Vultr Block Storage VPS 종류(SSD vs SATA)에 따른 속도 비교

Vultr Block Storage VPS 종류(SSD vs SATA)에 따른  속도 비교

Vultr VPS 의 종류에는 Compute Instance (SSD) 와 Storage Instance (SATA) 두 종류가 있는데

Block Storage 를 지원하는 Region 인 뉴저지에 VPS 개설해서 테스트 해 보았다.

▶ Storage Instance (SATA)

[root@vultr-st-nj ~]# mkdir /mnt/bs1

[root@vultr-st-nj ~]# echo /dev/vdb1 /mnt/bs1 ext4 defaults,noatime 0 0 >> /etc/fstab

[root@vultr-st-nj ~]# mount /mnt/bs1

[root@vultr-st-nj ~]# dd if=/dev/zero of=/mnt/bs1/1GB.bin bs=100M count=10

10+0 records in

10+0 records out

1048576000 bytes (1.0 GB) copied, 9.21985 s, 114 MB/s

[root@vultr-st-nj ~]# hdparm -Tt /dev/vdb

/dev/vdb:

 Timing cached reads:   11350 MB in  2.00 seconds = 5678.78 MB/sec

 Timing buffered disk reads: 366 MB in  3.02 seconds = 121.00 MB/sec

121.00 MB/s 속도가 나왔다.

▶ Compute Instance (SSD)

[root@vultr-sd-nj ~]# mkdir /mnt/bs1

[root@vultr-sd-nj ~]# echo /dev/vdb1 /mnt/bs1 ext4 defaults,noatime 0 0 >> /etc/fstab

[root@vultr-sd-nj ~]# mount /mnt/bs1

[root@vultr-sd-nj ~]# ls -l /mnt/bs1

total 1024020

-rw-r--r-- 1 root root 1048576000 May 17 13:27 1GB.bin

drwx------ 2 root root      16384 May 17 13:24 lost+found

[root@vultr-sd-nj ~]# dd if=/dev/zero of=/mnt/bs1/1GB.tmp bs=100M count=10

10+0 records in

10+0 records out

1048576000 bytes (1.0 GB) copied, 4.04785 s, 259 MB/s

[root@vultr-sd-nj ~]# hdparm -Tt /dev/vdb

/dev/vdb:

 Timing cached reads:   21342 MB in  2.00 seconds = 10683.04 MB/sec

 Timing buffered disk reads: 730 MB in  3.00 seconds = 243.10 MB/sec

243.10 MB/s 속도가 나온다.

똑같은 Block Storage 인데 마운트 된 서버가 뭐냐에 따라 속도가 다르게 측정 되다니~

VPS 시스템의 특징일지도 모르겠다.

블록스토리지 마운트 방법은 여기를 https://ivps.tistory.com/57 참고하자.
