⚡ JMB585 Chipset Advantages

The JMB585 is a premium SATA controller that offers superior performance and stability compared to budget alternatives:

  • vs. ASM1166: Better driver stability, superior multi-drive performance with FIS-based switching
  • vs. Marvell 88SE9215: Higher bandwidth utilization, improved NCQ implementation, better Linux compatibility
  • Native AHCI Support: Works out-of-the-box without proprietary drivers in Windows 7+ and Linux

💡 Common Use Cases

🖥️ Storage Expansion

Add up to 5 SATA drives (HDD/SSD) to motherboards with limited SATA ports. Ideal for media servers, NAS builds, and workstations.

⚙️ Legacy System Upgrades

Upgrade older PCs with SATA II or limited ports to modern SATA III speeds without replacing the motherboard.

📊 Data-Intensive Workflows

Video editing, photography, 3D rendering — connect multiple high-speed SSDs for scratch disks and project storage.

🔬 Testing & Development

IT professionals testing multiple OS installations, benchmarking storage, or running software RAID configurations.

❓ Frequently Asked Questions

Q: Do I need to install drivers?

A: Windows 7/8/10 include native drivers — the card works immediately after installation. Linux 2.6+ also has built-in support.

Q: Can I boot from a drive connected to this card?

A: Yes! The card supports UEFI boot. You may need to enable "AHCI" mode in your BIOS and set the card as a boot device.

Q: Does this card support RAID?

A: This is a non-RAID controller (JBOD mode only). However, you can use Windows Storage Spaces, Linux mdadm, or other software RAID solutions.

Q: What's the difference between JMB585 and cheaper chipsets?

A: JMB585 offers superior multi-drive performance with FIS-based switching (prevents bottlenecks), better driver stability, and 1,700 MB/s aggregate bandwidth. Cheaper ASM1166 and Marvell controllers often struggle with simultaneous drive access.

Q: Are SATA cables included?

A: No, SATA data cables are sold separately. You'll need standard SATA III 6Gb/s cables (straight or right-angle connectors depending on your case layout).
