Kingston Digital HyperX 3.0 DataTraveler (DTHX30/64GB)

It does what it was designed to do - run screaming fast in a USB-3 port. I long/full formatted the entire 64GB unit as NTFS in 8 minutes using an EVGA PC motherboard SuperSpeed USB-3 port (completed 8GB/min or 133MB/sec , Bytes, not bits) - that's like writing about a full CD worth of data in 5 seconds! That is writing (not faster reading) at about 22% the maximum theoretica; USB-3 bus speed. In comparison, it takes a regular 4GB USB-2 Kingston G3 ($5) stick 15 minutes for the same operation (32x slower). If you can afford a new PC or laptop with USB-3 ports, you must also have one of these to make good use of that port. It is worth noting that after the massive 64GB high-speed format, the stick was very warm and surprised me when I grabbed it to extract it from the port - guess that's what all that blue cooling metal wrap is for! The 133MB/sec format speed is right at the advertised write speed, so I'm not sure about some reviewers' complaints of mis-advertising, even though I recognize "real data writing" could be slower for multiple files or many small files. At some point, it becomes difficult to go any faster because you cannot adequately dissipate the heat. Recommended if needed, and if affordable - esp. for frequent and/or very large file transfers. Kingston makes great memory products of many types to suit many use and price-point needs. Hyper-X 3.0 is their new flagship, replacing their previous Hyper-X USB-2 unit (which I also own). As is often true, Amazon rocks again with the best price - thanks!

I bought one of these drives 8 months ago, and I have used it daily since then. It lives up to its stated data rates (130MB/s write, 220MB/s read on USB 3.0). 4-hour-plus full backups with my USB 2.0 device now take 45 minutes. Size is small, for a 128GB device, though it's larger than all my smaller-capacity flash drives. It works fine on USB 2.0 as well, though at much lower data rates. All in all, I don't have anything bad to say about this device.Then, I lost it. So, I'm buying another to replace it. Can't live without it.

This is undeniably the fastest USB Flash drive you can buy in 2013.My measured speeds are 277735 KB/s Sequential Read 193984 KB/s Sequential Write on NTFS with a 4k block size.4KB random IOPS run at 2154 Read and 353 Write,The Flash drives speeds at USB 3.0 are the best I have ever seen to date, and usage is rock solid.The only possible negative I could note is that the stick is rather thick and could be trouble in certain ports, however it IS offset to one side, so this allows it to work around some location problems.Very Happy with the performance so far.

Most of the other reviews are spot on. Other than the couple of defective units, slow speeds are typically using it in a manner that cannot achieve the maximum speed. Specifically (as mentioned before) small files do not copy at the same higher rate as large files due to OS overhead and anti-virus protection (if applicable). Also, the speed of the computer's drive affects the real world results. Copying from an SSD drive achieves a higher transfer rate than a traditional spinning disk. I also expect some USB 3.0 capable ports are running at 2.0 speeds due to driver issues.When I first received the drive I tested with with a generic speed test tool and received low data transfer rates (only 2.5 times as fast read speeds than USB 2.0 - 170 MB/Sec read 38 MB/Sec write). I then tested using CrystalDiskMark with the file size set to 1000MB and received the advertised speeds (244 MB/Sec Read & 147 MB/Sec write).Benchmarks and theoretical speeds are fine but it's the real world file copy speed that I'm interested in. Using two files totaling 5.5 GB, copying from an SSD took one minute which is 91 MB/sec. That's close enough for me to not look into it further right now because those same files took 4 1/2 minutes to copy to my old 16GB USB 3.0 drive (the size of the flash drive makes a tremendous difference in speed which you can see by looking at their rated speeds). This isn't a fair comparison but the speed increase is why I bought a new one.Keep mind that the rated speed is always best case or theoretical and that your speeds will almost always be lower. How much depends on your system and how you're using it.I took away one star for the thickness. My work PC has recessed USB ports and other similar USB drives are slimmer.As always, Amazon delivered as promised with a good price and shipping quickly.

I have now owned this for 8 years. It has served me well for all the transfers I do. Still fast and reliable. You can't go wrong with Kingston.

Muy buen producto, trabajo muy rápido, no se calienta, un poco caro pero vale la pena por su capacidad y velocidad

Una pennetta con dimensioni "importanti", i materiali sono solidi con un rivestimento di plastica gommata.Difficile da perdere ma facile da tenere in tasca o in borsa. Alcuni hanno criticato il vecchio cappuccio.. beh meglio di altre marche che ogni tanto si impianta il meccanismo di scomparsa dell'usb. (ho avuto 5 pennette sandisk, la prima perfatta, le altre 4 lasciano molto a desiderare..)Appena arrivata ero ansioso di provare la velocità della usb 3.0 .. prima connessione al pc del lavoro (niente di stratosferico ma monta un ssd 120gb+HD 500gb) e in 3-4 secondi i driver sono istallati e la cartella dalla pennetta aperta.La riformatto in ex-fat (era formattata in fat 32), e provo la prima copia: 14gb con velocità massima di 105 mb/sec, sono un po deluso, pensavo meglio, anche se in confronto la pennetta usb 16gb che ho in ufficio non arrivava a 10 mb/sec. Poi capisco il problema, avevo copiato i file dall'hd alla pennetta, riprovo facendo la copia dall'ssd alla pennetta e la velocità di scrittura supera i 170mb/sec con media oltre i 160mb/sec.Che dire.. oltre 16 volte più veloce di una penna usb2 di qualità media.In conclusione la pennetta è veloce, un po costosa ma vale ogni euro speso, la sfrutterete al 100% solo se avete un ssd nel pc o un hd molto veloce. Un hd sata 6 classico non riesce a starci dietro perchè ha una velocità di scrittura/lettura più lenta e farà da collo di bottiglia, le (poche) recensioni negative che ho letto direi che sono da imputare a questo e non alla pennetta in se.PS: la sto provando anche su altri pc, a differenza di altre marche non ha problemi di compatibilità in usb 3.0

recu 1 jour plus tot que le jour prévu, j'ai admiré la beauté de cette clé où j'ai eu hesitation d'ouvrir le paquet tellement la clé était belle dedans !une fois déballé, j'avoue que la clé est sublime a voir.elle est en revanche tres grosse et ne pourra pas etre utilisée sur des ports à proximité quand c'est l'un au dessus de l'autre au risque de tordre les clés.coté perf :- lecture : 228mo/s c'est un peu moins qu'annoncé- ecriture : 158mo/s là c'est en revanche bien mieux mais pour mon cas, aucune utilisé, c'est a 99% que lecture que je l'utiliserais- petits fichiers 4k qd32 lecture 9.219mo/s ecriture 0.976mo/s ce qui est plutot excellent quand on voit les autres hdd, ssd, clés, cartes mémoires sur les mini fichiers.ce sont les données sur crystaldiskmark en scan 1000mb 3 passages.en pratique, j'ai copié dessus des fichiers de plusieurs mo et surtout des dossiers de fichiers txt et dll de moins de 4ko et j'avoue avoir été surpris de la rapidité pour copier ces minuscules fichiers (il y en avait pour 2.97go tout de meme !) depassant largement le debit annoncé par crystal car je voyais pour ce dossier là (copie de juste ce dossier de mini fichiers), win7 annoncait une copie a 4.9mo/s constant vers la clé.la clé ne chauffe pas ou si peu, meme apres en lecture de gros fichier de 15go.elle semble d'apparance a la fois costaud (par le caoutchouc protecteur) et bas de gamme (plastique) mais d'apres les avis, elle est performante et endurante.seul point negatif où j'hesite a mettre 1 etoile de moins : le capuchon. il se retire facilement deja quand il protege le port, mais pour le fixer a l'arriere de la clé, là ca ne sert a rien, ca ne tient pas du tout. ca fera donc comme ma corsair, le capuchon finira par etre perdu dans le temps...pour une meilleure compatibilité laissez la en fat32. mais si gros fichiers de plus de 4go que vous ne voulez/pouvez decouper, formatez la en ntfs. sinon autre possibilité, faire 2 partitions, une en fat32 et une en ntfs.

Hab den Stick nun fast ein Jahr und er funktioniert immer noch tadellos.Der Stick wurde bisher an jedem Rechner einwandfrei und meist blitzschnell erkannt (USB 2.0 und 3.0).Geschwindigkeit usw. ist ja in genügend anderen Rezensionen bereits angesprochen worden, ich konnte mich bisher nicht beschweren.Vor ein paar Monaten ist mir ein Malheur passiert: Der Stick ragte am PC nach vorne heraus und mir fiel eine Tasche drauf.Der USB Stecker war danach ca. 45° nach unten gebogen und ich hatte fest damit gerechnet, dass er nun hinüber ist.Aber er hat wider erwarten einfach weiter funktioniert, als wär nix gewesen. Hab dann die Daten erstmal gesichert und anschließend den Stecker wieder ein wenig zurecht gebogen, damit die Kappe wieder drauf passt. Keine Auffälligkeiten seit dem Vorfall.Ich hatte vorher Sticks von Corsair, Sandisk und MyUSBStick (Samsung?) die allesamt nach etwas weniger als einem Jahr einen kompletten Datenverlust erlitten (man konnte fast die Uhr danach stellen). Der Kingston hält jetzt schon länger als jeder seiner Vorgänger.Es gibt ein paar kleinere "Macken", die mich allerdings nicht sonderlich stören:- Stick ist recht dick und breit; blockiert daher evtl. benachbarte USB Ports.- Die Schutzkappe ist recht wackelig, hält aber auch nach einem Jahr noch relativ gutVon mir daher 5 Sterne.
