Pros: Very competitive price from one of the world's top memory supply companies.
Tested in my Lenovo, Asus, Acer, Dell.
Compatible with low voltage 1.35 - important for laptops.
Easiest ways to improve laptop performance is more memory and an SSD.
Other Thoughts: THE COMPANY:
Silicon-Power Computer and Communications Inc. is one of the largest global memory suppliers and is headquartered in Taiwan. They are very big in the Japan, China, New Zealand, and Australia markets. I have used a lot of their product.
A bit about LATENCY and SPEED since it is mentioned in the specs:
CAS latency (CL) is how many clock cycles the data must go through. This is not an accurate indicator of real word performance. True Latency (in nanoseconds) is the best measure and is equal to (Clock Cycle Time) x (Number of Clock Cycles). So for typical DDR3 memory modules:
Module Speed (MT/s) CAS Latency (CL) ClockCycle time(ns) True Latency(ns)
1333 9 1.50 13.50
1600 11 1.25 13.75
This review is from: Silicon Power 64GB Blaze B05 USB 3.0 Flash Drive (SP064GBUF3B05V1D)
Pros: BOTTOM LINE: Very competitive price on a mid-range performance USB 3.0 stick from one of the world’s top memory supply companies.
Over twice the speed of a 64 GB USB 2.0 stick.
About .25 cents per GB.
There are faster sticks out there but they cost more.
Sequential read speed is about 130 MB/s. Sequential write is about 69 MB/s.
Retractable, so no cap to lose. LED.
Cons: Average performance for a 3.0 USB stick which is offset by the price. Plastic case.
Other Thoughts: THE COMPANY:
With the large amount of counterfeit USB sticks out there, I get suspicious of any unfamiliar brand name if the seller is not Newegg. Silicon-Power Computer and Communications Inc. is one of the largest global memory suppliers and is headquartered in Taiwan. They are very big in the Japan, China, New Zealand, and Australia markets. I have used a lot of their product.
The NAND flash market supply is high and growing which is why prices on these things are falling compared to the DRAM market.
I tested the speed of this stick using Crystal Disk Mark and ATTO to get the numbers - which put it the average speed range for 3.0 sticks. If you are like most people who use USB sticks -- writing much less often than reading from them -- the write speed won’t matter as much to you as the price. Read speed is comparable to a typical consumer hard drive. Write speed is about half of that.
With NAND pricing so low, the case is probably a significant component of the price. Expect to spend 10-20% more for a more premium (metal) case.
This review is from: NETGEAR R7800 Nighthawk X4S AC2600 Smart WiFi MU-MIMO Gigabit Router
Pros: Understanding the ins and outs of the newest Wi-Fi technology is getting more difficult as technology matures. The good news is that more 2-stream MU-MIMO portable client devices are coming out (for example, the Nexus 5X, the Zenphone 2 Selfie, many of the Acer Aspire laptops, MSI GT72 Dominator, Dell Alienware 13).
BOTTOM LINE: this is the ultimate, absolute best, pinnacle of MU-MIMO routers currently available. It is the first product on the market to support 160 MHz bandwidth mode. Does this matter to you? If you don’t know keep reading.
HARDWARE: Qualcomm-based. Latest generation QCA9984 4x4 MU-MIMO 802.11ac radio. First-ever router to support 160 MHz bandwidth mode. 512 MB RAM and 128 MB flash memory. IPQ8065 Internet 1.7 GHz processor. Two USB 3.0 ports. Single eSATA port. Physical Wi-Fi On/Off button on top. Gigabit ethernet ports x4 with individual LEDs. Large heatsink plate inside so should last a long time.
SOFTWARE: standard NETGEAR genie interface supporting: AP & Wireless Bridge modes, QoS, remote access to settings. OPENVPN. I tested Wireless bridge mode with a non-Netgear 4 stream router and it worked. Imagine simultaneous up/down THROUGHPUT of well over 900 Mbps across the house without running wire!
NAS & REMOTE ACCESS FEATURES ARE BIG: The router enables many NAS and remote access features. For connected storage: NTFS USB3.0 Read/Write is about 90/56 MB/s. If your needs are relatively modest you might not need to get a separate NAS for home.
Free Netgear DDNS service via NoIP.
You can share storage locally using ReadySHARE. For remote access, it supports ReadyCLOUD which is Netgear’s secure remote access to their NAS products and upper level router-connected storage. It supports desktop/android/iOS clients. Access your network remotely using OpenVPN. Premade client makes this ordinarily complex process a lot easier. DLNA media server and MyMedia feature finds photos, videos, and music anywhere on your network. The Kwilt android/iOS app is supported to organize and share photos. FTP is supported. Printer sharing supported.
PERFORMANCE: The regular stuff => Routing - WAN to LAN 765 Mbps. LAN to WAN 780 Mbps!! Avg 2.4 GHz Up/Dn Throughput 95/125 Mbps. Avg U/D 5 GHz Throughput 230/210Mbps.
The crazy new stuff => first product on the market to support 160 MHz bandwidth mode (implemented as 80MHz + 80 MHz). I am unable to test it because there are no clients that support this yet. Theoretically, this should double the maximum link rate to 1733 Mbps vs 867Mbps.
MU-MIMO benefit is also a bit hard to test because so few client devices support it. Go to qualcomm.com/products/vive/devices for the latest list. I only had three 1x clients available. Arranging them sort of equidistantly around the router I found a major improvement in total download throughput between MU-MIMO on-vs.-off (over double). Couldn’t test more than 3 clients myself. Smallnetbuilder.com - using a special test setup - found this router to have best MU improvement of all MU compatible routers particularly when using many client devices.
Cons: none, except to note that part of the features you are paying for are for future-proofing. They are so cutting edge that few client devices exist yet to take full advantage of them. Current chipset only supports 3 simultaneous clients per single MU-MIMO transmission.
Other Thoughts: Strategies for increasing throughput to just one client device are the same for 2.4 GHz and 5.0 GHz -> Increase the number of “streams”. Each stream gets its own antenna. The “4x4” designation for this router means it can transmit on 4 antennas and receive on 4 antennas. Using N-only protocol on 2.4 GHz usually gets you a maximum of 150 Mbs per stream/antenna. On this router you get potentially a little bit more (800 Mbs with four antennas) because is uses 256-QAM. Ac-only mode on 5 GHz gets you a maximum of about 433 Mbs per stream/antenna which works out to 1733 Mbs on this router. Add that to the 800 on 2.4 GHz, round up, and you get “AC2600” -> the designation of this router.
The problems are: 1) not every peripheral device has 4 antennas (most portable devices only have one per band - some newer ones have two), 2) multiple devices often need to connect at the same time, 3) data THROUGHPUT is always lower than bandwidth speed (LINK RATE) due to protocol overhead - often by about 50%.
A solution to some of these problems that affect total throughput is “MU-MIMO” which uses advanced beamforming to enable simultaneous AP-to-client transmission on the same channel rather than round-robin mode where the AP takes turns talking to each client. This simultaneous transmission happens for downlink traffic only. This router’s chip can do three simultaneous client transmissions at a time even though it has 4 antennas and the 802.11ac standard allows for up to 4 simultaneous clients.
The catch is MU-MIMO only works with MU-MIMO enabled clients and works best when those clients are stationary in relation to the router. MU-MIMO enabled phones, tablets, and laptops only started becoming available somewhere around July, 2015. I count only 7 consumer routers that have the technology (I have three based on the prior generation chip - QCA0080). This new one does MU best.
If you need a new router now, buy this one to future-proof the newer wifi devices. Residential internet download speeds are getting faster than the WAN-LAN speed of older routers. The two reasons I had to replace my last consumer router with a custom-built PfSense computer was WAN->LAN speed and my need for OpenVPN to run smoothly. This router’s hardware is fast enough to replace my PfSense box at a fraction of the cost while this router’s stock firmware gets me OpenVPN unlike some of its competition.
