I personally would be concerned to by critical components from ebay. Its bad enough trusting the disk makers... What I have been doing for years is buying so-called enterprise HDD that have better specs and a 5 year warranty. They typically claim a x10 lower error rate then the retail drives. For SSD I look closely a the "data written" limit for the drive, once that limit is exceeded the driver will likely fail. This used to be in TiB written now getting into the PiB written. Usually you pay more for the higher write limits. There are companies that will not publish the data limit and I will not buy any SSD that hides that critical spec. You can check that a drive is new by looking at the SMART data and the powered on hours. It should be a small number. This is example output from my work horse server that runs 24x365: $ smartctl -A /dev/sda smartctl 7.3 2022-02-28 r5338 [x86_64-linux-6.3.11-200.fc38.x86_64] (local build) Copyright (C) 2002-22, Bruce Allen, Christian Franke, www.smartmontools.org === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 1 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 5 Reallocated_Sector_Ct 0x0032 100 100 000 Old_age Always - 0 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 24973 Barry |
