For an external usb hard drive attached to a computer, which is more suitable: a writethrough cache or a block cache

Charra [1.4K]

Disk access is way slower than memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which reduces disk accesses time. Here a portion of disk is bought to cache for reading and a modified blocks are first changed in cache but reflected in the disk at one go. On the other hand with write through caching each modified block is written to cache and at the same time it is written to the disk. Write- through caching requires more disk I/O so they can have a negative effect on the performance.

Sorting data is an integral part of data analysis. You might want to arrange a list of names in alphabetical order, compile a list of product inventory levels from highest to lowest, or order rows by colors or icons. Sorting data helps you quickly visualize and understand your data better, organize and find the data that you want, and ultimately make more effective decisions.

You can sort data by text (A to Z or Z to A), numbers (smallest to largest or largest to smallest), and dates and times (oldest to newest and newest to oldest) in one or more columns. You can also sort by a custom list you create (such as Large, Medium, and Small) or by format, including cell color, font color, or icon set.

Notes:

To find the top or bottom values in a range of cells or table, such as the top 10 grades or the bottom 5 sales amounts, use AutoFilter or conditional formatting.

For more information, see Filter data in an Excel table or range, and Apply conditional formatting in Excel .
