Amazon EC2 執行個體存放區
執行個體存放區為執行個體提供暫時的區塊層級儲存空間。這個儲存空間位於實際連接到主機電腦的磁碟上。執行個體儲存體非常適合暫時儲存不斷變更的資訊，例如緩衝區、快取、臨時資料及其他暫存的內容。也可用來存放複製到整個執行個體機群的暫時性資料，例如網頁伺服器的負載平衡集區。
執行個體存放區包含顯示為區塊型儲存設備的一個或多個執行個體存放磁碟區。執行個體存放區的大小和可用裝置的數量，會隨執行個體的類型而有不同。
執行個體存放磁碟區的虛擬裝置為 ephemeral[0-23]。支援一個執行個體存放磁碟區的執行個體類型具有 ephemeral0。支援兩個執行個體存放磁碟區的執行個體類型具有 ephemeral0 和 ephemeral1，以此類推。
執行個體存放區生命週期
您只能在啟動執行個體時，為執行個體指定執行個體存放磁碟區。您不能將執行個體存放磁碟區與某個執行個體中斷連結，然後再連結到不同的執行個體。
執行個體存放區中的資料，只會在相關執行個體的生命週期期間存在。如果執行個體重新啟動 (刻意或無意)，執行個體存放區中的資料仍會持續存在。不過，在下列任何情況中，執行個體存放區中的資料會遺失：
-
底層的磁碟機故障
-
執行個體停止
-
執行個體休眠
-
執行個體終止
因此，如果是高價值的長期資料，請不要只使用一個執行個體存放區，而是使用更持久的資料儲存體，例如 Amazon S3、Amazon EBS 或 Amazon EFS。
當您讓執行個體停止、休眠或終止時，執行個體存放區中的所有儲存區塊都會重設。因此，資料無法透過另一個執行個體的執行個體存放區存取。
如果從執行個體建立 AMI，其執行個體存放磁碟區上的資料不會保留，資料也不會出現在您從 AMI 所啟動執行個體的執行個體存放磁碟區上。
如果您變更執行個體類型，執行個體存放區將不會連接至新的執行個體類型。如需詳細資訊，請參閱 變更執行個體類型。
執行個體存放區磁碟區
執行個體的類型會決定可用的執行個體存放區容量，以及執行個體存放磁碟區所使用的硬體種類。執行個體的使用費包含了執行個體存放磁碟區。您必須指定在啟動執行個體時想要使用的執行個體存放磁碟區 (不包括 NVMe 執行個體存放磁碟區，因為此磁碟區已預設為可用)。然後在使用之前先將執行個體存放磁碟區格式化和掛載。啟動執行個體之後，即無法讓執行個體存放磁碟區變成可用。如需詳細資訊，請參閱 將執行個體存放區磁碟區新增至 EC2 執行個體。
某些執行個體類型使用採行 NVMe 或 SATA 的固態硬碟 (SSD)，來提供高度的隨機 I/O 效能。在需要極低延遲的儲存裝置時，這是一個理想的選項，但您不希望資料在執行個體終止時仍持續存在，或是可以善用容錯架構。如需詳細資訊，請參閱 SSD 執行個體存放區磁碟區。
NVMe 執行個體存放區磁碟區和某些 HDD 執行個體存放區磁碟區上的資料會靜態加密。如需更多詳細資訊，請參閱 Amazon EC2 中的資料保護。

* 除非經過初始化，否則連結至某些執行個體的磁碟區，會承受第一次寫入的效能損失。如需詳細資訊，請參閱使執行個體存放區的磁碟區達到最佳的磁碟效能。
** 如需詳細資訊，請參閱 執行個體存放區磁碟區 TRIM 支援。
c1.medium 和 m1.small執行個體類型也包含 900 MB 的執行個體存放區置換磁碟區 (在開機時可能不會自動啟用)。如需更多詳細資訊，請參閱 執行個體存放區置換磁碟區。
如需查詢執行個體存放區磁碟區的資訊，請使用 AWS CLI
您可以使用 describe-instance-types AWS CLI 命令來顯示執行個體類型的相關資訊，例如其執行個體存放區磁碟區。下列範例顯示具有執行個體存放區磁碟區之所有 R5 執行個體的執行個體儲存體總大小。
aws ec2 describe-instance-types \ --filters "Name=instance-type,Values=r5*" "Name=instance-storage-supported,Values=true" \ --query "InstanceTypes[].[InstanceType, InstanceStorageInfo.TotalSizeInGB]" \ --output table

aws ec2 describe-instance-types \ --filters "Name=instance-type,Values=r5d.4xlarge" \ --query "InstanceTypes[].InstanceStorageInfo"
範例輸出顯示此執行個體類型有兩個 300 GB NVMe SSD 磁碟區，總共有 600 GB 的執行個體儲存體。
