- Reviewed in the United States on April 21, 2021Capacity: 1TBVerified PurchaseBought the P31 Gold to take over as primary drive from my Intel 600p 512GB SSD, located in the upper M2 slot above the GPU and under the CPU radiator/fan (a more confined space).
Physical installation: Installed easily in the lower M2 slot under the GPU (GTX 1070).
Cloning: The standard Macrium cloning software from the sk Hynix web site (SKHSSD.exe) did not work due to VSS errors I could not resolve (their manual just said to look on the internet for solutions, none of which worked). Instead, I went to Macrium's web site and downloaded Reflect, which worked. After updating the BIOS settings, the new drive booted fine.
Tests using Crystal Disk:
- Temps: Both SSDs peaked at 66C, while the P31 Gold idles 8C to 10C higher (very little difference when using the upper M2 slot). If I manually increased the GPU fans to 80% or so, the SK Hynix's temp dropped significantly as the GPU pulled more hot air away from the drive. I added an internal fan to blow across the drive - the SK Hynix temps improved and are just 4C-5C above the Intel's.
- Read/Write speeds: the P31's throughput was 2x to 5x faster in most cases, which means any R/W operation finishes much faster, for less time at the higher temps. The Intel came close in random writes.
Bottom line: Very good value, fast read/write and reasonable temps with the proper air flow, but not very good online customer support yet (however, once installed, it's really not needed). I may try a heat sink in the future and remove the internal fan to compare the difference.
1 Year later - very satisfied. Removed the internal fan that was blowing directly on the SSD, and temps remained well within normal ranges when compared to other similar capacity SDDs; so I decided against adding a heatsink. My only advice for new SSD buyers is to get more than you think you need; I had a faulty app that caused unnecessary SSD life loss due to excessive writes before I was able to isolate the problem.
- Reviewed in the United States on March 1, 2025Capacity: 2TBVerified PurchaseWorks great. Blazing fast. Just remember trying to clone this bad boy means you gotta do a bitlocker recovery via Microsoft website.
- Reviewed in the United States on January 19, 2025Capacity: 2TBVerified PurchaseGood drive, consistent high speeds. I use as an external storage drive for my zcam s6 camera. Records the highest resolutions along with beefiest codecs no problems. I get around 900/900 read/write which is due in part to the limitations of my nvme enclosure.
Overall, it meets my expectations and performs great.

✅ ▌𝐻𝒴𝒟𝑅𝒜 ▌🥇Reviewed in Italy on March 31, 2025
5.0 out of 5 stars Un ottimo SSD con cache DRam
Capacity: 2TBVerified PurchaseAcquistato questo SK hynix Gold P31 da 2TB per aggiornare il mio sistema e devo dire che le prestazioni sono esattamente quelle che mi aspettavo, se non superiori per un SSD di questa fascia. Analizziamo un po' più a fondo le sue caratteristiche tecniche.
Prestazioni al Banco di Prova: Nei miei test con CrystalDiskMark, ho rilevato velocità di lettura sequenziale che si attestano sui 3600 MB/s e velocità di scrittura sequenziale intorno ai 3350 MB/s , in linea con le specifiche dichiarate dal produttore (3500 MB/s in lettura e 3200 MB/s in scrittura) . Anche le performance in lettura e scrittura casuale (4K) sono notevoli, con circa 54 MB/s in lettura e 194 MB/s in scrittura con una singola coda e thread, che salgono a circa 1964 MB/s in lettura e 3237 MB/s in scrittura con code e thread multipli . Questo si traduce in un'ottima reattività del sistema e tempi di caricamento rapidi per applicazioni e giochi.
Componentistica Interna: Un aspetto che mi ha convinto è che SK hynix produce internamente sia la memoria NAND che il controller. Questo modello utilizza NAND 3D TLC a 128 layer prodotta da SK hynix e un controller proprietario ACNT038 (o Cepheus) . La presenza di 2GB di cache DRAM LPDDR4 a 4266MHz contribuisce significativamente alle prestazioni, specialmente nelle operazioni di lettura e scrittura casuali.
Endurance e Affidabilità: L'SK hynix Gold P31 2TB vanta un valore di TBW (Terabytes Written) di ben 1200 TB , il che indica un'elevata durabilità e una lunga vita operativa, anche con un utilizzo intenso. La garanzia di 5 anni fornita da SK hynix è un ulteriore segno di fiducia nella qualità del prodotto.
Efficienza Energetica e Temperature: Ho notato che questo SSD ha un consumo energetico contenuto e non scalda eccessivamente, un aspetto particolarmente apprezzabile se utilizzato in un laptop o in sistemi con spazio limitato per la dissipazione del calore. Nei miei test, le temperature non hanno mai raggiunto livelli preoccupanti.
Confronto con la Concorrenza: Rispetto ad altri SSD PCIe Gen3 da 2TB, l'SK hynix Gold P31 si posiziona molto bene in termini di rapporto prestazioni/prezzo. Sebbene alcuni SSD Gen4 possano offrire velocità sequenziali superiori, per la maggior parte degli utilizzi quotidiani e anche per il gaming, le prestazioni di questo P31 sono più che adeguate e spesso superiori ad altri Gen3.
Conclusioni: Se cercate un SSD NVMe Gen3 da 2TB con prestazioni solide, componentistica di qualità prodotta da un'azienda con una lunga storia nel settore della memoria, un'ottima endurance e un prezzo competitivo , l'SK hynix Gold P31 è sicuramente da prendere in considerazione. Un prodotto affidabile che ha dato nuova vita al mio sistema. Consigliatissimo!

5.0 out of 5 stars Most power efficient ssd on the planet, gen 4's and 5's dont compete.
Capacity: 2TBVerified PurchaseBest value, best real world performance, best power efficiency, all in a gen 3 drive. There is no need for gen 4 or 5 drives, this drive still leads in power efficiency and real world performance at a lower price.
