You'll be extremely unlikely to get 3-4 times the performance of the MyMemory 256GB chip, which does achieve 80 write and 140 read on my system using H2TESTW, from my own testing with an Samsung SSD in a standard caddy, it achieved reads of around 200 and writes of 190, but, and it's a big but, the overhead of moving smaller files slowed it right down, so it would only exceed the memory chip speeds when the files were large, Blu-ray images and that sort of thing, jpgs and word documents didn't benefit at all.
Incidentally both the caddy and my PC are compatible with UAS (a much faster protocol for USB designed specifically to speed data transfer), without this feature, it's unlikely you'd get any better performance with a USB3 caddy and SSD.
Given the cost being of the order of 30% more and the size and weight being greater with quite limited performance benefits, for many it wouldn't be worth it.

That's the one. They have been £40 in the past. I quite agree with you, SSD's are practically as cheap, almost as portable (phone sized) and orders of magnitude faster. I picked up mine from the My Memory eBay site because I had a £15 voucher (worked out to be £30). USB can be more convenient. I use mine connected to my TV (so no need to suspend a SSD by an adapter cable) and I have others connected to my router (tidier without a 15cm cable and a 2.5inch lump). We have more USB slots than SATA ports, which means you can connect more USB devices to expand a NAS etc, although as you say there are SATA to USB adapters available for not very much money.
That one? Very impressive for a USB stick. However, for £43 it's getting near the price of an SSD plus a USB3 interface (that's around £10-15 more), which will have 3-4 times the performance.

I've got 4 of these and 1x 256GB, the newer ones all manage transfer speeds well into the 80+MB/s, but my first 2 128GB have speeds similar to these reported and also reported on the last deal thread. It's shame because the fast chips were an absolute steal, maybe there were issues, but all my red chips have proved thoroughly reliable, if a little hot for the fast ones.

I just got mine yesterday for £17. :laughing:
Haven't had to read anything back yet but copying to it topped out at 22MB/s but was mainly a steady 21MB/s

Read and write are around 25MB/s second on all of mine at the top end.
Not quite the USB 3.0 performance that some might not like but at this price .....

Read Speed: 25MB/s
Write Speed: 14MBs
Isn't that really quite slow?

Absolutely. I bought the 256GB version recently which still has the respectable techno bits. My Memory has since made these drives $h!+ by cheap'ing them out with USB 2 grade components. The 256GB version manages 39MB/s read and write solidly. My Memory don't attempt to hide the speeds. I'd grab a 256GB one before they run out of the original components.
