我想對 SSD(可能使用加密檔案系統)進行基準測試,並將其與 Windows 上 crystaldiskmark 完成的基準測試進行比較。
那麼我該如何測量與 crystaldiskmark 大致相同的東西呢?
對於第一行(Seq)我想我可以做類似的事情
LC_ALL=C dd if=/dev/zero of=tempfile bs=1M count=1024 conv=fdatasync,notrunc
sudo su -c "echo 3 > /proc/sys/vm/drop_caches"
LC_ALL=C dd if=tempfile of=/dev/null bs=1M count=1024
但我不確定參數dd
。
對於隨機 512KB、4KB、4KB(佇列深度=32)讀/寫速度測試,我不知道如何在 Linux 中重現測量結果?那我該怎麼做呢?
對於測試閱讀速度之類的東西sudo hdparm -Tt /dev/sda
對我來說似乎沒有意義,因為我想要對諸如encfs
安裝之類的東西進行基準測試。

也許我應該寫一些關於這個問題的動機:我正在嘗試對我的固態硬碟進行基準測試並比較一些加密解決方案。但這是另一個問題(在我的系統上對不同加密解決方案進行基準測試的最佳方法)。在網路上瀏覽 SSD 和基準測試的資訊時,我經常看到用戶在論壇中發布他們的 CrystelDiskMark 結果。所以這是這個問題的唯一動機。我只想在linux上做同樣的事情。有關我的特定基準測試,請參閱我的其他問題。
答案1
我會說菲奧產生這些工作負載不會有任何問題。請注意,儘管它的名稱為 CrystalDiskMark,但它實際上是特定磁碟上檔案系統的基準測試 - 它不能單獨對磁碟進行原始 I/O。因此,它總是會產生檔案系統開銷(不一定是壞事,但需要注意,例如因為被比較的檔案系統可能不相同)。
一個基於複製上面螢幕截圖中的輸出並補充了來自以下內容的資訊的範例CrystalDiskMark 手冊(這並不完整,但應該給出總體思路):
fio --loops=5 --size=1000m --filename=/mnt/fs/fiotest.tmp --stonewall --ioengine=libaio --direct=1 \
--name=Seqread --bs=1m --rw=read \
--name=Seqwrite --bs=1m --rw=write \
--name=512Kread --bs=512k --rw=randread \
--name=512Kwrite --bs=512k --rw=randwrite \
--name=4kQD32read --bs=4k --iodepth=32 --rw=randread \
--name=4kQD32write --bs=4k --iodepth=32 --rw=randwrite
rm -f /mnt/fs/fiotest.tmp
當心- 這個例子永久破壞 中的資料/mnt/fs/fiotest.tmp
!

答案2
原答案:https://unix.stackexchange.com/revisions/480191/12
我創建了一個腳本,嘗試使用fio 複製crystaldiskmark 6 的行為,並且我還添加了對舊測試(如512kb 測試)的支持,這個答案在我最初創建它之後很長一段時間才更新,該腳本有很多需要改進的地方。為使用早期版本的使用者提供了更改日誌。
該腳本取決於菲奧和df。如果您沒有或想要安裝 df,腳本應該仍然可以工作。該腳本與破折號相容(如果您想使用破折號將 #!/bin/bash 更改為 #!/bin/dash),但請注意,對於破折號,不支援使用讀取命令自動完成(因此您必須如果使用破折號,請逐個字母拼出您要測試的位置的路徑)。
這是完整的腳本:
#!/bin/bash

#Changelog #
#############################################################################################################
#Added prompts for user input to configure script instead of relying on hardcoded settings.
#Added a lot of errorchecking
#The script is now optionally compatible with dash (this is the reason for there being a sed command at the end of every echo -e instance, dash liked to print the -e part when I was testing.)
#Vastly improved compatibility across distributions
#Special thanks to everyone who contributed here: https://gist.github.com/i3v/99f8ef6c757a5b8e9046b8a47f3a9d5b
#Also extra special thanks to BAGELreflex on github for this: https://gist.github.com/BAGELreflex/c04e7a25d64e989cbd9376a9134b8f6d it made a huge difference to this improved version.
#Added optimizations for 512k and 4k tests (they now use QSIZE instead of SIZE, it makes these tests a lot faster and doesn't affect accuracy much, assuming SIZE is appropriately configured for your drive.)
#Added option to not use legacy (512k and Q1T1 Seq R/W tests) to save time when testing.
#Ensured the script can run fine without df installed now. Some information may be missing but worst case scenario it'll just look ugly.
#Added a save results option that imitates the saved results from crystaldiskmark; the formatting is a little wonky but it checks out. Great for comparing results between operating systems.
#Reconfigured results to use MegaBytes instead of MebiBytes (This is what crystaldiskmark uses so results should now be marginally closer).
#Sequential read/write results (512k, q1t1 seq and q32t1 seq) will now appear as soon as they're finished and can be viewed while the 4k tests are running.
#Note: The legacy test option defaults to no if nothing is selected, the result saving defaults to yes. It's easy to change if you don't like this.
#Observation: When testing, I observed that the read results seemed mostly consistent with the results I got from crystaldiskmark on windows, however there's something off with the write results.
#Sorry for the messy code :)

這是將這些檔案與同一磁碟機的 3 個基準進行比較的影像,其中 1 個使用 crystaldiskmark,2 個使用腳本:
當您執行腳本時,它會要求您配置它(選項包括:目標目錄、循環、大小、寫零和舊版測試),如果您不輸入任何內容,每個設定都有預設值。要測試特定的硬碟,您需要先安裝它,然後在詢問您要測試哪個驅動器的提示中鍵入該硬碟上目錄的完整路徑。運行腳本時,會在目標目錄中建立隱藏的臨時文件,並在運行完成後將其清除。即使您在進程運行時使用 CTRL+C 取消該進程,它仍然應該清理檔案。
測試結果分兩個階段顯示:順序和 4KB,順序讀/寫測試先完成,完成後在 4KB 測試運行時顯示。如果您在測試完成之前取消該過程,則退出時將顯示任何部分結果。
請注意,有時您可能會得到稍微偏離的結果,特別是如果您在測試運行時在背景執行某些操作,因此建議連續執行兩次測試來比較結果。
這些測試可能需要很長時間才能運行(儘管在新版本的腳本中得到了顯著改進)。目前腳本中的預設設定適用於常規 (SATA) SSD。
不同驅動器類型的建議大小設定:
- (SATA) SSD:1024(預設)
- (任意)硬碟:256
- (高階 NVME)SSD:4096
- (中低階 M.2/NVME)SSD:2048
高階NVME 通常約2GB/s 的讀取速度(例如英特爾傲騰和三星960 EVO;但在後者的情況下,由於4kb 速度較慢,我建議使用2048。),中低端的讀取速度可以介於兩者之間讀取速度約為 500-1800MB/s。
在新版本的腳本中,4KB 和 512KB 測試將顯著加快,因為它們不再使用使用者定義的實際完整大小。 (Crystaldiskmark 也會減少 4KB 測試的大小,否則永遠會花很長時間)。
已知的問題:
- 用於選擇測試硬碟的路徑中不能有空格。
- 如果你問我的話,那些 ntfs-3g 基準測試看起來非常可疑。
現在你就得到了它。享受!
答案3
嘗試K磁碟標記,與 CrystalDiskmark 非常相似。
該應用程式是用 C++ 和 Qt 編寫的沒有任何KDE 相依性。
用法
首先,選擇一個資料夾(以及可選的其他參數)後,按一下All
。
安裝
基於 Ubuntu 的發行版
sudo add-apt-repository ppa:jonmagon/kdiskmark
sudo apt update
sudo apt install kdiskmark
基於 Arch 的發行版
KDiskMark 包含在官方社群儲存庫中。您可以像安裝任何其他軟體包一樣安裝它:
sudo pacman -Syu kdiskmark
開發版本可以從 AUR kdiskmark-git 套件安裝。
git clone https://aur.archlinux.org/kdiskmark-git.git
cd kdiskmark-git
makepkg -si
軟呢帽
KDiskMark 包含在官方 Fedora 儲存庫中。您可以像安裝任何其他軟體包一樣安裝它:
sudo dnf install kdiskmark
openSUSE 風滾草
sudo zypper install kdiskmark
答案4
它可能與 CrystalDiskMark 不完全相同,但它的優點在於它支援的平台:
控制台應用程式(Linux、Windows 和 MacOS - .NET Core 3)和跨平台類別庫(C#、.NET Standard 2),用於測量磁碟/儲存裝置的讀取/寫入速度。
該項目還支援 Android,如其上所列GitHub 專案頁面。
