Extremely pleased with them - heartily recommended!
I've bought 4 of these 16TB Exos disks and have checked each disk individually. The disks have recertified labels on them, but have 0 errors and 0 power on hours with 1.3TB host reads.They're remarkably quiet despite what people might tend to say about Exos disk or bigger disks in general. They're performing as expected (well!) in my UGreen NAS.To be clear, my disks were all sold by Amazon EU and came from the Northern France/Belgium area, only taking an extra day to get here over a normal Prime delivery.Extremely pleased with them - heartily recommended!

Seagate Exos X18: Un gigante buono per il tuo NAS da 16TB Ricondizionato
Alla ricerca di un disco rigido per il mio NAS che fosse affidabile, capiente e performante, mi sono imbattuto nel Seagate Exos X18 Ricondizionato. Un vero e proprio gigante da 16TB che prometteva di archiviare i miei dati più preziosi con la sicurezza di un bunker e la velocità di un fulmine. Ma sarà davvero all'altezza delle sue promesse?Descrizione del Prodotto:L'Exos X18 si presenta come un hard disk da 3,5 pollici con un'interfaccia SATA 6Gb/s. La sua capacità di 16TB è a dir poco mostruosa (formattata 14,5TB), perfetta per archiviare foto, video, musica e qualsiasi altro tipo di file. La tecnologia CMR (Conventional Magnetic Recording) garantisce affidabilità e stabilità nel tempo, mentre la velocità di rotazione di 7200 giri/min assicura prestazioni eccellenti.Unboxing:L'hard disk è arrivato ben imballato in una scatola di cartone robusta e protettiva. All'interno, oltre al disco stesso, ho trovato un manuale di istruzioni e alcuni adesivi Seagate. Niente di più, niente di meno.Esperienza d'Uso:L'installazione dell'Exos X18 nel mio NAS è stata un gioco da ragazzi. L'ho semplicemente inserito nello slot dedicato e avvitato le viti. Il sistema lo ha riconosciuto immediatamente e non ho dovuto installare alcun driver.Prestazioni:Le prestazioni dell'Exos X18 sono davvero notevoli. La velocità di lettura e scrittura è eccellente, intorno a 250mb/s, sia per file di grandi dimensioni che per piccoli file. Non ho mai avuto problemi di lag o di rallentamenti, anche durante l'accesso simultaneo da più dispositivi.Lo testato, essendo ricondizionato, riempiendolo fino al riempimento del disco, cosi da verificare la bontà nella scrittura e devo dire che è stato perfetto.Lo SMART me lo da come nuovo, non so se hanno azzerato tutto oppure e completamente nuovo, ma io lo preso ricondizionato.Pro:Capacità di archiviazione mostruosa (16TB)Tecnologia CMR per affidabilità e stabilitàVelocità di rotazione di 7200 giri/min per prestazioni eccellentiInterfaccia SATA 6Gb/s per trasferimenti dati rapidiBasso consumo energeticoSilenziosoContro:Prezzo un po' elevatoNon adatto per l'uso in sistemi desktop o notebookCritiche e Limitazioni:L'unico vero neo dell'Exos X18 è il prezzo, che non è proprio per tutte le tasche. Tuttavia, la sua capacità di archiviazione e le sue prestazioni eccellenti lo rendono un investimento worthwhile per chi ha bisogno di un disco rigido affidabile e performante per il proprio NAS.Conclusioni:Se siete alla ricerca di un hard disk per il vostro NAS che sia capiente, affidabile e performante, il Seagate Exos X18 è la scelta ideale, specialmente se è ricondizionato risparmiate sui prezzo di molto. Non vi deluderà!Spero che questa recensione vi abbia aiutato a scegliere. Se così fosse, vi sarei grato se cliccaste sul tasto "utile"Grazie,Andrea

Good value for the money.
I ordered 4pcs Seagate Exos X18 Enterprise HDD, 16 TB HDD.All disks was working upon delivery, I ran SMART test and all showed good results. The disks showed zero power on hours. I noticed that one of the controlboards was different from the others, I assume it might have been replaced. Eitherway they all worked and are now mounted inside my NAS.

Seagate Exos X18 Enterprise 16TB HDD – High Capacity, Reliable Performance for Hyperscale Workloads
Quick Specs Snapshot• Capacity: 16 TB per drive (largest in Seagate’s Exos line)• Interface: SATA 6 Gb/s, 3.5‑inch form factor• Rotation Speed: 7200 rpm (CMR – Conventional Magnetic Recording)• Sector Size: 512e (logical 512‑byte sectors on a 4K physical sector)• Cache/Buffer: 256 MB DDR3 SDRAM• Power Consumption: Idle ≈2.5 W, Peak ≈10–12 W• Operating Temperature: 0 °C to 55 °C (recommended ≤40 °C ambient)• Noise Level: ~35 dB(A) at 1 m• Warranty: 5‑year limited, MTBF ≈2 million hoursInstallation & CompatibilityThe Exos X18 is a standard 3.5‑inch SATA drive. It plugs into any server or NAS chassis that supports 3.5‑inch drives and SATA 6 Gb/s data lines. The power connector is the usual 4‑pin Molex (or SATA power) used on most enterprise enclosures. Hot‑swap capability depends on your enclosure; many modern racks support hot‑plugging for SATA drives.Because it uses 512e sector size, the drive is fully compatible with all current Windows Server, Linux, and VMware environments that support 4K sectors. Older consumer operating systems that only recognize 512‑byte sectors may require a BIOS/OS update or a separate 512e‑to‑512‑bypass driver.Performance (Sequential & Random)Sequential Read: Up to ~240 MB/s under optimal conditions (full 7200 rpm, no other drives competing for bandwidth).Sequential Write: Slightly lower (~220 MB/s), due to the overhead of error correction and data integrity checks typical of enterprise drives.Random I/O (4K) – Typical workloads in a virtualized or database environment:• Reads: ~80–100 k IOPS (depending on queue depth, 16‑bit vs. 32‑bit addressing)• Writes: ~70–90 k IOPS (write amplification and ECC overhead slightly reduce throughput)The CMR technology ensures that random access performance remains stable even under heavy mixed workloads, unlike SMR drives which can suffer from write penalties.Thermal & Power ProfileAt idle the drive draws about 2.5 W; during sustained sequential operations it peaks around 10–12 W. This is typical for a 7200‑rpm enterprise HDD and translates to roughly 1.3 W per TB of capacity. The built‑in heat sink, combined with adequate airflow from the enclosure fan, keeps operating temperatures well below the 55 °C limit even in dense racks.Noise is moderate; at 1 m distance the drive registers ~35 dB(A), which is acceptable for most data‑center and high‑density NAS environments.Reliability & EnduranceSeagate advertises an MTBF of approximately 2 million hours (≈228 years) and a TBW rating of 120 TB for the 16 TB model. In practice, this means the drive should comfortably support ~7–8 years of continuous operation at typical data‑center workloads before reaching its endurance limit.The drive supports SMART monitoring and predictive failure analysis; Seagate’s Enterprise Drive Software can alert administrators to impending failures long before data loss occurs.Pros• Massive 16 TB capacity – the largest single‑drive option in the Exos family, ideal for hyperscale storage pools.• CMR technology delivers stable random I/O performance, making it suitable for databases, virtualization, and mixed workloads.• 512e sector size aligns with modern data‑center standards, ensuring compatibility with most server OSes and hypervisors.• Energy‑efficient – low idle power and dynamic scaling reduce operating costs in large deployments.• 5‑year warranty and high MTBF provide confidence for mission‑critical environments.Cons• Sequential write speed is modest compared to newer 10 k or SAS drives; may be a bottleneck for write‑heavy backup workloads.• Noise level, while moderate, can add up in very dense racks if many drives run simultaneously.• No built‑in hardware encryption – users must rely on software or host‑based solutions for data protection.• 512e sector size requires OS support; older consumer systems may need updates or drivers.VerdictThe Seagate Exos X18 16 TB is a solid, high‑capacity workhorse for enterprises that prioritize storage density and reliability over raw speed. Its CMR design gives it an edge in random access scenarios where SMR drives would falter, while its energy efficiency keeps power bills reasonable. For hyperscale data centers, NAS arrays, or virtualized environments that need the largest single drive available, this model delivers on performance, endurance, and value.Overall rating: 4.5 out of 5 stars.
