This review is from: CORSAIR Voyager Slider 64GB USB 3.0 Flash Drive Model CMFSL3B-64GB
Pros: This was actually a rough review for me to do, not something I expected from something as simple as a flash drive. This is going to be a pretty long review for a flash drive.
First, lets get the pros out of the way.
- Great USB 3.0 read speeds.
- Faster than USB 2.0 write speeds.
- Great USB 2.0 performance.
- Activity light indicates USB 2.0/3.0. (Flash speed)
- Slider is convenient. No cover to lose.
Here are the drives specs based on CrystalDiskMark 64-bit. Listing the best speeds achieved after multiple tests. The important numbers are the Sequential Reads/Writes.

On USB 3.0, it takes about 4 minutes to transfer a single 3.9GB uncompressed Fraps video file to the drive. With it's transfer speed settling at around 16.5 MB/s to 17 MB/s.
To read that same file it's transfer speed topped out at about 75 MB/s. Much faster.
The averages for bulk transfers of smaller files, such as music, were only slightly slower. Writes ranged from about 15 MB/s to 15.5 MB/s.
For the sake of comparison, here are some numbers from a couple USB 2.0 drive I have on hand. The fastest being a Patriot XT , and a slower "standard" 2.0 drive, also made by Patriot.
USB 2.0 50MB MB/s: XT

So there you have all the numbers I got from my testing. This Corsair Slider Flash Voyager USB 3.0 is clearly faster than any USB 2.0 drives I have, especailly in the reads where it's vastly faster. Now on to the "tough" part of the review.
Cons: Slower than expected USB 3.0 write speeds. (See other thoughts)
You have to hold the slider open when inserting the drive into most USB ports, or it will close on you. Just hold your finger on the back of the drive and you're fine.
Other Thoughts: In the cons, I list slower than expected USB 3. 0 write speeds, and that's what made this review a bit tougher than I expected for a simple USB flash drive.
When I review an item, one of the things I do is look at other people reviews to see if I have any of the same results, problems, or other similarities. I also look at benchmarks on trusted sites if they are available. Depending on what I learn, I may gear some of my testing, or do extra testing, to target specifics of other peoples results, good or bad.
In this case, it was the USB 3.0 write speeds.
You have a lot of reviews saying they had poor write speeds compared to other drives, and much lower than advertized by Corsair. I noticed my numbers were roughly the same on the writes as many of the people were listing in the review. So I decided to try and find out why.
As far as the advertized speeds go, at the time of this review, I can find no "official" listings of this specific drives speeds. No on Corsair's product page, and not here on the Newegg product page. However I can find benchmarks that show the drive getting much better write performance than I am getting.
After a bit more searching, I came across a forum thread on Corsair's website that claims there were two versions of this drive, the older CMFSL3, and this one, the CMFSL3B. According to the thread, the CMFSL3 had "been discontinued because of the availability of the the components. CMFSL3B-32GB is the replacement for it and it is slower then the first gen. "
I have no way of knowing if this is correct or not, I did email Corsair to ask, but I have limited time to do this review, so I can't wait for a response. However it would explain the slower speeds than seen on older models of this drive.
If this information is correct, it would be nice to see it officially listed somewhere.
So what makes it tough is how do I rate the drive? While I am not able to hit the speeds seen on what may be older versions of this drive, I have to base my review on how this version of the drive performs today, based on how it's advertized. Like I said above, there are no official speeds listed on Corsair's product page, or here on Newegg.
This is why I gave the drive a 5 Egg rating. It is faster than USB 2.0, and it gave me no problems what so ever during my testing. Based on that I can say that it's a solid USB 3.0 flash drive, and while there may be faster options out there, this drive worked well for me.
I will do a followup review later if anything changes or the drive gives me any problems, since I see some people saying the drive failed after 4-6 months. As of today however, the drive is working wonderfully.
Tested on two different systems.
ASUS Sabertooth 990FX R2.0
Windows 7 Ultimate 64
ASRock Z97 Killer
Windows 7 Ultimate 64
This review is from: FREMO P100 10400mAh Power Bank Charger & Dual Port USB Car Charger for iPhone, iPad, Galaxy S5, Note, Galaxy Tab, Nexus, HTC One, One 2 (M8), PS Vita and other Smartphone and Tablet (made by SCUD)
Pros: - Solid build quality
- Included car charger
- Great charging/powering performance
When I say great charging and powering performance, I mean that it does what it says it can, and it does it well. It works fantastic and as intended when it comes to charging and powering cell phones and tablets. Easily hitting the target charge numbers they have listed in the product description. Getting 2 or more full charges on high drain devices, and 6 more on lower drain devices. It all depends on the device, how low the battery is, and if it's being used during charging.
Great for trips or whenever you don't expect to be near an outlet for long periods of time, when all the other outlets are in use, or when there simply is no power available. Such as camping, hiking, or during a power outage.
However, it also works great for most any portable USB powered device. Beyond the cell phones and tablets I tested the unit on (see Other thoughts), I also used it to charge/power a portable handheld game system. I even went a bit overboard and used it to power a portable nano router to use as a temporary "hot spot". Just to see if it would work, and it did, for the just under 2 hours under load that I tested it.
The included 2 port USB car charger is great to have. It works wonderfully and can help maintain the power bank or power/charge other devices on long road trips.
Overall, I was really pleased at how well the unit worked and would easily recommend it to anyone looking for such a device. In fact, some of my friends and family that helped he test it now want one.
Cons: Not enough to knock off any Eggs in my opinion, but a few things worth mentioning.
- It does take several hours to charge the device (4-8 hours depending on how far down it's depleted), but considering how well it charges and powers the devices you plug into it, it balances out.
- It does "trickle charge". If you leave it plugged into a device, it will keep charging the device, maintaining 100% charge on it. I list this as a con since some people will not like that, others will, either way it should be known.
- The aluminum housing is very sturdy, but the edges are somewhat sharp. I don't mean sharp as in cutting anything, but if you happen to store it in the same space as your phone or tablet, and the screen is not protected, there is a chance it could scratch the screen if it gets jostled around a lot.
No different than keeping your phone in your pocket or purse with your keys or other metal objects. If you have a screen protector and/or case on your phone or tablet, you should be just fine. Something to keep in mind.
- The included USB cables used for charging the device off your PC or laptop is very short, just under 9.5 inches (about 24cm) from the end of one plug to the other, giving you just over 8.5 inches (about 22cm) of effective cable length.
Other Thoughts: Items used/tested with this power bank:
Samsung Galaxy Tab 2
Samsung Galaxy Tab 3
ASUS Memo Pad 7 HD
Samsung Galaxy S4
AT Games Sega Genesis Portable
TP-Link 150Mbps Nano Router
As I said above, this FREMO P100 Power Bank from SCUD works as advertized, and would make a great companion to any traveler, in an emergency kit, or anyone who always seems to be running around with a dead phone or tablet.
Pros: This Z97 Killer Fatal1ty board from ASRock makes a great backbone to any single GPU based gaming build. It's low price point, rich feature set, and nice build quality make it a great choice for those looking to build a powerful gaming system, but don't want to blow the budget on the motherboard.
Just becasue this is a low cost board, does not in any way mean it's "cheap". The board still features the Killer E2200 NIC, Purity Sound 2, an M.2 Socket, and a host of other high quality components that add greatly to the boards robustness and value.
It's has a couple features I like to see on a motherboard. Such as plenty of fan connectors, including 2 for the CPU. This is great for push/pull or closed loop water cooling options. M.2 card support up to 110mm, this is nice to see even on a less expensive board.
The board is also aesthetically pleasing with the red and black color scheme and nice large heatsinks.
Having all the SATA connectors in the lower right/back of the board is also nice to see, keeping them out of the way of the primary PCIe expansion slots.
The Killer E2200 NIC is nice to have, as it gives you a great deal of control over your network and traffic options. When it comes to actual gameplay, on modern high-end hardware, I really don't see any gameplay or latency differences between it and a quality NIC. Still, I enjoy the Killer NIC just for the level of control it offers.
Cons: None really, but a couple things to point out.
The board only has a single PCIe 3.0 X16 lane and a secondary 2.0 X4 lane. This is why the board has no SLI support, only Crossfire. This would only be a hindrance if you plan on running a dual-GPU setup. However, a single dual-GPU card would still work.
One of the 4-pin fan headers is (chassis) is wedged right in with the 6 SATA headers, which are split into two banks, one of 4 header, the other six, with the 4-pin fan and SATA Express headers in between.
The board does have a few standard (not solid cap) capacitors. However I don't anticipate these being an issue. Just an FYI.
Other Thoughts: For the purposes of testing the board out, I paired it with an i5-4670K and my Sapphire R9 290 Tri-X OC. As well as 16GB of A-Data DDR3 1866 RAM. I then proceeded to get in some stress testing and gaming under Windows 7 Ultimate 64.
There were no problems running the RAM at it's rated speed, or overclocking the CPU. I was easily able to hit 4.4GHz without any voltage adjustments, and my target of 4.5GHz with a slight voltage bump. I know this chip to be stable up to 4.6GHz at 1.26V based on overclocking it on other boards. I ran it at 4.5GHz for the entire time, the same clock I run it at in it's home system. This seems to be a common sweet spot for these chips.
For the purposes of testing, I played several different games and ran some hardware benchmarks to see if I ran into any issues. All of the hardware I used on this board was pulled from a tested, working, stable system to try and eliminate it as a problem source, should there be any.
I used this system, backed by this board, for the past 5 days. Always on.
For the gaming, I played games like Diablo III, Battlefield 4, BF Hardline Beta, Crysis 3, and DayZ. In each and every case, the games played fantastically and as expected based on the hardware. No stability issues or performance problems what so ever.
For the sake of stress testing via benchmarks, I ran several of them for quite a long time overall. Star Swarm, Furmark, 3DMark, PCMark 8, AIDA64 Stability Test, AIDA64 Cache and Memory Benchmark, and CrystalDiskMark. In every case, again, no problems what so ever. The system was perfectly stable.
All in all this ASRock Z97 Killer board is a fantastic deal for anyone looking for an inexpensive board to build a powerful single GPU gaming system around. It's got a lot a high-end features at a nice low price point. I would, and will, easily recommend it.
Now that I have returned all of the hardware I used to test this board back to it's system. I am going to use this board in a new mid-range gaming build based around the new Intel Haswell Pentium G3258 Anniversary Edition Unlocked dual-core processor and see how far I can push it on this board. Since it would be a perfect companion to a board like this for someone looking for a low-cost mid-range gaming build on a budget. As well as giving them a great upgrade path should they choose.
Once that day comes, I will do a full followup review.
