Jia Xiaobai leads to the fascinating NAS: First, the solid-state hard disk intel Dafa - Intel 600P 256G nvme start logic and out of the box comment
After reading the NAS articles of Aunt Zhang’s home gods, the tide of emotions is not the solution I need. With the digital disk, Niangban's blockade and overbearing deletion of Xiaobai's collection, Xiaobai can only put all the treasures on the mobile hard disk. The mobile hard disk has USB2.0, and the old and new, copy the file. Touching speed and file security and content management are inconvenient. So, formally decided to set up a NAS system to meet their own private storage desire.
Jia Xiaobai is a poor and white type of computer technology, but the desire is like a devil, driving me to start a long way. This series of articles tells how a computer idiot in a non-IT, communications, and networking-related industry is building its own NAS step-by-step, with detailed descriptions of every detail.
The machine does not have a hard disk. Even if you have a nuclear bomb, the display will not light up. . . . Start with the choice of SSDs
First of all, the small white Internet science popular under the current SSD common "interface."
SATA3 interface: The theoretical upper limit is only 6Gbps.
NGFF (M.2) interface: With PCI-E channel, there is enough speed, small footprint, power saving, fast speed, and good capacity. Gen3X4=32Gbps, there are also SATA channels, the speed is SATA3 theoretical speed 6Gbps.
SATA-Express: Two SATA ports combine one small SATA port and also take the PCIE channel, 6Gbps+6Gbps=12Gbps. (There are no related devices in JD. There is an M.2 interface completely replaced by Intel.)
Direct PCI-E: As the name suggests, directly inserted in the PCI-E channel, not suitable for my itx small board flow, generally itx small board has only one PCI-E channel, occupying the video card no place to insert.
Second, talk about the "interface" selection logic . NAS mainly pushes itx or mtx small chassis, and the cramped space in the itx chassis is absolutely a little to save a little space, whether it is to install or save the expansion slot later. In order to connect hard disks to NAS, I initially requested that the motherboard of the ITX must be a 6 SATA port. The purpose is that the 6 SATA port can be used to access the storage tray to maximize the storage space for the expansion. (The last one selected was ASRock Z170 Gaming Itx/ac. , But this motherboard is a bit weird. Two of the SATA are combined into SATA express. If the backplane's M.2 interface is connected to a SATA device, the front 2 SATA port will not be enabled, which means that the two SATA ports will be destroyed. It is better to choose 4SATA ​​products, so the demand determines the next requirement, the best choice for solid state drives is the M.2 interface, and it is a PCI-E channel device, so it does not occupy the onboard 6SATA port expansion capabilities; secondly this M .2 interface in the backplane, to save space; the last way can still early adopters (Jia Xiaobai science before that SSDs are iron box SATA port, after all, Taobao sell more). In one fell swoop, then M.2 interface ~
Finally M.2 interface, the choice of PCI-E channel equipment, there are currently many such devices, such as: Iridium, 950pro, SM951, PM951, SM961, Plextor M8peg, Toshiba XG, and Intel series.
Basically, Jia Xiaobai did not move his head directly into the 600P of a 256G that was historically low-priced. The reason is simple, cheap, and it is still M.2 PCI-E, and the end ~~~
The gods said that TLC particle IQ was anxious. Jia Xiaobai said that the 5-year warranty was the slowest, faster than SATA3, and cheaper than SATA3 high-end SSD. What's enough, in fact, it's mainly cheap. . . . .
Unpacking time below
The oblique seal is used. Once it is opened, the seal will be torn to a strip. After tearing it off, it cannot be restored (to avoid hair dryer Dafa?) to avoid refurbishing the goods.
Here is the family portrait
Because the M.2 card is like a memory stick, the packaging and transportation method is also like a memory strip, and then it is specially stored through five layers of corrugated paper to avoid impact during transportation.
About some friends concern about the warranty issue, on the intel website
Enter the serial number below to check the warranty period and have detailed warranty explanations.
Here's what we love to see:
Because Jia Xiaobai divided the two districts, it can be seen that the system disk running points is slightly lower than the slave disk, but the nominal speed and Intel official propaganda are the same, and at this speed, you compare the other high-end SATA3 on the Internet or Nvme's SSD is faster than SATA3, but it's cheaper; it's definitely slower than high-end nvme, but it's much cheaper.
to sum up:
Advantages: 1. Cheap; 2. Warranty for 5 years; 3. Intel Belief; 4. Performance in the past; 5. Drive is currently win10 default, follow-up with the drive may have potential to be upgraded
Disadvantages: 1. Online said nvme SSD, in win7, 8.1 support is not good, win7 8.1 users should pay attention.
Buy new and not buy old, in the SATA3 become a bottleneck today, m.2 nvme will be a strong rise (more and cheaper prices), the recent installation of a friend suggested that you can consider m.2 support PCIE board.
Group NAS, SSD selection is just a side dish, the following article will talk about the choice of mechanical hard drives, solid state because of the current price and security issues, large-capacity storage is still the data, movies, pictures on the traditional mechanical hard drive Reliable, and how to choose a reliable mechanical hard drive, will be the key to data security and stability!
