Pros: I ran out of SATA ports on a large video recorder box, and got this to add more drives. So, far it works very well. Historically I have not been a Marvell fan, but this 88SE9230 SATA chip seems rock solid, and handles concurrent SATA-II 6Gbs traffic with ease. Supports port-multiplier protocol as long as you install the Marvell drivers. The default Microsoft Win7 AHCI SATA driver works well but disables port-multiplier support. If you aren't using RAID, just use this card as a generic 4-port SATA-III card. It works great for that. I have not tested SSD Hybrid HyperDuo mode [yet]

Cons: Disk arrays on external port-multiplier channels can not use Marvell RAID-0, or RAID-1, or RAID-10. It could if they wanted to -- with SATA-III speeds supporting multiple disks on one channel does not impose a speed penalty when compared to the physical disk performance. If you want RAID you have to use Windows 7 software RAID-0 or RAID-1, which actually works well and is plenty fast. That also insures raid sets can be read on Windows even if not currently plugged into a Marvell card. That's reassuring for disaster recovery if the card dies. No RAID-5, but I don't miss it.

Overall Review: This card is identical to a Rosewill RC-230, which Newegg currently sells for more money. Both use the same Marvell reference design and Marvell 88SE9230 drivers. Sadly, Marvell makes the OEM do the driver distribution and Vantec is behind on their web updates. I used the newer Marvell drivers found on the Rosewill site.

Pros: - This Pioneer Blu-ray drive is fine and does just what you would expect. Note, however, I have not tried writing data to a BD disc, nor do I ever expect to. I gave up on writing data to optical drives years ago.

Cons: - None for the hardware - The Cyberlink PowerDVD 14 software bundled with this drive can read and play DVD's and low-res BD's. However, to play a 4K Ultra HD disc you MUST have a system that supports Intel SGX processor extensions. I was planning to use this on an AMD system but it simply refuses to run (4K, that is). Grrr... Pioneer does not seem to mention this anywhere at all on their website. Cyberlink does mention it but you have to really dig for it by locating and downloading the manual for this obsolete version 14. Sadly, their current version 19 apparently has the same limitation.

Overall Review: - The Pioneer drive gets 5 stars - The Cyberlink software gets 2 stars I regret my purchase. This is no better for me than the older ASUS BD drive I was replacing. If you have an Intel system it (Ultra HD 4K playback) might work okay for you.

Cons: As is typical with USB connected mass storage devices, the USB controller hides many of the SSD characteristics so SSD support utilities like Samsung Magician do not recognize your SSD as one of their own models. So, no SSD firmware checking or upgrading over USB.

Overall Review: I posted this info for others who may be wondering about the hardware. I bought a couple of these Plugable devices from Newegg a couple years ago (2019). At that time they used a JMicron JMS583 controller. I just (2022) bought one of these newer versions and it uses a Realtek RTL9210 controller. In my opinion that's an improvement. The old and new devices look identical.

Pros: - Works okay as a standalone M.2 NVMe copier. I'm getting about 16 minutes per TB

Cons: - Yes, it runs pretty warm. Just be careful. - Yes, a 2280 M.2 sticks up pretty high. Just be careful. Don't hit one by accident. That would put lot of leverage on a delicate M.2 socket. When plugged into USB you'll want a longer cord than the short one they supply so it fits comfortably on your desktop and not hanging from the PC case. - Due to the case design, it will not take my Samsung 980 SSD's with the factory heatsink. The non-heatsink 980 version works okay. I don't feel like removing the factory heatsink since it will tear up the thermal pad. I hate to grind the corner off my SSD just so it will seat into the M.2 socket.

Overall Review: - They could modify the case to provide more room around the M.2 sockets. I might try it myself when I get time but that will require some metal work. - They could improve the internal shielding around the blue LED's. During copying when one LED flickers they all seem to flicker, - For the curious, mine is using an ASMedia ASM2362 NVME-to-USB chipset. Sadly, that hides the true drive characteristics so you can't run most SSD utilities like Samsung Magician or Crucial Storage Executive and have them recognize their own brand/model SSD's. - When using USB, even if the blue power LED lights up, it might not have enough power for your SSD to read and write data. Be sure to use the external power brick for adequate current. - Windows is often slow to recognize new disks. You might need to reboot to see them. - This is a model M03 from Acasis.com On their web site they have an English user guide you can download. The unit itself had no English instructions.

Pros: I'm using mine not as a Wi-Fi to Wi-Fi repeater, but as an Ethernet to Wi-Fi Access Point. - Simple, easy setup - Reliable, stable, performance with good Wi-Fi coverage around my entire house. I was able to eliminate a Wi-Fi repeater in my upstairs hallway because this RE9000 in my downstairs living room puts out such a strong, stable signal. Our phones, tablets, and Echo devices are much happier now. - No confusing screens for disabling WAN ports, etc, like you get with a router/Wi-Fi device configured as an Access Point - Easy to place up high for good RF transmission, rather than being stuck on the floor or behind a cabinet. - Puts out a single 2.4GHz SSID, but also (optionally) puts out one or two 5GHz SSIDS on separate channels. They can be different names. I'm using one as a dedicated back-haul link to a distant Wi-Fi repeater in my garage. - Able to select channel bandwidth. Some of my older IP cameras could not negotiate 40MHz-wide channels properly, but the RE9000 let me lock them down to 20MHz.

Cons: Linksys, if you're watching, next time you update the firmware please improve the Wireless Clients Table page so the Clients Name column is wider. It cuts off long names. Also, if I save may own descriptive name for a MAC device, it wants me to have a name for each and every item on the page. That's not realistic. I have a similar problem on RE7000 repeaters. It would be nice to be able to import or export a list of known MAC devices with their names.

Overall Review: I have a strong dislike for "Swiss Army Knife" devices that put all their functions in one box. It's a mystery to me why people still by all-in-one combination modem/router/Wi-Fi boxes, then have configuration and performance problems. I much prefer separate devices, especially WI-Fi access points. I used to take router/Wi-Fi boxes and treat them as a Wi-Fi access points by running Ethernet from my primary router into one of the LAN ports on the Wi-Fi device. That usually works but there are often complications like needing to use the WAN port for firmware upgrades. So, I now prefer dedicated Wi-Fi access point devices like this RE9000 I bought my first RE9000 about a year ago and have been very happy with it. Just this week a bought a second one for a friend who was getting terrible Wi-Fi performance out of his DSLmodem/router/Wi-Fi box.

Pros: - Cheap! - Does a pretty good job considering the price - The LED lights really help. I'm glad they are adjustable.

Cons: - The suction cup mount with the flex arm works okay, but is not very rigid. You will bump it when you turn the focus ring. There is no electronic focus. You don't need the flex arm if you just place the camera on top of something flat for up-close viewing.

Overall Review: On Windows 10, USB video drivers from Microsoft install automatically. Also, the Windows 10 'Camera' app works fine with this microscope. The 'Digital Viewer' app from Plugable works, too, but is nothing great. The DV app gets confused by the presence my Logitech USB webcam but it still works. I just have to select the wrong camera! Both apps can take snapshots or video clips. Windows also installs audio drivers because it thinks this is a webcam but they don't really do anything. I use mine with Windows, but I also tried it with my Android 7 tablet and my Android 9 phone. I went to the Google Play Store and searched for "USB camera". The first app I tried works fine. Magnification is related to how far the camera is from the subject. Rather than constantly bending the flex arm, it's easier to use a book (or something similar) under the object you're viewing to raise it closer to the camera.
