Not sure if you guy have seen this but Seagate drives now come with 32mb of cache (500GB upwards) and perpendicular 2nd gen Platters (assume x2 but maybe x4).

Anyone know if this offers true value for money, performance leap over say Hitachi T7K250 SATA2 250GB drives?

At £82 a drive for 500GB version - it's not beyond the realms of economy to raid a pair/Trio of these........ if there really is a benefit?

Yes mate the larger catch should perform better than a drive with a smaller catch size as it is able to hold much more information in the catch, and can store this information in the catch before it is written to the drive.

Personally if you are looking at upgrading to a drive with a larger catch i would pay the extra and go for the Hitachi 750gb drive which is only an extra £20.00 for the extra 250gb's of storage, this could be partitioned in to two or three drives.
 
Thats my thought process too sacha mate - seems to me that the additional cache will certainly help, more so in RAID than as a standalone drive.

The Hitachi unit - although offers a slightly better price per GB, does not have 2nd generation Perpendicular design and only 16mb of cache.

What I am really looking for is raptor (or better) performance at half the price - the seagate unit ticks all the boxes, I guess we will need to see a review before we dive in, at which point a price drop or two will probably occur.
 
Very tempting 2 upgrade.. but I doubt it would help much.

If it turns out it does help ill buy one and sell each of my WD's to my dad/bro and get 2 of those babies.
