RE: Raptor SATA drives - 10/7/2005 10:38:08
The transfer trate is much higher/faster (150) but I would only get the 10,000 RPM Raptors as anything less just doesn't justify the ROI of the added expense for SATA. Keep in mind though new mother boards will most lily have only one IDE connector (read optical drive).
IMHO,
Brian

Raptor vs 15k rpm drives
What makes the raptor so great, is the low seek time. Last week I learned quite a bit about the raptor, I wasn't sure if it would be best to spend the money on raptors, or get the new seagate drives in a raid 0, or get SCSI drives. The seagates were decent, imo good enough for the average person, the SCSI were way too expensive, and the raptors were perfect, except for lacking space. You will notice a large performance gain when switching from IDE to SATA 150. The raptors have even a larger gain when comparing them to the standard sata drives. Is it needed? Just depends on how thick your wallet is. You might be better off with upgrading your CPU, dunno.
I'm just putting together a new computer with 4 raptors in raid 0+1 for 138 GB of total space, and redundancy. Going to be using the dual core x2 4400+ (since it is so quick in business apps).
The raptors are down to around $155 now, which is a killer deal on an awesome drive.
I would suggest grabbing the WD SecureConnect cable to ensure the cable never comes off.
Also, here is a review on the raptor, which apparently was beat by the new Seagate > http://www.anandtech.com/storage/showdoc.aspx?i=2396&p=14
I don't think Anand knows hard drives well (a lot of people on the forums didn't agree with that benchmark).
There have been a few instances of an 80GB raptor, with the same speed and reliability as the 74gb, just with another 6gb of space. (Apparently Dell is shipping them in some systems, only place I have seen them for sale is on eBay).

It doesnt matter how they perform, as long as it sounds cool ;-)

Just to help with your decision:
Tom's Hardware Harddrive Roundup
And if I may say so, the Raptor is one butt-kicking piece of hardware. The only issue you may end up having is the 74 gb of space on it.

there any issues/problems running 2 Raptors together as your OS drive for maximum speed/performance from them? Any input welcome here on this please. :)
- The only issue you will have is if a drive dies, however these are rated at more than 1 million hours MTBF. Depending on your MB, you might want to grab a 3rd raptor and setup raid5. Raid 5 will sometimes slow down performance if you don't have your own raid card. (I'm not too familiar with how much of a slow down, but I have heard it can be around 10%)
You shouldn't worry too much if you have decent fans taking care of the heat. Antec cases are pretty nice, but you will have to provide a link if you want specific info on THAT case (in terms of cooling).
What PSU have you thought about using?
I ran a raptor next to a wd 250gb for 6 months, I had zero issues with heat. You can get a really low cost fan/temp controller that will let you know of temp issues.

According to the specs, that PSU should be perfectly fine for what you need. What video card are you thinking about? My 6600GT requires 18A on the +12V rail, which is quite a bit.
Doubt this will be of help to you, but ZZF has your PSU for $80. If they ship to the UK, it might be cheaper than if you purchased it locally.
My AX500-A is powering an X2 4400+, 4 X 512MB DDR400, 4 raptors in raid (all bootup at same time), 2 250gb WD (also in raid), a 6600GT, sound card, and two BenQ DW1640s with zero problems.
My knowledge of PSUs is very limiting. I am just starting to learn about PSUs, so don't quote this stuff. Most of this is what I have learned two weeks ago when I was doing my research before building my new computer. There doesn't appear to be too many PSU experts on here, my thread has gone unanswered for awhile. Dan seems to know hardware pretty good, hopefully he will notice this thread.
Also, a lot of Intel lovers have switched over to server boards simply because they compete better with the AMD chips. Depending on your budget, it might be something to look into.
For hard drives, the most stress is put on your +5V rail, which is what can cause hard drive failures if your PSU cannot supply enough power. Some people do something called staggered startup (where the drives startup in a delayed order), however, since you are using raid, there is not way you can do a staggered startup.
With only two raptors, you shouldn't have any issues at all. If you decide to run 7800GTX in SLI, then you might think about spending a bit more in terms of a PSU.
