860 EVO, raid1

[ep0x73]

Grabbed a pair for $99 each @ NE to update two V-raptors I've had for 5 years with 45K hours on them [but still rock solid] but out of warranty.
simply swapped out, rebuilt, repeat, easy.

Blistering reads plus redundancy.
Only bad part, magician can't see the array so I can't bench but I did verify both drives were genuine before I rebuilt.
Also can't update firmware if they ever have one without removing, sliding it into my external USB, format and then install and update for both.

compare that to the VR raid1

This is with the disks 50% full, moving some stuff off I probably could hit over 1k.

Not bad for $198 bucks

Still not chipper they are making this model in China vs Korea like my 850 EVO was.

i find it painful using HDDs, SSDs all the way (for booting any way at least 250GB as well smaller drives are only £10-20 cheaper not worth it for half the space)

$99 each for 500GB 860 evos not bad really (norm i disagree with RAID 0 + SSDs but your using RAID 1 so ok as long as you're aware RAID 1 and higher is not a backup)

 

[ep0x73]

Yeah but using raid1 for oh, 10+ years without issue so I works.
Surprised by the read speeds, with spinners it helps but wow with SSD it's nice.

Put into perspective, paid around $160 for the raptors 5 years ago, now the same size SSD is $99? I'd say win.

no problem with using RAID 1 or higher with SSDs (unless Speed is your goal then your just better off with one large SSD as even SATA SSDs are many times faster than a HDD), TRIM can be the only issue if the raid driver is not passing along TRIM commands to the SSDs, if not you be relying on Garbage Collection only , still even in a degraded state SSDs are many times faster than a HDD

not saying raid does not work just it can fail in some cases (bad ram, PSU go pop and take out all your disks) always best to have some sort of off PC backup (nas, external hdd that you can unplug, cloud)

 

[ep0x73]

All indication even in RST raid 1 trim is passing as both drives show they are enabled.
Only minor issue is with 7 unlike 10 you can't force the OS to trim/defrag which I do on my 850 single on my 10 machine

 

[Wade88]

Why do you not just let it TRIM itself?

 

[ep0x73]

I am, trim is enabled. With 10 though you can force it by optimizing.

 

[likeman]

It's unneeded as it's done when ever free space is marked as free and Windows does it automatically on its own any way (part of maintenance schedule)
