Hi!
I'm searching for a good quality, high capacity and fast r/w usb stick.
I found two of them which maybe come to count by me.
Are they any good:
1. Kingston DT100G3/256GB
2. Kingston DTKN/128GB
I would like to buy the 1. option.
What you think about these two sticks?
I need them for temporary backuo and transfer huge amount of data from pc to pc etc...
Thanks for any suggestion.
Kingston has been in the memory business quite awhile, I have an old Kingston USB Thumb drive that works fine but is too small capacity for most usage at 1GB. It probably would be best to match the port type to the drive type, USB 2 to USB 2 or USB 3 to USB 3. USB 3 is supposed to be backward capable with USB 2 and usually is.
Yea, they are backward compatible.
Im mostly interested in th r/w speed.
On the 2. usb the manufacturer give the r/w speed but on the first they wrote only the reading speed.
I have several usb flash drives ~16 - 64gb but some of them are so slow...
One thing I have to allow for in copying/moving/transferring data to USB drives, all types, is that the source data is read, temporarily saved in memory then written to the destination. It simply takes time. The motherboard, CPU speed and amount of RAM have an effect on the process. Rebooting to clear the memory before starting a large transfer can help.
If those data files are important to you, consider getting twin Kingstons, saving important or critical info on both, especially for backup purposes and "sneaker-netting". Extra work, sure, however, if one of two goes suddenly bad, the other one probably will work just fine.
That's true, but there are so many USB flash drives out there, who are simply slow in r/w and the r/w process is not stable, it is constantly fluctuating from a minimum up to a max speed. Their controllers are crap and simply not worth the money.
Even if they are labeled as USB 3.0 etc. They simply slow when it comes to a huge amount of r/w.
Some of them are with poor pcb inside, and got hot too.
So, that's just quality issue.
I have experienced that kind of problem on Transcend JetFlash USB 3.0 from 16Gb to 64Gb.
They simply slow.
Then I used lets say the SanDisk Wireless Stick USB 16GB which is stable and much faster ( around 30-40% ) then the previous mentioned flash drive.
Then I connect my external ssd to the same pc, same usb port, that's what we need really stable and 15- 20 x faster r/w then
a normal usb flash drv.
Our PC's are all new generation of i5 and i7 cpu whit ssd inside and 8 - 16Gb RAM.
I'we do not need these drives as a backup drives, just temporary.
- backup from the pc to the usb
- reinstall the pc
- write back the backup from the flash drv.
The data I copying is sometime aroun 100Gb of doc, xls, pdf data + some nice and huge Outlook .pst file.
For this task I use 7z.
Pack all the data for "storage" and then I copy one big file to the usb storage temporally.
I own 3 of the DT100 G3 128GB drives and 2 64GB ones, all USB3, they have been in constant use (as in re written almost monthly) for over a year and they are fine for what they are. Be aware that most flash drives are typically slow at writing, even USB 3 ones, these Kingston ones suffer from that wave form of copying (where the Windows copy dialogue's progress bar literally resembles a wave), a burst of activity followed by a trough of zero activity, repeat till end of write process.
Reading speed is fine.
The write speed is higher on larger single files and much slower on lots of little files, which is to be expected, and the write/ read speeds are pretty constant on an Intel Win10 machine, an AMD Win10 machine and an AMD Linux Mint machine.
My personal opinion, the money spent on the flash drives would be better off spent on an SSD (NVME) enclosure with USB C connection or even regular USB 3, or a decent portable SSD, the only need for flash drives these days is for OS installs and car media players.
UFDs are just very convenient for certain uses. They are small, can be very rugged, and don´t need cables to connect.
A portable SATA SSD can be faster in writing operations, and the speed is more consistent, there is less variation. But it is very much larger and must be used with good quality cables, compatible with the port being used, USB Gen. 1 or Gen. 2.
A portable NVMe SSD is faster but more expensive, can have heating problems, and must be connected to a Gen. 2 port with a compatible cable, to take advantage of its speed.
Does your computer has USB 3.x ?
Read speed is up to 130 MB/s but write speed is unknown and can be much, much slower.
My suggestion is to buy a 2.5" SSD and a good USB caddy. Faster and less expensive.
2.5" Hard Drive Enclosure, USB C 3.1 Gen 2 - Newegg.com
Crucial BX500 480GB SSD - Newegg.com
A USB caddy with NVMe drive inside is the fastest you can get (up to 1200 MB/s on a USB 3.2 port).
