You can do this by writing about 16GB of different files to it, or just saving the same 1GB file 16 times. So in the case of a 16GB flash drive, you just have to write 16GB of data to the drive for the write speed to start to degrade. Flash drives do have wear leveling in them, so even if you save the same file over and over again, it will write that file to different cells. It just means you have to write enough data to use every cell in the drive. But once you have written enough data to the drive that every cell has been used, write speeds drop, because from that point on it has to erase the cell before it can write to it.Īlso, this doesn't mean you have to fill the drive up before this happens. So they they are new, write speeds will be good. However, almost no USB flash drive, especially cheap ones, support any kind of TRIM or garbage collection. One of the down sides of using NAND flash for storage is that once a cell has been used, it has to be erased before new data can be written to it again. These drives, according to all tests confirm these drives are not dead!!!
Restore the drives to their original "write" operating speed. Identify and correct what caused the slow-down problem #2. I could provide much more info about what I've done concerning testing the drive, but unless requested(for it's an extensive list), I'll omit that. all drives have been used, in what I'd consider, moderate to little operation. None of the drives in question are older than 2 y/o and one (Sandisk Cuzer Glide 3.0/256Gb) is less than 9 mos. Right now, I'm transferring a 9.6Gb file and the rate is fluctuating between 1.38-3.26Mb/s.(Lenovo ThinkCenter-Win10). On the Kingston I've also wiped/rebuilt partition, formatted in both NTFS & Fat 32, tried a formatting tool directly from Kingston Inc. I've done an extraordinary amount of tests on the drives and all the tests have concluded the drives are operating correctly with no "defects" detected (healthy). Could someone head me in the right direction of understanding what would cause the sudden slow write speed and what I may be able to do in order to restore the drives to their original write speeds. My limited knowledge has led me to question the "gate"(I hope that's the correct term) of the drive. This seems to be a rather common occurrence among flashdrives, and after going through many, many forums, the net and articles, I have not found a definitive explanation, nor a common "cure" to this anomaly. One time it ran 5.5+Mb/s the, next time 1.8-2.3Mb/s.(using Win7) I checked my other "drives" and found 5 that have the same problem. DTSE9/16GB Kingston DataTraveler SE9 16GB USB 2.Recently, I noticed the write speed of a Kingston DT101G2 16Gb dropped considerably.All Kingston orders are shipped within 24-48 hours after the order is placed if they are not on back order.
