Photo belated. Lenovo Legion Y90 gaming smartphone - why do you need RAID 0?

A couple of days ago, a gaming smartphone Lenovo Legion Y90 (original name - 联想拯救者Y90电竞手机) was announced in distant China.

In principle, everything is quite traditional. The most powerful iron, super-sophisticated cooling system with a pair of fans, super screen, super battery, weak cameras. But there is one thing that cannot be ignored. And that thing is RAID, more specifically, RAID 0. A thing that the average person, in principle, does not need to know about. Although it is entertaining.

Lenovo Legion Y90 comes in three variations. 12+256GB, 16+256 GB and 18+640 GB. Pay attention to the last strange number, 640 GB? Why is that? Because in reality there is not one "memory", but two. In addition to the "standard" 512 GB of smartphone permanent memory, another separate physical "disk" of 128 GB has been added. Why?

The fact is that even with the transition from old spinning hard disk drives (HDDs) to modern storage devices such as those used in smartphones, it is "disk" operations (i.e., operations with permanent memory) that still remain the bottleneck , the slowest place. The essence of RAID 0 is thatthen blocks of information are written one by one to several media (in this case, two). And, accordingly, they are read in turn. Those. disks run in parallel. Which, when reading and writing significant amounts of information, gives a considerable gain.

About more mundane things.

The fastest chipset, Qualcomm Snapdragon 8 Gen 1. We are waiting for about a million points in AnTuTu.

The screen is huge, 6.92". AMOLED-matrix with a refresh rate of up to 144 Hz and a sensor polling rate as much as 720 Hz. The resolution is standard, 1080x2460 (388 ppi). The absence of cutouts is noteworthy. �Instead of biting off a piece of the screen, we made the top edge a little wider and sent the front camera there.

The rear cameras (64 + 13 MP) were also treated a little unconventionally. They were placed almost in the center of the rear side of the smartphone, next to the logo. (And the logo here is not simple, but with multi-color backlighting, wow!)

There is no exact information about the sensors used in the cameras. It seems to be the main thing here OmniVision OV64A, but this is inaccurate.

Not every gaming smartphone is equipped with a good battery, but they were not stingy here. 5600 mAh And h�The row, of course, is ultra-fast, 68 W.

Other. There is NFC, 5G, a fingerprint scanner built into the screen, two (!) USBs, loud stereo speakers. No standard audio output and no support for memory cards.

And about prices. ¥3999 (₽65400, $634), ¥4299 (₽70300, $681) and ¥4999 (₽81800, $792) for 12+256, 16+256 and 18+640 GB respectively.
