Better performing SATA 3.0 HDD's than the VelociRaptor?

post #1 of 9
Thread Starter 
I know VelociRaptors have been out for a long while now and have always been considered a high performing HDD.

I'm in the process of building a new pc but am looking for some HDD info - are the VelociRaptors still the #1 performing drives to go with for SATA 3.0 or are there newer SATA 3 HDDs out that can out perform the VelociRaptors now?

Well,

This is a really generic question... Why aren't you going with an SSD? If you have that sort of money then SSD with a nice storage drive would be the way to go.

Even then, with the cost fo the raptor you'd still be better off going with a Momentus XT or even a Samsung F3 1TB raid0 stripe with 2 drives.

Honestly, for the price you're paying for, just go with a 60gb SSD and be done with it. Might have around half of the storage for the same price but the performance more than makes up for it.

SSD is out of the question due to their small size and high price. This drive will be used in a ESXi lab and will house 4-5 virtual machines. 20-30GB per virtual machine and a SSD is quickly filled up.

VelociRaptors are probably the biggest high performance HDDs out there.

I suggest making a RAID0 of F3s or Seagate Enterprise series.

You still will be running a host OS and that would benefit from a SSD.

The VMs could just access a 2xRAID0 1TB array since they will be network bottleneck in terms of latency anyway.


Performance HDDs are simply not worth it anymore. You pay 50-300% more per GB but only get a few percentage in performance.

The motherboard I'm using (SuperMicro) has onboard USB so I will be installing ESXi on a 4GB thumb drive - which is over kill considering a 1GB drive would work too.

I agree and that's why I'm asking. The two drives I'm looking at is Western Digital Caviar Black WD5002AALX (which runs about $70) and the Western Digital VelociRaptor WD3000HLFS (which runs about $150). PassMark actually shows the Caviar Black getting a better score than the Raptor but I'm sure the SATA 6.0 has a lot to do with that as well.

My big concern was not to have a very slow SATA drive in there if spending that extra $50 or so would make it that much faster.

SATA 6Gb/s has nothing to do with the performance difference.

Performance is based upon rotation speed, areal density, platter count, cache, and firmware.

Is the Samsung F3 1TB on the chart? These go for around $55 and perform well.


What is PassMark criteria? I would probably look at webserver or database performance charts.... these are more reflective of multiple user disk access.

Also most SSD's don't really use the full bandwidth of SATAII let alone a mechanical drive on SATAIII
