Про AHCI. Если диск один, то AHCI, хотя лучше не засорять систему, а режим SATA в BIOS перевести в совместимость или, как это ещё называют, IDE |

I have just bought a Asus P8H77 VLE SATA 6gbps in my previous MOBO Asus P8H61 MLX there were just two option under SATA control IDE and AHCI but in New Mobo there is one option RAID i have a SSD Kingston V300 120 GB which is SATA 6gbps and a 1 tb Seagate HDD dont know if is its SATA 2 or SATA 3 HDD. My Question is whar should i select here for Better Performance?AHCI or RAID?

Even if I never intend to set up a RAID, I still use it. The drivers tend to be better and you can set up a RAID in the future without any changes to the OS.
AHCI is available option for legacy support (really old IDE drives).

You mean I should Select RAID?in Reality i select RAID but when PC boot there a windows Comes up and and in Green FONT i can saw NO RAID DRIVE..

Can you take a picture of this? You can upload it to www.techpowerup.org
The RAID software should say it is a «non-RAID disk» and that’s normal. You shouldn’t have to go into the RAID setup at all because you’re not using a RAID.
Note: Changing this setting after an operating system is installed is inadvisable.

ugh AHCI is not for really old IDE drives. IDE is for really old IDE drives.
and RAID only expands on AHCI since by default RAID supports AHCI

Wikipedia said:
Many SATA controllers offer selectable modes of operation: legacy Parallel ATA emulation, standard AHCI mode, or vendor-specific RAID (which generally enables AHCI in order to take advantage of its capabilities).

in systems that usually only offer enhanced AHCI or RAID configurations. Just because AHCI (As well as RAID) support IDE drives does not necessarily mean that is what they are for. and since RAID also supports IDE drives. your persistence to use it over AHCI
AHCI is available option for legacy support (really old IDE drives).
Still makes no sense.

The bold section is the «IDE» mode on most motherboards, not AHCI. AHCI’s purpose is entirely for SATA operation. It is what is responsible for the extra features of SATA such as hot swapping and NCQ as well as TRIM support.
RAID mode on the other hand activates the chipsets firmware RAID. If you aren’t actually going to set up a RAID array there isn’t much point in enabling RAID mode. In fact it can actually be limiting in some ways, such as TRIM not working properly on SSDs(big issue with AMD, newer Intel chipsets now allow trim through RAID and Intel actually managed this by making their firmware RAID somewhat AHCI compatible).
Answer to OP’s Question:
If you don’t plan setup RAID, leave it set to AHCI. The reason it pops up in green saying No RAID Drives is exactly that, you don’t have any RAID arrays in the system and no drives in the system capable of making a RAID array. You need at least two, somewhat similar drives in the system to make a RAID array. A 128GB SSD and a 1TB HDD are not similar enough to create a RAID array. So Intel’s firmware RAID is smart enough to not even let you try and just gives you the message.

AHCI, RAID is AHCI but requires more than one drive

You may be right but not for the reason given. When RAID is enabled, the controller gets a boot device in the BIOS but if you don’t go into the RAID config and set a boot device, the BIOS doesn’t know what to run when it is told to boot. This can lead to the error. The solution would be to go into the RAID config and set the appropriate drive as bootable then set the BIOS to boot to the RAID controller.
Alternatively, the drives may show up individually in the BIOS if they aren’t explicitly added to a RAID. Make sure you select the appropriate drive from the RAID list if that is the case.

Simple answer:
Set to AHCI if you aren’t planning to run a RAID array. Set to RAID mode if you are running a RAID array (RAID 0,1,5,10)

You are making it more difficult than it needs to be. Not to mentioned trying to argue over correct information….

I would just set it to AHCI. That’s the most simple way to go. Intel RAID software for drive management still works in AHCI mode so this really is a non-issue. RAID should be used if you plan on using RAID, it’s really that simple.

With Intel RAID, at least on all the recent Chipsets I’ve used(P55, P67, Z68, Z87, Z97), everything connected to the Intel RAID is visible in the BIOS. Multiple RAID arrays appear in the BIOS. So if you create Array_00, Array_01, and Array_02 and have a single lone drive connected all 4 devices will show up in the BIOS just like they are standard hard drives. You pick the boot device in the standard BIOS just like picking a boot drive normally.
What you are describing is usually the process when you are using a 3rd party controller.

True, however the controller itself will still the the RAID controller driver as opposed to the AHCI driver. The biggest benefit in my personal opinion is that if you don’t have chipset drivers installed and it’s set to AHCI, it’s almost certain to pick up the generic Microsoft AHCI drivers where with RAID, it very well might not detect the chipset RAID driver OOTB.
For simplicity sake, I still think using AHCI is a better idea if you don’t need RAID. I see no benefit of running RAID without having a RAID array.

IDE is the old compatible mode, AHCI is the newer SATA2/SSD compatible mode, and RAID is designed for multiple drives working together.
Depending on your controller, you MAY lose some features running the RAID mode, so i highly recommend AHCI.
For example, on some chipsets running RAID meant TRIM would stop working, which negatively affected SSD performance.
AHCI is the ‘safe’ and reliable option if you don’t plan to run RAID any time soon.

Yes — but RAID is a great alternative if you are running with «old fashion harddrives»…. RAID 0 can really speed things up,
(on the cost of secureness in a drive fault situation)

Always use RAID or AHCI on any SATA drives. Remember, using IDE compatibility mode limits the drive to UDMA 133 speeds 133 MB/s which is close to SATA1 1.5 Gbit/s — 150 MB/s. Which is why most people don’t bother with AHCI or RAID for the small gain, but I would..
Hard Drive speeds
- IDE Ultra ATA/33 = .3Gbit/s — 33 MB/s
- IDE Ultra ATA/66 = .6Gbit/s — 66 MB/s
- IDE Ultra ATA/100 = 1Gbit/s — 100 MB/s
- IDE Ultra ATA/133 = 1.3Gbit/s — 133 MB/s
- SATA1 = 1.5 Gbit/s — 150 MB/s
- SATA2 = 3 Gbit/s — 300 MB/s
- SATA 3 = 6 Gbit/s — 600 MB/s
EDIT: Forgot to add that for a single drive I would use AHCI driver over a RAID drive for no other reason than to boot up quicker. Enabling RAID will check your RAID array on startup and give you a chance to change or create a RAID array.

Why did you choose RAID? Doesn’t look like you are running a RAID array.
and TRIM is probably disabled because I do not think your chipset supports TRIM with RAID setting.

You gain bandwidth at the expense of IOPS. Seek latency goes up when you use RAID as all drives needs to get to the same sector and could take different amounts of time to get there. I strongly believe if you need performance SSD is the way to go. If you need mass storage, you’re most likely going to want to keep your stuff safe and will tend to read data more than write it, in which case RAID-5 is superior across the board as you gain redundancy and read performance at the expense of disk space (you get N — 1 drives worth of space) and write performance (as parity blocks must be calculated and written).
However I’ve now been side-tracked… Just go with AHCI. You can always switch to RAID down the road if you even end up caring about such things.
Side note: TRIM being issued to SSDs with the RAID driver depends on the version of RST (or RSTe in my case) as a newer (and unsupported version for X79) was required before I gained TRIM though my RAID. Another way to keep this simple is… using AHCI.

AHCI. While using RAID wont hurt anything, it wont help anything either unless you are actually going to use RAID… but as Aquinas said you can just switch to it without any issues (outside of building your array of course). It was also mentioned that using RAID without an array can increase boot times as it looks for an array.
TRIM has worked in RAID for quite a while now, again as Aquinas said, so long as you have the latest driver (though I recall it being in the chipset/INF/RAID ROM and not the rapid storage drivers??). Update em both.

Where are you getting the 80% number from?

For my case, the latest X79 chipset RAID driver stopped at version 3.6.x.x. TRIM in RAID was added to RSTe in 3.7.0.0 and the latest version for C600 series chipsets is 2.8.0.x last time I checked which was a year ago. I forced installation of the newer RSTe driver to get it to work. It’s also why my RAID driver says C600+/C220+ instead of X79. I had to get creative.

Can i run existing windows 7 with AHCI sata setting?i have installed windows with Raid when i boot windows changing from raid to ahci it goes to blue screen error for eye blink time and restart again.is there any method?
If you have ever set up a computer, you may have encountered the “RAID” or “AHCI” settings within the UEFI/BIOS settings. If you are confused about what those are and which one you should select, you have come to the right place.
In this article, we discuss what AHCI and RAID are, how are they different, and which one you ought to select to maximize the system performance.
Table of Contents
SATA Operation Protocols
“SATA operation” is a configuration you will likely encounter when browsing through your BIOS/UEFI settings. Serial ATA (SATA) is a hard disk interface that also defines the protocol your system uses to transfer data to and from the hard disk.
Within the “SATA Operations” setting, you can choose from one of the following options:
- IDE
- AHCI
- RAID
Integrated Drive Electronics (IDE) is another standard the motherboard uses, which defines the transfer protocol to and from a hard drive. However, this protocol is slowly diminishing because of more modern and advanced technologies, like RAID and AHCI.
If you do not have the “IDE” option, you can surely “disable” the SATA operation settings. This will automatically select the IDE protocol.
What is AHCI?
The Advanced Host Controller Interface (AHCI) is a transfer protocol defined by Intel that you usually see in newer computers. This is a relatively new technology, currently only limited to Intel chipsets. The AHCI technology controls how data is transferred to and from a hard drive, or SSD, with a SATA interface.
Selecting AHCI will improve the performance of the data transfer speeds, as well as add new features. For instance, AHCI allows hot swapping, which means you can connect or disconnect hard disks on the go.
Additionally, it also has Native Command Queuing (NCQ), which is a method to optimize how simultaneous data requests are handled.
AHCI is primarily used for SSDs, but can also be used on legacy mechanical hard drives. However, it does not have significant improvement gains on hard drives compared to other brands. Although AHCI doesn’t affect the SATA port’s performance, it gives users access to its more sophisticated features.
What is RAID
The Redundant Array of Independent Disks (RAID) is a storage virtualization technology that can virtualize one or more hard disks into one or more arrays. In simple words, it can virtually combine multiple hard drives and make them seem like a single drive.
If configured correctly, RAID can improve the performance, reliability, and availability of the storage hardware. See more about RAID levels here (RAID 0, RAID 1, RAID 5, RAID 6, RAID 10).
RAID can be configured on SSDs, mechanical hard drives, or a hybrid of the two. However, it is ideally used for hard drives or a hybrid setup, since RAID has the most performance impact on them. RAID configuration on SSDs has no significant impact on performance, but only merges them into one big volume.
On client machines, you can choose between AHCI and RAID only. However, on servers and enterprise environments, you can choose from the different types/levels of RAID. Here is a table that defines the different levels of commonly-used RAID configurations and their functionality:
| RAID Level | Functionality | Details |
| RAID 0 | Striping | Merge multiple hard drives into one large volume |
| RAID 1 | Mirroring | Mirror the data from one hard drive onto another for redundancy |
| RAID 5 | Striping + Distributed Parity | Merges data between 3 hard drives and also distributes parity information amongst them. You can lose one hard drive and still have all your data. |
| RAID 6 | Striping + Distributed Parity | Merges data between 4 hard drives and also distributes parity information amongst them. You can lose two hard drives and still have all your data. |
| RAID 10 | Mirroring + Striping | Merge half of the hard drive into one large volume and mirror it onto the other half of the hard drives |
The RAID level available on most client computers is RAID 0 – which merges all the drives into one large volume. You do not have the option to choose a different RAID level.
When you use RAID on 2 or more hard drives, it uses their combined rad and writes speeds to move the data. This significantly improves the overall read-and-write performance by combining power from multiple drives.
Now that you understand what AHCI and RAID are, let us do a quick comparison.
AHCI vs RAID: Which is Better for Performance?
Before we answer which is better: AHCI or RAID, let us summarize the pros and cons of the two technologies in this table:
| AHCI | RAID |
| Cannot merge multiple hard drives | Merge multiple hard drives into one large volume |
| Jump in performance on SATA SSDs | No significant performance improvements on SSDs |
| No significant performance improvements on mechanical disks | Drastic performance improvements on mechanical disks |
| Exclusive for Intel chipsets only | Supported by many vendors |
| Allows hot swapping | Does not allow hot swapping |
| Improves multi-user performance using NCQ | Does not have NCQ |
| Does not offer redundancy | Provides data redundancy |
| can be expanded as long as the hardware allows | More scalable by allowing further expansion of disks |
| Easier to manage | Relatively difficult to manage as disk configuration must be the same across all disks |
| Can replace a failed disk when needed while other data is available | The array will become unavailable until the failed disk is replaced. |
| The entire storage space is usable | Half of the storage space is usable |
Both AHCI and RAID have their perks and downsides. In the end, it all comes down to what configuration you have.
If you only run a single SSD, then AHCI would be the better choice. If running two SSDs and merging them is not a priority, then AHCI might still be the better choice.
However, if you are running 2 or more mechanical hard drives, you may want to choose RAID, as it will significantly improve the performance of the data transfer.
If you find that your computer has neither options to choose from, it means it does not support AHCI nor RAID configuration. However, you can still use the Windows “Storage Spaces” feature. This feature allows you to merge 2 or more drives into a single or more array. One can say that this is Microsoft’s version of RAID.
Conclusion
In the end, it all comes down to what hardware your system has and which configuration you want. If you want data redundancy and are not prepared to lose valuable data, we suggest you use the RAID configuration. If you have one or two SSDs, and securing your data is not your priority, but performance is, then AHCI is the way to go.
Note that you must select one of these configurations before Windows installation. Changing your choice later may require reinstallation of the OS.
That said, IDE is old technology and has no significant benefits. This is why we suggest you choose either RAID or AHCI, not IDE.
Frequently Asked Questions (FAQs)
What’s the difference between AHCI and RAID?
AHCI and RAID are both data transfer protocols used between a motherboard and a SATA hard disk storage device. AHCI is limited to Intel chipsets only which offers performance gains. However, RAID (0) offers data redundancy, which means that your data from one hard drive is mirrored onto another, securing your data in case of a disaster. However, only half of the disk space is usable in the case of a RAID configuration.
How to change AHCI to RAID or RAID to AHCI?
The SATA transfer protocol can be changed from the system’s BIOS/UEFI settings. Restart your computer and enter its BIOS using the One Time Boot Menu (F2/F12 function key – depending on your manufacturer), and look for “SATA Operation,” usually available under system configuration.
How to update the SATA AHCI/RAID controller?
The AHCI or RAID controller can be updated like all other drivers on a Windows PC. Here is how:
1. Open the Device Manager by typing in devmgmt.msc in the Run Command box.
2. Expand “IDE ATA/ATAPI controllers.”
3. Right-click on the controller and click “Update Driver.”
4. Click “Search automatically for drivers.”
