11 июн. 2017 г. · Writing to a RAID 1 drive will never be faster than writing to a single drive as all data needs to be written to both drives.

4 дек. 2019 г. · Yes, but RAID 1 (mirroring) takes 2 disks. With 8 disks you will have 8X increase in read speed but 50% capacity when using RAID 10.

13 мая 2012 г. · I have heard that RAID 1 provides peace of mind (because of mirroring) but gives slower write (not read) performance.

3 февр. 2012 г. · That means reading one 10GB file won't be any faster on RAID1 than on a single disk, but reading two distinct 10GB files*will be faster.

11 мар. 2020 г. · Here is one explanation of the benefits of RAID 1: "As different disks can seek on different data, it [RAID 1] has up to 2x the random read IOPS ...

29 окт. 2019 г. · RAID1 in general has "same" performance on writing because you always write same data to both disks, but it can have "twice" performance for ...

13 февр. 2013 г. · RAID1 (mirror) is faster on reading and safer, but you loose half the space for a spare copy.

2 янв. 2011 г. · Raid1 can potentially improve READ speeds as each disk is read from in turn in much the same way as a striped array, remember, at this point ...

8 авг. 2019 г. · Depends on the raid chip hardware and driver if it will support reading from both drives or not. – Moab. Commented Aug ...

2 июн. 2010 г. · In short, use Raid 1 for redundancy, and for read speed if you uses advanced controllers. Raid 1/0 & Raid 0/1. This is a combination thing.
