Are 15k RPM SAS hard drives noisy?

Hey everybody,
I have the option of getting a couple of 150 GB 15k RPM SAS drives for a negligible amount of money; I'm interested in their speed but I'm concerned about noise issues. I already own an aging 36 GB 10k RPM WD Raptor drive which I never thought was that noisy, but 10k to 15k sounds like a big jump to me, and as I build my upcoming new computer, I'm trying to keep it as quiet as possible.
Now I know SSDs are the fashionable answer to both speed and silence issues but that would push me way past my budget for my new computer.
So how noisy are those 15k RPM hard drives really? Keep in mind they would be destined for an ordinary gaming PC which I'm trying to keep as quiet as possible.

As a side question, ignoring noise: are 15k RPM drives really worth it for what will be a gaming and everyday use PC? By getting those drives I am condemning myself to having to buy an Asus P6T WS Pro instead of the P6TD I have in mind, or get the latter and a separate PCI-Express SAS controller so I can run those drives.

Think it's worth the hassle or shall I just wait until I can budgetize an SSD drive at some point down the line?

I would suggest you get a SSD instead.

15k is looouuuddd as hell. My dad used to have a server at work (until he got some VPS space) with a couple 10k's and 4 or 5 15k's. The thing was loud and slightly annoying, and you could even hear the drives seeking around as data was moved.

If you're even remotely concerned with noise, go with SSD's.

Some SSD's are unfortunately very jumpy, HDDs are more stable. But if your mainly concerned about the noise, get an SSD. Try get a OCZ Agility series of SSD, mainly because they are one of the best SSD's on the market. Intel's a pretty good choice too, but they are extremely pricey.

Ok. I guess I'll pass on the 15k RPM drives then

On Monday morning I was in the data room of one of my company's locations and they have a database server there with a few of those drives, it is true that you can hear them seek, and even that is loud considering it's just seeking...

Like I said SSD drives are out of my budget right now so for my new computer I'm stuck with using older SATA hard drives I have lying around from a couple of computers I got rid of a while back.

Well, thank you for the responses!

Woah!

Before you pass on the drives, check the model numbers. The latest drives are FAST - we're talking sequential reads that many SSDs can't match. Obviously they can't match SSDs for random access, but if they are cheap they might be worth a punt. You can get a RAID0 SAS-capable controller from eBay for pennies if you know what you are looking for.

The latest 15K drives are also much quieter than earlier drives. If you don't consider your Raptor loud (and IMO the Raptors were pretty deafening), then you will be fine with recent 15K disks. The smaller platters in the high-speed drives means they can actually be quieter than their 7200rpm brothers - hence the reason why SPCR have the V-Raptors as one of their recommended disks. Take off the silly IcePAK & they really are quiet. I have 4 10K.2 Seagates, and they are as quiet than the WD 7200rpm RE3s that they sit next to in my server.

Basically - if you can get a few drives for a decent price, why not give them a try? Don't bother changing your mobo, buy a Dell SAS 6i/R or HP SC40Ge and give them a whirl...

I'm pretty sure the P6T Deluxe V1 has an SAS controller. I'm pretty sure because I have one, but I'm not positive because I don't use it, and they seem to have taken it off the V2.
Remeber now that 15k HDDs are meant for Enterprise datacenter/server duty. Sound is not an issue for them. With all the air handlers, cooling fans and other equipment in a datacenter its very loud already.
Depends on your fans... I never hear mine. Prolly because my two delta's running full blast are drowning it out.

I checked what the drives are and they are Fujitsu drives manufactured 05/2008 that came with IBM xSeries rack-mounted servers. So apparently these aren't the latest and greatest and they are definitely not Seagate. Should that make a difference in my considerations?

1 year old SAS drives for cheap? Sounds like a bargain. Pretty much all the SAS drives available have excellent performance - there is no room to screw up in the enterprise world, as huge companies are willing to pay for quality but will get very angry very quickly with lower quality products. It wouldn't be worth IBM's time to consider lower performing drives.

If you can get a good price I'd go for them - what exactly is the deal?
Speaking of air cooling, do 15k drives get crazy hot? If there are smashed against each other in a small case that could be a big problem right?
They are clicky, and whirry and whooooooooooshy.

I would try and keep at least half a drive space between them, and make sure they have active airflow.

They use ~18W or so full seek - so get a bit toasty.

But the ~5ms access times are pretty tastey for a mechanical drive...

I think I have the very drives you're looking at. This drive - 4 of them in RAID5 on my PERC 5/i, in fact. They're fairly quiet, except when doing extended seeks you can hear them seeking, but most of the time I can't hear them over my case fans.

I wouldn't use these in an HTPC or other silent build. But that's not what they're for in the first place. In a workstation you're not very likely to notice. Personally I like hearing the drives seek on occasion.

Yes, these drives do get warm. Put a fan in front of them if it bothers you.

You will have to have an SAS controller to run these drives. Whether you buy a WS board from ASUS or use a RAID card.
