Cherryville - SSD 520

[Hopalong X]

Getting all the bugs out of the SF controller obviously didn’t come cheap (sorry could't help it )

$10M fly swatter.

[bluestang]

I still don't think it is SF.

[Smartidiot89]

SF-2281 done right incoming...

[johnw]

SF-2281 done right incoming...

How about a photo of the PCB showing the SF-2281 chip? That would be solid evidence.

*whistles innocently*

[Anvil]

I can't hear you

[Ao1]

Are they ever going to release this drive?

[johnw]

Are they ever going to release this drive?

At this rate, it seems that by the time it comes out, it will already be time for 20nm Kingcrest to replace it.

[lutjens]

It'll be released at the same time Intel gets around to pulling SB-E out of their butts...which is nearly when Ivy is due. Pretty sad when Intel launches their high margin processors and high performance processors last, and their run of the mill stuff a year prior...(1155 SB vs 2011 SB-E). Intel's strategy as of late feels like a disincentive to wait for the high performance parts...by the time they eventually materialize, the next generation of mainstream parts is right there with them in performance...

Well.. it's already available in my country (New Zealand), and on sale since Monday.. see: http://www.computerlounge.co.nz/comp...p?partid=16216 (p.s. our SSD prices are very expensive so no point comparing directly). I'm waiting for information on the controller/benchmarks before I consider buying it though!

[DooRules]

got 2 on the way, woohoo

[johnw]

It is strange if they are on sale already. The 520 is not listed on Intel's web page, and I cannot find any press releases or product announcements about the 520.

Notice that it says "34NM SSD" in the product title. The 520 is supposed to have 25nm flash.

[Anvil]

They are not available yet.
I could have ordered a week ago but prices are insane and the stores that lists the drives show availability in February. (the dates have varied a lot)

The drives might already be in stock though, just not listed as available, Intel have been able to do so lately.
(There sure are repercussions on stores that don't follow their rules/release dates)

I noticed that one of the stores listed Endurance : Data retention 5 year(s) as part of the spec.

I'm sure it won't be long, could be that there still are some issues though.

[lm358]

Notice that it says "34NM SSD" in the product title. The 520 is supposed to have 25nm flash.

I'm sure its merely a typographical error. Probably because the 510 series used 34nm. This is one of the "best" geek-type computer stores in the country, it's definitely available to purchase. Other NZ stores also list it: http://www.ascent.co.nz/productspeci...ItemID=8329326 those guys write 25nm I can only assume the distributor in NZ must have shipped stock early/before they were supposed to *shrug*

"In stock as at 20 Jan"

[Ao1]

I've noticed that Intel always seem to release info on a Friday (at least when it has anything to do with SSD's).

[DooRules]

Showed up a day early...

[c22]

I'm getting my hands on 520 this week!

[Ao1]

Showed up a day early...

How about some benches?

(A read bench with HD Tune woould be great if you have any data on the drive).

[johnw]

I'd like to see the SMART attributes as listed by Intel Toolbox (click on [SMART details]) rather than CDI. I'm sure CDI does not have the 520 in its database yet, so it is just guessing that the attributes are the same as, say, the 510.

Particularly, I am wondering if there is a "Flash writes" attribute, so that when divided by "Host writes" you can get the average compression ratio (assuming there is compression with the 520).

[DooRules]

clean array right now, 128k stripe, tried aida, cdminfo, intel toolbox, ssdlife, can find no reference to controller









The anvil bench score is about 1500 higher than I ever got with two M4's, atto is atto, as ssd not showing so well. I am on the enterprise drivers and they are not playing nice with the Intel toolbox yet. They are showing as 520's no problem, but when in an array they show no other data in the toolbox. When I tried the 11 series driver the Intel toolbox had full functionality.


Gone for supper.

Hmmm, I am disappointed. Nothing in the SMART attributes (except perhaps F9) that might tell us about the compression. But it clearly does have compression, judging by the 1022MB/s ATTO write vs. the 338 MB/s AS-SSD write.

Also, 338 MB/s sequential write (incompressible) is EXTREMELY disappointing for two 128GB SSDs in RAID-0. My single 256GB Corsair Performance Pro easily beats that at 415 MB/s. Heck, even a 128GB Performance Pro is specified for 340 MB/s sequential write.

For comparison, here is a 120GB Intel 510 AS-SSD:
