I bought and installed two 1TB 25 seagate barracuda with 128MB cache in my MacPro machine I noticed inmediately how slow these hdd are compared to the previous 35 hdd I know that these 25 are Since the 25" is quite smaller physically vs the 35" drives, the media needs to be more perfect for 25" drives vs 35" The yield of platters/media for larger capacity are fewer and thus will cost more The same reason applies to 70rpm vs slower drivesSeagate Savvio 10K4 STSS 600GB RPM SAS 6Gb/s 25" Internal Enterprise Hard Drive Bare Drive Average Seek Time 3ms Average Write Time 454ms Average Latency 3ms Height (maximum) 95mm Model # STSS Return Policy View Return Policy $3449 –

It can accept either 25 or 35" drives Thecus' N0503 (Figure 2) accommodates 25 and 35" drives with an interesting approach—a plugin card The standards in the industry for both 35" and 25" hard drives are 5400 and 7,0 RPM We recommend sticking to 7,0 RPM as the hard Something also to bear in mind is that 25" PATA/IDE hard disks use a combined powerdata connector, unlike 35" drives that have a 4pin molex power connector AND a 40pin data connector You will need an adaptor (such as the one included with the kit above) in order to connect a 25" disk inside a desktop computer
25 in are more portable and can easily fits inside your pocket, where as 35 are heavy and you will have to carry a power adapter, which makes the size as big as of a shoe box Neither of them are reliable, these both expansion cases have regular desktop/laptop drives inside them USB 30 connector on these case is also very fragile The difference will be that 35" you'll be interested in will be 70RPM while 70RPM is nonexistent in 25" I would not worry about writes with SSDs They are not expensive these days Intel If you value portability over price, then 25" If you value price over portability , then 35" I always say that speed is the LEAST important factor when selecting an

The 35" drives use side screws and the 25" drives use screws up through the bottom through 4 holes that align the drive with the SATA socket on the back plane Laying an empty ReadyNAS tray upside down over a 35" drive and then a 25" drive on top of that and aligning the SATA connectors, there are several points Conclusion Backing up to a 35″ hard drive uses half the power (assuming the drives don't go into standby mode) Obviously there are a lot of other scenarios we can imagine If both drives were in use 24 hours 25″ drives – 3 drives * (521W*24Hrs) = 3751 Watt*Hours per day 35″ drive1 – 1 drive * (8W*24) = 192 Watt*Hours per day The IronWolf family of NAS hard drives come in 1TB, 2TB, 3TB, 4TB, 6TB, 8TB, 10TB, 12TB, 14TB, and 16TB versions and with threeyear warranties Do note that only configurations of 4TB and above

A 25" server hard drive delivers somewhat slower transfer rates than 35" drives do, but they beat them in access time A 25" SAS drive currently reaches capacities of 147 GB at 10,000 RPM rotation speeds, or 73 GB if you want a 15,000RPM drive At the same time, 35" SAS and SCSI hard drives have been available in capacities of 300 GB for a 1 point it wont matter if the server has 25 or 35 only difference is price so if you NEED to have that small of a case, then yes you will be paying extra for convenience you can also run a headless, slightly bigger nas using a server boards IPMI function (that is what i am planning to do with my nas build) food for thought Permalink Karl0508 The new 25" WD Red comes in the 95mm zheight and two capacities;
35" drives are not always LARGER than 25" drivesa 12TB 25" SSD can store more than a 1 TB 35" HDDThe 25" may allow servers with a smaller foot print like 8x 25" hot plug HDD in a Dell 1U server Then you need to ask yourself if you can use SAS or SATA HDD for your 30TB array and how many slots does your hardware have ?I am using 25" drives 24/7 for years and had no failure so I think the difference is more down to space and energy consumption as you mentioned 2 level 2 8fingerlouie 2y And speed 35" drives usually spin faster, meaning faster access time, and faster reads Though if you use NAS drives which spin at 5400RPM, the difference is small 2Other than that there really isn't a big different between 25" and 35" 35" drives have the higher capacities, but a lot of enterprise use 25" because they are physically smaller so it keeps appliances physical smaller Hope this helps and feel free to ask any questions you may have ) 1

The biggest 25" drive on the market is 2TB, which costs roughly $90 A 35" drive of similar capacity would be about $70 So an array created with 25" drives instead of 35" drives would be about 30% more expensive However it would also fit in a significantly smaller enclosure, draw less power and be quieter Four platters can create 600GB, 15,000 RPM, 35" SAS hard drives, while a comparable 25" model runs on only two platters A 25" enterprise drive running at only 10,000 RPM is usually based on So instead of returning the hard drive, I am actually considering using the 25 inch in the desktop computer As a lot of servers now use 25 inch hard drives, one would presume that 25 inch hard drives are actually more reliable than 35 inch hard drives Also all the SSD Drives mostly seem to be 25 inch as well

A 35" drive will typically use 12v for the motor and 5v for the circuit board A 25" drive will typically use only 5v, for both motor and circuit board The hard drive label will tell you the maximum power consumption and from which voltages that power is taken This tells you the hard drive will consume a MAXIMUM of 5w x 06a 12v x 045aThe 25 HDDs are slower than their 35″ equivalents, but I found that especially Samsung and Western Digital have made some very good small form factor HDDs at 70rpm which are reaching easily 100–1MB/s transfer rates, and that is excellent I saw old HDDs from both forms factors, it also depends on the technolo Continue Reading Colin WrightI am using with synology 1817 NAS (16 Gb ram,10Gbe network card)My computer have i9 CPU and 25 Gbe ethernert Lan,Cruical NVMe P2 SSD They are connecting directly (cat7)with one another Firstly synology hdd is not compatible my synology nas server ds 1817Synology customer service accepted this situation
With the capacity to store 5bits per cell and up to 32 (2^5) levels, PLC is expected to knock down HDD's last line of defense, namely high storage capacity at affordable pricesFor power concerns on average 3x 25" drives uses about as much as a single 3,5" For price concerns the memory space in 2,5" drives is significantly more expensive, by the margin you will never save on electric bill Not to mention the requirement and power of additional interfacing hardware 2 level 1 The role of 25" hard drives is changing The smaller form factor now provides increased storage density and improved power efficiency compared to
