Trancend releases High durability M.2 SSD adopting SLC mode with 100.000 rewrites

It has been a topic of discussion by many, MLC, TLC, QLC but the holy grail in relation to endurance still is SLC written NAND, that however is expensive. Well, Trancend is thinking outside the box and is releasing an M.2 SSD that is written 100% SLC.

The number of data rewrites is 100,000 times, which is about 32 times higher than your average "BiCS4" product. In addition, quality has been improved by producing high-quality FGT DRAM cache manufactured by major manufacturers and manufacturing at our own factory in Taiwan. Ideal for applications with high writing frequency, such as servers, medical equipment, monitoring systems, and terminals. The capacity lineup is available in three models: 64GB, 128GB and 256GB. Transfer speed is 560MB / sec for sequential reading, 420MB / sec for writing, 56,000IOPS for random reading, and 75,000IOPS for writing.

So yeah, it is not fast by any M.2 standards, and basically they are using a single bit per cell on BiCS4 Toshiba 3D TLC NAND. that thus operates in SLC mode. But here's the cherry on top of the cake: ... the write endurance is 3,600TB for 64GB, 7,200TB for 128GB, and 14,400TB for 256GB. Prices have not been announced.

So then, enterprise and professional market.
For mere average users, not so appealing.

100,000 rewrites. It will be obsolete with faster, better, cheaper tech way before its durability matters.

Don't underestimate high usage applications. The speed and specially the price won't be appealing to common users, but for enterprise they'll sure fit right in.
Plus, I think its smart to make SSDs with some kind of SLC cache, as we go into QLC and beyond, it would be ideal to have a 128Gb SLC chip to cache the most used files on a 1Tb or over QLC drive. Would make it's life allot longer and mitigate degredation. We need this tech, hybrid designs might be the future!

A very active R/W database (like a forum with thousands or tens of thousands of users) reads and writes constantly to the storage, 24/7 if it's a global forum.

All kind of business software might also change data continuously (for example, price trackers which constantly scan prices of hundreds or thousands of shops and adjust information and prices all the time) write like mad to the DB...

Some software that is related to circulation of items (logistics) constantly updates the state of every item... and there may be millions of items tracked.

Obviously this is an Enterprise drive, nobody said anything else.

But for that purpose it's great !
