This review is from: Patriot SLATE 3.0 32GB USB Flash Drive Model PSF32GLSS3USB
Pros: Low Price
Cons: SLOW SLOW SLOW SLOW
No activity indicator LED
Other Thoughts: I compared this memory read/write speed on a USB3 port, on a linux laptop using DD with 4MB block sizes to read/write a 1GB file. Write speed is about 4.6 MB/s, read speed about 21MB/s. I ran the same test on an old 16GB usb stick for comparison. The old USB2 stick is over TWICE as fast as this new USB3 stick. Read speed of the USB2 stick was slightly lower than this new USB3 stick but very comparable.
My recommendation is DO NOT BUY if you care anything about speed. This thing is slower than molassas in January.
Pros: 1) seamless hardware and software connection
2) opens three new USB 3.0 ports
3) improved performance over native ports (???)
4) power for small external drives
Cons: None so far
Other Thoughts: As part of my political job I handle databases of many gigabytes on a daily basis, and need back them up. Consequently I have three terabyte+ disk systems attached to my laptop via USB. My laptop has two USB 3.0 ports, so I wanted a hub. This hub is ideal – I can attach my three drives to the hub and free up a USB port on my laptop. And, it provides power to one of otherwise unpowered disks.
On receiving the hub I ran some diagnostics to see how big a hit it would cause in backup speed. Logically one would expect some hit because there is another port for data to traverse. The data indicates otherwise – read and write speeds through this hub are actually faster than going directly to the laptop's built-in USB ports. Go figure.
I use Linux (Ubuntu 14.04) and tested speeds with the dd utility, reading 2048 blocks of 4 MiB. Here are the results:
write, with hub, 8GiB file:
8589934592 bytes (8.6 GB) copied, 98.5147 s, 87.2 MB/s
write, direct, 8GiB file:
8589934592 bytes (8.6 GB) copied, 103.329 s, 83.1 MB/s
read, with hub, 8GiB file:
8589934592 bytes (8.6 GB) copied, 102.382 s, 83.9 MB/s
read, direct, 8GiB file:
8589934592 bytes (8.6 GB) copied, 103.345 s, 83.1 MB/s
Considering that this hub can be had for about fifteen bucks with proper shopping, it's a great deal.
Pros: * SPEED: I tested the card for speed on a Linux laptop with a built-in SD slot. Using the Linux "dd" command to transfer a 1 GB file, read and write speeds were in excess of 20MB/second. I can't say how much faster the card is because the speed was limited by the bandwidth of the internal USB channel the connects to the SD slot. Many odd-brand SD cards don't live up to their advertised speed ratings. This card does, and more.
* CAPACITY: This card, when reformatted (SDXC) using the SD Association official formatter actually delivers its advertised capacity of 64+GB. Most other SD cards, regardless of brand, don't deliver their advertised capacity when formatted to the official standard.
Cons: None so far, but I've only had the card for a bit more than a day.
Other Thoughts: (Whatever card you buy, it is suggested that you reformat it to the official standard using the formatter available from the alliance of companies known as the SD Association. Doing so will maximize the performance and longevity of the card. Other off-the-wall formatters or native OS formatters may not.)READ FULL REVIEW
