Frågan, av :stefan:
Jag letar ny burk och farsgubben har fått en offert som verkar lite intressant. Den kommer användas till surf, en del grafik, mp3makande och -spelande, filmtittande, bränning osv.

Läs frågan i sin helhet →Jag håller med om att 8 MB cache på hårddiskar är något av en hype, men det ger ju faktiskt lite bättre prestanda. Skulle i så fall vilja påstå att det är mer hype att till samma dator köpa ett 3com-kort.

I believe there are two main reasons for this dramatic increase in buffer sizes. The first is that memory prices have dropped precipitously over the last few years. With the cost of memory only about $1 per MiB today, it doesn't cost much to increase the amount the manufacturers put into their drives. The second is related to marketing: hard disk purchasers have a perception that doubling or quadrupling the size of the buffer will have a great impact on the performance of the hardware.
The size of the disk's cache is important to its overall impact in improving the performance of the system, for the same reason that adding system memory will improve system performance, and why increasing the system cache will improve performance as well. However, the attention that the size of the hard disk buffer is getting today is largely unwarranted. It has become yet another "magic number" of the hardware world that is tossed around too loosely and overemphasized by salespeople.
