Pros: For CrystalDiskMark 4.0.3 x64 using RAID 0 Stripe size 64kb simple disk and 4C/8T CPU,
Sequential Read (Q= 32,T= 8) : 1123.047 MB/s
Sequential Write (Q= 32,T= 8) : 1039.057 MB/s
Random Read 4KiB (Q= 32,T= 8) : 628.678 MB/s [153485.8 IOPS]
Random Write 4KiB (Q= 32,T= 8) : 726.322 MB/s [177324.7 IOPS]
Sequential Read (T= 1) : 789.481 MB/s
Sequential Write (T= 1) : 882.920 MB/s
Random Read 4KiB (Q= 1,T= 1) : 24.917 MB/s [ 6083.3 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 108.103 MB/s [ 26392.3 IOPS]
Test : 500 MiB [C: 44.8% (199.7/446.2 GiB)] (x3); OS : Windows 8.1 [6.3 Build 9600] (x64)
Only 4k random write at qd1 is slower than non-RAID by roughly one third. Most of the other numbers are significantly higher, one of which hit the RAID 0 ceiling of 12G. This is significant improvement over non-RAID and thus not a bad compromise at all in terms of real life performance. However the NVME drives do not have any compromises. Other pros include Ultrabook compatibility, 3.5" adapter, good warranty and Acronis cloning software.
Cons: Does not support BitLocker encryption as expected due to extremely slow encryption speed. However some third party encryption utility probably have on the fly encryption. The drives did not come with latest firmware. The drives are slightly slower than Vector 180 which is slightly slower than the fastest SATA SSD. None of these drives support BitLocker. The firmware update process is not the most advanced as it requires a complete power cycle, which can be hard to follow through for some people as seen on the forums. OCZ SSD utility does not recognize these drives at all when RAID 0 is used. Also, this utility is very limited in terms of capabilities.
Other Thoughts: Using RAID involves tweaking the bios, loading the Intel RAID driver during Windows installation and possibly using DiskPart. I installed the latest SSD firmware, bios firmware and RAID driver before I did anything. Vertex 460A is more like a lower tier transition drive because the BF 3 controller runs at lower speed while using latest 2nd generation NAND. Based on experience despite what you read on the reviews, the rated speed in the specs are fair indicators of expected performance especially comparing to other similar drives. The drive probably will still have 100% SMART status after more usage, which is expected.READ FULL REVIEW
Pros: Via local Ethernet connection, the video files transfer at around 100 MB/s while the pictures transfer at 1 MB/s. All files are easily uploaded via the MyCloud feature in WD QuickView located at the taskbar. The firmware upgrade notification appeared on my mobile app at the beginning and it seemed like it can initiate the firmware upgrade. The mobile photo app easily works as intended once you have photos uploaded. The NAS appears to run off of firmware via software utility and browser interface instead of custom Linux OS. WD SmartWare is for backup purposes while WD MyCloud is essentially a file explorer. No Install CD/DVD was included nor needed, which is fine these days. Setting up the NAS physically was easy. I recommend that for easy setup and use in export controlled environment, everything should be done through WD settings interface via web interface.
When it comes to the physical WD Red HDD’s and NAS performance, there are already many reviews with benchmarks everywhere on the web for you to analyze. The two 4TB drives are in what appears to be in RAID 1 by default. The info panel at the front of the NAS is very useful. It gives you basic temperature, fan, IP address, capacity, SMART and firmware information. Like most systems with HDD, the drives enter sleep mode when not using. Both of the HDD’s run simultaneously as they would in RAID 1. You also can change the RAID level. I wasn’t sure whether the firmware update was for the NAS or only the HDD’s themselves. The NAS enters standby/sleep mode when I tried to shut it down to take it apart. You have to hold down the power button for full shutdown. I was able to pull up Crystal Disk and AIDA64: The HDD supports SMART, NCQ and is 5400RPM, 6G and formatted in AF GPT. The outer cover of the NAS can be easily taken off, but not the front panel. Therefore it is difficult to take out the main board. However this has already been done for you in one of the reviews on the internet. Battery backup requires the IP address of the networked UPS master. All HDD utilities are included and self-sufficient in the NAS as you would normally find in Windows. NAS runs at about 35C and has a 140mm back fan that runs slowly at 645 RPM, which is still audible. The HDD’s are full sized 3.5” drives, not slim. No user manual was included.
Cons: Setting up for installation wasn’t very smooth because WD NAS software is not fully compatible with Windows 8.1. However, I got past that via some tweaking and made all apps work. HDD’s slide in and out easily and there is no locking mechanism, which could be a security issue. There is no Built-in anti-virus nor surveillance package. Booting up the NAS takes a while.
Other Thoughts: Price not justified with the specified cons.READ FULL REVIEW
This review is from: Linksys AC1900 Dual Band SMART Wi-Fi Gigabit Router (EA6900)
Pros: Easy to setup using the wizard, but you can also choose to do it manually. Great for using it only as wireless router, not access point nor media bridge. Very useful and easy to use information is found within the browser interface. Very user friendly design; easy to mount on the wall and easy to work with psychically. Tolerates downstream Ethernet routers as access points and still keeps the integrity of both wired and wireless SSID for all networking devices.
Cons: default guest password is easy to crack, I recommend changing it asap. Other people might eavesdrop over the guest network according to Windows.
No easy way to use it as access point nor media bridge/extender (in the sense of only clicking a button).
When everything was setup there were ping issues with wireless, but next day this problem resolved by using wired Ethernet. Linksys doesn't seem to care to provide updated firmware. This only means possible security vulnerabilities. Price is not justified with those many negative reviews on wireless connection drops on the duplicate product listing on Newegg. Antennas are not extendable; they are what they are. Only a simple Quick Start guide was included, which was largely only good for bookkeeping. The user manual wasn't very useful and is very vague with numerous excuses like "see above instructions... setting this up as an extender is a complex process."
Other Thoughts: I don't know why there were too many sub-par reviews, but at least own this device before you write any reviews. This device is not what you think it is. The router uses a custom OS, not Linux. The connectivity and security settings are the most involved and requires a bit of basic networking knowledge. Most of those settings could be left as default.READ FULL REVIEW
