Thinking of replacing my Drive with a SSD. Probably happen about the time Leap 42.2 comes out.
Any words of wisdom here? I'm thinking I'll do the same drill I normally do, Fresh install, then copy /home a and /data over into similar partition sizes that I have before.
What to look out for? Any problem with a couple xfs/Luks partitions on the SSD? Brands?
Technologies? is a better question. For a lightly loaded PC, most any AHCI SSD will do great. I've mostly been buying Samsung SSDs with a SATA interface. For a state of the art experience that can handle a multi-threaded load like a server can throw at it, you want a NVMe SSD. Those don't have SATA ports, they are made to run at native PCIe speeds. Meaning fast as hell. Here's a year old article about one that was just released back then: http://arstechnica.com/gadgets/2015/10/950-pro-review-samsungs-first-pcie-m-... I have a Asus X.99 Deluxe MB that has a NVMe SSD connector directly on the MB. The SSD plugs into that vertically. (Unlike the picture in the article where the SSD is laying flat.) I have a Samsung PM951 (MZ-VLV1280) 128GB (I bought it to test functionality with, so the cheapest I could find.) I've been running Leap 42.2 (beta => RC1) on that pair since I bought the SSD (in June I think). I have had zero issues with doing so, but I mostly tinker with that machine, so I don't have any meaningful benchmarks. One new thing to learn is the drive is NOT /dev/sda It is /dev/nvme* nvme => Non-Volatile Memory Express nvme0 => The first NVMe SSD nvme0n1 => the first namespace of the first NVMe SSD nvme0n1p1 => The first partition on the first namespace of the NVMe SSD If your MB (like most) doesn't have a connector, you can buy a PCIe adapter for $25 or so dollars. Here's one example: https://www.amazon.com/Ableconn-PEXM2-SSD-NGFF-Express-Adapter/dp/B017JGVTAM/ref=sr_1_2?ie=UTF8&qid=1478131341&sr=8-2&keywords=nvme+pcie+adapter I haven't used an adapter, so no pros/cons from me. I assume they work with older MBs and CPUs. Alright, a quick performance test with my hardware. I was doing some 32-bit openSUSE 13.1 compatibility testing, so I openSUSE 13.1 boot CD booted at the moment. I did: time dd if=/dev/nvme0n1 of=/dev/zero bs=1M count=10000 It took 15.5 seconds to read 10GB., or 675 MB/sec. Again, that's with a 3-year old 32-bit kernel. Booting back to 64-bit Leap 42.2 RC1 9.8 seconds, or 1.1 GB/sec I'm actually surprised the 64-bit speed is that low.
