It is the amount of space that it says. Is very fast when you transfer data. I love I can use it in my cellphone. It has a good way to protect the ports and is not a top so I will not loose it

This is a fairly decent 2-in-1 flash drive. It has a port on either end, one is a standard USB while the other is a type C USB. The access throughput is reasonably fast and the capacity is usable. i have much smaller thumb drives of either connector in the multi terabyte range, so this is more of a utility drive for when i need both connectors as opposed to a fast, or big, or fast and big drive. Because of the dual connectors, it works quite nicely as a transfer unit and with the price, i would recommend it for that purpose as well. We shall see how its durability fares but after two weeks of daily use it seems to be coming along nicely.

This Aiibe 128GB thumb drive provides the flexibility of dual USB A/C connectors in a novel-looking red and black plastic case. There is also a red indicator light to let you know file transfer is taking place. It is unfortunate that the manufacturer decided to use the older USB 2.0 standard for this drive, however, since it slows the transfer rates down significantly. To evaluate the drive, I first plugged the drive into my desktop PC and scanned it with Kaspersky to verify it was clean. File explorer showed a capacity of 125.8GB, verifying that it is a standard “128GB” drive, but it also indicated that there was only 117 GB of capacity available for files, due to a large payload of onboard software and/or cache. READING data from a flash drive is always faster than WRITING data to a flash drive. So, when I comparison test a high-capacity flash drive, I write the same standard batch of 998 data files (1064 total items including folders, equal to 6.40 GB), from my Windows 10 desktop machine, through a USB 3.0 port, to the flash drive. The MS File Explorer pop-up window provides continuous transfer rate data during this write operation. Monitoring that window gives me the peak transfer rate I’m looking for and plots the variation in transfer speed throughout the write task (see photos). This Aiibe drive completed the 6.4GB write-test in 22:26 minutes. This is the longest time I’ve ever recorded for file transfer to a 128 GB thumb drive. The average transfer rate over the 22 minute test of this drive was 4.7MB/sec, with a maximum speed of 24MB/sec and a minimum speed of ZERO – yes, Zero – The drive froze for several seconds, multiple times throughout the transfer test and registered 0 KB/sec in the pop-up window. For comparison, over a year and a half of prior tests, the fastest dual USB A/C 128GB drive I tested had a peak write speed of 65.4MB/sec, an average transfer rate of 42.3MB/sec, and took just 2.5 minutes to move this set of test files. That fast drive (and many of the others I tested) was a USB 3.0 drive. Despite the long duration of the write-test, I did not detect any temperature increase in the drive case; this is often an issue with many high-speed 128GB flash drives that I’ve tested and can be a concern. Typically, hardware that runs cooler tends to last longer. In conclusion, this drive has a high capacity and works properly, albeit slowly. It would not be my first choice for a high-capacity drive.

Useless! Upon receipt I attempted to run a read/write/capacity test, the first thing I noticed was that the drive was SLOW, like really SLOW! There appears to be a cache for the first few hundred MB but after that it comes to a screeching halt and trickle writes at low-end mediocre USB 2.0 speeds... After about 5 hours, the read/write test was completed with multiple bad sectors... So I figured I would format it and try again, 5 hours later for a full format and I attempted to run the read/write/capacity test again and it started to toss out multiple write errors and bad sectors almost instantly, then about 10 minutes into that test the drive became unresponsive and was no longer detected properly by Windows... I have attempted to recover the drive to no avail, I plugged it into an Android device and the Android device crashed, so all I can assume at this point is that there is a hardware fault inside the drive, rendering it entirely useless...

USB C + A flash drives are an inherently clever innovation. This one is particularly clever because its dual sliders let you expose (or cover) both connectors, or either, or neither. Also, the plastic housing is unusually lightweight, but feels sturdy enough to hold up well. The geometric design looks stylish (in a Tetris way) and has a good tactile feel. The drive comes preformatted as ExFAT, for Mac/Windows cross-compatibility. There are a couple of downsides: The housing is fairly wide in order to accommodate the sliders, so on a MacBook with 2 USB-C ports jammed right next to each other, you can use only 1 when this is plugged in. Also, if you're prone to misplacing flash drives, this has no loop to run a cord through. But on the whole, I'm pleased with it.

Being that its an OTG style drive with USB C and USB A I thought it was pretty cool idea but at the end of the day you'll probably go wayyyyy faster just plugging it in your computer but if you don't have that option then this is an alternative. Just for comparison my 128GB Samsung FIT shows up as 128GB (119GB formatted), this one is from VendorCo ProductCode, comes 125GB (117GB formatted). They do have in the specification a slower speed so it is performing "faster" than its specified but compared to todays standards its a bit slow. You have a lot of other microSD speeds much faster than this so if you're looking for an absolute taking files off your phone for storage or storing it to another device without a cable then its okay I guess. I tried testing out 700mb of data and it took a while, just plugging it in would be better.

This is a nice compact thumb drive with great capacity. I am very impressed with the robust sliding mechanism which feels solid going back and forth between open/closed on both sides. Much better than say the typical SanDisk mechanisms. It has both USB-C and USB-A so the optimal use is transferring files directly from phone to PC/Mac or vice versa, preferably your own machines. The weakness is the speed which seems to top out around 20MB/s, which is to be expected in all fairness. Another disadvantage is the formatting which is exFAT because it's non-journaled, but if you are going to want compatibility between iOS, Mac, and Windows, there is really not much in the way of alternatives. All in all, this is a very handy tool built really well. I experienced no problems with trial runs on both iOS and Windows.

I had no need for another USB 2.0 thumbdrive, but I was really curious about this being so inexpensive and liked that it had both USB-C and USB A connections built-in. The drive performs well for the first 2-2.5GB. After that, read/write speed and IOPS plummet to essentially zero. The drive never drops off USB and seems to eventually respond, but is basically unusable beyond 2GB. I suspect the capacity is as advertised, but the particular NAND chip is just a poor performer once SLC cache is exhausted. It seems to take forever for the chip to commit SLC -> QLC and does so in ~28GB bursts so I reckon that is the SLC cache size. -So if you stay within that range, performance will be quite good. When staying within the 2GB range, performance is average for a USB 2.0 class thumbdrive. After having miserable results with the default 128GB (117GB) exFat partition, I reformatted as a 2GB NTFS ignoring the rest of the SSD. Results were more consistent when formatted this way. Key facts: - Generic firmware with identifier strings "VendorCo" "ProductCode" - Vendor ID: 0x346D - Product ID: 0x5678 - likely manufacturer: Shenzhen SanDiYiXin Electronic Co.,LTD - USB 2.0 speeds on both USB-C and USB A connectors - Internal PCB markings: KT-G2_FC2279Q_1T1B_Type-C 2023/11/09 V1.1 - exFat filesystem - low power consumption at 100mA peak Some positive testing notes: - write: ~24.5 MB/s average for 1GB transfer on empty drive (drops to ~9MB/s for fuller drive or longer writes) - read: ~27 MB/s [1GB transfer] - accepted NTFS format - survived ValiDrive tests - BurninTest passed 1% random Overall, I would not recommend this product.

This flash drive is a dual-connection USB-C and USB-A device with 128GB of storage. I was able to successfully write to and read from/verify the entire drive, so the capacity is legit. It has an unusual mechanical design that allows both connections to be exposed simultaneously, but you definitely shouldn't connect this to two devices at once or attempt to use it as any sort of adapter - it really should have a better case that protects one connector when the other is in use, like most other flash drives of this type. This is only a USB 2.0 flash drive, and it shows in the miserably slow transfer speeds. I used H2testw to verify this drive, and it took five hours to fill the disk with data at a write speed of 6.52Mbyte/s. Reading was better, somewhat - it took two hours to read everything back at 16.4Mbyte/s. This is totally fine if you're just copying a few small files here and there, but if you actually want to use the full 128GB capacity, you'll be sitting there for literal hours trying to fill it up; a USB 3 capable key would be a much better choice. I was also not able to run f3write on this drive. Unusually, it ended up writing with incredibly slow transfer speeds - much lower than expected. I'm not sure why that occurred, as H2testw on a Windows PC and Finder on my Mac were able to write to the drive fine, so I'm going to chalk it up to an f3write issue - but it's worth noting I use this toolchain with many other drives for quality testing without any problems. All in all, this is a cheap option with dual connectors and a nice appearance, and the full capacity is legitimate - but I can't recommend it at this speed-to-size ratio.

This drive is definitely not the fastest I've used, but it does work. It connected to both my phone and PC without issues and has the expected capacity. I wouldn't recommend it for transferring or storing large or important files, but for transferring a few things between a phone and other devices, it works just fine. The sliding covers to protect the USB connectors are a nice feature as well. Overall, you can probably find larger capacity or faster drives with the same physical size and features, so I would compare this drive to those based on price and your use case.
