SSD hard drives vs SATA drives vs NVMe.What is the difference between SATA and NVMe hard drives?管理
You’re talking about hard drives. These devices are where all the data on your computer exists, from the operating system files that govern your device to the important work document that you can’t lose. You want to make sure that you have the right hard drive for whatever you’re trying to do.SSD hard drives
SSD hard drives SaT, SSD and NVMe are the three main types of hard drives. In this article, we will learn about the different types of people. Whether you are buying a new PC or upgrading, this should help you decide which one to buy.
What is a hard drive, and why do I need it?
The hard drive is the main component of a computer. The term “hard drive” is often abbreviated to “HDD”. You might want to buy one of these:
I think you’re running out of space on your HDD. I need a bigger one.
It takes a long time to open documents or to export large files.
If you’re building a new computer from scratch, what will you do?
Whatever the situation, understanding why you want or need a new drive will help you know what you want and need. Once you’ve got that figured out, it’s time to know more about the different types of hard drives and the trade – offs between them.
SaTATA (Serial Advanced Technology Attachment) is the standard interface for most desktop and laptop hard drives. They are rotary hard drives with spinning platters and a needle that writes data to consecutive sectors on each platter. Compared to their predecessor, the PATA hard drive, SATA can write at a speed of 6 Gb/s and 600 MB of throughput to the disk.
A single drive can range from 500 GB to 16 TB. These are good drives if you don’t need a lot of storage. If data is written to a disk, it can become fragmented and slow down the system. They are also a poor choice for laptops due to the large number of moving parts in each drive.
Large disk sizes
It’s not good for laptops.
Requires regular de fragmentation.
SSD hard drives
Solid state drive. These disks have no moving parts. The data is stored on non-volatile flash memory instead. They are significantly faster than SATA drives because there is no needle to read or write data. Even the lower performing drives are comparable to SATA drives, but it’s difficult to find an exact speed. n nThese drives are more expensive and don’t come in as many sizes. SsD drives are about 2 — 4 times the price of a SATA hard drive. （SSD hard drives）These drives are designed specifically for laptops, and have no moving parts, making them ideal for storage on the go
More durable, especially for laptops
More expensive than SATA drives
Lower disk sizes
Non – volatile memory express (NVMe) is a type of SSD that is attached to the PCIe (PCI Express) slot on the main board. These slots were originally designed for graphics cards. With a throughput of 3.9 GB/s, the interface rate on NVMe drives can reach 32 Gbps. This can be very useful if you are using a large amount of disk space.
There are some drawbacks to NVMes. They’re available only on desktop computers and very expensive. To use it to its full potential, you’ll want to install your operating system on it. At this time, most BIOS don’t support NVMe. It’s possible to get one, but it could mean replacing the entire main board.
Fastest disk type on the market
Available for desktop PCs only
May require replacing main board to get full benefit
Which is better: SATA, SSD or NVMe?
When deciding between components, there are a lot of considerations. Choose what fits your budget, capacity and technical requirements. The guidelines below may help, and while they won’t fit every situation, they may be useful for planning your next build.
I need a large amount of storage.
They are on a tight budget.
I need a general purpose hard disk.
What is the best way to upgrade a laptop?
Need fast storage under 2TB
Building a high – end workstation or gaming PC
I don’t have a budget.
Building a server that is gonna host an application.
It’s worth mentioning that PCs typically support several hard drives at a time. Where you save files will determine whether you get the performance you want. For example, a common configuration for PCs that render video is to use a faster drive like an SSD or NVMe to run video rendering software (Camtasia, Adobe Premier, etc.) and then transfer the finished product to a cheaper, larger SATA drive.
Build your knowledge and skills.
Now that you’ve learned the basics of hard drives, you should be able to make an informed decision. What are the reasons behind replacing your hard drive? If you apply what you’ve learned here, your hard drive buying experience will be much easier.
