The MyDigitalSSD BP4 is an interesting SSD. The Phison S8 when released several months ago was a nice mainstream offering, but the new programming and firmware puts the Bullet Proof in a new category. The performance offered isn't at Vector or 840 Pro levels, but it isn't too far behind, at least right out of the box. When the BP4 has data on it the performance decreases quite a bit, but that still higher than what we consider for a true low-end, ultra-budget SSD.
So, that really leads us to the interesting part. I hate to use it, but it fits so well. The BP4 raises the bar of what a mainstream SSD is. The price is what we once considered budget, lower than mainstream, but the performance is higher than what we once classified at mainstream.
This is a revolution in the mainstream market. Normally we only get excited about this sort of thing happening in the ultra performance side where Vector and the 840 Pro play, but I'm excited. Until now it was business as usual for mainstream, as we saw just days ago with the SanDisk Ultra Plus. The 256GB Ultra Plus sells for around $210, but the BP4 240GB is only $180, and it's faster.
When it comes to the 120GB capacity size, things get even more interesting. The current push is to reduce the number of NAND flash chips in these lower capacity models. 128GB is the new 60GB while at the same time 512GB is the new 256GB... with 1TB just around the corner to displace 512GB. BP4 didn't fall into the cookie cutter pattern and retains the proven method of sixteen NAND flash chips working together to keep performance high.
Going into the review, we thought a sixteen NAND solution would draw more power than the new four and eight chip designs, but that wasn't the case. BP4 offers the lowest idle and in-use power consumption numbers we've published to date from the drives we've tested so far.
The MyDigitalSSD BP4 120GB is available today for $99.99 at Amazon and MyDigitalDiscount.com. It offers best in class battery life, impressive performance and is stable out of the box.
