There was a problem filtering reviews right now. Please try again later.
usb stick has now failed. i removed it from the shield because plex was struggling transcoding due to a very slow buffer. didn't realise it was the usb stick until i reformatted it and tried writing some files to it. a 4gb file was showing 6 hours and was stop/start/stop/start when copying.
disappointed as initially this was a good usb stick, and not being a fan of the durability of their micro sd cards i thought i had found a winner. sadly not
There was some clutter on the sticks taking up some valuable space when first examined, but I always reformat new media to remove any possible Trojans etc and NTFS is a more robust file system than exFAT. I also always test them to check for speed and capacity.
At first sight the retractable plug is handy, but the contacts are still just as exposed to dust dirt and static. So in reality this feature is simply a gimmick and a waste of space, and these sticks end up being about 2cms longer than normal sticks which makes them more vulnerable to accidental knocks while plugged into, say, a laptop.
H2TestW gave me an average write speed of 35.2MBytes/s and 57:12 minutes to write the whole chip, double the speed of the 128GB Sandisk Ultra chips, and steady between 35.5 and 35.0 all the way through. However, I have seen this test write between 95 and 105Mbytes/s on the older 32GB Sandisk Extreme USB3 devices on this machine, almost three times faster, so it is definitely the chip that is slowing it down.
Read speed is much better, at 135Mbytes/s and 14:52 minutes to verify the whole chip, but still does not fully exercise the USB3 interface, and still slower than the 32GB which were about 168Mbytes/s.
Storage is shown as 117GB available on the PC, actually 126,533,763,072 bytes, when formatted as exFAT with default sector sizes. NTFS has a slightly bigger overhead so slightly less available storage at 126,452,592,640. There were no bad locations on either of my two samples.
The chip runs at about 15°C above ambient, nowhere near as hot as some I've tested, but then it is not working as hard. This is actually a good thing, because running cooler should maximise lifespan and reliability.
I have specifically ignored the Sandisk encryption system because I don’t know anything about its provenance and also because it is an all eggs in one basket system. If it is unavoidably necessary to encrypt any files I’ll do them individually with software I know and trust, and give each a unique pass key.
Design is exactly like on the promo shots: full-black with shiny strip and blue LED hidden underneath it. When the drive is connected, it glows in "breathe" mode and when you copy/read data, it turns into pulsing mode. The diode is strong enough to be easily seen, yet not too much which would annoy/distract the user. Simple, informative, nice looking. As for the case, aluminium would be more in place just for the sake of looks (temperatures aren't an issue here, at all), yet Sandisk keeps sticking with plastic.
Plug's ejecting and hiding mechanism feels solid enough for many years of use and helps reducing already significant length of the drive.
Speeds are exactly like promised: 150 MB/s write is in range synthetically or on many small files, while on larger files You achieve stable 100 MB/s.
Overall: great pick for power users, operating on large amount of data and expecting highest speeds possible. While the looks can seem cheap (big size & plastic case), it's the components that count. And that's where the Sandisk smashes the competitors.
Had it for 11 months, rarely use it as it is so slow. Just done some comparative tests and it is significantly slower than an old usb 2.0 Bytestor 32 GB flash drive. It is clearly not fit for purpose and I don't see why I should just throw it away. But cannot find how to return an 11 month old flash drive to Amazon. The return panel doesn't show up for it. .Can anyone advise me please?
Name: SanDisk Extreme Go USB 3.1
Size: 64 GB
The plastic on the switch to extract the USB rattles a little, but this doesn't bother me. Did a speed test. The sequential write was a little slower than I expected, but 70 MB/s is still really good.
This is USB 3.1 v1 and so is backwards compatible with older PCs but will potentially be a little faster if used on a USB 3.1 socket. There is no option for USB C but there are adapters if required.
It is quite fast and earlier versions of this drive (USB 3.0) have been successfully used for some time.
