How to Install iStarUSA BPU-350HD
To ensure a secure and reliable installation, follow these steps. Note that a compatible RAID controller is required to enable RAID configurations; the enclosure does not include a built-in RAID controller.
- Power down your computer or server and unplug it from the power source. Open the chassis to access the internal bays.
- If you plan to use RAID, install a compatible RAID controller card into an available PCIe slot on the motherboard or in your server. Ensure the controller firmware is up to date and compatible with your drives.
- Mount the BPU-350HD into an available 5.25" front bay, securing the enclosure to the chassis with screws according to your case’s guidelines.
- Connect SATA data cables from the RAID controller or motherboard to the backplane of the BPU-350HD. Insert each HDD/SSD into the hot-swap rack and secure them as needed, ensuring proper seating in the drive bays.
- Connect the appropriate SATA power supply lines to the enclosure if required by your system configuration. Power up the host system and enter the RAID controller utility to initialize and configure the drives as desired (RAID level, stripe size, etc.).
- Power on the system and monitor the LED indicators on the enclosure. Confirm that all drives are detected and that cooling fans operate correctly. Test a data transfer to verify performance and reliability.
Frequently asked questions
- Is RAID supported with the BPU-350HD? RAID configuration is supported via an external or host-side RAID controller. The enclosure provides hot-swap backplanes and drive connectivity, but the RAID functionality must be managed by a separate controller.
- What drives are compatible? The backplane accepts 3.5" and 2.5" SATA HDDs and SSDs, allowing a mix of drive types within the same enclosure when used with the appropriate controller and cabling.
- Is the unit hot-swappable? Yes. The design supports hot-swapping enabled by the backplane, enabling drive removal and replacement without powering down the entire system, provided a compatible RAID/controller setup is in place.
- Does it come with a RAID controller? No. A separate RAID controller is required to configure RAID arrays and manage redundancy and performance across the installed drives.
- What is the form factor? The enclosure is designed for a 5.25" drive bay in the front of a chassis and provides internal SATA connectivity to support drives configured through a RAID controller.

Absolute game changer for chronically dry feet/cracked heels
Size: S (up to size 7)-Beige
I had recently bought a pair of silicone heel/ankle wraps to fill out my boot a little since I noticed my heels were lifting when I was skating. I tested them out around the house and noticed they left my heels softer while the rest of my sockless feet got quite dry. So I got these full foot silicone socks to see the effect of having my whole foot covered. I slather the entirety of my feet with Dr. Scholl's Severe Cracked Heel Restoring Balm (love how convenient it is to apply it to my feet with the solid stick form) and then slip them into these silicone socks. After just a couple hours, when I pull out my feet they're (a teeny bit sweaty at first), but then overall soft and smooth and have absorbed the balm fully leaving barely any residue in the silicone sock. I find these silicone socks generally comfortable; I wear them in the evenings while relaxing on the couch, take them off after a couple hours and let my feet breathe a bit, and then reapply my balm and socks and wear them to bed. If I wake up in the middle of the night, which I almost always do (not because of the socks), I'll take the socks off and allow my feet to breathe again. I wear a woman's size 6 shoe and the small size is pretty comfortable. However, I made the mistake of wearing them while being on my feet for a couple hours straight during household chores -- they must've somehow cut off my circulation a bit with the standing, so I wouldn't recommend wearing these silicone socks while being active. And since they're not exactly my foot size, they slide around sometimes and will start to feel tight at my big toe. But if that happens, I just tug on the toe area of the sock to give my big toe more wiggle room and problem solved. Prior to wearing these socks, I was soaking and doing heavy duty exfoliation of my feet every week. These socks seem like they'll work to help me extend the time between soakings and exfoliations. The 5 pack is a great value. So far none have torn, so they seem rather durable. Not sure what I could even do to tear a hole in these.

EXCELLENT FEET MOISTURE PROTECTION
Size: S (up to size 7)-Beige, Size: S (up to size 7)-Beige
Why did you pick this product vs others?:
I have burns on my feet and needed something that I could put burn creme on and still walk around in with. I tried other silicone footsie but they would teae really easily. So far these are doing really well for this purpose. They are holding their shape too. The only caution I have is the same with all silicone footsies: They can be slippery on wet floors, so also wear with socks over them.
The biggest issues is when they say a size they mean it. The silicone used in these have little give in them, so they won't stretch out and loose their shape. That can be a good thing, or not so good, depending on how well they fit your feet and what your intent is with wearing these. The other issue is if they fit snug around those toes, that tends to be where the first tear in the material will happen. Because of how these are made, the tear is actually more like cracking in the material and once it occurs you won't be able to get much use out of the sock after that. If you are planning to wear them around the house or for long term use, I suggest going up a size or look for the toeless options.

Silicone socks
Size: M (up to size 9)-Beige
The socks are sized large. The quality of the silicone is good. But they slide around on your feet if you try to walk, making them difficult to use and a bit uncomfortable. Unless you are able to sit for long periods of time the likely will not work well. Recommend looking for a better value.
