P51 Max Storage

Has anyone tried maxing-out a P51 with a pair of Samsung 960 Pro M.2-2280 2TB drives and run this in RAID to give 4TB?  If not, should any problems be expected?

 

Along with a SATA Samsung 4TB drive in the other bay, this would give a max of 8TB?  I currently run a W520 with 5TB of SSD (1TB mSATA, 2TB in regular bay and 2TB in CD drive bay).

 

Thanks.

Re: P51 Max Storage

The largest platter drive that will fit is 7mm, Samsung makes a 7mm, 4TB drive?

Re: P51 Max Storage

I don't know of a 2.5" 7mm platter-based drive bugger than 2TB.  Samsung makes a 4TB 2.5" SSD, but they are expensive, about $1500

Re: P51 Max Storage

I was considering the Samsung 4TB SSD for the additional drive - Like Richk says (inadvertantly?) the platter drives are a b*gger (heavy, noisy, etc).  But this was just to emphasise that it should be possible to run these machines with 8TB of storage - actually 8.5TB of you add a 512MB M.2-2240 as well.

 

No one has answered my main original question - which is to ask if there is a ceiling on the size of RAID array (like the 2TB drive limit of old) to allow the use of TWO 2TB M.2-2280 drives running in RAID to give a 4TB drive.

 

Thanks.

Re: P51 Max Storage

I don't know of anybody who has tried 2X2TB so I cannot guarantee, but the RAID chips and the drivers support much larger arrays than 4TB.  I cannot imagine that there would be a problem.

Re: P51 Max Storage

There is a M.2-2240 slot in the P series? Where?

Re: P51 Max Storage

I understood that the P51 WWAN slot could take take an M.2-2240 card?  Perhaps this is only true on the P51S? Could someone confirm or deny this?  There was a discussion of this in the thread:

 

P51S with 2 drives: 4TB SATA & 2TB m.2?

Re: P51 Max Storage

I am under the impression it went in the WWAN port, I was planning on using an Optane drive there, but i have not yet confirmed if this will work, The physical port is there on a P51 and P50, but from what i understand the port may not be connected to the controller. If anyone has any info on this it would be greatly appreciated.

Re: P51 Max Storage

Hello,

 

So far, Intel has only announced Optane cards shipping in M.2 2280 single-sided form-factor card that uses 2 PCIe lanes (not 4 lanes like a modern NVMe SSD).  I don't think they will fit in a M.2 2242 slot.  Also, keep in mind current Optane technology is used to provide a modest speed boost when paired with a conventional rotating media HDD, not a SSD.  They perform slightly better on synthetic benchmarks in read operations than SATA SSDs, but write operations occur at about half the speed of a quality SATA SSD.  As for NVMe SSDs, they are slower on both read and write operations, so adding one to a NVMe SSD-equipped system would slow it down.

 

At this point in time, the technology is kind of like a newer generation of the old ExpressCache technology.  I'm sure that will change in the future, but for now, the M.2 2280 version seems targeted at improving performance for HDD-equipped PCs.

 

Regards,
