Western Digital WD Gold 18TB SATA HDD Starts Selling

Western Digital started selling an 18 TB variant of its WD Gold line of "enterprise class" SATA hard drives (model: WD181KRYZ). The WD Gold series tops the company's SATA HDD lineup and its in the gray area between client and scalar enterprise segments, where the company sells its HGST Ultrastar HDDs. WD Gold drives are still rated for 24x7 operation, and can be safely used in large RAID arrays. The drives are confirmed to lack SMR and DM-SMR; and are confirmed to use CMR (conventional magnetic recording), which ensures predictable write speeds and random-write performance. The WD Gold WD181KRYZ features 7,200 RPM spindle speed, HelioSeal technology (the main disk chamber is sealed and filled with inert helium gas), and 2.5 million-hour MTBF. Performance numbers and cache size for the 18 TB model are unknown, but the 14 TB variant in this series offers up to 267 MB/s sequential transfers, and features a 512 MB DRAM write cache. The WD181KRYZ is listed on UK store SCAN for £520.

I wouldn't mind getting my hands on something like this - lots of storage space....Yet, here I am still trying to successfully get a 8TB HDD shipped from some place that doesn't pack hard drives like crap.

2 from Amazon - both tossed in plastic envelopes.

2 from Newegg - came in boxes, but lacked any packing material and the HDDs bounced around like rubber bouncy balls. I don't get it. I ordered OEM HDDs from newegg in the past and they came in packed in such a manner you could probably ship an actual egg in those boxes and it wouldn't break.

By the time I can acquire a decent sized storage device that don't cost an arm and a leg HDDs will be obsolete....

CMR in 18TB? Wow how many platters would this have? I have bad taste with SMR after a failing seagate 8TB drive, CMR still wins reliability wise if something goes wrong.

All of WD Gold drives are excellent performers. I've got a bunch of 12TB WD Gold drives and they easily get 240 MB/s. They are also extremely expensive but yeah, 5 year warranty, good performance, and enterprise grade reliability don't come cheap.

Flash capacity have exceeded hdd now. Only problem is just price now. Flash would replace 2.5 inch drives in a year or 2 now. The limits of 2.5 inch hdd technology have been reached. A 9mm hdd is still at 2TB for 4 years now. It would be replace like how the 1.8 inch hdd use in ipods and small netbook is replaced and also remember the micro drive? The 1 inch microdrive hdd use in dslr and ipod photo? It max out until 8GB until flash for much cheaper and alot more durable around 2006 to 2008.

There is a site called span.com I believe that deals in server grade kit :)



But there's also a Scan.co.uk which I end up buying from most of the time over in the UK :)

£28.8/tb (36 USD) isn't bad for a 18TB drive, let alone one with CMR, 7200RPM spindle, and 2.5 million MTBF. These are actually very appealing to me. Might pick up tsome for my unraid server.

It's £624 on span, £520 is without the VAT, so not quite as good a deal. In any case as 4K becomes the norm these drives are going to be essential without having to build your own NAS, but the pricing does also need to be right. SSDs are still horrifically priced in comparison mind.

The best way I've found to deal with is by buying retail at brick and mortar stores, in retail boxes. Unfortunately since there are few brick and mortar retailers that sell hard drives left anymore, this can be very difficult. Hard drives won't be as "obsolete" as soon as most here seem to think.

Only need 57 of these to make up a 1PB petabyte (1024 TB) of storage
