To set up over provisioning on Crucial SSDs, you should utilize the Crucial over provisioning tool called Storage Executive.īut before setting up over provisioning on Crucial SSDs using the tool, you should make sure your Crucial drive is supported by the Crucial over provisioning tool and is ready for over provisioning to be enabled-there should be a separate partition with a drive letter listed at the end of the SSD.

The Largest Consumer SSD Drives: Samsung 850 Pro and Evo 2TB SSD Set up Over Provisioning on Crucial SSDs Once the task finishes, the over provisioning has enabled. Generally, the ideal OP (%) is 10% but the higher the better.

Step 4: Once the tool completes scanning, click the Set OP button at the bottom right corner to set the amount you want to allocate. Then, navigate to the Over Provisioning option in the left panel. Step 3: Once the tool launches, you can see your Samsung SSD is listed in the right panel.

Let’s see how to set up provisioning on Samsung SSDs. Samsung allows its users to use Samsung Magician to adjust the default OP (6.7%) of DC SSDs. Set up Over Proversioning on Samsung SSDs If you are using SSDs of other brands, there is also a trick. Although SSD manufacturers have allocated a certain space of SSDs for OP, Samsung and Crucial allow you to adjust the size of the space if you require additional OP on their SSDs. OP can prolong SSD lifespan and boost SSD performance.

Increase SSD lifespan: OP can make SSDs work more smartly, so wear and tear will be minimized on SSDs.

So, overprovisioning increases SSD performance and even maintains SSD performance over time.

Boost SSD performance: OP offers the flash controller extra buffer space for managing P/E cycles and ensuring a write operation will have immediate access to a pre-erased block.

Reduce power consumption: Thanks to OP, SSD controllers can operate quickly, resulting in less power from devices to complete tasks.

In this case, OP gives controllers extra free space needed to move data and results in faster execution.

Reduce time for Garbage Collection: As previously stated, GC creates free blocks to temporarily store data while erasing blocks of invalid data.

OP (%) = ((Physical Capacity – User Capacity) / User Capacity) * 100įor instance, when 60GB of a 64GB SSD is used as the user capacity, 4GB is allocated to the OP and the OP (%) is about 7%.

SSD over-provisioning (OP), the inclusion of extra storage in SSDs, is inaccessible to users and is not displayed in the host operating system. The process creates a permanent swap space to SSD’s controller to manage all the data traffic and storage for SSDs. To address the challenge, during firmware programming, manufacturers allocate a certain percentage of an SSD capacity for extra write operations and the extra capacity is called over-provisioning. However, the GC process also presents a new challenge-it interferes with the host write. This process is to create free blocks within SSDs by collecting valid pages into a single location and erasing the blocks containing invalid pages. To maintain the write performance, a process called garbage collection (GC) is utilized. However, the first erasing process and then the writing process will decrease the overall write performance of SSDs. Therefore, data won't be overwritten on SSDs. Existing data must be erased to write new data. Data on SSDs is read and written at the page level but is erased at the block level. Why? Keep reading.Įach NAND flash memory consists of several blocks and each block consists of around 128 pages. Due to this, the data on SSDs cannot be overwritten when new data is written in. How Do SSDs Store Data?Īs we know, SSDs store data relying on NAND flash memory.

To better understand what SSD over-provisioning is, let’s first learn how data is stored and erased on SSDs.
