Micron 7450 PRO U.3 NVMe SSDs with HPE part numbers, 960 GB and 3.84 TB, new in volume

Arch Point Recovery is offering two seller-described new Micron 7450 PRO SSD SKUs in volume: 960 GB at $330 per drive and 3.84 TB at $650 per drive. The offer specifies 50 drives per carton, 1,000+ of each SKU and a 90-day warranty. Exact stock, carrier contents and written warranty terms are confirmed with the order. Carton and label photographs are pending; the listing uses a clearly marked placeholder.

View the SSD lot and current availability. This guide explains the technology, capacity economics and checks needed before a fleet purchase.

These full identifiers need confirmation against physical labels. Public HPE documentation reviewed for this guide did not establish an exact cross-reference for either supplied HPE number. A capacity match to another HPE option kit is insufficient to promise compatibility.

What the Micron 7450 PRO is

The 7450 family is enterprise PCIe Gen4 NVMe storage using TLC NAND, with power-loss protection and firmware features intended for datacenter service. PRO is the read-intensive endurance class. Micron’s original 7450 product brief, 2022, hosted by its distributor lists PRO at 1 drive write per day, MAX at 3 DWPD, and U.3 sequential reads up to 6.8 GB/s: approximately the 7 GB/s class, not a measured speed for this lot. Smaller capacities have lower write specifications.

The family offers TCG Opal security configurations, but Opal capability on these exact OEM SKUs is unverified. Record the complete ordering suffix and security state rather than assuming every 7450 has the same encryption feature set. The current Micron family page now emphasizes M.2 and E1.S. The later technical specification supplied with this lot explicitly removed U.3 tables; it is useful for family context, not historical U.3 capacity-specific performance.

HPE part numbers, firmware and carriers

Treat these as an OEM qualification project. HPE-branded drives may use HPE firmware and qualification rules; the label, NVMe Identify data and firmware revision must establish what is actually supplied. Do not cross-flash generic Micron firmware merely because the controller family matches. Micron’s firmware support page is a reference for its own releases, not an authorization to overwrite an OEM image. It lists E2MU300 for generic 7450 drives, released October 2025; request the appropriate HPE-supported version and confirmation of applicable firmware advisories for this lot.

HPE’s SSD QuickSpecs describes a Multi Vendor program that groups qualified vendor devices under capacity-based option SKUs with published minimum performance and power specifications. Its NVMe tables include Static Multi Vendor and Static V2 Multi Vendor offerings. Buyers should order and qualify against the exact option, carrier and firmware combination; the program name does not guarantee a particular Micron model or make a loose drive equivalent to a complete HPE kit.

The drive body’s 7 mm or 15 mm height is separate from the carrier type. HPE Basic Carrier (BC), Smart Carrier (SC) and Smart Carrier NVMe (SCN) are not interchangeable promises. A 15 mm body cannot fit a bay limited to 7 mm; a thinner body still needs correct mounting, connector alignment and airflow.

There is no verified server-by-server acceptance matrix for the two supplied part numbers yet. HPE Smart Array branding alone also does not establish NVMe support: check the exact controller, tri-mode cabling/backplane or direct PCIe path and the operating-system driver stack.

U.3 vs U.2 vs E1.S

U.2 and U.3 describe 2.5-inch enterprise drive interfaces; U.3 enables compatible tri-mode infrastructure. Micron’s original product brief describes the 7450 U.3 models as backward-compatible with U.2 hosts. That still requires an NVMe-capable host path: a SATA-only bay will not become NVMe through a physical carrier change.

E1.S is a different EDSFF shape and connector ecosystem. An E1.S 7450 benchmark or marketing photograph does not identify the U.3 hardware offered here. For adapters or non-HPE servers, qualify PCIe lanes, power, hot-plug behavior, cooling, boot support and fault reporting with a sample first.

RI vs MU: where 1 DWPD fits

Read-intensive (RI) and mixed-use (MU) describe endurance classes, not a ban on writes. At 1 DWPD, the arithmetic write budget is about 960 GB/day for a 960 GB drive or 3.84 TB/day for a 3.84 TB drive, under the manufacturer’s endurance conditions. Over five years, that is roughly 1,752 TB or 7,008 TB of host writes as a planning calculation; use the exact SKU’s rated TBW for acceptance.

Measure daily host writes, peaks, free-space reserve and rebuild traffic. Heavy database compaction, write-back caching or repeated checkpoint replacement can justify a higher-endurance MU drive. Family endurance specifications do not extend this offer’s 90-day warranty into a five-year seller warranty.

Capacity planning at $330 and $650

All capacity arithmetic below uses decimal TB. Prices exclude freight, taxes and any separately required carriers, installation or support.

The 3.84 TB SKU supplies four times the raw capacity for about 1.97 times the drive price, reducing bay count for a given capacity target. One thousand of each would total 4.8 PB raw, 40 cartons and $980,000 at the stated asks; this is order arithmetic, not a reservation of stock.

For example, 12 × 3.84 TB gives 46.08 TB raw for $7,800. Six mirrored pairs provide 23.04 TB before formatting and operating reserve, bringing drive-only cost to about $338.54 per usable TB. A three-replica object store uses roughly three raw TB per logical TB before further overhead. Price the protection scheme and spare pool, not just the headline raw $/TB.

Published tests, coverage and operator reports

These sources establish family context and test ideas. Different capacities, firmware, hosts and test recipes prevent them from certifying this inventory’s performance or reliability. Dates below identify publication dates where available; sources were checked September 22, 2026.

• StorageReview, March 1, 2022 covered the launch, including U.3 7 mm and 15 mm variants. This was an announcement based on vendor specifications, not its own 7450 test.
• ServeTheHome, March 2, 2022 likewise reported the launch and noted the large capacity-dependent variation in write speeds. Its 7400 hands-on reviews concern a different generation.
• Boston Labs, August 2, 2022 tested U.3 drives in a Supermicro system, including four drives with Intel VROC RAID 0. It reported 16.7 GB/s read throughput for that array; this is integrator lab work, not a per-drive claim or a redundancy configuration.
• Micron’s RocksDB comparison, July 1, 2023 used a 1 TB database and varied concurrency. It reported close results between the 7450 and Samsung PM9A3, with advantages changing by workload/thread count. This is manufacturer lab work.
• Micron’s current family documentation, checked September 22, 2026 describes OCP Datacenter NVMe SSD 2.0 support, latency monitoring and standardized administration. Confirm those functions in the actual OEM firmware rather than treating this lot as universally OCP-certified.
• A ServeTheHome forum thread, February 27, 2025 records one operator asking for E2MU206 firmware and reporting difficulty obtaining it. This is an individual support experience, not evidence of a product-wide failure rate; establish an OEM-supported update route before buying.

Workloads worth qualifying

Databases: read-heavy indexes, query serving and moderate-write transactional systems are candidates. Measure tail latency during compaction, backups and rebuilds, not only empty-drive sequential reads.

Object storage: capacity nodes and read-heavy object pools can use the 3.84 TB SKU efficiently. Include replication or erasure coding, metadata traffic, failure domains and recovery writes in sizing.

AI data staging: local datasets, model files and reusable inference assets are plausible uses alongside GPU compute infrastructure. These drives do not expand GPU VRAM. Check sustained ingest and checkpoint writes against the endurance budget.

VM and host boot: the 960 GB SKU may suit boot mirrors or modest read-heavy VM pools where a qualified U.3 path exists. Boot storms, snapshots and swap can change the workload substantially; an M.2-only boot module cannot accept this U.3 lot.

How to qualify new-in-box OEM drives

1. Request real carton and label photographs, serial ranges, seal condition and a count by SKU. Resolve the exact Micron suffixes and HPE identifiers before a purchase order.
2. Agree sampled SMART/NVMe logs before and after acceptance testing. Request power-on hours = 0 as the new-stock target, together with power cycles, data units read/written, percentage used, media errors, critical warnings and unsafe shutdown counts. Factory validation may leave small counters; any exception needs a written explanation. Zero hours alone does not prove authenticity or unused condition.
3. Capture NVMe Identify model, serial, firmware, namespace capacity and sector format. Verify security capabilities and that no ownership lock blocks deployment.
4. Test a sample in the intended HPE server, with the exact carrier, controller/backplane and BIOS/iLO/driver versions. Check enumeration, boot, health reporting, hot-plug and rebuild behavior as applicable.
5. Run a representative sustained workload under production-like airflow. Record temperature, throttling and error logs; agree whether testing may write to or open sampled units.
6. Put the 90-day warranty in writing: start date, DOA window, remedies, exclusions, return freight and responsible warrantor. HPE or Micron warranty transfer is not established by an OEM part number.

FAQ

Are these new drives, and are real photos available?

The offer describes new stock boxed 50 per carton. Real carton and label photographs are pending; the listing image is a branded placeholder. Confirm condition with labels, serials and agreed sample tests.

What are the prices and minimum quantities?

The asks are $330 per 960 GB drive and $650 per 3.84 TB drive for volume orders. The seller reports 1,000+ per SKU. Ask about carton orders, samples, mixed pallets and exact available quantities; 50/carton is packaging, not a confirmed minimum order.

Do the HPE part numbers guarantee ProLiant or Alletra compatibility?

No. The supplied P65871-001 and P60505-001 identifiers require label confirmation and an exact platform/option cross-reference. Carrier, cage, controller and firmware must all qualify.

Can the 7 mm drive replace a 15 mm drive?

Only after checking the carrier’s mounting and connector alignment, cooling and platform qualification. The thinner body is not by itself proof of an approved replacement.

Can a U.3 7450 work in a U.2 system?

Micron describes the U.3 family as backward-compatible with U.2 hosts. The actual host must support NVMe and the drive’s power, physical mounting and firmware requirements. SATA-only bays are insufficient.

Is 1 DWPD enough for a database?

It can be, if measured host writes including maintenance and recovery stay within the exact drive’s endurance rating. A write-heavy database may need MU endurance or more drives to spread writes.

Are these all TCG Opal self-encrypting drives?

That is not verified. The 7450 family includes security variants; confirm the complete label suffix and Identify/security data for each SKU rather than assuming identical capabilities.

Does the 90-day warranty include HPE support?

No HPE support entitlement or manufacturer warranty transfer is established here. Request the seller’s written 90-day terms and any separately documented OEM coverage.
