Storage Solutions Hitachi Deskstar 7K1000 (1 Terabyte) HDD review

[thexfactor]

Finally the first proper review is out ... waiting for a comparo between this and the samsung and seagate 1TB drives

The terabyte race for consumer desktop hard drives has been on for a long time, now the first generation of drives is here. On April 25th, Hitachi announced that it would begin shipping the Deskstar 7K1000, their latest series of consumer hard drives, weighting in at 750GB and a monstrous 1000GB (1TB). The 1TB version which we are reviewing today is slated at $399, a serious price tag for this colossal amount of storage.

The Deskstar 7K1000 represents a milestone for Hitachi and for the hard drive industry as a whole, as it is the first drive to offer a 1 terabyte capacity. However, Hitachi has not simply grabbed five 200GB platters and stuck them together to create a 1TB hard drive. Rather, there is much more to the Deskstar 7K1000, such as its Serial ATA II interface and the massive 32MB memory buffer. This is also the first desktop Hitachi drive to feature PMR technology (Perpendicular Magnetic Recording).

Can someone give me a coherent explanation as to why the buffer size (32MB) increases with the capacity ?

Something more than just less waiting for things to happen..thx

Uh yeah man, its just like the difference between the 1mb>2mb>4mb cache on the processor.

the higher the Cache the more the proc could fetch data instead of seeking too much on the disk itself there by increasing the data rate, though this may not be evident in ordinary applications once we go for gameplay or playing hd movies and other HDD demanding stuff u can see the diff clearly.

I can see the point with the CPU, since instructions take a minimal amount of space. But what about data on a HD, can be lots bigger, in the 100s of MBs.

Disk->cache->RAM

How does a 32MB cache help there ?

If you are reading a big file at some point the cache won't be able to keep up anymore.

I guess i'm saying isnt the cache a little bit on the small side compared to what i might have to read ?
