Excessive heat during data transfer caused my UltraFit to fall apart!

Excessive heat during data transfer caused my UltraFit to fall apart!
*** Update - 3/5 Stars - 04 JAN 17 ***I called SanDisk on 15 DEC 16 to organise a RMA and was instructed to send the faulty UltraFit to my nearest SanDisk head office (Sydney, Australia) at my own cost. Once they received the faulty unit I was given a tracking number for the replacement. To my surprise the replacement UltraFit was being sent to me via international expedited mail from the US (I live in Australia).I am very impressed with SanDisk's global warranty and to their credit, the entire warranty process has been easy and straight forward.The replacement UltraFit arrived today (04 JAN 17) and within a matter of minutes of using it, I noticed the same heat issues which plagued my previous unit. I share the same concerns I had in my original review but will give this new UltraFit the benefit of the doubt for now.*** Original Review - 1/5 Stars - 27 SEP 16***I purchased a 128 GB Sandisk UltraFit in August 2015 and have used the drive fairly regularly since then. I would probably classify my usage as ‘average’ with most of my data transfers taking between 5 - 15 minutes to complete.The UltraFit does get very hot during normal usage (even during short 2 - 3 minute transfers) like a lot of other reviewers have mentioned but I didn't encounter any issues until I used it to backup a large quantity of data from my PC in preparation of a format > reinstall.On this occasion, I was transferring large amounts of data between two computers (copy files from PC A > paste files to PC B > clear UltraFit and back to PC A to copy files again > etc). After about an hour or so, I went to pull the UltraFit out of my USB port and to my surprise/horror the black plastic top (where you attach your lanyard to) separated from the metal portion. The metal portion was still stuck in my PC and the plastic top was in my hand!I tried to pull the metal portion out of my PC but it was too hot to touch. After letting it cool for a couple of minutes, I managed to remove the metal portion and reassemble the UltraFit together long enough to get my data off it. I can only guess that the heat generated during the transfer caused the plastic/metal parts to expand/deform enough to 'pop' out of the hinges holding the UltraFit together - you can see a metal hinge and a plastic hinge in the attached photo (there isn’t any glue/adhesive holding it together).Before buying the UltraFit, I had read through the comments section and noticed the warnings relating to the heat produced by the device. I took a gamble and purchased it anyway as it was at the right price point for speed and capacity on offer. I thought the heat issues would be manageable, but I guess Lady Luck wanted to prove otherwise >.<;I have owned a number of SanDisk drives over the past couple of years and they have been nothing but reliable. In this case, I am very disappointed with the build quality of the UltraFit and guess that I have no one to blame but myself for ignoring the warnings by previous reviewers.I would not recommend this drive to anyone, especially if you are planning on using it for any prolonged period of time. The heat generated by the UltraFit will likely shorten the lifespan of the device and even cause it to literally fall apart!

5.0 out of 5 stars I'm very happy with this drive
Reviewed in the United States on January 5, 2016
Summary: I'm very happy with this drive. The cost per unit storage is fantastic, the size is just right, and the speed is good. The plug-and-forget capability makes it a viable way to extend the storage of a laptop.
Details: Neither of my initial concerns have proven warranted. I was concerned about the complaints of heat. While it is noticeably warm, it's not hot by any reasonable standard. I was also concerned that it might protrude from my laptop enough to snag and cause problems. Also not a problem.
As the first USB 3.0 flash drive I've owned, I expected to be pleased by the improvement in performance. While the drive is slower than some other USB 3.0 flash drives, it is still quite fast. I haven't been able to replicate outside of benchmarks the 30 to 40 MB/s write speeds that some have observed, but I have seen average writes of between 20 and 25 MB/s. This was done using the Linux pv command to track the transfer rate of 3 very large files (18GB, 19GB and 8GB) to the drive. Attempting the same transfer with a Sandisk Cruzer 64GB USB 2.0 flash drive resulted in rates of 3.5 MB/s to 4.5 MB/s. So, while I cannot verify the claim of 10x the transfer speed of USB 2.0 devices, I do find the speed satisfactory. It would certainly fall short for anyone that wants to, for example, run a VM from the drive, but most day-to-day bulk storage write needs will be readily met by the drive.
Similarly, read speeds on the drive are quite satisfactory. Reading the 3 very large files from the drive to /dev/null through pv showed a transfer rate of just over 100 MB/s. While this again falls short of manufacturer (idealized, no doubt) claims, I am not at all disappointed.
CrystalDiskMark on Windows gave results somewhat higher than those I achieved in practical usage. I include them as another measure, although I obviously find the practical measures more useful.

Reviewed in Mexico on January 19, 2016
Se puede decir mucho de esta memoria. La relación calidad/precio es excelente, ya que el precio en tiendas suele ser de casi 40% más de lo que cuesta en Amazon, los tiempos de envío son extraordinarios y Sandisk es sinónimo de calidad.
Como estás leyendo reviews, quizás deseas saber un poco más de lo que ofrece esta memoria, así que trataré de cubrir todo lo necesario.
1) Tamaño. Es una memoria muy pequeña, incluso puede pasar como un adaptador de un mouse USB, sobresale un centímetro de la base de tu computadora, lo que la hace ideal para tenerla de almacenamiento "semifijo" en dispositivos como Laptops o tabletas "Surface". Anexo fotografía de cómo se ve en mi laptop para darte una idea. No estorba, no molesta ni nada por el estilo. Incluso posee un pequeño protector para traerla en tu bolsa o maleta. El problema que más de uno hace notar, es que por su mismo tamaño es posible que la olvides, que la pierdas en algún lado o la dejes en la bolsa del pantalón (y termine en el ciclo de lavado y centrifugado, lo que no es nada bueno).
2) Capacidad. Varía dependiendo tu gusto, en mi caso me hice de un par de memorias de 64GB, lo cual es suficiente para mover archivos sin problema, el precio (menos de $350, al día de la reseña) la hacen ideal, ya que en tiendas minoristas, la memoria de 8GB (en USB 2.0) te sale en menos de 100 pesos.
3) Velocidad. El USB 3.0 te cambia la vida, especialmente si mueves archivos de gran tamaño (como videos o fotos/diseños de alta calidad), ya que, por diseño, es al menos 10 veces más rápido que el USB 2.0, me tomé la molestia de hacer una pequeña prueba de lectura/escritura con mi equipo y los resultados son más que rescatables. En promedio, la velocidad de lectura es de 142.45 MB/s y de escritura es de 82.30 MB/s, llegando a casi los 100 MB/s (la prueba se hace usando archivos grandes, por que siempre será más lenta la transferencia cuando hay muchos archivos pequeños). Anexo una gráfica de rendimiento.
4) Software: Posee un software para poder encriptar tus archivos y protegerlos, esto le reduce un poco su capacidad, obviamente, pero sirve si tienes información importante en ella. Para que pueda funcionar en MAC, necesitas descargar el software desde una liga que te dan en el empaque.
5) Amazon: El servicio es excepcional, llega en unos días de haberla adquirido (en especial si es importada), pero si logras juntar artículos, tu envío es gratis y el empaque viene muy bien protegido. Así que por eso no te preocupes, es una garantía.
Una compra necesaria. Excelente por donde se le vea.
