Your Essential Guide to Buying Direct Attached Storage (DAS)
Direct Attached Storage, or DAS, is a straightforward way to add extra storage space directly to your computer or server. Think of it as plugging in a powerful external hard drive, but often with more options for speed and capacity. This guide helps you pick the best DAS for your needs.
Key Features to Look For
When shopping for DAS, focus on these main features. They decide how fast and how much data you can store.
- Connectivity: How does the DAS talk to your computer? Look for modern connections like USB 3.0, USB-C, Thunderbolt 3 or 4, or eSATA. Faster connections mean faster file transfers.
- Drive Bays: This is how many hard drives or SSDs fit inside the DAS enclosure. More bays mean more storage space. Some enclosures hold just one drive, while others hold eight or more.
- RAID Support: RAID (Redundant Array of Independent Disks) combines multiple drives for better speed or better safety. Simple RAID levels like RAID 0 (speed) or RAID 1 (safety copy) are common in DAS units.
- Drive Type Support: Check if the DAS accepts Hard Disk Drives (HDDs), Solid State Drives (SSDs), or both. SSDs are much faster but usually cost more per gigabyte.
Important Materials and Build Quality
The materials used in the DAS enclosure affect how long it lasts and how well it keeps your drives cool.
Enclosure Construction
- Aluminum or Metal Chassis: Good quality DAS units usually have sturdy metal casings. Metal helps pull heat away from the drives, which keeps them running cooler and safer.
- Plastic Casing: Cheaper units sometimes use more plastic. While lighter, plastic does not dissipate heat as well as metal.
Internal Components
The controller chip inside the enclosure is very important. A good controller manages the data flow efficiently, which boosts your speed, especially when using RAID.
Factors That Improve or Reduce Quality
Several things make a DAS system better or worse for you.
Boosting Quality (What Makes It Good)
- Tool-Less Design: The best units let you swap drives without needing a screwdriver. This makes upgrades and repairs very easy.
- Quiet Fans: If you work in a quiet office, look for units with large, slow-spinning, or quiet fans. Some high-end DAS units are fan-less.
- Hardware RAID: DAS units that handle RAID calculations themselves (hardware RAID) perform better than those that rely on your computer’s software (software RAID).
Reducing Quality (What Makes It Bad)
- Proprietary Drives: Some manufacturers force you to use only their specific, often expensive, hard drives. Avoid these if you want flexibility.
- Poor Heat Management: If the casing gets very hot during use, the drives inside will wear out faster. This reduces the overall quality and lifespan.
- Slow Controllers: If the connection speed (like USB 2.0) is much slower than the drives inside can handle, you waste money on fast drives.
User Experience and Use Cases
How you plan to use the DAS heavily influences which model you should buy.
For the Everyday User (Backup and Media)
If you just need a big place to back up photos or store movies, a simple one or two-bay DAS connected via USB 3.0 is perfect. Ease of use is the main goal here.
For Creative Professionals (Video Editing and Design)
Video editors need speed. Look for DAS units with Thunderbolt connections and SSDs set up in a fast RAID configuration (like RAID 0). This lets you edit large 4K video files directly from the storage without lag.
For Small Businesses (Data Safety)
Safety matters most for business data. Choose a multi-bay DAS (four or more bays) that supports RAID 5 or RAID 6. This setup protects your data; if one drive fails, you do not lose any information.
Frequently Asked Questions (FAQ) About DAS
Q: What is the main difference between DAS and NAS?
A: DAS connects directly to one computer using a cable (like USB or Thunderbolt). NAS (Network Attached Storage) connects to your router and can be accessed by many computers over the network.
Q: Do I need to buy the drives separately?
A: Many DAS enclosures are sold empty, meaning you must buy the hard drives or SSDs separately. Some “plug-and-play” models come pre-loaded with drives.
Q: Is DAS faster than a regular external hard drive?
A: Often, yes. DAS enclosures allow you to use multiple drives in a fast setup (RAID) and often use faster connection ports like Thunderbolt, which regular external drives might not support.
Q: What is the best connection type for speed?
A: Thunderbolt 3 or 4 generally offers the fastest connection speeds available for DAS, especially if you are using many fast SSDs.
Q: What is RAID 1, and why should I use it?
A: RAID 1 mirrors your data. Every file you save on one drive is instantly saved on a second drive. If the first drive breaks, your data is safe on the second one.
Q: Will a DAS unit make a lot of noise?
A: Noise depends on the fans and the drives inside. SSD-only DAS units are usually quiet. Units with many spinning HDDs and active cooling fans can produce noticeable humming or whirring sounds.
Q: Can I upgrade the drives later?
A: Yes, most good DAS enclosures allow you to easily swap out smaller drives for larger ones later on, though you must follow the manufacturer’s guidelines for rebuilding the RAID array.
Q: Do I need special software to set up DAS?
A: For basic single-drive use, no special software is required; the computer sees it like any other drive. For setting up RAID, you often use simple software included with the DAS or settings in your computer’s operating system.
Q: Does DAS use a lot of electricity?
A: Yes, DAS units use more power than a single external drive because they have multiple drives and often cooling fans running constantly.
Q: Is DAS safe from viruses?
A: DAS protects your files physically, but it does not protect against software threats. If your computer gets a virus, the virus can still copy itself onto the files stored on your DAS.
