Phase-in of Advanced Format drives There is no set cut-over date for the introduction of Advanced Format drives into new HP Business Notebook or Desktop PCs, or Retail POS systems; instead, drives will be phased in, as shown in Table 4. Note the following caveats: While Advanced Format drives - HP HDX X18T-1200 | Preparing Advanced Format hard drives for Microsoft Windows i - Page 12

; for example, a BIOS update would be required for every system. Moreover, some operating systems do not support booting to 4-KB native drives. Older applications and games would not be able to run, while there would be no performance advantage for a customer.

small sector size constrains storage capacity and has also caused manufacturing capabilities to reach a limit. Under the sponsorship and support of the International Disk Drive Equipment and Materials Association (IDEMA), manufacturers of industry-standard HDDs are transitioning from 512-byte - HP HDX X18T-1200 | Preparing Advanced Format hard drives for Microsoft Windows i - Page 16
In both scenarios, the drive reads the data from the media, modifies the old data with the new data and then rewrites the modified data to the media. Depending on the rotational speed of the drive, this could add 16 - 22 milliseconds to a write. Read performance is not impacted; the drive reads the - HP HDX X18T-1200 | Preparing Advanced Format hard drives for Microsoft Windows i - Page 17
