Blu-ray is known for its ability to hold large amounts of HD videos. Depending on the type, a Blu-ray disc can hold up to 128GB of storage space. If you want to maintain a digital Blu-ray library without overwhelming your hard drives, managing Blu-ray capacity is crucial. And to optimize your Blu-ray storage, ripping and compressing Blu-ray discs are two effective methods. This guidepost will teach you how to rip and compress Blu-ray discs. Converting your Blu-ray into a digital format can reduce the file size and enhance device compatibility. Meanwhile, compressing your Blu-ray discs minimizes the disc’s size while retaining the original structure. So, without any further discussion, let’s move on!

Blu Ray Capacity

Part 1. Capacity of Different Blu-ray Discs

As is commonly known, there are only two types of Blu-ray discs: writable and rewritable. In addition to these two types, Blu-ray discs have different storage capacities. This Blu-ray capacity simply determines how much data they can hold in a single disc. Each type offers different storage capacity for various use cases, which we will discuss below:

BD-5

BD-5 is the smallest type in terms of capacity, holding only 5GB. These discs are often used for short clips, small software distributions, and low-resolution video backups. It’s incompatible with standard Blu-ray players as it uses DVD-based media and requires a Blu-ray burner for writing.

BD-9

BD-9 is a slightly larger Blu-ray type with 9GB storage and is also based on DVD. Compared to BD-5, it offers more BD capacity, but its compatibility remains limited to Blu-ray burners. These discs are not ideal for full HD movies or large multimedia projects.

BD-25

BD-25 is the most common Blu-ray disc with 25GB of storage and a single-layer structure. It allows for approximately 170 minutes of full HD video or 22 hours of SD video. These discs are used for commercial Blu-rays, data backup, and personal video archiving.

BD-50

BD-50 is a dual-layer disc that holds 50GB of data, doubling the BD-25 capacity. This additional storage allows for 240 minutes of 1080p HD videos or 46 hours of SD movies. These discs are ideal for longer movies, large data backups, and extended media projects.

BD-XL

BD-XL represents the highest capacity of Blu-ray disks, available in triple-layer (100GB) and quadruple-layer (128GB) versions. These Blu-ray discs are used for 4K UHD movies, archival storage, and large-scale backups. But, they require compatible drivers for reading and writing.
