Yangtze Memory Technology Company (YMTC), China's ambitious new memory manufacturer specializing in NAND flash, launched the first client-segment SSDs under its own brand, the PC005 Active series and the SC001 Active series. Rumors of YMTC developing its own brand SSDs surfaced first in June. Prior to that in May, it was reported that Phison could add support for YMTC NAND flash chips to variants of its existing SSD controllers, and so it's highly likely that the new YMTC SSDs use Phison-sourced controllers. Interestingly, the company deployed its first-generation Xtracking 64-layer 3D TLC NAND flash chips instead of its 2nd generation 128-layer QLC chips.

The PC005 Active comes in the M.2-2280 form-factor with PCI-Express 3.0 x4 host interface, leveraging the NVMe 1.3 protocol. The drive is available in 1 TB. 512 GB, and 256 GB capacities. All three variants read sequentially at speeds of up to 3,500 MB/s, wiring at up to 2,900 MB/s, up to 2,500 MB/s, and up to 1,200 MB/s, respectively. Their endurance is rated at 640 TBW for the 1 TB version, 320 TBW for the 512 GB, and 200 TBW for the 256 GB variant. All three are backed by 5-year warranties.

The SC001 Active drives come in 2.5-inch form-factor with SATA 6 Gbps interface, coming in the same 1 TB, 512 GB, and 256 GB capacities. All three read at up to 520 MB/s, and up to 510 MB/s writes. Interestingly their endurance is rated higher, with 680 TBW for the 1 TB variant, 370 TBW for the 512 GB variant, and 170 TBW for the 256 GB variant. The three are backed by 3-year warranties. As for availability, YMTC will target its home market of China first, and since it is a beneficiary of the Chinese government's ambitious "3-5-2 plan," it's first buyers could be Chinese state institutions. Chinese retailer JD.com listed the PC005 Active 512 GB for the equivalent of $77 and its 256 GB variant for $54. The SC001 variants are priced at the equivalent of $123 for the 1 TB variant, $67 for the 512 GB variant, and $42 for the 256 GB variant.

When are drive makers going to get it through their heads - no one cares about this anymore, it's time to start making affordable higher capacity drives to phase out spinning rust.

The problem with SSD at current is that they are still very expensive per TB.

There are basically two schools of thought.

#1 Buy a small (cheap) SSD (250GB - 500GB) and use it to run the OS while leaving everything else to secondary peripheral drives

#2 Spend more money and buy a larger SSD (1TB - 2TB) and use it to run the OS, cloud storage services (Onedrive, icLoud, etc) and leave everything else to secondary drives.

#3 Spend a LOT OF MONEY on a 4TB or 8TB SSD and be able to fit virtually everything on one drive.

I personally like Option 3 because I like having everything in one place and easier to backup to a HDD if necessary.

8TB SSD from Micron and Samsung are under $1000 with 4TB models under $700.

At the rate we are going, we may hit 8TB SSD in 5 years for $500 or a 10TBSSD under $1000.

My entire data collection would fit perfectly on a single 8TB SSD, but it's hard for most people justifying dropping $1000 on a toy like that.

No, they really aren't. You can easly find 1 TB SSDs for about 100$, hell I even got an NVME one for 120$. Plus, few people even need more than 1-2 TB.

And that's still too expensive to me for anything other than my host drive. The amount of storage you need for common things like games and media has been steadily going up and up. A single TB drive won't hold more than 15 to 20 AAA games these days, and 4K movies are becoming the standard. In order to handle those kinds of storage needs, you either have to pay way too much, or still fall back on mechanical storage. I have a 512GB SSD host drive and another 512GB SSD for my games, and everything else is still being stored on HDD because for the price of the cheapest bottom of the barrel 1 TB SATA SSD, (which isn't a good idea to buy anyway) you can get 4TB of reliable HDD storage and still have money left over for a six pack and a pizza.
