I am curious to compare hard disk and RAID array performance results, to see the differences between Hardware RAID, FakeRAID, Software Raid, the different types of RAID (0, 1, 5, 0+1, ...), and no RAID at all.

I invite you to post a brief summary of your system setup, and the results of running bonnie++.


sudo apt-get install bonnie++ && bonnie++

My Setup:

Hard Disks: 2x500GB Seagate Barracuda running in a Software (mdadm) RAID1.
RAM: 6GB DDR2
CPU: 1.89GHz Intel Core 2 Duo E6300
Filesystem: ext4
Ubuntu version: 10.04

Thanks for posting! The comparison of our results is as expected:

We have similar write speeds (though yours is overall a bit faster), I have around double block read speed from having a RAID1 with 2 disks to read from. But overall, I have more CPU overhead. Interesting!

Completely off topic, but - When I first read the thread title I thought "gee, isn't this the kind of thing I keep finding in my spam folder??"

@The Real Dave

The results from bonnie++ are a bit confusing, but some reference points are the Sequential Output Block and Sequential Input Block. You're getting ~ 45MB/s , which is typical of 7200 RPM magnetic drives.

My hdparm -tT results are:


/dev/md0:
Timing cached reads: 2588 MB in 2.00 seconds = 1293.95 MB/sec
Timing buffered disk reads: 296 MB in 3.00 seconds = 98.55 MB/sec


I think I have 32M cache on both my 500GB drives.

Ouhhh there we go... Nice speeds! 204Mb/s block read is pretty awesome!

I wonder why RAID0 offers better read speeds than RAID1? Shouldn't RAID1 be able to read in a similar manner?

RAID 1 and RAID 0 are very different. RAID 1 clones data between multiple discs. It is good for fault tolerance. Theorictically it should have the performance of a single disc, altough I have seen it slightly lower.

RAID 0 splits the data between multiple discs. It is fast, but if one disc fails, then you lose all your data. I use this computer for gaming and general usage. So if I lose data its OK because I backup everything on my server. I am running this test on it right now. I will post results shortly.

That's an impressive setup! That means you effectively get 2.25 TB of storage, correct?

If you don't mind my asking, why are you using such an array? Are you running a server? And what made you choose RAID5 over RAID0+1?

Yes, its about that much storage. It was all pretty cheap for how much storage I have. I got the RAID controller off Ebay for just under $100 and each hard drive was only $70 from Newegg. I choose RAID 5 because you utilize more storage without sacrificing redundancy as compared to RAID10. This system is just a file server and toy for playing with Linux.

I just realized I made a mistake. I didn't look at the performance until now. I forgot the OS was on a separate disk. I will update the performance numbers after the test completes.

Results for my encoding server.

Setup

CPU: 2.6GHz Intel Celeron [128K]
RAM: 256Mb DDR
HDD: 20+80GB Seagate IDE [8Mb]

* Small [~50MB] /boot partition on the 20GB drive
* 1GB RAID0 swap [500MB per drive, md0]
* ~99GB RAID0 / [remaining space on drives]

Both drives are on the same cable. Shows how little things like that, and the drives being the same effect performance.

80GB Drive

/dev/sda:
Timing cached reads: 470 MB in 2.00 seconds = 234.84 MB/sec
Timing buffered disk reads: 60 MB in 3.02 seconds = 19.89 MB/sec


20GB Drive

/dev/sdb:
Timing cached reads: 478 MB in 2.00 seconds = 238.76 MB/sec
Timing buffered disk reads: 104 MB in 3.02 seconds = 34.42 MB/sec


1GB Swap, identical Soft Raid0

/dev/md0:
Timing cached reads: 462 MB in 2.00 seconds = 230.57 MB/sec
Timing buffered disk reads: 78 MB in 3.02 seconds = 25.81 MB/sec


~99GB / , unidentical Soft Raid0

/dev/md1:
Timing cached reads: 466 MB in 2.00 seconds = 232.49 MB/sec
Timing buffered disk reads: 80 MB in 3.03 seconds = 26.38 MB/sec


Turns out that I get roughly the average of the two drives by themselves, which ain't bad at all. Just posting for thought food :)

And of course, temps

Actually, it looks like your performance, at least for block read/write, is on par with some desktops we've seen!

@The Real Dave

Hmmm.. I'm actually surprised that your RAID0 isn't giving you more of a performance boost! Maybe since it's a softraid, the CPU might be a limiting factor? I've seen plain RAID0s with upwards of 90MB/s block read/write!

Just for the sake of it, I'll post some hdparm results for some of my other drives.

Again, my RAID1 (2 x Seagate 500GB w/ 32 MB cache)

/dev/md0:
Timing cached reads: 2514 MB in 2.00 seconds = 1256.63 MB/sec
Timing buffered disk reads: 220 MB in 3.02 seconds = 72.75 MB/sec

An old Maxtor 200GB drive with 16MB cache:

/dev/sdc:
Timing cached reads: 2280 MB in 2.00 seconds = 1139.85 MB/sec
Timing buffered disk reads: 166 MB in 3.01 seconds = 55.10 MB/sec

A newer Seagate 1TB drive with 32 MB cache:

/dev/sdd:
Timing cached reads: 2462 MB in 2.00 seconds = 1231.13 MB/sec
Timing buffered disk reads: 380 MB in 3.01 seconds = 126.33 MB/sec

Weird that my 1TB drive reads faster than my RAID1 array...

It's not that weird. Hard drive manufacturers focus on increasing capacity and speed. Higher density drives are faster. So newer and larger hard drives are faster. Besides, RAID1 is theoretically only as fast as one individual drive.

Completely off topic, but - When I first read the thread title I thought "gee, isn't this the kind of thing I keep finding in my spam folder??"

Oh thank goodness I thought I was the only one who got that stuff.

@The Real Dave

Hmmm.. I'm actually surprised that your RAID0 isn't giving you more of a performance boost! Maybe since it's a softraid, the CPU might be a limiting factor? I've seen plain RAID0s with upwards of 90MB/s block read/write!

Possibly, but I've never seen the CPU usage spike under using the RAID :confused:

You would have to have a very underpowered processor or under very heavy load to have your processor effect your array performance.

Ah ok, cheers. Probably the fact that both drives are on the same channel, or that the drives are dissimilar so.

That will do it. You can only get optimal performance from the same model drives.

Actually, it looks like your performance, at least for block read/write, is on par with some desktops we've seen!

Cool,

I actually find the Asus EEE's performance to be okay as whole. But I noticed a mild amount of lag in somethings so I figured the hard drive must be slow. Maybe I need to run some benchmarks on the GPU, RAM and CPU.

For example: Firefox, Open Office and vuze run slow where as Gnome, Gimp and even Open Arena run fine. I've yet to figure out why, I think firefox doesn't like Atom based CPUs.

It could be that he has processor power saving modes enabled. For example, my processor (3.7GHz) drops its multiplier down to 4x when idling, which is 800MHz.

Wow, a lot of these results are somewhat surprising! What I'm most impressed by is the laptop drive performances. Some of you guys posted laptops that do 60MB/s sequential read, that's awesome!


It's not that weird. Hard drive manufacturers focus on increasing capacity and speed. Higher density drives are faster. So newer and larger hard drives are faster. Besides, RAID1 is theoretically only as fast as one individual drive.

I guess what you're saying really is true, as demonstrated by these results!

What about some SSD performances? I'm curious to see what all the hype is about... Some boast 220 MB/s sequential read!
