024 Drive, Tested
What the bench run found
Every figure below is from this drive, tested on its own on 11 November 2026. I am not averaging across a batch or quoting a best case, and the full report for this exact serial is the first photo — read it before you buy.
| SMART overall self-assessment | PASSED |
| Health remaining (SMART attr 177) | 99% |
| Total host writes | 21.0 TB |
| Power-on hours | 8,172 |
| Reallocated sectors | 0 |
| Current pending sectors | 0 |
| Uncorrectable errors | 0 |
| SATA CRC errors | 0 |
| Full-surface read | 0 bad blocks — every LBA |
| Secure erase | ATA Security Erase Enhanced — ships blank |
What was done to it
- Securely erased with ATA Security Erase Enhanced — the drive controller's own internal erase, not a software overwrite. It ships blank and there is nothing recoverable on it. Security state afterwards: disabled and not frozen, so there is no password lock waiting for you.
- Fake-capacity probe (f3probe): genuine 2 TB. Counterfeit and reflashed drives that lie about their size are a real problem in used flash. This one was checked rather than assumed.
- Full-surface read of every LBA: 0 bad blocks (0/0/0 errors).
- No SMART extended self-test was run, so none is claimed. The full-surface read covers the same read path across the whole drive and is the stronger check. The report image says so too.
On counterfeit 870 EVOs
Fake 870 EVOs are a real problem on the used market — drives that report 2 TB and hold a fraction of it, or that are a different drive wearing a Samsung label. That is why a fake-capacity probe is part of my bench run on every drive. This one was probed and came back as a genuine 2 TB, and the full-surface read then read back all 2 TB of it with zero bad blocks — a fake cannot do that. The label photo shows the Samsung part number, model and date code rather than a stock image, and the report photo carries the serial. If you are comparing this against a cheaper one with no test evidence and a stock photo, that gap is the whole reason for the price difference.
