In the current SSD market, mainstream users will choose SATA 6Gbps interface hard drives, and the price is cheap and sufficient. Performance-oriented players will prefer M.2 hard drives, NVMe.
In many M.2 hard drives, especially the M.2 2280 specification is the most common. Toshiba storage recently introduced an M, 2 2242 NVMe hard drive, which is not only small in size, but also comparable to other M.2 hard drives. It is also very characteristic.
Why is Toshiba Storage RC100 so special?
First look at the official specifications:
The RC100 SSD supports the NVMe 1.2 specification, but it uses the PCI-E 3.0 x2 channel, so performance is not as prominent as other M.2 drives.
120GB version read, write speed is 1350MB/s*, 700MB/s* (data from Toshiba test environment), 240GB version is 1600MB/s*, 1050MB/s* (data from Toshiba test environment), the best is 480GB version, but the reading and writing is only 1600MB/s*, 1100MB/s* (data from Toshiba test environment).
Its special feature is first of all small size, The M.2 2242 specification means that the length is 42mm. Compared to the common M.2 2280 hard disk, the length is only half of the latter. , as shown in the following figure:
Halving the length is more practical for notebook users, which means taking up less notebook space. For desktop users, the small size is just a icing on the cake, but Toshiba Storage Design to reduce volume is the key to RC100.
To reduce PCB footprint, Toshiba Storage RC100 SSD is Single chip package , Toshiba storage encapsulates the master, NAND flash chip on a single chip , Ultra-high integration brings a smaller PCB footprint.
Whether it is 120G or 240GB or even 480GB, it can be realized with only one chip. The common M.2 hard drive, 240GB hard drive is usually 2-4 flash chips.
Higher integration also reduces the power consumption of the RC100 series SSDs. Standby 0.5 mW, typical power consumption is only 3.2W The typical conventional M.2 SSD consumes more than 5W or more. This advantage is more attractive for notebook users and can extend battery life.
Due to the use of a single-chip package, there are almost no redundant components on the PCB, and the official model has not been announced.
As for the flash chip, Toshiba Storage RC100 240GB SSD uses Toshiba storage itself 64-layer stack 3D TLC flash memory, based on BiCS 3 technology, has been widely used in many SSD hard drives As the original NAND flash memory of Toshiba storage, Toshiba storage RC100 240GB SSD reliability, quality control is still very secure.
Toshiba storage RC100 240GB SSD performance test
In the Diskspeed Test, Toshiba storage RC100 240GB SSD read speed of 1333MB / s, write speed of 825MB / s, performance is slightly lower than the official indicator.
In the Txbench test, the read and write speeds of the Toshiba storage RC100 240GB SSD are 1605 MB/s and 1054 MB/s, respectively, which is similar to the official nominal performance.
In the AS SSD Bnechmark test, Toshiba's storage RC100 240GB SSD read and write speed is 1423MB / s, 864MB / s, 4K random read 31.8MB / s, this performance is relatively more general.
After switching to IOPS performance, 4K reads 8148 IOPS, 4K randomly writes 34061 IOPS, and the performance is more general.
Performance test summary:
Because it is a PCIe 3.0 x2 channel, the Toshiba storage RC100 240GB hard drive is obviously not a high-performance M.2 hard drive. The random performance is average, but the read can still reach 1600MB/s, and the write can reach 1GB/s. It is twice as high as the average SATA hard drive.
Toshiba storage RC100 240GB SSD temperature test
How is the heat generated by Toshiba storage RC100 240GB SSD? The result of the software detection is probably 74°C under high load We then did the actual test with an infrared thermometer. The results are as follows:
The infrared test temperature is about 77 °C, which is similar to the software monitoring result. Considering the high integration of the RC100 hard disk, the heat dissipation space is limited, and there is no separate heat sink. This temperature is acceptable.
to sum up:
If you only look at specifications, performance and other indicators, Toshiba storage RC100 240GB SSD is actually nothing special.
Based on NVM, e 1.2 and PCIe 3.0 x2 channels, it is an M.2 hard disk with excellent performance, read speed, write speed up to 1600MB/s, 1000MB/s, but only in M.2 hard disk. This level is only normal, excellent but not alone.
The biggest advantage of Toshiba storage RC100 240GB SSD is its Ultra high integration , The single-chip package allows the PCB area to be significantly reduced, requiring only the M.2 2242 specification.
Compared to ordinary M.2 hard drives Half short, while power consumption is also greatly reduced This advantage is not significant in desktop SSDs, but it is used in It is very obvious to upgrade the notebook.
Ultra-small size, lower power consumption and excellent performance, players who need to upgrade their notebooks can First consider Toshiba storage RC100 240GB SSD.
