1500 rpm hard drive

hey everyone,
i've been googling my arse off this past week but to no avail, i need help on finding a 1500rpm internal hard drive (got my heart set on it!), about a 100gb-150gb, if anyone can point me in the right direction i would be very thankful. i rekon my system would realy improve by replacing my current western digital which is making a strange noise everytime i access anything on it.

i have
1 UDMA ATA 100/66/33 connector
Serial ATA
2 IEEE1394 connectors
the 1500rpm drives i can find use a different SCSI or the serial attatched SCSI , so here lies the problem, can i use the connections i have on my motherboard to attatch the SCSI, perhaps an adapter??
i was considering a solid state drive or the i-drive -as in Scan's website- but i read somewhere that they are unreliable in retreiving data at times and can actually loose everything on the drive when switched on and off....
...i dunno, any suggestions guys ?

you mean 15,000rpm right?

Does a digital camera, flash besed mp3 player or your phone loose all it's data when switched off? no, and nor will Solid State Disks as they use Flash memory. The only one that would is one based on DRAM, but they ahve a battery backup and mirror to an internal laptop drive anyway.

You will need a SCSI or SAS controller to use one of those drives. You are talking a lot of money.

These things aren't designed for desktop situations. They are for servers or high performance workstations.

What is the rest of your system spec? you may find that any extra performance in the disk is pointless if the rest of your system isn't up to it.

Those are targeted for servers. As funkstar pointed out an SSD (Solid State Drive) will work, although they are just getting to hard drive performance. For "normal" usage the only really option in uselessly fast harddrives is the Raptor, however this costs 3-4x the cost of a 7200 RPM harddrive.

I'm not really sure exactly what you do with you system or what its specs are, but I would guess the best performance benefit would come from more ram or a video card upgrade.

If you do feel a need to upgrade you harddrive anyways there are three paths. The simplest would be to get a Raptor. The second would be to use two normal harddrives in a RAID array, this will increase bandwidth, but unless you have full hardware RAID will create more work for the CPU. The third path is an SSD, which will decrease latency to well below that of 15000 RPM drives, but will be very expensive per gigabyte and comes only in small size.

Yea I'd go for a 10k Raptor. Having said that, the new 7200rpm drives are matching them for constant speed (the high density ones) so whether it's worth it is kinda up in the air. SCSI drives are notoriously complicated to set up.

Get a solid state drive if you fancy something a bit different, your data should be safe :)

I heard also SSD are slower in some respects to normal drives. It's either random access times or constant read/writes. But I can't remember which :)

Samsung's latest gen are the first ones that exceed normal HDD transfer rates.

15,000 rpm drives run very hot, not something I'd want in my pc case. We use oodles of these at work and have to be very careful about the build up of heat from them.

On the SSD issue it was originally (have not been looking at reviews on the newest and greatest) that they are faster at random access (as you would expect with no moving parts) but that linear read/write speeds were lower.

Well, it does depend how much you'll be willing to pay. The MTRON can do 90MB/sec sustained (along with the fast random access). Though it's still short of the fastest SCSI drive in the outer edge, or even the latest Samsung F1 for that matter, the average sequential transfer rate is competitive with all the others. Still, at $1500 at the time Anand tested it, it's not for everyone.

About the rest of the system being up for it, I think it depends what it's used for. It's certainly not going to add to the FPS of any game, but there are definitely applications that can benefit from a faster HD even with just a mid-range PC. Still, I recommend that the OP looks into SCSI a little more - it's not really that hard to set up, but I am wondering if he is miscalculating the costs/benefit of such setup.

To answer the question, the Seagate Cheetah 15K.5, the Maxtor Atlas 15K II (if you can find it) are some of the fastest drive around especially for server use. But the Raptor is not necessarily slower for desktop use (there are instances its faster).

Well given I our 73GB 15,000rpm drives from HP came with a ~3200 price tag and weren't available in larger sizes you'd be mad to put one of these in your PC IMO :)

I'd spend the money on a new 1TB disk running at @7200 rpm, personally. Fast as a Raptor 150 GB (apart from seek latency), and a whole lot more space.

Why isn't there a update to the Raptor yet? Jesus, it can't be hard to slap in a higher density platter.

The access times are the most important bit for standard use on a OS drive, but you're right - Raptors don't give the boost to make up for the negatives. Not even slightly. I still have 6 of them mind. :D

Guy, you cannot be serious.

i use a seagate 15,000 but its SAS (serial attached scsi) the drive is connected to a SAS controller

dabs.com - Seagate Cheetah 15K.4 73GB U320 SAS (ST373455SS)
£113 for 73GB

Computer hardware and software at amazing prices, available online from Scan Computers UK
£84 for controller ( pci-x or pci ) single drive will max the pci slot but i use pci-x

expensive for what it is but i need full duplex
