It's not the "fastest SSD" on all metrics. My laptop's NVMe SSD, a Samsung PM981, benchmarks at 2100 MB/s sequential reads, whereas the Optane 905P measures only 1669 MB/s in Tom's Hardware bench.
- bitL 8y agoYou won't notice much difference between a regular SATA SSD and M.2 PCIe in normal things, like opening apps, playing games, booting etc. Only if you do 4K RAW video processing, copying files all the time and similar. This new SSD should give you the first noticeable boost in normal apps comparing to the rest of SSDs. Pity Intel couldn't deliver its original promises of 100x lower latency, that would have been even more impressive.
- pvg 8y agoDifference is noticeable, especially in boot.
- bitL 8y agoYes, but you won't feel like you just switched from HDD to SSD. Going from 15s to 12s is nice but won't make you super excited. This new Optane is the first SSD that might give you that feeling.
- pvg 8y agoI think you're underestimating the improvement you get from dropping SATA and overestimating how much room for improvement is left for typical users - when the i/o times get to the level of being perceptually unimportant, changes to them don't matter as much and developers are less incentivized to make things as i/o efficient. HDD to SSD type of change is hard to repeat.
- frankharv 8y agoI would imagine that HN audience does more than consumer tasks. Here is a real world figure. I can compile my FreeBSD NanoBSD build in 30 minutes compared to 2.5 hours on SATA3 SSD's Using a Toshiba NVMe XG3 mounted on a paddle card. I see zero heat issues with the Toshiba.
- textmode 8y agoAssuming enough RAM to hold the source tree, how does build time with root on mfs/tmpfs compare to the NVMe?
- hedora 8y agoThe 1000x latency wins are time to first byte from the media, not including transfer times. The NVDIMM stuff intel is working on helps alot with latencies, but, as others have noticed in this thread, NAND bandwidth is comparable to crosspoint in practice. So, if you are transferring many KB at a time, you don’t see the 1000-100x in practice. This breaks the performance assumptions made by all existing storage systems, so nothing but research prototypes are seeing anything close to 100x. Most of these points are moot for NVMe drives, because PCIe latencies are so high. The reviewed model, gets about 10x better latencies, for 4x the price, and that’s still significant.
- pkaye 8y agoOptanes reach their performance at much lower queue depth.
