Nominally about 2700MB/s reading and 1800MB/s writing. It's a bit older, maybe it only reaches that speed using multiple I/O queues but our driver only uses a single I/O queue. >atabus4 at ahcisata0 channel 4 >wd1 at atabus4 drive 0 >wd1: <Samsung SSD 850 EVO 2TB> >wd1: drive supports 1-sector PIO transfers, LBA48 addressing >wd1: 1863 GB, 3876021 cyl, 16 head, 63 sec, 512 bytes/sect x 3907029168 >sectors >wd1: GPT GUID: 6a0b69cd-d01a-418e-8425-79570c1b52e6 >dk1 at wd1: "66562866-5ffa-43b0-88a1-d8a7c16e95ce", 3907029101 blocks at >34, type: ffs >wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133) >wd1(ahcisata0:4:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 6 >(Ultra/133) (using DMA) That drive should sustain 500MB/s reading and 450MB/s writing. It's a bit confusing that it is exactly the same capacity as the NVME card. >dk0 at ld0 (5d0d649e-9280-4a8c-9fe5-e28de7f0783b) deleted >ld0: GPT GUID: 39b3bde1-cbef-4410-bbb8-37f0ffdda723 >ld0: GPT GUID: 39b3bde1-cbef-4410-bbb8-37f0ffdda723 >dk0 at ld0: "2636dcf1-da9e-41b5-9803-78114f38b223", 3907029101 blocks at >34, type: ffs Probably just a rewrite of the GPT label. -- -- Michael van Elst Internet: mlel...@serpens.de "A potential Snark may lurk in every tree."
