Saw these last night before u bought the OCZs (see new thread here). These seem like relatively new, pretty solid drives - is the consensus that these are better than the HGST drives from a few weeks ago?

HGST > Cloudspeed > OCZ

But these cloudspeeds are very good drives that come from the smart acquisition or another one.

Are these drives any good? Maybe it's worth making a SSD only NAS at these prices.

They are ok for NAS type duty for sure, anything that is not writing too much is fine. (Note that they are still rates as 0.6 DWPD so that’s a lot of data it’s just a question of the IOP’s performance for writing is not fantastic)

I have a ‘NAS’ of Samsung PM863 drives for just files, works great, sure beats spinning disks which are simply used now only for backup.

Sub 1 DWPD on these larger drives is not too scary. 0.6DWPD on a 2TB drive for 5 years is probably 2PB+ of writes.

When drives were 100GB, 200GB, 400GB and similar capacities, high DWPD was more important. As we move to many TB drives, we are going to see 1 DWPD become more of a rarity. 1 DWPD on a 2TB drive is the same amount of data written as 20 DWPD on a 100GB drive.

Especially in the context of file servers or general use data, only in DB heavy write environments or cache usage is it likely an issue and those systems usually are 3-4 years life only as well.

Micron 1100 is the cheap consumer drive. They don't have power loss protection. After having Samsung 850's die in servers, I'm not putting more consumer crap in my servers.

I am itching to buy couple of these 1.9TB SSD.
I have a self impose rule to wait 24-48 hours from the time of deals was posted.

I have few Cloudspeed 800-960 gb ssd in various lab machines now.

Have too many SSD not being used at the moment.

I would buy this over the Micron 1100. These are enterprise drives and I no longer look at SATA SSDs as a performance tier.

How does one recognize an enterprise grade ssd? I know sas ones definitely are, but in the sata realm it still seems pretty jumbled to me.

Read reviews of the drive. Some sites like StorageReview.com - Storage Reviews haved tested a lot of enterprise drives. STH also has many articles mentioning them, but many of the older reviews are not deep tests that shows the real significance between enterprise and consumer drives.

An enterprise drive should always come with PLP(power loss protection), but newer drives like Optane is based on a new technology that don't need it. So the consumer Optane's will in many cases outperform enterprise SSD's.

A lot of the sata drives come from Samsung, intel, HGST, toshiba, and Sandisk.
Sm863, pm863 from Samsung are recent sata ssd.
Intel s3500 series
...

Enterprise sata is not that common I would say compared to SAS but they are out there.

Worst case ask here.

Also enterprise normally reserve more space for bad nand so think 240gb, 480gb, 960gb, 1.92tb, 3.84tb where consumer will be 256gb, 512gb etc...

Thank you very much for the replies. The size thing makes a lot of sense and should be a quick and dirty way for me to spot check. :)
