SCSI vs SATA

[Stone]

Has anybody here used both SCSI and SATA for HDD's?
Being a mechanical rather than electronic device the HDD is the slowest component in a PC. I have seen now on eBay there are plenty of ex-workstation and ex-server Ultra-320 SCSI HDD's available. Granted they are small capacity by todays standards (usually 18 to 36GB) and that is why they have been replaced and sold on eBay, but they are pretty cheap. I have seen 10k and 15k RPM HDD's selling for between 15 to 40 euro.

I was thinking of buying two of these HDD's and a PCI Ultra-320 SCSI card. I would use one for my Windows Disk and another for my Linux disk (and having my swap partition on a 15k RPM HDD would be a huge boost).

My question though, is has anybody seen from experience that the WD Raptor as fast or faster than the SCSI 10k/15k RPM? If so I would may rather buy a single Raptor HDD and partition that as it might be more cost effective.

sorry for the grave digging, but have you read up on the new perpendicular HDs? I'm running two 400g seagates...perpendicular technology.

gives you a tech hard on, but the price.......

fibre is definitely the way to go if you have the money, but as far as scsi or sata? go sata...damn near the same speed, more capacity, cheaper per gig, and much more reliable...hell, even servers are using hot-swappable satas now instead of scsi. scsi is still faster, but...sata is catching up.

but like I said, if you got the money, go fibre.

Interesting! The price of that 300GB drive isn't much more than a Raptor and it's double the size! The seek time is also amazing! I've heard of fibre, never used it or seen it though. Is it expensive? Does it use PCI-E? I have a free PCI, PCI-E x1 and PCI-E x4 slot. What's compatability like with a Core 2 Duo and Asus P5B-DLX Wifi? Does it need additional power? I have a 700W PSU so the power itself shouldn't be a problem but what type of connecter does it need if any?

Raptors arn't worth the money in my opinion if you are planning on storing files. I'd say only use a raptor if you are maybe offline gaming and want some fast load times. I have a 320gb SATA 16mb cashe and 7200rpm seagate and it does fine. They're only about 100 bucks canadian too.

alot of questions stone...I'll try and answer them to the best of my knowledge.

1. yes
2. no
3. should be compatible with the proc, but the board may be a problem...it takes a FC-SCA connector instead of IDE, SATA, or SCSI...it's a 40 pin connector...and I think it stands for fibre channel single connection adaptor....
4. same power, 700w would easily cover it...

until the price drops on the fibre, I'd still go with sata. I've had a few scsi drives crap out on me, but so far not one sata. but if you got the cash, there's also solid state...I forgot about that.

Forget about Solid State for now. What I meant about PCI-E was that I know fibre doesn't work with IDE or SATA so I'd abviously need an expansion card. PCI would be pretty slow to run two of those HDD's off at once.

I need really fast storage. I have over 1TB in regular disks, but for the work I do I need faster HDD's.

I have a pretty fast computer, Core 2 Duo E6300 oc'd stable to 2.94Ghz (yeah, faster than the ?950 Core 2 EE), 2GB of Ballistix DDR2-5300 oc'd to 800Mhz (4-3-3-12) and the P5B-DLX is a great board (except for the sound which is absolute shit, but I have a discreet SB for games and have an external Digidesign MBox2 for my pro audio work). I do alot of graphic, video, 3D animation and audio work so I want the fastest HDD possible, especially for a swap partition and scratch.

hmmmm...I haven't heard of a pci card for this yet...but I'll do some research and get back to you.

[Stone]

Thanks, I had a look, but all I have come across are PCI-X cards.

all I've been able to find are nic cards....
