This review is from: Toshiba 32GB Secure Digital High-Capacity (SDHC) Flash Card Model PFS032U-1DCK
Pros: Speed consistently exceeds Toshiba's specs. Reliable brand.
Other Thoughts: Tested in Windows 7 USB 3.0 port (with Etron USB 3.0 MB chipset), using card reader with Genesys GL3220 controller chipset. Results: 12.8-13.0 MB/s write. 31.4-36.7 MB/s read - which easily exceeds Toshiba's published claim of "up to 30MB/s."
Don't assume, however, that any el cheapo card reader with some unspecified chipset can enable this (or any) SD card to perform optimally. Unless you know of something as good or better, consider using a device or card reader utilizing a Genesys GL3xxx series chipset (with upgradeable firmware).
This review is from: HooToo® HT-CR002 External USB 3.0 Multi-in-One Card Reader (4 Memory Slots, Genesys GL3220 Chipset) & SuperSpeed USB 3.0 3-Port Hub (VIA VL810 Chipset, 5V/2A Power Adapter, 3 feet USB 3.0 Cable)
Pros: Combines an external multi-card reader and a powered USB 3.0 hub.
Works perfectly with my Win7 64-bit PC with its AM3+ motherboard's onboard Eton USB 3.0 chipset.
When traveling, I have found this hub to be an indispensable accessory to my Nexus 7 tablet, which has 32GB of internal storage, but no expansion card slot. So the only way I could utilize any external data was to root the device, and plug an OTG cable into its charging port. When practical (or necessary), I generally plug this hub into the OTG cable, rather than just a USB flash drive directly. If powered, the hub reduces battery drain on the tablet. Also, using the hub in this way, the tablet can "see" multiple external drives, and the tablet can simultaneously utilize an external USB mouse and/or keyboard - all connected via this hub. It all works wonderfully to overcome the Nexus' stock limitations.
The hub's ability, with my tablet, to enable multiple drive usage, can sometimes be really helpful. For example, HD video files sized 4GB+ can only exist on NTFS formatted drives. But NTSF drives are read-only to current Android devices. So to also be able to write, you need a 2nd external FAT32 formatted drive (or partition). With this hub, no problem combining different drive types (e.g. USB stick, HDD, SDHC card).
If this tablet/phone solution is of interest, note 2 things: (1) Speed will be limited to USB 2.0 specs (that's all current Android devices support). (2) Although the hub will power all attached USB devices, an Android device's internal battery won't charge through a simple OTG cable connection.
This device's card-reading ability is exceptional. I have an SDHC card that, after about a year's use, somehow got sufficiently damaged that numerous card-readers and cameras couldn't even recognize it on insertion. Only this device could. Using this device, I was able to reformat the card. But even after the reformat, other card readers still couldn't even recognize it. Yet through this HooToo device, I've been able to successfully use the damaged card as a Windows 7 installation media.
Cons: None, for me. I suspect that problems mentioned by other reviewers likely stem from use with older motherboard USB chipsets and/or drivers. Some early USB 3.0 implementations were pretty buggy.
Other Thoughts: It's very light, and can slip around. So for stable use in specific places, get some stick-on Velcro strips and attach to anchor.
If you do not need the card reader function, or if you specifically want to be able to charge Apple devices from a USB 3.0 hub, then newer devices are available, including from HooToo, which have more USB 3.0 ports, and may be more suitable.
Pros: Fast Shipping
Cons: Received DOA.
Bought New. Received open box (no cellophane. Cardboard flaps not even closed). No driver disc or "Free Bundle" enclosed. Probably somebody else's RMA.
Other Thoughts: $13.50 freight to return. What would anybody think?READ FULL REVIEW
