Intel Optane 800p 60GB & 120GB
For some time now there have been very small Optane drives of 16 and 32 GB, which are meant to be used for SSD-caching. Until recently, you could purchase these under the name 8000p, but recently a new series came out in the form of the Optane M10. In any case, with capacities of 60 and 120GB, the 800p series is for those who want more than that, but still pay some attention to costs.
Compared to the small caching drives, the 800p drives are a lot more formidable. Because they consist of more dies, it is possible to write more extensively in parallel, which benefits the write speeds. Intel specifies a maximum of 640 MB/s, where the caching modules do not exceed several hundreds of megabytes per second. In addition, Intel has customized its firmware to support low idle-powerstates, which means that the idle power consumption of the 800p series is much lower.
Intel uses a more simplistic controller for the 800p (Intel SLM4B) than for its high-end models (Intel SLL3D), if only for the simple reason that the 900p controller is physically too big for an m.2 module. Although the five-year warranty is the same, intel does state a lot lower TBW-value of 365 TB.
On average the Intel Optane 800p 60GB and 120GB cost 146 dollars and 265 dollars respectively, which is between 222 cents and 246 cents per gigabyte. Of course this is still very expesnive, but it is a lot less than the price of the previously tested Optane DC 4800X which is more than 351 cents per gigabyte.
