What is the Best SSD for RAID 1?

The best SSD for RAID 1 is one that helps in unleashing the full potential of SSD and, at the same time, provides an extra layer of security to SSD data. 

What Is RAID 1?

RAID 1 or Redundant Array of Independent Disk mode 1 or disk mirroring is a disk subsystem in SSD and HDD. 

RAID 1 is one of many RAID levels that makes use of two disks. The same data is written over the two disks such that data on one disk acts as a savior when the other disk fails. The failed drive can then be replaced with the new one. The working drive of the two then helps in rewriting the lost data to the new disk. This is done with the help of the RAID controller. 

The more the number of drives in the RAID 1 array, the lesser the chances of disk failure. So, SSD with RAID 1 is beneficial for computer systems that demand constant uptime. However, it is highly likely that any of the disks can fail at some point in time. The data of failed disk has to be restored through backups in the absence of a RAID controller. Restoring data from backups may sometimes involve the loss of some data and is even more time-consuming. 

Replacing a failed disk data with a new disk instantly rebuild and writes all the missing data from the remaining drive.

How Does RAID 1 Work?

RAID 1 works by mirroring the same data on two disks. Therefore, it does provide redundancy of data for safety reasons. However, since the data has to be written two times, it is slower in terms of performance. 

Also, it occupies 50% of disk space due to data redundancy. Therefore, you require double the space to store the same amount of data. 

However, RAID 1 is faster when it comes to data recovery and also in reading a written data. 

SATA 3 Vs. M.2 Vs. NVMe – Overview And Comparison

These three are the popular terms used in Solid State Drives (SSD). 

Firstly, talk about the difference between SATA 3 and NVMe. These are the two data used by PC to read the SSD. 

The difference between the two lies in how they are connected to SSD. 

SATA 3 connections make use of data cable and power cable to connect the motherboard and SSD directly. 

On the other hand, NVMe uses a more direct method with the help of the PCI-E slot. An NVMe connection allows SSD to read data straight from the PCI-E slot fitted in the motherboard. This allows SSD with NVMe to read and write data faster than SSD with SATA 3. 

M.2 is different from these two. It is a physical form factor of a drive. M.2 drives are not the protocols like the above two but make use of one. 

An M.2 drive either makes use of a SATA 3 connection or an NVMe connection. So if an SSD is labeled as M.2 drive, look if it uses SATA 3 or NVMe. M.2 drive with an NVMe connection should be preferred over an M.2 drive with SATA 3 if your nature of work involves large files transfer daily. 

HDD RAID Vs. SDD RAID: The Major Differences You Should Know

An HDD RAID can be differentiated from an SSD RAID mainly on three credentials, namely:


People have started shifting from HDD to SDD for a reason. Therefore, an SSD RAID configuration will always perform better than an HDD RAID.

However, since an SSD is expensive, the performance level has to be worth it. Therefore, the performance of an SSD RAID highly depends on the type of RAID controller used and the level of RAID used. 

As there is a negligible difference between SATA 3 SSD and NVMe SSD, it all comes down to using the right RAID level. 


SSD had become more affordable than it used to be when they were first released. However, they are still expensive as compared to HDD. 

If burning a hole in your pocket in buying an SSD is beneficial depends entirely on the purpose of the drive. Basic streaming and file-sharing can well be performed with a mechanical drive with RAID and redundant configurations. 

If you are looking for skyrocketing speeds in handling the data that allows you to afford a disk of 2x the price, go for SSD RAID. 

Reliability of data

When it comes to the reliability and endurance of data, SSD is already better than HDD. Therefore, using SSD RAID for redundancy of data isn’t as meaningful as HDD RAID.

What To Consider When Choosing An SSD For RAID 1?

When choosing an SSD for RAID 1, look for:

1. Energy-efficient drive

SSD with RAID 1 essentially consumes a lot of energy and power. This amounts to using double the consumption a single solid-state drive would take. This is obvious as SSD with RAID 1 means using two drives. Therefore, choosing an SSD that works towards less energy consumption can be considered the drawback equalizer. 

2. Enterprise RAID SSD

Always look for an enterprise RAID SSD and not consumer grade. Consumer-grade SSD with RAID is not designed to handle a group of drives, and therefore a consumer-grade SSD with RAID 1 will be meaningless. 

Enterprise SSD is designed to communicate with the RAID controller such that all the drives work in unison without hampering the device’s performance. 

3. RAID controller characteristics

To allow SSD to run at its full potential, the RAID controller should be able to match up to SSDs abilities. The RAID controller should be fast enough as a slow RAID controller will degrade the performance of even an expensive SSD. 

Should You Make Them The Same Brand And Model?

Yes, try buying an SSD for RAID 1 with the same brand and model.

Is SSD good for RAID 1?

The more the number of drives in the RAID 1 array, the lesser the chances of disk failure. So, SSD with RAID 1 is beneficial for computer systems that demand constant uptime. However, it is highly likely that any of the disks can fail at some point in time.

Which RAID is best for SSD?

In the aspect of performance, SSD RAID is absolutely superior to a single SSD. As we all know, an SSD RAID array configured by multiple SSDs can have an enormous impact on performance. Among these RAID levels, RAID 0 offers the best performance. SSD RAID 0 is also one of RAID levels that individual users may take.

Is SSD good for RAID?

Storage systems generally do not use RAID to pool SSDs for performance purposes. Flash-based SSDs inherently offer higher performance than HDDs, and enable faster rebuilds in parity-based RAID. Rather than improve performance, vendors typically use SSD-based RAID to protect data if a drive fails.

Is RAID 1 a good idea?

When you want to store critical and sensitive data, RAID 1 is your best bet as it mirrors data on two disks, so even if there is a problem with the primary disk, you can always retrieve the content from the second one. In general, RAID 1 is a good choice if data redundancy is a key feature of your storage needs.

Is RAID faster than SSD?

Sadly, when it comes to raw speed, a single SSD is always going to win out against a RAID 0 hard drive setup. Even the fastest, most expensive 10,000 RPM SATA III consumer hard drive only tops out at 200MB/s. In theory.

What type of SSD is the fastest?

List Of The Fastest SSD Drives

  • Kingston 240GB A400 SATA 32.5”
  • Western Digital 500GB.
  • WD_Black 500GB SN750 NVMe Internal Gaming SSD.
  • SanDisk SSD Plus 1TB Internal SSD.
  • Samsung T5 Portable SSD 1TB.
  • SK hynix Gold S31 SATA Gen3 2.5 Inch.
  • Samsung 870 QVO SATA III 2.5 Inch.
  • SK hynix Gold P31 PCIe NVMe Gen3.

Which is better RAID 5 or RAID 10?

One area where RAID 5 scores over RAID 10 is in storage efficiency. Since RAID 5 uses parity information, it stores data more efficiently and, in fact, offers a good balance between storage efficiency, performance, and security. RAID 10, on the other hand, requires more disks and is expensive to implement.

Is RAID faster than single drive?

A common RAID setup for volumes that are larger, faster, and more safe than any single drive. Your data is spread across all the drives in the RAID along with information that will allow your data to be recovered in case of a single drive failure.

Does RAID speed up your computer?

The quickest, easiest and cheapest way to improve hard drive performance is to use RAID 0 or striping, which can roughly double hard drive performance. Most desktop computers already support the software version of RAID 0, and it’s therefore available to almost anyone.

Can I RAID 2 different SSDs?

As discussed earlier, a simple two SSD RAID 0 setup which uses RAID stripe techniques to RAID stripe data between two SSDs can result in a doubling of performance compared to a single SSD, although this setup provides no redundancy.

Is RAID 5 SSD safe?

The write performance of SSD RAID5 is certainly lower as with RAID10, but not significant as with HDDs. The performance of RAID5 may be increased, if you will use power of 2 + 1 disk, for example 5, 9, 17. MTBF is useless for this kind of calculation for a single raid.

What is RAID mode SSD?

Raid was a concept developed for magnetic disks with mechanical parts and wear. Ssds are a completely different technology. Raid setups address two issues. Reliability and performance. While the old, magnetic drives were prone to failure, ssds bring the failure rate in line with other components of the server.

Is RAID 1 enough for backup?

One very important thing to note, RAID 1 is not a backup in and of itself. Although RAID writes data to two disks simultaneously, it is not a backup. If your operating system or software, rather than the hard disk, corrupts your data, this corrupted data is sent to both disks and simultaneously corrupts both drives.

Is RAID 1 considered a backup?

RAID is not a backup mechanism; it’s a redundancy mechanism, and it does a completely different job – one protects against disk failures, the other protects individual files.

Does RAID 1 increase read speed?

Raid1 can potentially improve READ speeds as each disk is read from in turn in much the same way as a striped array, remember, at this point the same data already exists on both disks.

Is RAID used anymore?

It is not often in the IT business that a technology which has been developed many decades ago is still widely used and important for administrators and other users. Even modern servers and storages run with RAID technology inside – mostly in enterprises, but more and more in consumer NAS systems as well.

Is a RAID setup worth it?

RAID is extremely useful if uptime and availability are important to you or your business. Backups will help insure you from a catastrophic data loss. But, restoring large amounts of data, like when you experience a drive failure, can take many hours to perform.

Is RAID important for gaming?

Distinguished. a raid setup will significantly reduce load times, but the actual in game experience will not change.

What are the 3 types of SSD?

There are two different types of SSDs: Serial Advanced Technology Attachment SSDs (SATA) and Peripheral Component Interconnect express SSDs or Non-Volatile Memory express SSDs (PCIe/NVMe/PCIe-NVMe).

Which is best SATA SSD?

Best 2.5-inch SATA SSDs in 2022

  • Samsung 870 EVO.
  • Crucial MX500.
  • SanDisk SSD Plus.
  • Kingston A400.
  • HP S700 Pro.

Are NVMe faster than SSD?

SSD is a secondary storage device that uses integrated circuits to complete its work while NVMe is an interface that is used to access the stored data. NVMe is much faster than an SSD. Solid state devices require less power to function than NVMe does.

Which RAID is best for performance?

The best RAID for performance and redundancy

  • The only downside of RAID 6 is that the extra parity slows down performance.
  • RAID 60 is similar to RAID 50.
  • RAID 60 arrays provide high data transfer speeds as well.
  • For a balance of redundancy, disk drive usage and performance RAID 5 or RAID 50 are great options.

Which RAID is best for read performance?

Advantages of RAID 0

RAID 0 offers the best performance, both in read and write operations. There is no overhead caused by parity controls.

Which RAID has fastest write speed?

RAID0 provides the most speed improvement, especially for write speed, because read and write requests are evenly distributed across all the disks in the array.

Which is better RAID 1 or RAID 10?

RAID 10 blends safety, capacity and write speed. RAID 1 has 4X Read Speed, 1X Write speed and 1X capacity. RAID 10 has 4X Read SPeed, 2X Write speed and 2X capacity. So unless you need truly insane reliability from the drives, RAID 10 is definitely the way to go.

How many drives are needed for RAID 1?

A minimum of two disks is required for RAID 1 hardware implementations. With software RAID 1, instead of two physical disks, data can be mirrored between volumes on a single disk.

What is faster RAID 0 or RAID 1?

Comparison chart

In theory RAID 0 offers faster read and write speeds compared with RAID 1. RAID 1 offers slower write speeds but could offer the same read performance as RAID 0 if the RAID controller uses multiplexing to read data from disks. Where data reliability is less of a concern and speed is important.

What is faster RAID 1 or RAID 5?

Raid 1 has a relatively slow write speed, slower than using a single disk. RAID 5 has a write speed much faster than a single disk, but lags slightly due to the need for creating parity data.

Does raid0 improve performance?

RAID 0 provides a performance boost by dividing data into blocks and spreading them across multiple drives using what is called disk striping. By spreading data across multiple drives, it means multiple disks can access the file, resulting in faster read/write speeds.

What is the most common RAID level?

RAID 5 is perhaps the most common RAID configuration, and unlike RAID 0 and RAID 1, requires a minimum of three disk drives to function. RAID 5 utilizes data striping, whereby data are separated into segments and stored onto the separate disk drives in the array.


This was all about the RAID 1 and other similar concepts to help you buy the best SSD with RAID 1.
