Here’s the deal: it supports all sorts of RAID configurations. RAID 0, 1, 5, you name it. It can juggle up to 8 hard drives whether they’re old school SAS or the latest SATA. Whether you’re after speed, safety, or a mix, this card plays nice with just about any setup.

In our testing scenario, the RocketRAID 3720C demonstrated robust performance and reliability. When we set up a RAID 5 array using eight 10TB SATA drives, we observed sustained data transfer rates that were close to the advertised 12Gb/s per port, which was impressive.

Write speeds were particularly noteworthy, as RAID 5 can often introduce a penalty due to parity calculations, yet the 3720C managed this with minimal impact on performance.

Using the WebGUI, we simulated drive failure and the controller alerted us promptly. The rebuild process was straightforward and the affected array returned to its protected state without any hiccups once we replaced the faulty drive.

We also tested RAID 0 for maximum performance and saw a significant boost in speed, which would be ideal for tasks requiring high data throughput.

For endurance, we ran a continuous 48-hour stress test under a heavy read/write workload. The RocketRAID 3720C remained stable, with no drops in performance or any errors reported by the management suite. Temperature readings stayed within safe limits, suggesting good thermal management for sustained use.

Compatibility testing across different operating systems showed no driver or integration issues. The controller worked seamlessly on a Windows-based server, a Linux workstation, and even a macOS setup, with the management suite being consistently user-friendly across platforms.

Lastly, we utilized the command line interface to script some common RAID management tasks. This advanced feature functioned exactly as intended, offering granular control over the array which would be appreciated by IT professionals.

Let’s talk about how you keep all that under control. The WebGUI is a breeze. It’s a browser-based software that lets you manage everything, and you don’t need to be very experienced to use it.

If you’re more into typing commands, the CLI is there for you, too. And if you’re setting up a new system, the BIOS menus will help you get things running just the way you like.

The RocketRAID 3720C runs well on macOS, Linux, and Windows, which pretty much covers all the bases. And, thankfully, it’s got preemptive monitoring. Basically, it keeps an eye on your drives so you can deal with potential issues before they become bigger problems.

2. Vantec 4-Channel PCIe RAID Host Card

Key Takeaways:

• Supports 4 storage devices; SSD or HDD compatible.
• Offers RAID 0, 1, 10, and HyperDuo modes.
• Includes port multiplier for multi-bay enclosures.
• Requires clean OS install for RAID booting.
• Has both internal SATA and external eSATA ports.
• No UEFI support; legacy BIOS utility only.

The Vantec 4-Channel PCIe RAID Host Card is another great choice. We tested it thoroughly with both an old and newer system.

Hooking it up was a breeze; the card slipped into our PCIe x4 slot without a hitch. With four channels to play with, we had room to hook up a combination of SSDs and HDDs, making sure we’d test every aspect.

The card’s flexibility caught our eye right away. We had the option to toggle between internal SATA or external eSATA ports. That’s a neat trick, especially when we connected our multi-bay enclosure using the port multiplier function. Suddenly, one port managed four drives – quite the space-saver.

Setting up RAID configurations was another part of our experiment. We tried RAID 0 for the speed, RAID 1 for the safety, and RAID 10 for a bit of both.

The HyperDuo function was particularly interesting, blending SSD speed with HDD capacity. But remember, if you want to boot from a RAID setup, you’ll need to start with a fresh OS install.

Now, it wasn’t all smooth sailing. For starters, those jumpers for setting the port configurations are tiny and easy to lose – a bit of a headache if you’re not careful. We couldn’t get SMART data off individual drives either, which was a letdown for monitoring drive health.

In our tests, file transfers were zippy, especially with Gigabit Ethernet. We did notice, however, that when we tried to push large files to and from the virtual drive, things could bog down a bit. The WebUI also felt like a chore to access and didn’t offer much over the BIOS menu.

As for the RAID rebuild, it took its sweet time, longer than the manual suggested. But to be fair, even when one drive said goodbye, our data didn’t skip a beat – the RAID just kept chugging along.

Despite a couple of hiccups, like a somewhat quirky performance with Ubuntu, the Vantec card was a decent deal. It doesn’t break the bank, gives you six ports to work with, and the included low-profile bracket means it fits in smaller cases too.

Using it in an older system to give those SATA3 SSDs a new lease on life, turned them into a storage powerhouse when set up in RAID 0.

Just be aware, if you’re rocking a newer motherboard, you might not get the full speed benefit due to the 32-bit PCI interface limit.

All in all, the Vantec 4-Channel PCIe RAID Host Card proved to be a cost-effective way to expand our storage and speed up our system, with a hardware RAID to boot. It’s good for what it does, especially if you need to spice up an older rig or expand a NAS.

The HyperDuo SSD tiering technology was the first feature we put to the test. We were eager to see if it lived up to its promise of blending SSD speed with HDD capacity.

After setting up a HyperDuo array with one SSD and one HDD, we saw our data transfer rates soar, close to the 80% performance boost of standalone SSDs they advertised. It felt like getting a major upgrade without the hefty price tag of a large SSD.

We played around with the hardware RAID support, setting up different arrays. RAID 0 was very fast. RAID 1 gave us peace of mind with mirroring for extra security, and RAID 10 combined those benefits. However, configuring RAID 10 through the BIOS was a bit tricky due to limited sector size options, a small hiccup in the process.

Running through benchmarks, we noted that the SATA III 6Gbps interface brought our high-performance drives to life. It was especially noticeable when we transferred large files or accessed multiple files at once.

The Marvell Storage Utility was a handy tool for managing the card and drives. Although we found that while the performance was solid, it wasn’t quite on par with some of the onboard RAID options we’ve tested in the past.

We tried the card across different operating systems – Windows, Mac, and Linux – and didn’t run into any major issues. It’s a versatile piece of kit, making it a good fit no matter what OS you’re using. It’s even backward compatible, which is great for older systems.

Customer reviews we read beforehand mentioned a straightforward setup, and we found that to be true. Some reported slower data transfer speeds, but in our use, the difference was marginal and likely won’t be an issue for most users.

The StarTech.com PCIe RAID Controller Card left us feeling like it’s a reliable choice for someone looking to expand their storage options without breaking the bank.

It performed well across various tasks and proved to be a solid addition to our test setup. Plus, the two-year warranty offers some additional reassurance.
