Discover the iStarUSA BPN-DE350HD, a rugged, trayless drive enclosure engineered to unlock flexible storage expansion in a compact 5.25" footprint. This high-performance rack converts three 5.25" bays into a hot-swap ecosystem for up to five 3.5" HDDs, making it ideal for workstations, archival systems, media studios, and compact servers. Built with an integrative aluminum design, it maximizes cooling efficiency and reliability while delivering rapid data transfer across SAS and SATA interfaces. The black anodized finish complements most chassis and cabinets, while the aluminum front bezel features a secure metal key lock to help safeguard critical drives in open environments. Whether you are building a budget-friendly storage server, upgrading a workstation for video editing, or expanding a NAS/ DAS setup, the BPN-DE350HD provides dependable, scalable storage with a streamlined, trayless operation.

  • Trayless design: Quickly swap drives without removable trays, converting 3x 5.25" bays into a hot-swap pool for up to 5x 3.5" HDDs, reducing maintenance time during large data transfers and routine upgrades.
  • Broad drive compatibility: Supports SAS I/II/III and SATA I/II/III hard drives, enabling mixed-drive configurations and future-proofing for evolving storage needs while maintaining solid performance.
  • High-efficiency cooling: Integrative aluminum chassis doubles as a heat sink, promoting efficient airflow across drives and minimizing thermal throttling during sustained workloads for longer drive life.
  • Security and ruggedness: Aluminum front bezel with a sturdy metal key lock provides physical security to deter tampering in shared or open environments, while maintaining easy access for authorized personnel.
  • Compact, robust build: Internal 12Gb/s capable backplane and heavy-duty aluminum frame deliver reliable, scalable storage expansion in a space-saving 5.25" form factor suitable for desktops, workstations, and compact server racks.

how to install iStarUSA BPN-DE350HD

  • Power down your host system and unplug all cables before installing the enclosure. Safety first ensures data integrity and prevents hardware damage.
  • Identify an available 5.25" bay in your desktop, workstation, or server chassis and remove any faceplates or blanking panels as needed.
  • Slide the BPN-DE350HD into the 5.25" bay, aligning the backplane connectors with the system’s internal SAS/SATA controller cables. Gently secure the unit with mounting screws if required.
  • Connect the internal SAS/SATA cables from your motherboard or RAID controller to the enclosure’s backplane ports. Ensure firm, clean connections to prevent intermittent drive detection.
  • Install your 3.5" drives into the 5x drive slots supported by the trayless design. The drives should seat firmly with no excess force; close the front bezel and lock using the included key.
  • Power on the system and enter your OS’s disk management utility to initialize and format the new drives as needed. Confirm that all 3.5" drives are detected and operating at expected speeds.
  • Configure any RAID or storage pool settings appropriate for your workflow (e.g., RAID 0 for performance, RAID 5/6 for redundancy, or JBOD for raw capacity).
  • Monitor drive temperatures and performance during the initial usage period. If temperatures rise excessively, improve airflow around the chassis or adjust fan settings if applicable.

Frequently asked questions

  • Q: Does the BPN-DE350HD support hot swapping? A: Yes. The trayless design is specifically built for hot-swapping drives, allowing you to replace or add 3.5" drives without powering down the system in many configurations. Always follow your host controller and OS guidance for safe hot-swapping.
  • Q: Which drives are compatible? A: The enclosure supports SAS I/II/III and SATA I/II/III hard drives. It is designed to accommodate 3.5" drives within the 5x bay configuration, enabling flexible mixed-drive setups.
  • Q: Is there a physical lock for security? A: Yes. The aluminum front bezel includes a metal key lock to deter tampering in shared environments and protect the drives when the system is unattended.
  • Q: What kind of performance can I expect? A: The enclosure uses a high-speed backplane with support for SAS/SATA interfaces at up to 12Gb/s, delivering fast data transfers across compatible controllers and drives. Actual throughput depends on the drives and host controller in use.
  • Q: Do I need any special cables or drivers? A: In most cases, no special drivers are required for basic drive detection. The device operates as a standard backplane back to the host controller. Ensure you have the appropriate SAS/SATA data and power connections for your system.

Almost perfect!
Color: With Coin Pocket - Forest Brown
I purchased this wallet primarily for its generous number of conveniently located slots and its coin pocket. If you can't fit everything you want to EDC in this wallet, you need to think about getting a sling bag! Having returned the same model in Grizzily Brown due to a stitching defect and ordered this one in Forest Brown, I can see it is a richer, lighter shade and the finish seems smoother and more refined. Some of my cards were tight in previous wallet slots, but everything fits great in this one. Why the one star off? First, this wallet is about a quarter inch too large in all dimensions, especially thickness. While it doesn't protrude out the top of my back pocket, it is a challenge to close the button on some pants and it is also snug side-to-side, so removal involves some wiggling until pockets stretch and the wallet breaks in. The leather used in its construction is smooth but stiff at first, given that it is about twice as thick as most American or European wallet leather I've owned: think bullhide. The smell is also a little off, definitely natural cowhide but processed with whatever is used to tan leather in India rather than in the United States. Finally, this looks like something that belongs in a pair of jeans or casual pants, NOT pulled out of a suit at a Michelin star restaurant. The stitching, evenness of dye and lines are far from perfect, but what it lacks in looks it more than makes up for in every day function, character, and anticipated durability.

The Best Wallet
Color: Boulder Black - Napa Smooth Black
This is the second wallet I have purchased from Bull Guard. The first one is identical and I have used it for approximately one year. The first wallet has held up perfectly. I just decided to buy a second one because I am so happy with the first one and I decided to break up my cards into frequently used in the second, new wallet and less frequently used in the first and older wallet. The capacity of the wallet is excellent. It easily holds all my credit cards, drivers license, bills, insurance ID cards, and my global entry card. The material, workmanship, durability, and quality is also excellent. The wallet is all leather and breaks in perfectly. The size is also perfect fitting perfectly in my rear pocket. For the price, this is the best man's wallet I have ever had and I highly recommend it.

Solid Wallet
Color: Wild Buffalo Grey
I recently purchased the ULL GUARD Buffalo Leather Wallet, and I’m genuinely impressed with its quality and craftsmanship. The buffalo leather feels durable and premium—this is a wallet that looks like it’ll stand the test of time. What I love about it: - Thoughtful Billfold Design: The bill compartment includes a separator, which is perfect for organizing cash and checks separately. It’s a small detail that makes a big difference. - Plenty of Storage: There are numerous credit card slots, making it easy to keep all your cards neatly arranged and accessible. - Clear ID Pocket: The transparent ID slot is a convenient touch, especially for quick access to your driver’s license or work badge. Overall, this wallet combines functionality with rugged style. If you're looking for something that’s both practical and built to last, the ULL GUARD Buffalo Leather Wallet is a solid choice.

A Quality Wallet
Color: Boulder Black - Napa Smooth Black
So far so good. The wallet has a great feel and is of high quality. It looks great and has plenty of credit card slots and I love the bill holder, with a divider. It is wider than I expected, but it stays thinner than the last minimalist wallet I had so the trade off is worth it to me. I would buy it again.
