toivos kirjutas: SurfData kirjutas: toivos kirjutas: SurfData kirjutas: Kiirused on päris nobedad: Ehk siis nobedaim traditsiooniline HDD Kuna 2,2TB pealt toimub järsk kiiruse hüpe, siis sealt edasi testid sa ketta algust. seda küll, et nüüdsest oleks vaja uuemaid TASUTA programme ketaste testimiseks tänu sellele 2,2TB piirile. Samas jääb ta endiselt kiireimaks 7200rpm kettaks jupiks ajaks. See ei muuda fakti. Ketta lõpus olevat kiirust teada ei saa nende progedega, aga algusegi järgi on juba üle 150MB/s mida teised ei suuda. Samuti 2,2TB peal on kiirus veel 100MB/s, mis on küllaltki hää peaks mainima Küsimus ei ole ainult kiiruses, vaid petlikus illusioonis, et kõik nagu oleks korras. Piisab aga ainult süsteemil püüda kirjutada sinna 2,2TB tagusele alale, siis tegelikult kettale kirjutatakse hoopis algusesse. Kasutaja on võib-olla pikka aega istunud viitsütikuga pommi otsas ja kui ükskord sõber talle näiteks hunniku filme kettale kopeerib, siis hävib data ketta alguses. oot mismõttes, pmst üle 2,2tb muutub kettas mõttetuks ?

NB Tähtis info kõikidele väliste usb boxide kasutajatele (eriti vanade boxide kasutajatele). Sinna sisse ärge pange 3TB kettaid, kus on andmeid rohkem kui 2,2TB peal....või kui tahate panna, siis testige ennem ära, kas USB box toetab. Nimelt minu ürgvana boxi sees nagu eelnevalt kirjutasin siis kui partitsioon oli peal, oli 3TB maht nähtaval. Nüüd sai testitud asja ka andmetega. Kui panna boxi 3TB ketas mis on andmeid täis, siis viimase 550gb (või 750gb) peal olevad andmed ei olnud kättesaadavad Kataloogide kohta osadele ütles inaccessible folder, osadesse lasi ligi. Kustutada samuti viimase osa peal olevaid asju ei saanud (ainult nähtaval olid).
Pärast sai ketas muidugi otse mobo külge pandud (s775 sata-II) ning win küsis kohe ketta skännimist ja fiximist enne kui kasutada. Sai see ära tehtud, probleeme ei olnud. Boxis inaccessible folderid olid kasutatavad ja ligipääsetavad. Mis seisus muidugi andmed olid ma öelda ei oska, kuna suvaline läbu oli ja kontrollida sellise asja töökorras olekut raske. Kustutada lasi seal siis juba ka neid asju.

Lihtsalt infoks siis, et olge ettevaatlikud ja testige enne oma boxi töökorda ja toimimist suurte ketastega

Ehk siis sinu enda 07.12 kirjutises olev "Ka ketta suurus kõik täies mahus kasutatav" ei vasta tõele.
Huvitav, kas mõni eraldiseisev 3TB toetav normaalse hinnaga USB box ka meil müügil on? st. ainult box, ilma kettata. Hetkel pistaks sinna 2TB sisse, hiljem suurema.

TechConnect Magazine

Spoiler

tsitaat:

Earlier this week it went big with some 3TB drives and now Hitachi GST is going small, or rather slim, by introducing the 500GB, 320GB and 250GB Travelstar Z5K500 series 7mm-thick 2.5-inch hard drives. These single-platter HDDs operate at 5400 RPM, have 8MB of cache memory, a SATA 3.0 Gbps interface, consume 1.8W when reading/writing, are Advanced Format-ready (have 4kB sectors), feature a sound output of 2.1 bels during seeks and, optionally, will be available with bulk data encryption. The Travelstar Z5K500 drives are set to start shipping this month, with the 500GB model already being announced as the base for G-Technology's new G-Drive slim portable hard drive expected to become available in early 2011.

tsitaat:

Hitachi Global Storage Technologies (Hitachi GST) on Thursday announced a series of new single-platter 2.5" hard disk drives (HDD) that are based on the sixth-generation perpendicular magnetic recording (PMR) platters. The latter feature higher areal density than currently available drives and can thus enable 3.5" hard drives with 4TB or even 5TB capacities. Hitachi Travelstar Z5K500 hard disk drive comes in 2.5" form-factor and is just 7mm thick. The most important thing about this drive is that it is based on one 500GB sixth-generation PMR platter with 636Gb/inch2 areal density. The platters themselves will eventually enable 2.5" drives with 1TB or 1.5TB capacities with two or three platters inside. Moreover, 3.5" platters with 636Gb/inch2 areal density will have capacity of around 1TB, which means that it will be possible to create 4TB hard drives with four platters or even 5TB HDDs with five platters in the next twelve month, which is in line with expectations by analysts. The Travelstar Z5K family of hard drives offers 500GB, 320GB, 250GB capacities, 5400rpm spindle speed, 8MB cache buffer, Serial ATA-300 interface. The manufacturer declares 5.5ms average latency, 13ms average read seek time, 1.8W maximum power consumption during seek and 0.55W minimum power consumption in idle mode. “As the industry’s only 500GB one disk product and the only second generation 7mm product family, Hitachi continues to push the bar higher, and is leading the shift from 9.5mm 2.5" drives to 7mm 2.5" drives across a broad range of market segments," said Brendan Collins, vice president of product marketing at Hitachi GST. According to IDC, 500GB, mobile 2.5" hard drives represent 22% of the market today, with this capacity growing 42% annually from 2010 to 2013. Offered in a complete family of 500GB, 320GB and 250GB, which satisfies more than 77% of today’s capacity needs in the portable PC market, these drives are the industry’s only second-generation family of 5400rpm 7mm z-height drives, which are designed as a direct replacement for standard 2.5", 9.5mm drives in everything from external drives to laptops, netbooks and blade servers. All this combined puts the new Hitachi Travelstar Z5K500 drive family in the industry sweet spot of opportunity in the mobile 2.5" market, according to the company. “Ultra thin and light devices are, without argument, a growing trend. In order for these innovative designs to live up to their true potential, they need rugged, reliable high-capacity hard drives that can withstand the rigors of a portable environment and satisfy the storage demands of their end users, and Hitachi continues to deliver,” added Mr. Collins. All Hitachi Z-series 7mm drives feature common connectors and mounting points for standard integration into existing systems. The Travelstar Z5K500 drive family will also be offered in enhanced availability (EA) models in capacities of 320GB and 500GB, which are designed and fine-tuned for applications needing “always-on” protection in 24x7, low transaction environments including blade servers, network routers, video surveillance and compact RAID systems. The Travelstar Z5K500 family will be shipping to select distributors in December.

Intel updates storage driver to enable 2.2+ TB HDD support
TechConnect Magazine

Spoiler

tsitaat:

Intel has recently released an updated version of its RST (Rapid Storage Technology) driver which brings support for hard drives with more than 2.2TB of space, like the 3TB models introduced by Seagate, Western Digital and Hitachi. The RST 10.1.0.1008 driver is available here and it works with multiple Intel-based motherboards, up to those powered by the 5 Series chipsets. Intel warns though, that support for 2.2+ TB drives isn't the same with booting to such storage solutions. For that you'll need an operating system and UEFI BIOS that supports booting to a GPT partition.

mnjahh, kurb tõdemus on. Omal ajal 80-100€ maksnud Promise TX4 sata-300 PCI 4 pordine kontroller ei söö 3TB kettaid Sai reede õhtul testitud. Näeb ainult 746gb Sai proovitud et mujal 3TB part peale ja siis kontrolleri otsa ning 3tb datat peale koppama....lõpuks error ees ja enam vastu ei võta midagi ja vanad andmed pole ka kättesaadavad Seega peab kurbusega tõdema, et suvaline juust sata-1 kontroller mis maksab ~20 EURi sööb 3TB kettaid ja kordi rohkem maksnud sata-II kontra seda ei tee Tootja kodukalt vaadates on bios sama mis kontral 38.94KB 1.00.0.34 Windows 4/8/2005

Seega tasub siiski vanade kontrolleritega ettevaatlik olla. Ma pean nüüd sellise kontra endal millegi asisema vastu välja vahetama

Western Digital "Evaluates" Feasibility of Hybrid Disk Drives.
X-bit labs

Spoiler

tsitaat:

Manufacturers of hard disk drives (HDDs) have traditionally been very conservative in various ways due to the fact that their products are mission critical for many customers. As a result, companies like Hitachi, Seagate or Western Digital are working hard to make their drives as reliable as possible. However, the approach of leading edge HDD companies towards solid-state drives (SSDs) seems to be over-conservative. Apart from Samsung Electronics and Toshiba Corp., which are the world's largest makers of flash memory, neither of leading-edge makers of hard disk drives - Hitachi, Seagate and Western Digital - still have not unveiled broad lineups of solid-state drives for consumers. By contrast, various suppliers of dynamic random access memory (DRAM) have already launched large families of SSDs. Apparently, Western Digital simply does not believe in SSDs for consumers, despite of the fact that many notebooks nowadays utilize solid-state drives instead of hard drives. "We have taken a look at and in fact shipped product into the SSD, in the client environment, and we do not find a compelling value proposition there either for manufacturer or for customer because the economics do not work. The cost of the storage/performance is too high," said John Coyne, chief executive officer of Western Digital, during the most recent conference call with financial analysts. Seagate Technologies has already introduced a so-called hybrid disk drive (HHD), which contains a rotating media as well as a large flash-based cache. The company believes that in five years up to 80% of its products will be HHDs. Western Digital is also evaluating feasibility of hybrid drives. "We also continue to evaluate the opportunity to combine rotating magnetic storage with flash into hybrid solutions. [...] [At present] we look at client environment and look at what might be an attractive offering that combine the best of both worlds in terms of the performance of solid state with the capacity of rotating media, [...] which [would] provide an accessible price point," said Mr. Coyne. Apparently, in order to ensure high performance of HHDs, support from operating system is needed to provide truly high performance. "We look out into the future where such a device would be supported by operating system capability, which it is not really supported well today. As we look at that over the next couple of years, we see an emerging opportunity for such a device family to offer performance capacity and value," concluded Mr. Coyne.

Võib seal midagi pistmist olla toiteka või emaplaadiga, seoses sellega, et hiljuti läks juba teine kõvaketas läbi. Mõlemad on olnud identsed samsungi sata kettad. Esimene kestis 4,5a, teise ostsin kasutatult ja kestis mul 9 kuud. Mõlemaga muutus arvuti mega aeglaseks ja pilt tõksus. Format ei aidanud.
