This review is from: Belkin F4U058tt SuperSpeed USB 3.0 4-Port Hub
Pros: Small, low-profile. Mine came with a 4' USB 3.0 cable, which is perfect to reach from the back of my mid-tower case to the top of my desk. Flawless operation.
Cons: Comes with a 'wall-wart' power supply rated at 5 Vdc/4A, and the cord is only 1 m long. This is shorter than the supplied USB cable and may constrain placement of the device. (You don't need the power supply for the hub to function, but to get 900 mA/port from the hub I expect you'll need it.)
Other Thoughts: Not a lot of documentation available. Would have been nice to know the cord lengths before buying (which is why I'm writing this). There are four blue LED indicators 'hidden' on the top face that indicate a connected device on each of the four ports.
I did NOT see any speed penalty when using my USB 3.0 card reader, USB 2.0 keyboard and USB 2.0 mouse all connected through this hub; I was able to read from my PNY P-SDX64U1H-GES3 at 90 MB/sec with the mouse and keyboard connected. I knew USB 2.0 devices were supposed to work, but I wasn't sure if the USB 3.0 devices would continue to operate at 'super' speed. I'm going to dock my tech knowledge one egg for not knowing this. :)
Pros: Fast transfers, rated 90 MB/sec reads and up to 60 MB/sec writes. I have seen 85-90MB/sec reads from the card, but when reading 100+ files totaling 4 GB, I got more like 77 MB/sec. I'm writing to a Vertex 4 SSD, which shouldn't be slowing things down. When I wrote a 1.8 GB file to the card I got 55 MB/sec. This was with a Transcend TS-RDF8K USB 3.0 reader on a Win 7 system with Gigabyte GA-Z77XUD5H motherboard, Vertex 4 SSD and i7-3770k processor.
Cost. A certain 64 GB "Extreme Pro" card is 3x the price. Yeah, the write speeds are slightly slower on this card (60 MB/sec vs. 90 MB/sec) but I don't really need that and I couldn't overlook the price difference; in fact I bought two of these.
Cons: Another reviewer pointed out that you should hang on to your packaging and PNY doesn't warrant against data loss. I haven't had issues so far, but it's only been a week.
Other Thoughts: Bought for a new DSLR that has 2 SDXC slots. No regrets. I don't think I'll be shooting anything fast enough to hit the write limit on these cards. 1920x1080 30 fps video doesn't seem to stress the card either.
Gotta love Moore's Law; these cards are faster and have more capacity than any camera card I've ever had, though in a few years they will likely be obsolete (another factor I weighed when deciding if the bleeding edge cards costing 3x were worth it).
Pros: USB 3.0 for faster transfers. I was can hit read speeds of 85-90 MB/sec with a PNY 64 GB SDXC card (P-SDX64U1H-GE) rated at 90 MB/sec read, 60 MB/sec write. With this card I got 76 MB/sec copying 145 files totaling 4 GB off the card, and 55 MB/sec copying a 18 GB file to the card.
I was able to get read at 30 MB/sec (the rated speed) on an older 16 GB SD card, which I couldn't do with my old USB 2.0 reader.
It's small, inexpensive, and I like the styling. No drivers seemed to be required, Win7 found it right away.
Cons: The supplied USB 3.0 cable that came with my unit is only 18" long. I'm using a Belkin F4U058tt USB 3.0 hub on my desk which came with a 4' cable, so the short cable isn't a big con for me. I thought someone might want to know. Transcend didn't specify the cable length, so I suppose you may get something different.
The LED indicator is basically on if the unit is powered and will blink if there's any data access happening. I wish it would go off if I eject the SD card, but it doesn't (probably because it's shared with the microSD and CF ports).
Other Thoughts: The "convenient LED indicator" is blue and is located on top, at the left edge aligned with the "(T)Transcend" printing. It's not blindingly bright, which is good in my book.
USB powered, but that was expected. I'm running Windows 7 Pro 64-bit on an i7-3770k and using a USB 3.0 port on my Gigabyte GA-Z77X-UD5H motherboard.
I bought this to go with a new DSLR that shoots 28 MB raw files, so the speed is nice. Good reader, no regrets!
