Hmm, Seagates 7200.9 drives aparently have the same data throughput and speed figures(aproximately) then the raptors, but only go at 7200RPM. In my opinion data density, and just general increases in technology that allow lower seek times, higher data bandwidth, but at the same spin speed are the intresting ones. If you can buy a noisy HDD that goes at 10k, or a less noisy equally good one that goes at 7200 which do you buy?
I would not think any other manufacturers would bring out 10k SATA drives, atleast in the short term (aka watch for tomorrow news announcement to prove me wrong!) as the market they directly compete with is the 10k rpm SCSI stuff. WD don't make SCSI drives, so they won't take business from themselves. The other manufacturers, do.
The latest gen of (SATA) drives are pretty damn good in comparison, the raptor is what, 2-3 years old now? When the raptors first appeared, they were amazing, now they are just 'still the best' but the competition is catching up very fast. Soon they won't be the best.
The main trouble is, they are tiny... almost too tiny... not their noise - they are only 0.1 dba louder than a 7200.8 at idle (look on storage review)

According to what source? I am cautiously skeptical. Yes current 7200RPM drives will beat my old Cheetah. And I wouldn't rule out the possibility that future 7.2k drives will beat the current Raptor. But 10k drives (future Raptor) has at least as much, if not more space for improvement.
Looking at benchies of HDs, increased data density may increase the transfer speed slightly, but not decrease the seek time (RPM still affect those the most). I would say that random access is more important than sequential read/write for the average PC use (especially when multitasking).
If the Seagate 7200.9 can best the Raptor overall, then great, I'll be replacing my main drive with something faster, and with several times the capacity. But I'll remain somewhat skeptical. I think there might be some 7.2k drives that compares favorably, if not best the Raptor at sequential write. But thats not what I am interested in (if I valued that highly, I would be running RAID-0).
Edit: Ya, but once 22k drives are released, wouldn't they gradually phase out the 10k SCSI drives in favor of 15k as the mainstream SCSI drives? Seems to be the natural progression to me. The 7200k SCSI drives were gradually phased out too.. I wouldn't expect that to happen in a day, but it seems like the natural progression.

Best speed rating on storage review ATM is the Atlas 15K II which tops out at 97.4MB/s sustained, so SCSI disks are pretty close to the 100MB/s mark.
The top SATA is of course the raptor at 71.8 MB/s, but seagate's top 7.2k disk is barely slower at 69.8. Raptors were never about sequential speed really, if you need that RAID is the better choice. Raptors still thrash any of the 7.2K disks for access times which as people have said, is a significant factor in overall performance, often moreso than raw data throughput.
Raid 0 reduces reliability - if one drive fails yopu lose all the data, so effectively you are halving the MTBF, for a minimal speed increase.
Hmm, MBTF isn't really something I'd use when describing reduced reliability in regards to RAID 0. But obviously it does double your chances of loosing everything, one more reason why it's not all that.
Obciously teh answer is SCSI !
hehe
anyone seen that SCAN have like HUUGE scsi drives now for like £500 squid? Ultra 320 i believe. wowser.
Ultra 320 is the interface bandwidth, not the drive transfer rate ;P
Personally, I would rather the next gen 7.2k RPM drive to have SCSI drive reliability, than Raptor performance.

Never had a reliability problem with any IDE drive (not at home anyway!).
But yes the max theoretical transfer rate at 160 or 320 is not relevant, it's all about latency not brute speed, as with so many things these days with PCs....
Two dead drives to date. And I've only been using IDE for the past.. 4 years? I am surprised the Cheetah I got in 98 is still working. It has seen its share of traveling too (along with that PC). I don't care much about free replacement to be honest (I only buy those with 3 years warranty). The lost data/time is more annoying than anything.
Good luck getting anything with a three year warrenty now, all the manufacturors I can think off have moved to no extra warrenty over the legal UK requirement of one year. The only non SCSI drive I know of that comes with a decent warrenty are the 5 year warrenties on Raptors.
Seagate - 5 year warranty on all drives

Ah, is that so? I must have neglected to check them when I did my spree of drive checking after I found out it wasnt just maxtor doing the 1 year thing. This is very good. I know the only company I'll be bothering with for hard disks from now on then.

You need to give the porn sites a break and hit some computer sites instead.Realistically, you probably wouldn't notice much difference. RAID only really makes the benchmark progs give faster benchmarks, and about a 10% speed increase in everyday tasks
Oh, and how old are the IDE drives, you talking UDMA or what??Even the raptors aren't as great as they used to be, compared to other drives

In the real world seeks is where the game is at and RAID0 does nothing for seek times, if anything seek times will increase with RAID0 due to synchronisation, mixing and matching say two manus might cause added seek times but even then in the real world it'll be barely noticeable on benchmarks.
