This review is from: Raidmax RX-AU324 3.5" Internal 2-port USB3.0 and 2-port USB 2.0 Hub
Pros: Functions if you do not plug in the power connection.
Cons: In response to Mark T.'s review: I can verify this behavior, and I know why it happens after investigating the issue. It appears my review never showed up, likely because I purchased from Fry's.
The electrical anomalies that cause the power LED to turn on etc. happen because the 4-pin power plug is electrically connected to the USB 2.0 port's 5v and ground pins. When the system is powered off, USB ports give standby power for wake-on-USB, and this product backfeeds that standby voltage into the entire system's 5v rail.
Even more worrisome is that something somewhere acts as a diode when the 5v rail has power but the 12v one does not. So both the 5v and 12v rails get about 5v of power. This undervolts but slightly powers everything in the system, from the USB port header. My motherboard fluctuates, pulling between 700mA and 1000mA from the USB header, which is enough to confuse my DVD drive and cause its motors to occasionally start, stutter and stop.
Needless to say, this is EXTREMELY BAD behavior, and recommendations to not use this product are well founded. Prolonged use is likely to cause damage to the hardware in your system.
Other Thoughts: I also contacted Raidmax and also received no reply.READ FULL REVIEW
Pros: Fast, while it worked.
Cons: Suddenly died for no apparent reason, just after 6 months. No hiccups or odd behavior, no blue screens or taking a long time to read a file. Worked fine yesterday, dead today.
Investigation reveals the BIOS can tell something is present and tries for 60 seconds or so to read the drive, then gives up and the SATA port it was plugged into reads no device present. Plugged into an external SATA enclosure, the light simply stays red.
Other Thoughts: While the system was running, I spot checked temps around the SSD under various load conditions and it was always cool to the touch.
I also had the pagefile remapped to spinning disks, to limit SSD writes.
PSU in the system is a Corsair running at maybe 60% its spec, tops. Seems to be in good shape, as are all other components.
Interestingly enough, since then the word "Enhanced" has appeared on the sticker, and the price has doubled from what's on my invoice. The manufacturer model number (MKNSSDCL60GB-DX) and the Newegg item number (N82E16820226151) have not changed, which is very odd. Industry standard is to add a revision number or at very least change the manufacturer part number if you make a change to the device, especially one that warrants doubling the price tag. This might mean the product has been updated, but the specs and the brand name of the controller have not changed, so I think it hasn't.
This review is from: Logitech M510 Wireless mouse - Black
Pros: Unified wireless. On/Off switch on the base. Internal storage for extra Unified dongle means you can grab it from your desktop and and have a mouse to use on your laptop on the go.
Side buttons and mouse wheel tilt actions are configurable. Other buttons are not.
Scroll wheel has nice action. There's a slight detent when it turns. (I hate when it spins freely with no action that you can feel.)
Buttons have nice action.
Cons: Tracking. It's absolutely terrible at tracking surfaces. I have three other (much older) Logitech laser mice to compare to. The other mice work on every surface I throw at them except for a black wood surface that has very rough wood grain. The M510 only works on one surface I've found so far, and that is a brown faux-leather cover for a pad of paper.
Surfaces the M510 cannot track on, but the V450, S520, and three other corded laser and optical mice track perfectly:
* The fabric arm of the couch.
* The pleather arm of another couch.
* The very slightly glossy granite table, only -barely- reflective, with lots of fine matte stone patterns underneath a very thin very subtle gloss.
It CAN track on:
* The thick, uncomfortable binder cover.
* Pant leg.
* A piece of paper. (But the paper moves. And if I have to duct-tape paper to my table to use my mouse, something's wrong!)
The biggest issue is the table, since the whole point of having the more expensive laser technology is to be able to use the mouse on the table without having to confine yourself to a mouse pad or other specific surface.
This is not the driver issue reported by some others. I searched after buying this mouse, and lots of people are reporting the same kind of problems. The M510's laser optics look different from all the other laser mice, so it looks like simply a bad design that looked good on paper but doesn't work in real life.
Also: Side buttons in games. If I assign them an in-game action, the settings screen reads the mouse event just fine and assigns it something that looks reasonable. But when I try to use the button in game, only one out of 10 tries actually causes the action to happen. For example, in Deus Ex: Human Revolution, if I assign one of the side buttons to "throw" and the other to "enter cover", I can press 'throw' seven times on average before he actually throws something. The same with 'cover'. Assigned to the middle mouse button or a keyboard key, the action happens immediately 100% of the time, on the first press.
Also: Resolution. If I turn the sensitivity up enough that my usual 2-inch range of mouse motion covers more than half the screen area, the mouse starts to skip over some pixels two at a time. I hate mouse acceleration, but the only way to be able to reliably be able to place the mouse at an exact pixel (e.g. for Photoshop) is to have acceleration enabled.
Also: Not a big fan of the texture of the rubber. It feels tacky, like it's already (after three weeks or so) starting to absorb oils.
Other Thoughts: The Unifying drivers seem to be able to configure other Logitech mice, even when they are not 'Unifying' mice. For example, the V450 shows up and for some reason has the middle mouse button configured to 'document flip' instead of middle mouse click. (Naturally, this can be set back, it just seemed interesting.)READ FULL REVIEW
