Intel SSD 問題

想問下
1) Intel 40G SSD x 2 行 Raid 0
2) 一隻 Intel 80G SSD

install OS & Applications
以上2個 case 在平時運行邊個會快些?  分別大不大?

Thx!

如果你onboard raid 好的話 Intel 40G SSD x 2 行 Raid 0 會快

如果onboard raid 唔得, 一隻 Intel 80G SSD

當然系2) 一隻 Intel 80G SSD

咁點解一隻 80G SSD 會快過 40G 行 raid 呢?

For IOPS, single 80G will be faster, for sequential read speed, 40G RAID 0 is faster... for 4k r/w, single 80G will be faster.

so conclusion is using single 80G is better for OS and applications and noted that RAID 0 doesn't support TRIM as well.

p.s. I am using 80G RAID 0
