Adata reliable?

[mintydroid]

Hi guys

Looking at purchasing Adata usb 2.0 flash disks for faster read and writes. Are they reliable products?

I haven't used any Adata products and neither have my friends or family. I have had my share of microsd's randomly dying and I'm hoping it's not the same with flash disks.

Yes.

I recently bought one of these Adata USB 3.0 flash drives from Takealot. Really good speed for the price even on a USB 2.0 port.

I've also had good experiences with their USB 3 flash drives.

I've used their external drives and RAM, no problems.

I'm thinking about purchasing the Adata UD310 16GB for extra storage on B+ Raspberry Pi's I'm planning to purchase. I'm mainly choosing them because of their nano size and price.

It benches decently on Crystaldiskmark which is faster than my current disks.

A write speed of ~7MB/s is quite low for a modern flash drive. I think that the 32GB UV128 will write at close to 20MB/s on a USB 2.0 port and much faster on a USB 3.0 port. Just check some of the reviews on Amazon UK/US for some benchmarks. Stay away from those cheap Patriot Xplorer flash drives on Takealot - most of them only write at 4~5MB/s. There can be a large spread in the performance of the same brand/model of flash drive - I bought 7 of these 64GB Transcend drives and the write speeds vary between 8~12MB/s. The Patriots usually vary a lot more.

I always trust Transcend, Jetflash 700

Please link to their nano/micro flash drives, if they have?

Just go to Takealot and search...

Here are the read/write results for the UV128 32GB flash drive from a USB 2.0 port if anybody is interested. The flashbench utility can be downloaded in the second link for comparison purposes.

I'm looking for usb 2.0 because the the wifi dongle I want to use is only 150 megabits so theoretically only 15 megabytes per second read and writes excluding any overheads.

My external harddrives are usb 3.0 if I need to move mass data.

@RM: Just download that flashbench software and test out a few flash drives. You will see that the write performance of the UV128 drops off drastically as the file sizes are reduced. You can only expect write speeds of around 2MB/s on small files. In this case the UV128 could be more than 10 times faster (2MB/s vs 0.2MB/s etc.) than a generic USB 2.0 drive which are usually much worse at writing small files. The price difference between the cheapest 32GB drive and the UV128 is only about R18 so it's not worthwhile to buy large USB 2.0 drives any more unless you need a really tiny form factor for example. Lots of customers are booting their NUCs from fast flash drives similar to the UV128.

Form factor is a criteria. Don't want to break the port mistakely with a too long usb. I had looked at the Kingston Duo OTG and Verbatim Nano. Kingston overheated and the Verbatim was just too slow 4 megabyte/second writes and 10 megabyte/second reads.

UD310 is R70 for 8gb and R111 for the 16gb.

Got the disk. It's really tiny and exactly the form factor size I was looking for. It the same size as my wifi dongle.

Dongle on top and usb at the bottom.
