If this product is unavailable in your region, you may need to use a specialist parcel forwarding service to take advantage of the deal. Both the Western Digital G-Drive 18TB and LaCie d2 Professional 18TB are perfect for storing massive quantities of data whilst offering very fast data access. They both feature 7200 RPM drives for fast data transfers. The LaCie includes a Thunderbolt 3 interface where the Western Digital only USB 3.0. You need to move up to the Western Digital G-Drive Pro 18TB to get the faster Thunderbolt 3 interface. They feature aluminium cases for improved heat distribution. Hard drives can get quite hot under continuous load, therefore having adequate ventilation will help extend the longevity of the drive.

By the spec sheet, the only difference between the Red Pro and Gold is the MTBF. In my machine side by side, I've found that to be very untrue. The Gold is quieter and noticeably faster. They're all on the same SATA III controller. Gold gets 50 MB/s faster transfer when past the write cash. That's 20% which is a pretty big difference for a drive that's claimed by the manufacturer to be "the same" spec. for write. The drive is made up of nine 2TB platters (with 18 heads) offering the highest areal density across the industry, 256MB cache and has a spindle speed of up to 7200RPM. There’s a dual-attached motor and RV sensors to guarantee steady performance, which means 1.2 million hours MTBF.

is certainly a massive amount of data. Whilst some will easily be able to consume it all, many will never be able to need such large data storage. Therefore I recommend you look at your specific needs before choosing a hard drive capacity. Simply choosing the largest capacity drive you can find may not make the most sense. Having multiple copies of data for additional redundancy, it may be safer to have 2 (or more) smaller drives with the same copy of data, therefore reducing the event of data loss if a drive were to fail. This is my first time on these particular drives, the Red PRO, it uses CMR technology which is supposed to be a step up from the old SMR technology, faster speeds and reliability, also these have a 5 year, (limited) warranty...the Pro is a little bit more expensive than the basic Red version, but hopefully the little bit more spent equates to a better drive overall with a longer lifespan...

You can also consider a drive that supports RAID (Redundant Array of Inexpensive Disks) that can offer data redundancy by writing data to multiple hard drives in parallel. This is referred to a RAID Level 1, and is supported on popular models such as the Western Digital G-RAID 2 or LaCie 2big RAID 16TB drives. Note that due to the drives being mirrored the available disk capacity will be half that of the total, so a 24TB drive will be 12TB, 16TB will be 8TB, etc.

Now you might be wondering why the advertised HDD storage does not match the usable data capacity. Most hard drive or SSD users have the same question- why actual drive capacity is lower than the space mentioned on the label? But before you blame the drive manufacturer for giving false information, it’s important to know the reason behind this capacity discrepancy. So, let’s find out how the capacity of hard disk drives is calculated and why their actual size differs from the advertised size. Lyve: Periferie-naar-cloudplatform voor massaopslag Lyve Cloud: Voordelige objectopslag, ontworpen voor de multicloudAvailable in capacities ranging from 2 to 22TB(1) with support for NAS systems with up to 24 bays | (1) 1GB = 1 billion bytes and 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment. Even though using only a 5400 RPM drive the USB 3 seemed fast enough for all but the most demanding tasks. While rebuilding the volume, each drive replacement on the DX517 took about 36 hours. It seems it will take about 15 hours on the DS918+ so I have to attribute that to a bandwidth limitation between 918+ and the expansion cabinet, not a limitation of the drive. 22TB in 15 hours is pretty OK considering all the space that has to be touched. I never had any good experience with WD devices. One them caused me to loose 15 years of photos and personal work. This NAS drive works perfectly for now (for the last month). But I'm not sure what will happen after a few more months. For the price i've bought it, i can recommend it. It's easy to assume that SSDs and hard drives are simple products when compared to laptops, TVs, or PCs, but there's still plenty to consider if you want to buy new storage.

The larger the drive, the higher the data transfer rate in general; Seagate quotes a 7.8% increase going from 12TB to 18TB, small but not-so-negligible. The numbers we recorded in our benchmark are unambiguous; this is a very, very fast hard disk drive when used as external storage. With the setup, I have a maximum of 9 slots for drives (4 on the DS918+ and 5 on the DX517). I have two 4-drive volumes with drive 5 on the DX517 being used as a hot spare. Best to allow a failed drive to immediately start the repair on the hot spare than get the money and wait for a drive to arrive while you sweat whether or not another drive will fail in that time. Supports up to 300TB/yr workload rate(2) | (2) Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations. To know why it happens, you need to know the difference between the Decimal system and the Binary system. Hard drive manufacturers advertise their products in the decimal system. But our operating systems, such as Windows or older MacOS, are based on binary math, which means storage is counted using base 2, not base 10, which storage is advertised as. This means that for the computer system, a KB is 1024 bytes, while for a hard disk manufacturer, one KB is 1000 bytes.Since your computers work on the binary system, there is an increment of 2 to the 10th power or 1,024 in each storage level. Therefore, in the computer system: Even though these are officially not on the approved hardware for the Synology DS918+ and DX517 expansion cabinet, they seem to work and seem to work well. One thing I noticed different than the 10TB WD100EFAX-68LHPN0 drives they replace. These are 7,200RPM where those are 5,400 RPM. Though that has not been a problem with my RAID-5 setup. Also, the pull about 2 less watts of power per drive and run about 10-degrees F lower in temperature.
