Western Digital Velociraptor 300GB SATA HD

0 thumbs up


At first glance it's clear that the new Western Digital Velociraptor is not your typical 3.5" hard drive.  In fact, it's not really a 3.5" drive at all.



While the WD Velociraptor does have a 3.5" form factor, the actual mechanics are housed in a 2.5" HDA drive with a 15mm z-height, similar to standard notebook hard drives--only taller.  The drive itself is mounted in a what is essentially a large heatsink, that WD has dubbed the IcePAK.  The IcePAK is what allows the WD Velociraptor to be mounted in any standard 3.5" drive bay and, of course, it also helps keep the drive cool.



As you probably surmised, the WD Velociraptor is targeted at performance enthusiasts, workstations, and low-end servers.  Its 300GB capacity comes from a pair of 150GB platters spinning at 10K RPM within the drive mechanism.  Four heads access the platters, and because the platters spin so quickly, and are physically smaller than standard 3.5" drives, the Velociraptor is able to access and transfer data much more quickly than competing offerings.



A visual comparison between the WD Velociraptor and a previous-gen 150GB Raptor reveals almost no similarities, other than their coloring.  And be aware, because the WD Velociraptor is not a standard 3.5" SATA drive, its connectors are not in the same position as other drives.  That makes the Velociraptor incompatible with virtually all external hard drive enclosures, DIY NAS boxes, etc.

 the name alone gets a +1 from me. would be nice if it had 32MB of cache as some other drives more than 2x their size do

I talked to WD about the cache size, and they said it offered little to no benefit, so they kept the buffer at 16MB. Obviously, it didn't hurt performance much!

Maybe it's not needed for 300GB hdd...

Anyways it looks sweet ;)

Wow, that thing flies.  I have a 300GB hard drive now, so I know how to work with that capacity.  But the price is pretty steep.  What I actually payed most attention to in the article was the WD6400AAKS which actually seemed to usually perform inbetween the old Raptor 150 and the new Velociraptor 300.  Considering it's great capacity and relatively low price, I may end up eventually going for that drive when I need more capacity, likely this summer.

Definately an impressive drive... its nice to finally see higher RPM drives break through that 150/160GB barrier thats been around for a few years.

yes very nice indeed. Wish these were out when I got my 150 raptor x's but they do just fine. 35% is a big jump though.

Nice review, Marco. That drive looks pretty crazy...a 2.5" drive in a 3.5" heatsink...very interesting.

Consider it dugg!

I guess this unit will cost insanely much,but it does worth it since it is better than even some SAS drives
