I don’t think this product is worth it @ Rs. 8K even if it has DRAM.
Reason being?
Price went up
Woahhh!! Got one. With 4.4K TBW and SLC DRAM, this is a set and forget kind of drive. TYSM!

lol, now the price doubled
This is just Gen 3 with 3k speed, for 2k more, you can get 7k speed Gen 4, but no DRAM

I think you’re talking about SN7100 and you’re mostly right. But the one OP linked is better suited for caching and consistency, like high availability servers. And those drives are a steal at this price.
The drive is good indeed, but the endurance numbers might be exaggerated a bit. With the SM2262 controller similar to Adata SX8200, the endurance is rated double of what it should be. I have seen Phison E12 and E16 drives on different PHY spec having similar high numbers, but all the brands using these both controllers list high numbers, and them being used in other enterprise drives made me buy a few of these a couple of years back. Amazon has some good offers for other transcend drives if you want to keep an eye on them (like the 250H, which went for 8.5k before discount, currently OOS).

TIL
I’ll keep an eye out. Appreciate the suggestion.
Back in stock for those interested.
PS: I looked up their claims in detail. They seem to be using SLC NAND with parity check, which is superior to both TLC and QLC. So 4400 TBW doesn’t seem too far fetched. At the same time, there are few anecdotal mentions of this drive being dead within 1yr of 24x7 use. Not sure what to believe…
@thanatos, since you’re using these/similar, can you share drive health data? Like TBW, power on hours, health etc?
The thing is, LDPC and SLC caching (Not NAND) is typically used in most drives. Brands either publish the TBW rating in terms of what’s typical for the NAND used and keeping the warranty period with use case in mind, or just give a theoretical TBW based on the P/E cycle (Usually 3000 for current TLC NAND), and Transcend is doing the latter, I believe. No one’s using SLC in the consumer space, the few option are either used in Enterprise (Solidgm/Intel D7-P5810, which also is not SLC and rather QLC working in SLC mode) or Industrial areas. Above SLC, I have seen 3D Xpoint and its implementation in Optane drive, which are now discontinued… You can find Optane 900p drives around $300-400 for 800 GB (10 DWPD and higher-end ones go to 100 DWPD)

It’s 3D TLC according to this review linked on the Transcend product page :

Generally when they advertise 3D NAND, it usually means TLC/QLC.

It uses TLC i think

Thanks for such a detailed explanation. I looked at this document where it says SCL cache and confused it with the type of NAND.
As I understand, most modern M2 NVME drives use SLC caching, including a SN7100 which is much faster, but no DRAM. Both are TLC too.
Now I plan to use them for SSD caching in a NAS, where ~1TB is written per day. Would y’all say a SN7100 is better even with less than half the endurance? The NAS is on 2.5G network if that matters.
Is it good to use for PCIe Gen3 drive replacement for higher storage in a laptop?. Do the read/write speeds(MB/s) of 3500/2900 are enough for 4k video editing using this drive?
Looks solid for the price tbf
Is this better than T-force Carder Z44L ?
TBW rating is just a number decided by sales department for considering warranty. There are ssd models in market advertising 2000/3000TBW rating for same/similar flash used by other ssd models with 600TBW rating. TBW rating in itself is not a 100% guarantee that ssd will not fail before that or will definitely fail after crossing the TBW rating. SN7100 & similar ssd don’t have dram but they use a small portion of system ram as pseudo-DRAM just like how TLC/QLC is used as pseudo-SLC cache. I think it all comes down to your luck because both SN7100 & this ssd use TLC & there shouldn’t be that much difference between their real world endurance.
It is more than enough. In fact having more ram (preferably 32GB & above) is more important for 4k video editing along with a good processor/graphics card used by the video editing software.
Edit:
Found this reddit thread which seem to suggest this 220S model has some issues.
