Enterprise NVMe SSD, U.2/E1.S/E3.S, 3.84-30.72 TB

具体是哪种外形规格？U.2 15mm / U.3 / E1.S（请注明5.9、8.01、9.5、15还是25mm载板）/ E1.L 9.5mm / E3.S 7.5mm / E3.S 2T 16.8mm / M.2 2280 / M.2 22110？

Exact form factor and thickness: U.2 15mm / U.3 / E1.S (state 5.9, 8.01, 9.5, 15 or 25mm carrier) / E1.L 9.5mm / E3.S 7.5mm / E3.S 2T 16.8mm / M.2 2280 / M.2 22110?

E1.S thickness and E3.S vs E3.S 2T are non-interchangeable; the most common mis-ship in EDSFF.

标称容量多少TB？请同时说明是否为超配型号（如3.2TB对3.84TB），并给出OP比例。

Rated capacity in TB, and is this the over-provisioned SKU (e.g. 3.2TB vs 3.84TB)? State the OP ratio.

3.2 vs 3.84TB at the same NAND count is the endurance/OP tell; also the first place fake capacity shows up.

PCIe几代、几通道？Gen3 x4 / Gen4 x4 / Gen5 x4 / Gen5 x8？是否支持双端口（2x x2）？

PCIe generation and lane width: Gen3 x4 / Gen4 x4 / Gen5 x4 / Gen5 x8? Dual-port (2x x2) supported?

Gen5 drives need chassis airflow and often backplane retimers; dual-port is required for HA arrays.

DWPD是多少？是按3年还是5年质保期计算的？请同时给出PBW/TBW数值。

DWPD rating — measured over 3 years or 5 years? Also give the absolute TBW/PBW figure.

DWPD over 3 years is ~1.67x the same drive quoted over 5 years. Without the period, DWPD is meaningless.

闪存是TLC还是QLC？多少层？是原厂正片、白片还是黑片（降级片）？请明确。

TLC or QLC? Layer count? Is the NAND original-grade die, downgraded/'white' die, or ungraded 'black' die?

Downgraded and ungraded die is the single largest quality variable in PRC module-maker quotes.

闪存颗粒来自哪家晶圆厂？长江存储、三星、SK海力士/Solidigm、美光、铠侠还是闪迪？贵司是自有晶圆还是外购颗粒封装？

Which fab supplies the NAND die: YMTC, Samsung, SK hynix/Solidigm, Micron, Kioxia, or Sandisk? Do you own the wafer supply or buy die and assemble?

Separates a real manufacturer from a module assembler, and determines Entity List exposure and allocation risk.

主控芯片具体型号是什么？是自研主控（如大普微DP系列）、国产第三方（联芸、英韧、得一微、忆芯、得瑞领新）还是Marvell/Phison等？

Exact controller model. Self-developed (e.g. DapuStor DP-series), domestic third-party (Maxio, InnoGrit, YEESTOR, Starblaze, Derui Lingxin), or Marvell/Phison etc.?

Controller identity is the best single proxy for whether a drive is genuinely enterprise-class.

是否板载独立DRAM缓存？容量多少GB？还是无缓存（DRAM-less / HMB）方案？请提供PCB正反面高清照片。

Does the drive have onboard DRAM? How many GB? Or is it DRAM-less / HMB? Send high-resolution photos of both PCB sides.

DRAM-less drives sold as enterprise is the top NVMe fraud. Rule of thumb: ~1GB DRAM per 1TB NAND. HMB is not acceptable in a server.

掉电保护是硬件电容式还是仅固件式？如为硬件，请说明电容类型（钽电容/MLCC）、数量，并在PCB照片中指出位置。是否通过JESD218掉电测试？

Is PLP hardware capacitor-based or firmware-only? If hardware, state capacitor type (tantalum/MLCC), count, and point them out in the PCB photo. Has it passed JESD218 power-cycling test?

Firmware-only 'PLP' protects metadata at best. Cap count is physically verifiable from a photo — the cheapest anti-fraud test available.

最大工作功耗多少瓦？空闲功耗多少？是否支持NVMe电源状态限制（可配置功耗上限）？

Maximum active power in watts, and idle power? Does it support configurable NVMe power-state limiting?

A 25-35W Gen5 drive x24 changes chassis thermal design. Sellers routinely omit this and the buyer discovers it at integration.

请提供稳态（预处理后至少4小时）4K随机写IOPS，以及99.99%分位读延迟（微秒）。不要提供峰值/突发数据。

Give steady-state 4K random-write IOPS after at least 4 hours of preconditioning, plus 99.99th-percentile read latency in microseconds. Not burst figures.

Consumer-grade drives look fine for 60 seconds and collapse at steady state. This question alone eliminates most fake enterprise quotes.

货品状态是原厂全新、原厂返修（recertified）、拆机件还是工程样片（ES/QS）？请书面确认，并注明是否为矿盘或数据中心退役盘。

Is the stock factory new, vendor-recertified, pulled/used (拆机件), or an engineering/qualification sample (ES/QS)? Confirm in writing, and state whether it is ex-mining or ex-datacentre decommissioned.

Engineering samples carry no warranty and unstable firmware. Get this in writing so a mis-statement is a contractual breach, not a misunderstanding.

出货时SMART的通电时间、通电次数、已写入总量(TBW)和百分比寿命(Percentage Used)分别是多少？请随机抽3片提供smartctl -a完整截图。

At shipment: SMART power-on hours, power cycle count, total host writes (TBW), and Percentage Used? Send full `smartctl -a` screenshots for 3 randomly selected units.

Zero hours with a high power-cycle count is the classic reset signature — no real new drive has 2400 cycles at 2 hours.

固件是原厂通用版还是Dell/HPE/联想/浪潮等OEM定制版？OEM版能否刷回通用固件？请提供固件版本号。

Is the firmware generic vendor firmware or an OEM build (Dell/HPE/Lenovo/Inspur)? Can OEM firmware be reflashed to generic? Give the firmware revision string.

OEM-locked drives may refuse to initialise, throw warranty warnings, or be unsupported in a different chassis. Price difference is large and legitimate.

是否支持TCG Opal 2.0或Ruby自加密？是否有FIPS 140-3证书？如有请提供NIST证书编号。是否支持NVMe Format NVM和Sanitize（crypto erase / block erase）？

TCG Opal 2.0 or Ruby SED support? FIPS 140-3 validated — if so give the NIST certificate number. NVMe Format NVM and Sanitize (crypto erase / block erase) supported?

FIPS certificate numbers are publicly checkable at NIST. An unverifiable claim is a disqualifier, not a negotiation point.

出货是原厂品牌标还是可贴牌（白标/OEM）？如为原厂标，序列号能否在原厂官网查询到有效保修？

Shipped with the original vendor label, or white-label/OEM relabelled? If vendor-labelled, can the serial numbers be looked up for valid warranty on the vendor's own site?

A vendor label the vendor's warranty database does not recognise means the label is fake or the warranty was already consumed.

支持哪些LBA格式（512、4096）？是否支持带元数据的格式（如4096+8、4096+64）用于端到端数据保护？出厂默认是哪一种？是否可用nvme format重新格式化？

Which LBA formats are supported (512, 4096)? Are metadata formats (e.g. 4096+8, 4096+64) supported for end-to-end data protection? Which is the factory default? Can it be reformatted with `nvme format`?

The HDD side of the report catches 520-byte NetApp pulls; the NVMe side has the same trap and no field for it. An OEM-formatted drive with unexpected metadata will not initialise in a standard array.

固件如何升级？是否可用标准nvme-cli带内升级？固件镜像是否有签名校验（会不会拒绝第三方固件）？贵司是否长期提供固件更新？出货固件版本号是多少，是否为最新？

How is firmware updated? Can standard nvme-cli do an in-band update? Are firmware images signature-verified (i.e. will it reject third-party firmware)? Will you supply firmware updates over the product's life? What firmware revision ships, and is it the latest?

An enterprise fleet needs a firmware update path for the bug you have not hit yet. A drive with no update route is a consumer drive in a server case.

温度节流起始温度(WCTEMP)和临界温度(CCTEMP)分别是多少？在35摄氏度环境温度、机箱标准风量下，持续写入时的性能相比25度下降多少百分比？是否需要额外散热片？

At what composite temperature does it start throttling (WCTEMP) and at what temperature does it shut down (CCTEMP)? At 35C ambient with standard chassis airflow, what percentage of sustained-write performance is retained versus 25C? Is an additional heatsink required?

Pairs with the report's existing power field. A Gen5 drive that meets its benchmark at 22C on a bench and throttles 40% in a warm aisle is a different product from the one you paid for.

能否书面保证本订单全部数量使用同一批次闪存、同一主控型号和同一固件版本？如中途更换供料或主控，是否提前书面通知并允许我方拒收？请提供PCN变更通知承诺。

Will you guarantee in writing that the entire order uses the same NAND source, the same controller model and the same firmware revision? If you change component sourcing or controller mid-order, will you give advance written notice and allow us to reject? Provide a PCN (product change notification) commitment.

The report's best questions establish what is in ONE drive. Nothing binds the seller to ship that same drive for the rest of the order — and silent BOM swaps between shipments are routine among module makers.

能否在下单前提供3-5片样品供我方做至少72小时稳态压力测试？如样品测试不合格，样品费用如何处理？到货后我方按什么标准抽检、抽检不合格能否整批退货？

Will you send 3-5 samples before the PO for at least 72 hours of steady-state stress testing on our side? If samples fail, how is the sample cost handled? On delivery, what sampling standard applies, and can we reject the whole lot on a failed sample?

Converts every technical question above from a claim into an enforceable term. A seller who refuses pre-PO samples on a volume order is telling you something.
