Then comes the data storage imbalance issue.Įven though it’s possible to set up a RAID with SSD and HDD, the outcome will be an array performing only as fast as the slowest drive. So, if there’s any physical damage to a mixed RAID, the HDD might compromise the integrity of the whole array. HDDs are more fragile because of these moving parts. Right off the bat, there’s a vulnerability issue here. Whereas for SSDs, or Solid State Drive, there are no moving parts whatsoever. It all comes down to how technology is built on these data storage devices.įor HDDs, or Hard Disk Drive, data is written in a disk platter and it is accessed by a needle head that hovers above it. Why You Shouldn’t Do Raid with SSD and HDD And you can combine them with different setups known as RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10 (or 0 + 1). Parity: the calculated value used to restore data from one drive in case the other one failsĮach RAID configuration has its pros and cons, so it will depend on your data storage needs and volume to determine which will suit you best. Mirroring: it keeps an identical copy of data in each disk Striping: it splits data apart equally between the drives

Spanning: it only writes data to the first physical drive until full capacity before writing on the next disk And there are a couple of ways of achieving that according to how you configure multiple disks to work.

Improve fault tolerance by maintaining the ability to function even after one disk failure.īasically, redundancy in RAID is about employing more drives to improve overall power.

Boost performance by allowing input/output operations to overlap in a balanced manner.

Speed up read/write processing time since more drives will work on loading data.

It’s definitely about not keeping all your eggs in one basket.Īlthough a RAID array is not a substitute for a backup, there are great benefits for combining two or more physical drives:

RAID system was created to improve reliability and performance by using multiple disks to handle data storage. Knowing the purpose of a RAID and how it works will help us understand why you shouldn’t mix RAID with SSD and HDD.

When a single hard drive disk is not enough to handle your data storage needs, whether for business or personal purposes, then setting up RAID drives will be your next step up within a budget. Let’s explore why you should not by getting some perspective on what RAID drives really are.

Technically, you can set up your RAID drives configuration employing both SSD and HDD disks simultaneously.īut the real question here, instead of how to do RAID with SSD and HDD is: SHOULD you?

So, is getting the best of both worlds possible? The short answer is no. In fact, when we consider the original acronym for RAID, way back in 1988, Redundant Array of Inexpensive Disks (now Redundant Array of Independent Disks), the main purpose was indeed to increase performance while keeping it affordable. But even though there are great affordable SSD options nowadays, an HDD is still cheaper. This is a valid question, especially when it comes to costs.Īn SSD provides superior performance.

How to do RAID with SSD and HDD combined? Then, your next question will most likely be: There are so many benefits from upgrading your data management setup for a RAID array, that you’ll first ask yourself why you haven’t done it sooner.
