Size SSD saya 120GB. SSD semakin cepat jika sizenya semakin besar.
Secara teoritis, Speed SSD INTEL S3500 itu 135MB.

Sequential Read 445 MB/s
Sequential Write 135 MB/s
Jadi speed sekarang adalah wajar.

"Reducing the number of partitions wouldn't really help much, as far as I'm aware, and would not be supported, as it would make a significant change in the server's structure. If you're looking to improve performance, caching as much data into system memory (RAM) as possible would make the most impact in improving load speeds."
