ARCANITE 512GB USB 3.1 Flash Drive - Optimal Read speeds up to 400 MB/s, Write speeds up to 200 MB/s (AK58512G)

Best flash drives I've ever had! I bought 2 of these several years ago, and to this day I have never had a single problem. The cap on it is amazing, and it fits on the end so you won't lose it. File transfers are fast, compatible with every device I've ever tried, and they are easy to carry around. They're a bit pricey perhaps, but 100% worth it based on the quality and durability. I don't really leave reviews, however this product deserves it.

It's one of the best products with proposed a r/w speed. While many other seller companies specify and a max theoretical speed, this one indicates the stated speed that's important for write activity first of all. Obviously, it's about seq r/w speed and these speed values are stable (not goes down after several GBs copied like others). Also, this flash driver has a small part ~230-250MB in the beginning, so if you formatted and made 1 volume you will and a fall of speed at first ~230-250MB. Anyway, among other 3.1 flash drives, this one is highly recommended

VERY VERY GOOD RESULTS! I RECOMEND!

I purchased three different flash drives and have a good comparison between them. The Arcanite drive is the best value for the storage space and form factor, but comes up short on speeds. Pros: Speed- Yes this is a fast drive...for reads. I was able to hit 250mbps easily and up to 300mbps at times. More about write speeds later. Form Factor- I like the sturdy feeling casing and design of this drive. It's nice that the cap snaps back onto the case while in use Storage- Great value for the amount of storage space you get. Cons: Speed- Write speeds would start out decent, around 150-200mbps for around 10 seconds. After that the drive would slow quickly to 50-70mbps for the duration of the write. I believe they have some form of high speed caching for the first few hundred Mb and then it can only write at the standard module speed. Formatting- Came formatted in FAT32, which is outdated and limits files to 4Gb, be prepared to reformat into a better filesystem. Overall this 128Gb drive was a good value and will suit someone who needs quick reads and higher than average writes. If you plan do to a lot of single writes and reads, like transferring some files for work or school, then you may be better off spending more money on a Sandisk Extreme go, which has writes almost three time as a fast, even though the reads are about 30% slower. Also, don't buy any drive with less than 128Gb as files are so large nowadays. *My review based on 128Gb model, which may have slightly slower reads than the large devices.

I've been burned several times trying to find an actual real 1tb thumb drive. This one is an actual 1tb drive. I've learned that the first thing you need to do is to try to fill the thing up at least 1/2 way. If you can do this and read back the data then you're golden.

PS5 REVIEW!! We ordered this to use as extended storage for the PS5 since the m.2 port on the PS5 doesn’t work yet in the firmware. We had failed with a few other drives because the PS5 requires the drive used for external to be a min speed and many drives just did not cut it. This drive was easy to setup for this purpose and so far has worked great copying many of my larger games over to the drive successfully. For now, all I can say is that it works and the PS5 seems to accept it. The next test over the coming weeks will be to see how the games run on it and if there are any performance issues. We will update this review with those results once we have them.

Update: I had ordered 3. I was using one on a mission ciritical backup. On second day it failed; taking down important backup on it. Windows suddenly said that the thumb drive needs formatting before use! (read: toasted). When I proceed by formatting (do I have any chance?); it then said "write protected"! (it doesn't have write protect switch)! So 1 out of 3 hits the garbage can. I'll be testing remaining 2 before I ever use them on an important task again. Impressive speed - but not so impressive reliability so far. ------------------------------------ Not only at this price-point, but even in much more expensive models you don't find such high speed write performance. Even the big brands don't have it. Order it while it's still available.

I bought this ARCANITE 512GB USB 3.1 Flash Drive because it had reasonably good reviews, and the price was reasonable (compared to some of the competitors). I used a USB 3.0 slot on my computer to do the minor testing. I checked the size and found that it really is a 512GB unit. It really can hold that much data. Then I did a couple of tests involving speed, with considerations for file size. In the first test, I copied 5 movie files from my main drive to the empty ARCANITE. The overall size of the 5 files was 9 GB. The copy speeds ran steadily in the range of 90 MB/s to 140 MB/s with occasional spikes in either direction. Then I tried small files. It was hundreds of small MS Word and MS Excel and even pdf files, that all together added up to just about 1 GB. Once again, I copied the files from my main drive to the empty ARCANITE. The copy speed ran consistently in the range of 5 to 20 MB/s with very few spikes either way. I found the 5 to 20 MB/s rather disappointing, but overall, I'm happy with the ARCANITE performance with the larger files. Lastly, it's important to remember that, I was using a USB 3.0 slot. The ARCANITE is advertised as a USB 3.1 drive, so maybe it would have performed faster in a USB 3.1 slot.

Je fais mes sauvegardes sociétés et je ne prends que des clés USB de marques reconnues. J'ai pris le risque de cet achat pensant le retourner. Capacité conforme et rapidité d'écriture et lecture digne d'une grande marque.

I purchased the 128GB version. Pros: It performs fast with both read & writes. I measured an average of 350 MB/s read over various size files. The write speed performs best with larger file sizes about 350-370 MB/s, with many files 1-5MB sizes the write speed was high for the first couple hundred MB then slowed to as low as 55MB/s. I never saw a speed less than 55MB/s to/from this drive. Well worth it. I will buy again if I need another one. Cons: Separate cap easy to misplace, but it does clip on with a positive click though. So not really bad. Many of the bulk USB keys say fast speed but only imply the read speed; that almost always means the write speed sucks.

Der USB-Stick ist schön handlich und sieht neutral aus. Es gibt ein kleines Loch, um ein Band durchzuziehen und ihn so z.B. am Schlüsselbund o.ä. zu befestigen. Laut Hersteller soll er bis zu 400 MB/s beim Lesen und 100 MB/s beim Schreiben erreichen. Im kurzen Benchmark-Test (CrystalDiskMark) erreicht der Stick bei mir knapp 431 MB/s beim Lesen und extrem starke 225 MB/s beim Schreiben - er übertrifft die Angaben hier also massiv! Schreibt man den kompletten Stick am Stück voll (Dauerbelastung; getestet mit H2testw), ist der schnelle Zwischenspeicher irgendwann voll. Aber selbst dann pendelt sich der Stick bei soliden 72,6 MB/s beim Schreiben und 359 MB/s beim Lesen ein. Zudem hat der Test bestätigt: Der Speicher ist echt und fehlerfrei. Für große Dateien wie Videos oder Dokumente ist er damit perfekt geeignet. Ein richtig starker Stick für einen fairen Preis - klare Kaufempfehlung.

Dopo più di un anno di utilizzo posso dire che si tratta di una chiavetta USB ben fatta, equilibrata come prezzo/prestazioni. Molto capiente (1TB) senza sacrificare le prestazioni.

Dopo che la mia pendrive con la quale lavoravo da anni da un giorno all'altro mi ha lasciato a piedi a causa di una cattiva rimozione, ho deciso di acquistarne una nuova, scegliendo ovviamente qualcosa che fosse di dimensione maggiore dato che ormai avere a che fare con file superiori al gigabyte è una cosa ormai ordinaria. Dopo aver controllato i soliti marchi, mi è capitato casualmente l'occhio su questa ARCANITE, che onestamente non avevo mai sentito prima. Ero un po' scettico poichè nonostante le buone recensioni, dalle foto mi sembrava un oggetto piuttosto grande, invece una volta ricevuta mi sono dovuto ricredere del tutto. Il prodotto è ben fatto, di una plastica leggermente rugged, ed è molto compatta e leggera, come si può vedere dalle foto. Il cappuccio ha un buono scatto di apertura/chiusura e non da affatto l'idea di un qualcosa che si possa allentare con l'uso, anche se ovviamente sarà il tempo a dirlo. Ottima cosa il poterlo agganciare al retro della penna per evitare di lasciarlo in giro e rischiare quindi di perderlo. Altra cosa che mi ha convinto è che il prodotto, come si vede dalla foto del retro confezione, è progettato in Giappone ed è costruito in Taiwan, quindi se non altro una novità rispetto al solito "made in china", sperando che ciò si traduca in una scelta più attenta dei chip e soprattutto della loro durata nel tempo. Dopo queste breve considerazioni estetiche e funzionali passiamo alla parte forse più interessante della questione, le prestazioni. Si chiaro fin da subito che personalmente non credo mai a quello che dichiarano i produttori sulle confezioni (nel nostro caso Velocità di lettura fino a 400 MB/s; velocità di scrittura fino a 100 MB/s) dato che questi dati sono valori massimi teorici o comunque in condizioni ideali del produttore. Si sa che i dati reali sono diversi, solitamente peggiori...ma di quanto? Nel mio caso, la velocità di scrittura media in condizioni di benchmark è stata intorno agli 83 Mb/s, un ottimo valore sicuramente, ma anche qui, non realistico. Trasferendo un file unico di 8GB da SSD a pendrive su porta usb3.0 ovviamente, la velocità di trasferimento è stata altalenante tra i 45 ed i 60 Mb/s, buoni valori ma come si vede lontani dai 100 Mb/s dichiarati dal produttore. Tale dato è oltretutto destinato ad essere ancora peggiore nel caso si trasferiscano tanti file piccoli piuttosto che uno o due grandi. Per quanto riguarda la velocità di lettura, eccellente nel benchmark con 255 Mb/s di media, ma trasferendo invece da penna ad hard-disk, è stata quasi costante a circa 125 Mb/s, ottimo valore ma lontanissimo dai 400 Mb/s dichiarati. Nel complesso il prodotto mi sembra valido, specialmente se riuscite ad acquistarlo ad un buon prezzo (22-25 euro)e per i miei utilizzi è sufficiente, seppur i valori siano diversi da quelli dichiarati (ma questa cosa me l'aspettavo e tutto sommato sono valori discreti). Concludo dicendo che il prodotto non presenta LED di lettura/scrittura, peccato perchè sarebbe stata una cosa gradita e vedo che questa caratteristica è stata richiesta nelle domande relative. In conclusione sarà importante valutare due cose nel tempo. La prima è vedere come si manterranno le prestazioni man mano che i cicli di lettura/scrittura vanno ad usurare il chip, cosa inevitabile. La seconda è che la penna non mi lasci a piedi all'improvviso come ha fatto l'altra. Servizio amazon perfetto come sempre.
