Because of the epidemic, now are mobile office-based, recently or found that the previous mobile hard disk transmission speed is getting slower and slower, wood usually to form, PPT and other data files (but the database is relatively large, often about 20M table), some high-definition files as a supplement (about 10G / about), laptop is very early to use nvme + sata dual solid-state configuration, but the lack of a transit transmission of media, and finally consider the use of hard disk box + Sata solid state way (more cost-effective, DIY is also convenient), I chose the sata solid state is Taiwan electric stable shadow 512GB, start for the milk tea home, the final single to hand 260 yuan, with the Type-C box 29 yuan less than 300.
In fact, the development of SATA solid state to today has been very mature, which is also a point that wood currently considers, although the nvme solid state speed is fast, the supporting mobile hard disk box is not cheap, but the transmission requirements are relatively more stringent, this time the starting desk electric stable film capacity is 512GB, the highest it also has 1TB equipped.
Another is the problem of Tlc particles, most of the current Sata solid state is Tlc particles, mlc is really gone, and Tlc technology with 3D Nano technology can achieve higher density of storage capacity, this point is not to be expanded here.
Unpacking is not long-winded, the design of 512GB gray of The TAIWAN POWERHOUSE is easy to think of as a metal material, but it is actually plastic, but the texture is quite good. In fact, metal or plastic is not much different, metal shell on SATA hard disk heat dissipation does not have a great advantage, because SATA hard disk is basically not very hot, and replaced by a plastic shell effectively reduces the cost. The plastic shell warranty sticker does not have a screw design, and the hard disk is a snap-on closure scheme, which is easy to pry open with the card.
Taipower steady shadow 512GB of the main control from deyi, the model is YS9082HP, this master control may be relatively unfamiliar to everyone, the company is located in Shenzhen, several more critical parameters listed, support SATA3.2 protocol, 3D MLC / TLC / QLC NAND Flash, sequential write speed: 510 MB / s (YS9085 / YS9082HP) / 450 MB / s (YS9082HC), Taipower steady shadow 512GB this piece of YS9082HP belongs to a sata product line of the relatively high-end model, other parameters from the official website screenshot a figure, everyone is interested in it can understand.
Taipower steady shadow 512GB PCB board is relatively small, and did not join the cache, but the particles are provided 4 (two positive and negative), the model is 29F01T2ALCQK1220947, each 128GB together constitutes a capacity of 512GB, to say that at this price can also enter the solid state of the original granules, Taipower is still more conscientious.
It is also worth saying that the warranty of 512GB of Taiwan Electric Steady Shadow is 3 years, the warranty write volume is 200TBW, if the daily write volume is 20G, it can probably be written for about 29 years, at that time it is estimated that the sata interface has become an antique, and there is no anxiety about what service life (of course, the TLC hard disk used for nearly 5 years many years and did not see any problems)
First use the software to run a score, Taipower Steady Shadow 512GB in the AS SSD benchmark score of 698 points, read and write to 498MB/S and 457MB/S, the better place is that the 4K random read and write can reach 129MB/S and 278MB/S, as an entry-level SATA SSD, this data is normal, if the random access time can be improved, the score will be higher.
The IOP's test also saw that the main control random read and write of this domestic one can reach 33236iops and 71377iops similar to the nominal value.
This time, the 512GB of Taiwan Electric Stable Shadow was directly partitioned, and the read and write speed could reach 552MB/S and 498MB/S, and the random read and write of 4K was 128MB/S and 185MB/S.
ATTO data is more intuitive, Taipower steady shadow 512GB in the 8kb data block has been close to 300MB / S read and write performance, more than 16kb data blocks can reach 400MB / S and more than 500MB / S read and write data, thanks to the blessing of the original factory particles, the stability performance is still good.
In the actual transmission, wood will also be Taiwanese power steady shadow 512GB and the traditional 3.0 original hard disk (a large factory) compared, taiwan power steady shadow 512GB of reading and writing can be stably maintained at a speed of 350MB / S (taking into account the box transmission, protocol bottleneck, etc., and the theoretical value of the difference), and the traditional USB3.0 original mobile hard disk The highest transmission is only at a speed of 80MB / S, such a speed increase is quite obvious.
To sum up, more than 200 prices can start the original granular SATA SSD, which has been upgraded to NVME wood is quite important, daily use although SATA solid state has not been as important as before when the system disk, but in fact as nvme solid state and mechanical hard disk between SATA SSD or there is still a need, as an intermediate medium, it has quite a good read and write speed, as a daily staging is more reliable, of course, If it is to upgrade the SATA solid state to do the system disk compared to the ordinary mechanical disk also has more speed advantages.
