Nowadays, SSD hard disk has become a necessity for players to install, and most of the new products are of m.2 specification, and SATA hard disk is becoming less and less. This time, Western Digital has not forgotten the old users, and launched a new blue disk SSD - blue sa510 series, with a capacity of 250GB and a maximum capacity of 1TB, which has cut 2TB and 4tb compared with the old blue disk SSD.
Blue sa510 series hard disk actually has m.2 version, but it also has SATA version. Both of them are based on SATA 6gbps protocol, so there is no difference in performance. The reading speed is 560mb / s and the writing speed is up to 520mb / s, which is the limit level of SATA.
In terms of write life, the 250GB version is 100tbw, the 500GB version is 200tbw, and the 1TB version is 400tbw. The warranty is 5 years
The power consumption of the 2W series and the blue series are not much different from that of the blue series, but the power consumption of the blue series is much better than that of the blue 510 series**
In addition, Western Digital has not released the flash memory and master control information of blue sa510 series. QLC flash memory may be the largest. However, the positioning of this generation of blue disk is not high. 2TB and 4tb high-capacity products have been cut off, which is suitable for upgrading the old platform. Don't tangle with the type of flash memory.
In terms of price, 250GB, 500GB and 1TB versions are about 65, 75 and 100 dollars respectively, that is to say, the 1TB version is about 630 yuan, of course, the price of BOC will rise a little, maybe to 699 or even early 700.
