I have long wanted to have a compact storage of all personal files, which you can always carry with them, and use on different computers to work directly on this store without copying the information onto discs computers.
The first experiment with a 128-gigabyte memory stick ended in failure - the flash drive in this mode not live six months (apparently, flash drives are not designed for multiple overwriting files).
A year ago, I started thinking about the SSD external drive and found that the Chinese manufacturer of SSD-drives KingDian just released a small external hard drive, 240 gigabyte version which I obzavolsya the beginning 2018.
The gray box is a self drive and a 24-santimtrovy cable USB 3.0 - USB Type C.
On the box label with a single parameter - "240G". Everything that is written to the storage "KingDian Portable SSD 240GB". At the end of the connector USB Type C. We drive there is a blue status LED, which lights up when the drive is enabled and blinks when there is a read or write, but it is very strange - in the case. One can see it only through the gap between the housing and the connector, and only at a certain angle.
The connector includes a drive not to end - 2.2 mm its metal parts remain visible.
For the first time I meet an external drive that is sold untagged. I'm afraid of this, many customers may think that the drive is faulty, because the user interface Windows, it is not visible.
After partitioning and formatting the drive volume is 240 024 693 888 bytes or 223 GB.
I tested the drive speed on two different computers with USB 3.0 interface. read and write speed of 300 MB / s, which is the external drive is very cool.
Test AS SSD Benchmark showed even better results.
When connected to a USB 2.0 to read and write speed of 40 MB / s.
But this is only a test. To check the actual speed I measured the copying of files of different types.
First I copied from another SSD-drive on the 156 video files, the total volume of 25,688,898,317 bytes (sequential read speed of the other SSD-drive about 470 MB / s). the copy operation took 127 seconds, its speed was about 202 MB / sec. Read these files in 96 seconds, the reading speed of about 267 MB / s.
In the second test I copied from another SSD 8150 photos total volume of 15,127,553,931 bytes. Recording took 187 seconds, the recording speed was about 81 MB / s. Reading took 151 seconds, the reading speed of about 100 MB / s.
During operation, the drive housing is heated, but not much - up to 38 degrees at the front and 40 degrees to the rear.
In idle mode, the drive consumes 0.16A, in read-only mode 0.23 A, 0.26A in recording mode.
Compared with an external hard drive external SSD-drive has several advantages:
- not afraid of falls and bumps;
- fast;
- little;
- Silent;
- consumes little.
Compared with high-speed USB-stick also has advantages:
- is not afraid of a large number of overwriting files;
- fast;
- not heated.
Previously SSD-drives were very expensive, but now the price is not "bite" and a small external SSD-drive it is possible to afford. External SSD-drive KingDian Portable SSD is available in three versions - 120 GB for $ 37, 240 GB for $ 53.66 and a 500 GB for $ 79.79.
Actively use this drive for over a year and is very happy with it.
P.S. Now Aliexpress valid promotion code SHOPNEW, giving a discount of $ 3 at the order of $ 20.
In addition to the mobile application Aliexpress handing out coupons $ 2 from $ 15, and the basket of mobile applications two coupons of $ 5 from $ 25. Perhaps now distribute.
In addition, if you buy any product (even for $ 0.01) give the three coupons: $ 2 off $ 18 $ 3 $ 25 $ 6 and $ 48.
