Any reason to pick SATA over SAS?That SATA isn't so bad actually.
I just grabbed 4 of these INTEL DC P4511 2TB (no more left, sorry
Just to say that it might be worth watching this Seller, some of their Offer are quite good (although I could NOT negotiate THAT much on this one, I tried and got autorejected for 40-45-50-55 then finally on the last one I got accepted at 60 USD).

a SAS drive will not work with a SATA controller is the point.
if you have a SATA drive then it will work on almost any computer made the last 15 or more years.
News flash but SAS drive's also work in almost any enterprise computer made in the last 2 decades, this is after all a "Enterprise SSD deals" thread
100 on the original listing and 165 on the second one
EXPIRED - Ebay Dell 3.84TB SAS SSD $100 | ServeTheHome Forums
But that's a great deal, and as you can tell from the timeline of the thread, it was gone in minutes. The vast majority of buyers wait to make a decision to buy, and once they do, take the first price on ebay. But opportunistic buyers like most followers of this thread, who are happy to wait for months to grab a great deal (i.e. have the patience, the funds and available slots) are atypical. And I am actually out of that population (no more available slots). In fact I have a pile of unused 3.84TB SATA SSDs waiting in a closet which breaks my heart! I have been a net seller on ebay YTD.
According to https://datacentersupport.lenovo.com/bm/de/downloads/ds557652 the Drive in the Listing seems to be at least 2 Firmware Revisions behind (3202T2GB) compared to the latest (3205T2GE and 3205T2GC).Granted these are U2 at 80% health, but if you're looking for that would these be an ok deal?

Can we run the Linux Update Tool even though we don't own a Lenovo System ? Is it sufficient that the SSD itself is Lenovo ?
EDIT 1: I gave it a Try ... I could download
lnvgy_fw_drives_all-1.39.11-0_linux_x86-64.bin and lnvgy_fw_drives_all-1.50.16-0_linux_x86-64.bin.They don't really run as is (nobody checks if the File is running as User, just complain that they cannot write to
/var/log/Lenovo_Support/ux.log).Using
binwalk one can somewhat extract the File, but then we are left with a .std File that doesn't really give out its Type via file Command.Seems to just be Binary File, that's all, approx 1.3MB:
Code:
ls -lh ./_lnvgy_fw_drives_all-1.39.11-0_linux_x86-64.bin.extracted/image/files/3205t2ge.std

I was tempted by their previous listing, but from a that fresh seller it feels a bit risky.
(Reusing the same pictures with same serials when first listing already sold just adds to that sense of risk for me)
It did peak my interest for ruler format prices in general tho.
A fair bit of 600-750$ 15.36tb listings that has been sitting for a long time that would probably accept some okay offers.
Mixed Workload / Mixed Use Drive
.0.5 Drive Writes Per Day (DWPD) for a period of five years -> 0.5 x 3.84 TB x 365 x 5 = 3504 TBW, quite Good I'd say
Datasheet:
No mention about PLP or Power Loss Protection though, I wonder if it has another Name or if it's not there at all ?
EDIT 1: Never Mind, it just has their Proprietary Name described in the DataGuard Technology Section:
for amateurs of antiques: Dell 0Y12DP 6.4TB PCI-Express 2.0 x8 $150 Dell 0Y12DP 6.4TB PCI-Express 2.0 x8 Read Intensive MLC Application Accelerator | eBay
wow, I thought it was like the Dead Sea Scrolls of flash but it's only(?) from 2016:
fusion-iomemory-sx350-pcie-application-accelerators-datasheet.pdf
That is a Fusion IO SX350 card. It'll do >3GBps easy. Granted not as fast as the latest NVME etc, but 6.4TB for $150 or less? I'm almost tempted to buy them.Well Cheap, Good, Fast, pick 1 or 2 at most.
So Cheap it is, Good I don't know, Fast probably not
p.s. They work great even in the latest Proxmox.
Maybe the F40/F80 are closer to Dead Sea Scroll levels of antiquity? I think I have an F40 in a box somewhere. I was using it as a paperweight, but it got to be too old even for that.
I was tempted, but trying to do a little research before jumping.Well somebody bought them. Seller rejected my Offer of 90 USD / Piece
I set up the home NAS with SSDs to keep noise down (a handful of 1.92tb Samsung I got for $40 each when prices dipped). But, it was so popular with the family….its “full”. So have to get something else.
Little cooling fans on a PCIe card shouldn’t be too bad, right?
Microchips are not made to last Indefinitively (thinking mainly about the Controller). They mostly get killed by Over-Voltage Transients / Static Discharge / etc and of course they age much faster the higher in Temperature you go (Arrhenius Law). Which one "kills" first, whether it's the Calendar Aging or the Number of Write Cycles that each Cell experienced over its Lifetime (TBW), it's for sure a Combination of both.
Please Note that old SSDs have MLC Flash with "big" Cells Production Process (in Terms of Nanometers, ~ 20 - 30 nm) so that is better in terms of Longevity and Reliability compared to TLC/QLC NAND. Although in Terms of Calendar Aging, not sure if that makes a Difference. If it does I'd say that the MLC and "big" Production Process is actually better. Of course the same Remark applies to the Controller.
Capacitors mostly age over Time (Capacitance decreases over Time, Electrolyte dries up, ...) so that's for sure a Negative Thing. In these applications aging of Capacitors due to Load Cycling isn't a Factor. Since Manufacturers should design their PLC and Filtering according to the EOL Drive Characteristic (and hopefully they do so), then there should be some reserve Capacity to take that into account so even when old the Drive should perform correctly.
Price was good, but not "incredible" for when I bought them 2 years ago. Back then, $45-50 for single pieces seemed pretty common and I offered for 5.Those are some incredible Prices
If you have the Space for it and can give up the next PCIe Slot, sure. Or centrifugal Fan. Or Side Chassis fan depending on the Chassis Model.
Yeah, if I went the AIC route for expansion, I'd need to switch to ATX/mATX. Ports are maxed out on the current ITX based NAS, so no way to add capacity there unless I went fresh with larger SATA SSDs. I have a couple suitable chassis and boards I could repurpose from the homelab for a "new" NAS. So, I think keeping the current pool and adding additional storage is my best bet to save $$$. Just need to decide what to do
Well that's already a Premium compared to the 75 USD I was initially willing to spend
.Maybe I should have indeed gone with 3x, not sure, this way I can only do a Mirror. But at the same Time not being sure if I could update Firmware was a bit of a Risk Factor for me.
Now I'm having quite a different collection of U.2 SSDs though: 1.92TB, 3.2TB, 3.84TB and 4TB. Of course the 4TB (Intel P4500) can be "downgraded" to 3.84TB and the 3.2TB will be in another System so not really an Issue.
Those are the exact reasons, I'm redoing my SAN nodes. Needed more flash, but was out of slots. So...
10x pci-e 3.0 x8 slots...The chassis (Chenbro NR40700) will need a bit of surgery to fit this monster, but should give me enough I/O for years to come. The Chenbro already has ~1PB of spinning rust, but more flash is needed (who doesn't need more flash!).
god that would be so rad to run LLMs on. get a shitton of 3090s, 512GB of DDR3, a pair of 2697V2 or 2687W v2's and go crazyThose are the exact reasons, I'm redoing my SAN nodes. Needed more flash, but was out of slots. So...

No direct Experience on Capacitors and these Enterprise Drives but IMHO an Enterprise Drive with PLP where the Capacitor aged too much "simply" means that PLP is no longer effective (either not working at all i.e. Lost Function, or for too short period of Time i.e. Degraded Function), effectively it's the same Thing as having a Consumer Drive without PLP, and for most Scenarios with ZFS (even if PLP is highly recommended), then in the worst case you are only going to lose the last few Seconds after an unexpected Power Loss occurred. So the Issue will only manifest itself after an unexpected Power Loss, otherwise none at all. Some PLP Drives do indeed do a "self-Test" of the PLP Capacitor Function and report that Information in the SMART Attributes / Log.
Of course if the PLP Capacitor goes into Short-circuit that's a whole other Story, but that will likely not be reported at all, if anything a fuse Blows or your PSU trips. But how likely is that going to happen ...
Small Filtering Capacitors will not report anything to the Controller obviously, so the only Effect will be a slightly less filtering / decoupling of e.g. 3.3V Supply and some Signals.
True. Should have been more specific.
True. Hence the giant monster motherboard.
I'm already using two Adaptec 8 series in the chassis for the spinning rust, one per expander/24 drives.
Nah. That's fantasy stress testing stuff. Real life...a single pcie 3.0 x8 HBA is more than enough for 24x spinning rust, even the latest ones.
Yup. And that's replicated (well, not all, about half to 2/3) to the other SAN node. Both are identical.
True. Bought three of them years back. They couldn't give them away at the time. I think it was $200/ea shipped and came with a nice motherboard.
I don't need all 11 slots to have "openings". The Fusion IO SX350, the Adaptec HBA etc are all internal only. They just need to be secure enough in the chassis. It's only the NICs etc that need the slot openings.
It does. And they're open ended even! But...that motherboard is like $500...this was $27...less than a lunch.
No, sorry. It does have 11 slots except one of them is pcie-2.0 x4 from the PCH. I don't even look at these slots. blah...
The Chenbro NR400700 motherboard tray is essentially a full width (~17") 3U open chassis, since the power supplies sit "below" it, making the whole system 4U.
At one point, I had a stack of HGST SAS SSDs mounted next to the motherboard...
