server and PC differences in many aspects: CPU type and quantity, main version, bus system, network performance, disk storage performance, memory system, cooling system, operating system, etc., server scalability, availability, Manageability and availability are unmatched by general PCs. Since the development of IT technology, few people have confused the difference between Server and PC. So what is the difference between a server hard disk and a normal PC hard disk? The server requires 24x7 uninterrupted service, and the hard disk demand is of course the faster and more durable. The PC will shut down because it is not used in general, so it is not necessary to ask for it. The most critical point is the RAID array implemented on the server. Different hard disk companies have developed different technologies to allow RAID to handle hard disk errors. For example, Western Digital is the first to develop Time-Limited Error Recovery (TLER), while Seagate uses Error Recovery. Control (ERC), Samsung and Hitachi use Command Completion Time Limit (CCTL). If you put this Server hard disk on your PC, you can use it as long as the motherboard supports it. As for speed, bandwidth, capacity, MTBF (Mean Time Between Failures), SATA/SAS/SCII, etc., just consider the choice of hard disk, but to choose whether to use it on the server, it depends on the RAID support specifications. Simply put, the difference between Server and PC is reflected in product features, product quality, and product brand.
Function
The hard disk used by Server may be less functional. Most of the new functions will be used for test products or civilian devices, because the enterprise considers not only new features or performance, but most cases are stable. The most important thing is that the server-class hard disk function is relatively old. Quality
In terms of hard drives, Servers are really better, because enterprise services usually do not stop, and the amount of data processed may not be just a single machine. Server hard drives are also looking for third-party OEMs, but the production line may be different, the materials used are different, the number will be more durable. Brand
I think this is the most important thing. PCs can also use SCSI or SAS hard drives, and even cheaper than Server. Why buy a server hard drive? Most of the hard disks used by Server and Storage are listed (of course, the OEMs may still be those OEMs). The firmware has also been changed. You can't change the civilians. But in the same situation, if the server has a problem, the host and the hard disk. And the parts are all the same brand, of course, there must be some protection, but if you buy the A brand host today, use the hard disk bought by the big store, if the data is damaged, who is it? The important part of the hard disk is not the hardware part. The comparison function between Server and PC is not very important. Many enterprises that have no money use PCs. The question is how much the enterprise can tolerate data loss. The biggest difference is based on enterprise service risk and quality considerations.
