For those that want a capacity beyond all, Boot Daily brought a review of Seagate Barracuda ES.2. This hard drive has no less that 1GB of capacity (sadly, in SI system, since HDD manufacturers like to pretend that 1000 bits is one kilobyte. Actually, it's 1024, but who cares, right?). Nevertheless, this unit has 32MB cache, which is a hefty increase over industry standard (16MB). However, our ideal drive has 8GB of flash memory (for system partition) and 1TB of capacity...
--> 1 GB HDD? Even the SSD have 32 GB at least. I Think you mean 1 TB ?

...This hard drive has no less that 1GB of capacity...

Wow. I remember when I bought a 100MB HD just few years ago for 300€.

Shirley shome mishtake...

Another error: 1 byte is made of 8 bits, 1 kilobyte is 8000 bits or 1000 bytes and 1 kibibyte is 8192 bits or 1024 bytes.

1024 bits is 0.128 of an SI kilobyte, since an SI kilobyte has 1000 bytes of 8 bits each = 8000 bits. Alternatively, its 0.125 of a proper kilobyte (i.e. 1024 bytes or 8 bits each, as god intended...)

There are two errors in the above post.
1) the first time you list the capacity of the Barracuda ES drive it is "GB" instead of "TB".
2) the link to the Scythe Katana 2 review has a space in it between hardware and logic which generates the following URL:

remove the space and the problem is resolved.

Seagate release a 1GB drive model that has 250GB platters? I can only assume that they tried to limit it to a single data track so it would always have a seek time of 0ms.

There is a small error where you say hard drive manufacturers pretend 1000 bits is a kilobyte. 1000 bits IS a kilobyte as it follows the standard SI units. However 1024 bits IS NOT a kilobyte, but instead is called a kibibyte.

1GB should probably read 1TB in regards to the seagate drive..
