HDD v SSD

Sorry, I thought that write/read speeds were pretty similar on HHD's (except raptors, SCSI) and SSD's.

As I have raptors in RAID 0, lets compare the read/write speeds of those with a 64gig OCZ core sata II SSD
 
Depends which Raptors you have; 150GB>74GB>36GB.
Run a benchmark and compare to the specs given on the SSD. For 2 in RAID0 you will probably find that they are faster, however the real power of SSDs is the low seek time. I went from 2 36GB Raptors in RAID0 to an Mtron SSD and have never looked back, it's awesome (and a lot quieter :P)
 
I have two 74gig.
Are the raptors faster in read and write? I thought the SSD's are super fast reading? so its only the seek time they are impressive at?

What hard drive bench mark programmes are there?
 
Damn shame about write cycles though, would be ideal in a NAS, used for torrents..except of course how many times the torrents write to the disc. Probably have to wait for a few years for affordable 1TB SS, perfect for totally silent music NAS server :-)

Looking at velo HD for boot, better value per GB. 30GB with Vista isn't really enough.
 
Basically the original Raptors are no match at all. The VRaptors are closest of the mainstream desktop drives but even they are bested by higher performance SSD's.

But then on the other hand the SSDs are very expensive for the space you get, and the next generation is always around the corner meaning the previous generation will depreciate faster than DFS sofas.
 
HD Tach and HD Tune are the most popular programs for benchmarking conventional hard disks. I would look at the new V2 drives from OCZ if you want a decent boost in performance. Lots of new companies are entering the SSD arena in the next few months so prices should start to drop.
 
All SSD vs. VelociRaptor (VR) tests are not apples against apples comparisons. The VR is 300GB; most SSD available today are a lot smaller in capacity


IF you take a 300GB VR and ONLY partition it to (leaving the unpartitioned portion of the drive un-touched):

- 300GB (full partition for example only) = access time of 4.2ms

- 150GB = access time of 2.1ms (meaning half of the drive is not used)

- 75GB = access time of 1.05ms

- 36GB = access time of .57ms



When you partition only a portion of the drive, the drive will always partition the outer portion (or fastest portion) of the platter first.



Now, if we were to take a VR with 64GB vs. an SSD of 64GB. You will see a completely different outcome.


So with the above analogy, when SSD gets to 300GB, it will be slower too.



People will say “why would I pay for a 300GB VR and only use a portion of it”. Well, if some one is willing to buy SSD today, the 300GB VR is still A LOT cheaper, and if partitioned properly, faster.
