![]() ![]() When the basic disk uses the GPT partition style, you can create up to 128 primary partitions.Ĭompared with partitions, volumes feature higher reliability and security because data on volumes can be shared with two or more dynamic disks. ![]() When the basic disk uses the MBR partition style, you can create four primary partitions or three primary partitions and one extended partition that can consist of many logical partitions. However, the max number of partitions on a basic disk is determined by the style of partitions that the disk uses. Regardless of whether dynamic disks on a system use the MBR or GPT partition style, you can create up to 2,000 dynamic volumes on them. ![]() Max Number on DiskĪnother difference is the max number of volume and partition on the hard disk. To learn more about the differences between basic disks and dynamic disks, please read the comparison. However, they use a hidden logical disk manager (LDM) or virtual disk service (VDS) to track information about the volumes on them and this decides that dynamic disks are more flexible than basic disks. They use a partition table to keep track of all partitions on them and support two styles of partitions – master boot record (MBR) and GUID partition table (GPT).ĭynamic disks also support MBR and GPT. Note: When you create a partition via Disk Management, you will find that the New Simple Volume option is offered.īasic disks are the most common type of partition used in Windows OS. A volume is created on a dynamic disk, while a partition is created on a basic disk. The biggest difference between a volume and partition is the type of disk used. The other four types of volume can be created on two or more disks and this combines these disks into a large volume, so that’s why the max size of a volume is larger than that of a partition. In contrast, the max size of a volume can be larger – when it is not a simple volume. What is the max size of a partition and a volume?Īs we know, contiguous space on the same disk can be divided into one area, and therefore the max size of a partition is the hard drive space. Logical Drive: Their Exact Features Max Size You might be interested in: Primary Partition VS. Differing from a primary partition, you don’t need to assign a drive letter to it. Logical Partition: it is a contiguous area on the hard disk and it consists of one or more logical partitions.Įxtended Partition: it is a partition that consists of additional logical partitions. The C drive is often a primary partition. Primary Partition: it is a hard disk partition that is identified by a drive letter and is used for storing Windows operating systems and other data. As a fault-tolerant volume, it allows you to recreate the data that was on the failed portion from the remaining data and parity when a portion of a physical disk doesn’t work. RAID-5 Volume: it is a volume with data and parity striped intermittently across three or more physical disks. When new data is written into a spanned volume, data will first fill up the free space on the first disk, the fill up that on the next disk, and so on. Spanned Volume: it combines areas of unallocated space from multiple disks into one logical volume. ![]() This volume type does not provide fault tolerance, which means the entire volume will fail when one of the disks containing a striped volume fails. Striped Volume: it is created by combing areas of free space on two or more disks into one logical volume. If one of the physical disks fails, the data on the disk becomes unavailable, but mirrored volume is a fault-tolerant volume, which means the data on the other physical disk is still usable. When new data is written to the mirrored volume, it will be written to the two copies. Mirrored Volume: it uses two copies on separate physical disks to duplicate data. Simple Volume: it is a physical disk that functions like a physically independent unit. There are five volume types: simple volume, mirrored volume, striped volume spanned volume, and RAID-5 volume, while there are three partition types: primary partition, logical partition, and extended partition. This part compares volume and partition in five different aspects including types, creation, max numbers on a hard disk, max size, and reliability and security. ![]()
