InnoDisk Unveils the 3TS5-P Enterprise SSD with 2 DWPD Endurance

Engineers at Innodisk, using the latest 3D NAND vertical architecture technology, have delivered stellar performance and blistering speeds in the latest iteration of the company's new 3D NAND TLC SSD range. The Innodisk 3TS5-P SSD series complies with JESD219 standards complementing endurance workloads at enterprise level in situations where data compression or reduction is carried out for encryption purposes but doesn't distort the normal internal workings of the SSD.

The new 3D NAND TLC SSD series handles increased data storage demands in varied form-factors while maintaining read/write speeds for endurance and is designed for heavy workload applications. As data becomes the core of the IoT era and faster data speeds are required to necessitate reliability, the Innodisk 3D NAND TLC offers 2 drive writes per day (DWPD=2). This offers the potential of higher capacity within a smaller physical space thus lowering the mechanical interference and improving the airflow inside the system chassis, while also improving electrical use to reduce power consumption, boosting power consumption, and providing higher data write performance, as well as built-in hardware-based AES for data security.
Capable of being placed within the 2.5" SSD and M.2 form factors, it delivers data throughput with better latency of I/O operations and less total energy consumption. This provides improved power for day-to-day usage and works well with sequential writes. Average read and write latencies are reduced on a steadier 1 TB drive thus when combined with heavy application use, the Innodisk brings high and stable performance for application launch and file load times.

Dynamic thermal throttling maintains drives at safe data rates which not only improve SSD stability, but also keeps the system's service on track. The new series is best suited for heavy industrial workloads that require greater read latency, lower power consumption, enough MTBF time to serve overall duty cycles. This brings years of research and development into focus and strengthens our ability to carry the latest 3D NAND SSD flash memory to the forefront.

the Innodisk 3D NAND TLC offers 2 drive writes per day (DWPD=2).
Don't know if many people understand that statement. This is an impressive durability claim given TLC as the base. Yes it's 3D-TLC, but it's still TLC. With a MTBF rating of >3million hours the estimated PEC is(if I'm doing my math correctly) between 9,500 to 11,000. Unless I've missed something in the past few years, that is very good for TLC. I wonder if this is accurate and if it'll reach the consumer sectors..

DWPD is a relative spec, the second needed variable is warranty length.
DWPD = TBW / (disk size (in TB) * warranty (in days))

Naturally, press release, home page and spec sheet say nothing about warranty.
Assuming 1TB drive, 5 years would be impressive (~3600 TBW), 3 years is likely (~2200 TBW) and 1 year would be kind of expected (~730 TBW).
For reference, Samsung specs its consumer 1TB TLC drives at 600 TBW and basic enterprise TLC drives at 1 DWPD (5 years) - 1800TBW.

Flash P/E cycle limit is useless as spec. This is a nice round generic number for NAND Flash. 10 000 is usually the spec for better MLC and best case scenario for TLC. TLC is usually specced to 3 000-5 000 cycles.

Even if we wan to take that seriously, I doubt InnoDisk is willing to officially state 10 000 TBW for a 1TB TLC drive.

Yeah, but I actually read their data spec. The article even included the link to the official data sheet. Inno is claiming 10,000 cycles. Granted, after TRIM commands and wear leveling, it's probably much less "real" cycles than shown.

Considering InnoDisk makes highly specialised products, I don't doubt their claims. They have a fire protected SSD that can withstand 800 degrees Celsius. They make military and vehicle grade SSDs and DRAM, so they can't make up the numbers.

Even if you account for a 10% margin of error that's still decent durability for TLC of any type.

Agreed.

I still seriously doubt the 10 000 P/E cycles in spec. This is high for MLC and very high for (even 3D) TLC. These drives are using Micron 64-layer TLC.
Spec puts 1TB drive at 2222 TBW. Lets say there is a good 30% of overhead - this puts the realistic P/E cycles figure at around 3000 which fits the expectation.
3000 falls at the lower end of the TLC 3000-5000 spectrum which is expected for an enterprise drive that is likely to actually get most of its specced writes ASAP.
