Velociraptor in raid0

[ted34]

Just got a new 300gb velociraptor and been offerred another one. Currently run a seagate 7200.10 320gb for O/S.

Basically how much improvement will i see by switching to the v-raptor and how much improvement again by getting 2 v-raptors in raid0. Is it worth another £145

Also how loud are these over the seagates? Not too fussed when seeking but more when idle and im trying to sleep.

how much improvement again by getting 2 v-raptors in raid0.

Depends on what you do, compression and decompression times would be improved, video editing wouldn't benefit though, loading times aren't improved by raid either because access times are the bottleneck.

Will probably be a lot noisier. My old Raptor RAID 0 chirps away like a budgie.

Video work would be sped up that's what 64K-256K Stripes are aimed at.

If you just use for normal all round use then 16K-32K is the one for you.

Loading times will be improved in some games but not as much as years ago due to better coded games.

Seeks are factor but 2xVRaptors still Seek faster than most if not all 7.2K HDD's.

VRaptors are not as loud as Raptor 8MB's or Raptor 16MB's.

Vraptors are pretty quiet. Nothing like the 150Gb Raptors. Cant hear mine. Can hear a slight seek, but rarely. (Mine is bungeed)

lies

loading time sin raid are better im faster at loading into games than my mate with 1 valcirapotor

I work with benchmarks rather than anecdotal evidence.

Even though a hard drives avg transfer rate may be 80MB/s, it doesn't achieve anything like that when loading applications because it has to seek for the files on the hard rather than perform a linear read. Hence doubling the bandwidth with raid 0 doesn't improve performance because it can still only transfer files as fast as it can find them, which is no faster than before as files are split accross both hard drives. Hence why games load faster on ssds than raptors even if they have lower throughputs.

Raid0 is faster overall, I go by real use not benches (same for 3DMARK Ho's).

Anandtech have been known to talk Tosh in the past.

I can't agree with any of the above you posted but wont call you a liar like the peep above.

You keep saying that despite the fact that a benchmark measuring how long a game and windows takes to load is real use. And that fact that I posted 3 different websites, not just anandtech, do you think there is some conspiracy against raid0? I really wish it did improve loading times as my scsi array is in raid0, but alas it doesn't.

Does for me.

As most GOOD reviews will show, games do not all benefit, some do and some don't, and they do tell you games are better coded these days to reduce load times.

I don't use Raid0 for the above reason, its faster overall in my multi use of my PC.
