Cheap ZIL SAS SSDs?

[MiniKnight]

Found these cheap potential ZIL drives here:
10 DWPD = http://www.ebay.com/itm/Samsung-SM1...0-6Gb-s-MZ6ER100HAFV-00003-SAS2-/391294332313 Samsung and 100GB SAS. $80 obo. Can use in dual ported mode for HA ZIL which makes it a bit better than the S3700.

Also because I'm too lazy to make another post 50GB SLC SATA II SSD from Seagate $40: http://www.ebay.com/itm/Seagate-Pul...LC-Solid-State-Drive-9VC151-001-/272016728998 It's the cheap.

I have some of the older Samsung 50gb SLC.

They're nothing like a S3700 -- performance-wise. Eedurnace, maybe, but the rest not so much.

Faster than spinners, but these are not much less power.

I use them in some mysql-write servers that just write consistently and don't have a need for high-perf. I just used them since I had them, andpower is a bit less than a spinnner.

Can you setup your SLOG POOL to be more than 1 drive to increase perf (pool of mirrors) or no?

The mirrored ZIL is a nice use case if you are doing active-active SAS ZFS. I have a few of the 200GB models and they have worked very well.

Patrick, could you elaborate?

Since I saw his flaying to Taipei post I will give it a shot ---- look at ixSystems and their active-active enclosures. You need SAS not plain SATA to have two systems access a drive. Literally you'd setup two identical systems and if one failed, the other can still access the drive.

I assume you meant 'flying to Taipei'? Otherwise, not sure where whippings enter this?

The Samsung SM1625 100GB SSD Drive looks interesting (the first post SAS SSD). (StorageReview launch summary from 2012)
4 Watt Idle Power Consumption and 9 Watt active.

It's not really helpful for people to post about SATA SSDs, given the thread title refers to SAS SSDs...
