公司的09年老macbook,换了SSD,用Blackmagic Disk Speed Test测试,写速度只有60M
TRIM已开启
brew install gptfdisk
sudo gdisk /dev/disk0
结果如下
GPT fdisk (gdisk) version 0.8.10
Warning: Devices opened with shared lock will not have their
partition table automatically reloaded!
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Command (? for help): p
Disk /dev/disk0: 117231408 sectors, 55.9 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 305C3774-31A0-4BBC-966C-F6DF1490ED6B
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 117231374
Partitions will be aligned on 8-sector boundaries
Total free space is 13 sectors (6.5 KiB)
Number Start (sector) End (sector) Size Code Name
1 40 409639 200.0 MiB EF00 EFI System Partition
2 409640 115961831 55.1 GiB AF00 MacSsd
3 115961832 117231367 619.9 MiB AB00 Recovery HD
装系统时,在磁盘工具的分区标签的分区布局是选择一个分区,难道这样操作错了?
