No point. Not enough capacity. I'd rather have some huge 1/2TB drives in RAID-0. It's about 30% slower than the Velociraptors, but it probably costs hundreds less and gives you way more capacity.

No... just no. It looks like it beats a Velociraptor in benchmarks that do the same thing over and over. It certainly speeds up boot times, but it really isn't that fast.

Even Seagate's own marketing video for it has glaring flaws.
1) They used an old velociraptor that's way slower than the newer ones, and easily gets beaten by modern 7200RPM drives. (ex: WD 2TB Black)
2) After booting about 20-30 seconds slower, the older slower velociraptor held the gap, finishing roughly that same amount of time after the Momentus XT.

A single 600GB Velociraptor would kick a Momentus XT's butt. (if it had such a thing) Two in RAID would slaughter it. But IMO that's a waste of money.


Heh... marketing videos. I much prefer reviewers like Linus, which often pause mid-demonstration to make it easier to compare between drives.

No - he said he runs Gentoo (Linux) so it's safe to say he means 4GB total.

If he were running Windows, it'd probably be 24-32GB.

LOL a 150GB VelociRaptor for $150? What?

300GB for $150

Find me a 600GB SSD that costs $300 or near it. Yes I do realize SSDs ARE in fact faster, but VelociRaptors in RAID 0 offer better value.

Until SSD drives get way cheaper and more reliable, I'll stick to my WD blacks. they work great for what I do (gaming, and lots of games, and data) I have 2.5TB and I probably need to go out and buy another soon. I might get a SSD for a cache drive (intel SRT), but I want one bigger than the 20GB that intel offers, but I'm not sure atm...

Yeah SSDs may be fast, but they are far from reliable - I would keep my OS on the SSD and all my data on regular drives.
