我这个是固态硬盘还是机械硬盘？

（750gb/7200转/分）
我有更好的答案
机械硬盘固态硬盘没有机械运动结构，所以也没有“转速”这个参数，有转速的都是机械硬盘。
那我这个硬盘容量算大吗？算好吗？
750G算比较大了，7200转也是主流。固态硬盘的主流还是500G以下，虽然性能更好，而且价格比这个750G的贵几倍。够用就好。

机械硬盘。固态硬盘没有转速的。
那我这个硬盘容量算大吗？算好吗？
容量不算大，现在一般买1T的硬盘，性价比更好点。
那7200转算好吗？
7200转算好的，现在的台式机硬盘基本都是7200转的。笔记本硬盘是5400转。还有什么问题一次说完。

Power-Efficient, High Performance SSDs Optimized for Cloud Storage
The Intel SSD DC P4501 cloud-inspired SSD is built with an entirely new NVMe controller, optimized for read intensive workloads and designed to maximize CPU utilization. With the Intel SSD DC P4501 Series, data centers can increase users, add more services, and perform more workloads per server. Now you can store more and know more.
Manageability to Maximize IT Efficiency
Intel SSD DC P4501 drives are built to maximize IT efficiency within existing server footprints. New firmware manageability features - including improved firmware updates, health monitoring, and secure erase - help reduce server downtime through improved update processes and expanded monitoring capabilities. In addition, the Intel SSD DC P4501 is platform-compatible with Intel Volume Management Device (Intel VMD) which delivers seamless management of PCIe-based NVMe SSDs and enables enhanced serviceability and hot-plug to minimize service interruptions during drive swaps.
SMART management and Intel custom log pages provide advanced drive telemetry to manage thermals, monitor endurance, and track drive health status. Management coverage is now expanded across a wider range of drive states with support for the NVM Express Management Interface (NVMe-MI) specification, an industry standard way to manage the SSD out-of-band.
