Grading system

Why the grade matters

Buying used enterprise hardware is not like buying a used laptop. The parts that fail are predictable: drive spindles, disk platters, fan bearings, capacitors. A drive that came out of a server with zero power-on hours has not had the opportunity to fail yet. That is the entire argument for buying pulled stock, and it is why we grade it separately rather than calling it "new".

What "Brand New Pulled" actually means

Our highest grade is not factory-sealed stock, and we never describe it as such. It means:

• The unit was pulled from a decommissioned production server or storage array
• It has never been powered as a sale unit — power-on hours read zero
• Reallocated sector count reads zero
• Capacity is at full rated specification; no degradation
• No cosmetic wear from handling

It reads as new. What makes it valuable is different: you know it came out of a real datacentre environment, you know it has not been sitting in a retailer's cupboard, and you have the serial history to prove where it came from.

If you need genuinely sealed, never-opened factory stock, tell us — it is rare and we do not usually hold it.

Disclosing the awkward facts

Two things we tell every buyer up front:

• Power-on hours are reported per unit, not per model. A lot graded Brand New Pulled reads zero on every unit in it. A used lot shows its real numbers, which vary.
• Failed units are removed, not discounted into the lot. A drive that fails our bench goes to spares or is scrapped. It never enters a tested lot at a lower price.

Grading table

| Grade | 中文 | What it means |

| --- | --- | --- |

| Brand New Pulled | 全新拆机 | Pulled from production, zero power-on hours, full capacity |

| Refurbished | 翻新整机 | Fully disassembled, tested, rebuilt, wear parts replaced |

| Used — Grade A | 二手 A 级 | Light use, cosmetic wear only, tested and working |

| Used — Grade B | 二手 B 级 | Moderate use, visible wear, tested and working |

| Used — Grade C | 二手 C 级 | Heavy use, cosmetic condition poor, tested and working |

| For Parts | 配件机 | Not functional, sold for spares and repair stock |

What we test before a unit is listed

Drives and SSDs

• Full SMART attribute read, retained with the unit
• Reallocated, pending and uncorrectable sector counts
• Power-on hours, power cycles, spin-up count
• Overall health percentage
• Write and read surface test on a sample of the capacity
• For SSDs: NAND wear percentage, total data units written, media errors

Servers and chassis

• Boot test with the target operating system where applicable
• CPU and memory population verified against the SKU
• Fan health and PSU redundancy confirmed
• RAID controller and backplane presence checked
• Cosmetic grade photographed

Network equipment

• Power-on and boot to a clean configuration
• Port count and optic compatibility confirmed
• Fan and thermal behaviour checked under load where units are in stock

The warranty that comes with it

Warranty is stated on every listing and honoured within its term without argument. What it covers, how long it lasts and what it excludes is set out on the warranty page.
