I'm building a music making rig and was wondering if it's worth splashing out on a velociraptor HD. I may be recording up to 36 tracks of hi-def audio and need a fast HD.

I've used 2 x 'Raptors in RAID the past on a gaming rig and whilst the performance gain was blinding, I feel personally using them for audio (HD or otherwise) is overkill.Quote:

HTH.
If you're recording with Mic's you may wish to consider that 'raptors are significantly louder than standard HDDs, so may not be ideal.
SSDs seem to be the way forward for this kind of usage.
Generally not any more. If price is a concern then a high platter density drive is better value. If price isn't a concern then SSDs give much better performance.Quote:

Velociraptors are quieter than the 150gb Raptors, which in turn are far, far quieter than the old 76gb Raptors, which were quieter than the 36gb ones. Even in a quiet environment they're not at all bad. Unless you've got the mic next to the case, I doubt they'd be picked up at all.Quote:

I disagree. An Indilinx or Intel based SSD has a sequential (2MB) read of 241-262MB/s. A WD VelociRaptor manages 121MB/s, with the Seagate Momemtus clocking only 78MB/s (figures taken from Anandtech's review). That's measuring the SSD's in a used state as well.Quote:

Once you look at random reads and writes SSD's completely destroy the performance of mechanical drives. RAID? Have you seen the RAID test on YouTube? SSD's in RAID make mechanical drives look like floppy disks. Remember, SSD's don't suffer from fragmentation issues and with TRIM, the new versus used performance degradation is arguably insignificant.
A mechanical drive is better than a SSD in one main area only, price or bang for buck. If you do any kind of multitasking then the (much) faster random read/write from SSD's will be VERY noticeable. So it all comes down to whether the additional performance offered by a SSD is worth it for the OP.
I'd recommend looking at a decent 1TB hard drive first. In most cases they'll have a minimum transfer rate sufficient for your purposes.Quote:

While it might indicate the trend, a 2MB file represents zero use to any media producer.Quote:

Thanks for all the fascinating info. From what I gather then, SSDs are the future for random access intensive applications like OS's and will soon make anything else obsolete performance-wise. For sequential read/write applications such as audio recording it would seem that regular mechanical drives still provide enough speed and vast amounts of space at the best price. Looks like the raptors are somewhat surplus to anyone's requirements. Thanks again.
A 2MB sequential write in this scenario is a test of "large" block writes. The figure is fairly indicative of 2MB or 300MB writes. It's not just a single "2MB write".Quote:

Yes, I realised it was repeated thanks. ;)Quote:

Sorry, but that's not the best example to pick - a Vertex Turbo is severely overpriced. If we're talking about a competitor, how about the Intel G2, £340 for just over half the capacity of the Velociraptor.Quote:

Sorry for stating the obvious :). For a sustained read or write the cache on the SSD and mechanical HDD would become saturated over time and thus plateau any measurements. The numbers I quoted were averages I believe, so spikes have probably been taken into account. In theory a heavily fragmented HDD would perform worse as would a relatively full SDD with TRIM status pending.Quote:

The G2 is slower than a Velociraptor at sequential writes. I picked the Vertex Turbo as it seemed fairly even in both reads and writes without being at the top of the class (in that test, the Vertex EX is top (other than the Intel X25e 64gb drive)).Quote:

I dont know enough about professional audio recording any more, so can you tell me - I assume this is to create a master? So we're not compressing to CD standards, for example?Quote:

36 tracks - unless you are wanting to record 36 tracks simultaneously (are you?) then any modern hard drive is fine, even 2.5" 'laptop' type drives.
Probably a good rule of thumb however, as was always the case in the past, is have one drive for your OS, and a second drive to record your data, just to prevent any mis-haps. We used to recommend the second drive going on a seperate IDE channel, however SATA connections are all individual, so you're quite safe there.
