Also changed NAND
https://www.reddit.com/r/sysadmin...?con
DRAM is optional and even drives that do have it can have different ratios. The ideal amount is 1GB DRAM per 1TB NAND. DRAM is primarily used to store a copy of the mapping table (FTL). This is used to keep track of where data is stored in the NAND. DRAM is much faster than NAND. DRAM-less drives have to constantly access the FTL directly from the NAND. Having DRAM can substantially boost performance and should help increase the longevity of the drive. DRAM is NOT a write cache!
Some NVMe drives have a feature called Host Memory Buffer (HMB) that uses system memory as a substitute for DRAM. This is less ideal than the drive itself having DRAM but far better than nothing. SATA SSDs can not support HMB.
The pSLC cache is the write buffer. Virtually all modern consumer drives have this, whether they advertise it or not. It runs a portion of the MLC/TLC/QLC in pseudo-SLC mode, allowing for very fast writes. Once the cache is filled, write speed can drop off a cliff, sometimes as low as single-digit MB/s. How much it drops varies a LOT, depending on the design of the drive. Cheap, DRAM-less, and/or QLC drives tend to take the biggest hit. Some higher end SATA drives may see little to no drop in speed.
The implementation of this cache also varies greatly. Some drives use a potentially small static pSLC cache, that will always hold the same amount. Many use a dynamic pSLC cache, which shrinks as the drive gets fuller. Even these can vary greatly in their size. Depending on the implementation, the pSLC cache can range from a few GBs to hundreds of GBs.
Having explained all that, the question becomes, which cache are you asking about? As far as DRAM is concerned, the Samsung 870 EVO has the ideal amount at 1TB+. The Crucial MX500 is still ideal at up to 500GB. Even though the larger models now only have 512MB, they'll still probably perform well. I'm not sure there are any other compelling choices in the SATA arena.
As far as the pSLC cache goes, it's a different story. Quality drives, like the 870 EVO and MX500, tend to only have moderately sized pSLC caches. Cheap, DRAM-less drives can be all over the place, anywhere from tiny to enormous. Even ones with a huge pSLC cache will quickly be overtaken by the quality drives, once the cache is exhausted.
That was sort of a long-winded way of recommending the Crucial MX500 or Samsung 870 EVO (if you can find the new revision). Also, don't put much stock in old reviews of drives. Many have changed hardware over time.

NVME are 3-5 cents per GB
So all SATA SSDs need to be at 1-3 cents per GB to sell otherwise good luck selling them.

It makes very little difference in part because you're often interfacing with the RAM rather than the flash directly. The max throughput also doesn't matter much when you're accessing many small files and your controller is only so fast at finding specific flash addresses and communicating with the I/O chip on the CPU.

I'd think a1TB SSD constantly writing multiple video streams would not last very long.
Samsung 870 Evo: The Samsung 870 Evo is a highly regarded SATA SSD that offers excellent performance and reliability. It comes in various capacities ranging from 250GB to 4TB and features a larger 4GB LPDDR4 cache. The larger cache size helps improve overall performance by storing frequently accessed data for faster retrieval.
Crucial MX500: The Crucial MX500 is another popular choice among SATA SSDs. It offers a good balance of performance, reliability, and affordability. The MX500 is available in capacities ranging from 250GB to 4TB and features a 1GB LPDDR4 cache, which helps enhance overall responsiveness and speed.
WD Blue 3D NAND: Western Digital's WD Blue 3D NAND SSD is known for its solid performance and durability. It comes in capacities ranging from 250GB to 4TB and features a 1GB cache. While the cache size is not as large as some other options, it still provides a boost in performance by temporarily storing frequently accessed data.
SanDisk Ultra 3D SSD: SanDisk, a subsidiary of Western Digital, offers the Ultra 3D SSD with capacities ranging from 250GB to 4TB. It features a 1GB cache that aids in improving overall performance and responsiveness.
Kingston A2000: While the Kingston A2000 is an NVMe SSD, I mention it here because it offers excellent performance at an affordable price point. It utilizes the PCIe NVMe interface, which provides faster speeds compared to traditional SATA SSDs. The A2000 comes in capacities from 250GB to 2TB and has a 2MB DRAM cache, further enhancing its performance.
Remember to check the specifications and reviews of the latest models available at the time of your purchase to ensure you get the most up-to-date information and select the best SSD that meets your specific needs.
Golf clap. You know how to post useless info using a readily available AI program which anyone can do as you can see here.
The Samsung 870 EVO has 1GB DRAM per 1TB NAND. Only the 4TB model has 4GB DRAM. I'd also take issue with the claim of excellent reliability. This model has been plagued with reliability issues.
No current variant of the Crucial MX500 has 1GB DRAM. Originally, the 1TB model did. Now, ALL models have 512MB DRAM. Also, it's DDR3L, not that it really matters.
The WD Blue 3D / SanDisk Ultra 3D have been replaced by the DRAM-less WD Blue SA510. There is no point to buying this drive, unless you like overpriced garbage.
I can't comment on the Kingston A2000, other than to say that it definitely doesn't have 2MB DRAM.
I hope you enjoyed some more useless info. I guess your AI program isn't quite ready from prime time.

which is 8TB for $115 - which comes to 1.4c/GB, which, rounded down to the nearest penny is 1c. Certainly at 1TB, you'll be closer to his "3c" or more.
