Why I Bought It
Hahaha! The crappy DRAM-less, non-in-house-NAND SSD “威刚 XPG S11 Lite 1T” that had been tormenting me for over half a year is finally replaced! I’d originally planned to wait for 铠侠 RC20 2T during JD’s Double 11 this year, when it would drop to its all-time low for the second time and then buy it. Unfortunately, SSD prices haven’t come back down yet. If I’d known, I would’ve just bought it during 618 this year and wouldn’t be losing 80+ yuan now… Plus the old SSD couldn’t hold on, and it actually gave out first… Recently, drive dropouts, blue screens, crashes, and data loss have been happening frequently, which greatly affected my daily use and was really frustrating. So when the price was still 80+ yuan above the all-time low, I finally couldn’t resist and bought 铠侠 RC20 2T! And that’s how this article came about. Needless to say, the past half year of use before the replacement was miserable—0E throwing errors and losing data every day was a real pain…
The Old Drive
Over three thousand 0E is truly outrageous… even fiercer than Samsung!
It comes with a built-in heatsink shroud, single-sided chip design, and the overall looks are decent—but looks are all it has. Because of the single-sided design, it’s a bit thinner than those with chips on both sides…
Unboxing the New Drive
JD offers 30-day price protection and 7-day no-reason returns, and I stacked a few coupons on top—not bad, though the price… well, you know how it is.
The outer packaging is standard, nothing flashy.
Because it’s single-sided, it’s fairly thin, which is nice—if you’re not worried about heat, you can even add a copper heatsink and install it in a laptop…
I have way too much software and study material data, and I couldn’t be bothered to reinstall the system, so I just used DiskGenius to migrate the data from the old SSD, then did an over-the-top install of the system to fill in the missing files. Woohoo~
Basic Specs
It’s been a while since I bought the new SSD from JD. After all, it’s an entry-level drive with in-house TLC NAND, a Pcie3.0 mid-speed SSD, and the overall experience is fine—at least it has a cache. Due to the “1,000 on the drive = 1,024 in the system” issue, the actual capacity is a bit less than the rated capacity. I bought the 2TB version, and it actually shows 1.81TB.
SSD Testing
Overall it’s fine. I’ll see after using it for a while whether it 0E. That said, RC20 failures seem pretty rare—most failures are caused by the user’s own doing… MB/s 每秒传输速度 is standard, iops 每秒读写次数 is okay, and the file benchmark 100GB performs fine, matching mid-speed Pcie3.0. After all, I don’t have a need to copy large files 24/7; stability is my top priority. Game loading generally depends on 4K随机读写 fragmented files and doesn’t care much about an SSD’s peak speed. Under normal circumstances, the gap between entry-level and top-tier SSDs is less than 2s, so personally I don’t think it’s necessary to spend more money on Pcie4.0. Stability, no data loss, and no 0E errors come first. After all, Kioxia’s predecessor is Toshiba, so stability and compatibility are pretty good… Why not buy a bulk-shipped MLC drive whose endurance crushes TLC? Heh, it’s been hammered by enterprises for so long—even if the NAND isn’t dead, the controller is on its last legs, and bulk-shipped goods have no official warranty. Of course, I can’t speak for anyone’s preferences or tastes, so forget it—I’m going for stability, hehe~~
